Whose suspension is on the Lada X Ray. Lada XRay will receive a lot of technical innovations in its design

Well, 10,000 km passed unnoticed during this time, except for the bursting barrel and replacing it under warranty, in principle, there was nothing new. Everything worked normally and predictably, as did my squeaking front suspension struts, which, with the first cold weather, began to thump and knock on potholes. I have already described this epic in the spring. What obyamnal super masters from afar frets that the problem is somewhere in the racks (roofing felts, roofing felts squeaked anthers), but the fact remains. There was a problem they just didn't want to deal with. They kept the car for several days and only lubricated the engine mounts from the repair. .??????????? And here only they. Oh my God. I thought. I. Although I have the education of a car mechanic, which I received in the distant 90-92 years and forgot a lot, but not to the point of madness. It was just idiotic. I specifically ordered the OD front struts and some other suspension elements. I waited for them for about a month and oops they came, I drive the car, I wait 3 days, although they agreed on 1 and agreed on a replacement in the rack assembly, and as a result, a curtain. You can pick up we have greased your engine mounts. Well, as a verdict, it seems like it began to thump less, go for a ride, it should diverge. Then why was the whole circus ordering parts. If they didn't understand anything.

Well, here's the backstory. I'm going to drive a car to these miracle workers one of these days. And I don't know what to expect. After all, the racks with the cold really began to thump. Personally, I'm leaning towards the original factory marriage. after 3 weeks of operation to start problems? Yes, this can not be, it's just a marriage. For some reason, others in my region do not have such problems with the suspension, but they are worn on fishing trips and they have more rolling. And I just ride the house for work. Well, I poured it out. Unsubscribe as soon as I tell a fairy tale repairmen. But I still suspect that they can compose it for a long time absolutely without being engaged in the machine. Although here with the tank they really surprised me. Everything was done promptly. Except for the fact that I had to go to the city twice. One to troubleshoot. And the second swarm so that the guarantor took a photo, because. he had no contact with the plant for the first time. So it’s not close to go and I had to ask for leave from work twice. Although I was assured that everything was done for me so that I left by car and not on foot. Otherwise, supposedly, you would have to leave the car to wait when there will be a connection with the plant. But on my word of honor that I will come again for the photo session, everything was eliminated. Well, in my conscience, I could not break this word so I went to them a second time.

Well, as for the operation of the machine, I still like the machine, if only I would have dealt with this initial marriage of the front suspension. After all, if it weren’t for a guarantee in any car service, it was sorted out in a day and marokib didn’t know.

If, in comparison with the human body, the role of the heart is attributed to the engine, then the chassis and suspension can rightly be called legs.

Good platform

One of the most long-awaited innovations of JSC "AvtoVAZ" quickly joined the general Russian automobile flow. High hatchback Lada X Ray, as expected, has become one of the most popular domestic cars in 2016. The new car is practically no different from compact SUVs. Still, manufacturers are somewhat wary of the name of the crossover.

The wheelbase of the Lada XRAY is 2592 mm and has a fairly solid ground clearance of 195 mm. The front and rear tracks correspond to 1492 and 1532 mm. Such indicators fully satisfy the requirements of small all-terrain vehicles that can confidently overcome the difficulties of country roads, not get stuck in the mud and not be afraid of snow drifts. Sixteen-inch alloy wheels of the Lada X-Ray also contribute to this. It is impossible to ignore the successful distribution of masses between the axles of the car. With a total weight of 1650 kg, the proportions are 51 to 49%.

Front-wheel drive puts the status of "SUV" under a big question. What is suitable for the city is not enough for driving on complete off-road. Therefore, Lada XRAY is officially called a high hatchback. Although the mention of "compact" or "urban crossover" is heard no less often.

Peculiarities

AvtoVAZ designers did not puzzle over the creation of something unique. The Renault Sandero base was chosen as the platform for the compact crossover. Reliable and practical, it fully met the requirements for innovation from the Russian auto giant. It only remained to make changes, many of which became unique.

Front suspension

As a front suspension, an independent option was chosen for the Lada X Ray. In this case, each wheel has its own mount and a system that reduces vibrations. The rest of the wheels are not affected. The general meaning comes down to the absence of a beam or bridge, which are the connecting links of the suspensions.

MacPherson strut is one of the most proven and reliable. Its application allowed to increase the controllability of the car. The advantage of this option is simplicity. The hub is connected to the body with hinges and levers. They are responsible for the sensitivity and reaction of the car to the steering wheel.

In X-style cars, VAZ engineers used L-shaped levers. This system is very popular in sports models where handling is the price of victory. Prior to this, AvtoVAZ used saber-shaped levers. They work in the suspensions of Lada Granta, Kalina and Priora. The L-arm is one of the most rigid designs, increasing the sensitivity of the entire system. For production, cast iron and high-strength steel are used, so this element works reliably for a long time and has a large endurance resource. Until now, there are disputes about the authors of such a development. A similar scheme is on the Renault Logan, but AvtoVAZ claims that the front suspension of the Lada X Ray is a purely Russian invention, although it clearly could not have done without the support of the Alliance.

Rear suspension

As a rear semi-independent suspension of LADA XRay, a widely used torsion-lever version is used. In this case, the fastening to the torsion beam, working on twisting, is carried out using trailing arms. The difference from the previously used options lies in the separate location of the racks and springs. This scheme was created by Audi back in the late seventies of the last century. Now it is equipped with almost all passenger cars with front-wheel drive.

Rear suspension Lada XRay has many advantages, such as:

• Small mass;
• Ease of service and repair;
• Excellent kinematic performance.

It should be noted that for X-style cars that will have all-wheel drive, AvtoVAZ has its own rear axle project.

shock absorbers

Manufacturers made full use of modern approaches and technologies for their new Lada products. So, in the rear suspension of the Lada X Ray, S-shaped springs are used, which are supplied by Mubea. Their feature is a bent reference coil. Gas shock absorbers provided by Tenecco.

brakes

The braking system is an important part of the running gear of a car. The safety of both the passengers of the vehicle and those around them depends on the reliability of its operation. As the front brakes of the Lada X Ray, manufacturers have chosen ventilated disc brakes. They have somewhat increased the cost of the car, but guarantee a longer and more reliable operation. The rear wheels are equipped with proven drum brakes. They have proven themselves well on the Lada Granta and Lada Kalina. This scheme is usually applicable to dependent suspensions and is somewhat outdated. The Lada X Ray crossovers use rear disc brakes made of aluminum. In the future, all AvtoVAZ vehicles will also receive the same type of braking system.

Driving performance LADA XRay

With its small dimensions, wheelbase and track, the compact crossover behaves confidently in megacities. This is especially felt when driving in traffic jams. Also, one should not forget the narrow paths of the adjoining territories and the tightness of the parking areas. Chassis, together with comfortable seats and good sound insulation, allow you to get decent comfort for passengers.

As for the out-of-town cycle, everything is not clear-cut here. High ground clearance and short overhangs make it possible to confidently overcome steep climbs, force small pits and potholes. Snow and mud are practically no trouble for the new hatchback. Judging by the reviews, the car confidently holds the road and is sensitive to steering movements. Some drivers note the rigidity of the car. But this factor allows you to better control the car, especially in extreme conditions.

Do not forget that manufacturers have equipped new machines with systems that make driving much easier and safer. Among them, the system of exchange rate stability (ESC) can be noted. It keeps the car on a straight line and prevents skidding. Such assistance is especially needed at high speeds or when driving on slippery surfaces. ABS works in conjunction with this system.

The traction control system constantly monitors traction while driving to ensure stability and smooth vehicle maneuvers. The general meaning of the operation of this circuit is reduced to adjusting the supply of fuel to the engine compartment, when signals are received from numerous sensors that monitor the position of the car on the road.

All these systems work equally well with cars equipped with both automatic transmission (AMT) and manual transmission.

Currently, everyone is waiting for the all-wheel drive version of the X Ray, which is scheduled for release in late 2016, early 2017. With 17-inch wheels and both drive axles, the Lada XRAY crossover will take its rightful place among middle-class SUVs.

Suspension tests

This procedure is mandatory for putting the car into operation, and can also be applied after a major overhaul. During the tests, the strength of the structures is checked. Particular attention is paid to elastic elements. For testing, special laboratories are used to create loads on different parts of the chassis, simulating various traffic situations. At the moment, AvtoVAZ has test benches capable of revealing errors in manufactured products to the smallest detail. This allows you to get information about the shortcomings long before the release of the car from the assembly line and eliminate them in advance.

The next step in checking the chassis are road tests. For this purpose, appropriate tracks and polygons are allocated, where cars are tested in critical situations. The suspension is tested in off-road conditions, with an increased mass of cargo, sudden changes in speed.

Chassis malfunctions

The undercarriage of the car is constantly in operation under load. This happens even when parked, when the entire weight of the body and equipment puts pressure on the base frame and shock absorber springs. What to say about the loads during the movement. They act on the suspension in all directions. This is especially evident when driving over rough terrain, when all parts of the chassis work in extreme modes.

The creators of the new generation Lada X have invested a lot of effort to make a high quality car. However, the chassis of the new compact crossover is just as prone to failure as similar systems in other cars.

Among the most common breakdowns, the following should be noted:

• Changing the shape of the levers;
• Wheel alignment mismatch;
• Decrease in depreciation (weakening or destruction of springs);
• Damage to shock absorber mounts;
• Wear of rubber parts, bushings, ball joints, etc.;
• Shock absorber oil leak.

The most common causes of such malfunctions are bad roads, on which each suspension element experiences the greatest load. Another reason may be poor-quality suspension elements and natural wear of parts during long-term operation.

Usually, malfunctions are clearly manifested when a sharp collision with an object. The suspension often suffers during a collision. Troubles can be caused by pits and potholes. If you do not deal with the breakdown in a timely manner, then one detail entails the failure of the entire mechanism, which subsequently affects the cost and duration of the repair.

Symptoms of problems in the running gear of cars

• Handling deteriorates, the car pulls to the side when driving in a straight line;
• The machine retains oscillatory movements for a long time when starting and stopping or when cornering;
• There is a knock, uncharacteristic noise and vibration felt in the cabin;
• Tires quickly become unusable, and this happens unevenly.

If these discrepancies are found on the car, you should immediately use the services of a car service, since the further operation of the car will not only aggravate the situation with the repair, but will also affect the overall safety on the road.

The Lada XRAY is assembled on the B0 platform, so the design of the front suspension is largely unified with Renault cars. Renault Duster turned out to be the most reliable suspension from this line of models. Consider the features of the front suspension on the Lada XRAY and try to determine its reliability.

DESIGN FEATURES OF THE FRONT SUSPENSION LADA X REY

The front suspension of the Lada XRAY is independent with telescopic shock absorbers, wishbones and a torsion-type anti-roll bar.

suspension strut consists of shock absorber strut, coil spring, upper spring cup and upper strut mount. Outside, a steering knuckle mounting bracket is welded to the strut housing.

The strut spring with its lower coil rests on the lower support cup, and the upper coil rests on the upper support cup fixed on the shock absorber rod. Also on the shock absorber rod is an upper support and a thrust bearing. The bearing allows the strut, together with the spring and the upper spring support cup, to rotate when the steering wheel is turned, and the rubber cushion prevents the transmission of vibrations to the car body.

The front suspension struts are attached to the car body with a nut through a thrust washer. To protect the shock absorber rod from dirt and dust, a protective cover is installed on it. To protect the car body from sharp shocks during suspension breakdown, a compression stroke buffer is installed on the shock absorber rod.

From below, the rack is attached to the steering knuckle with two bolts and nuts, and the steering knuckle is attached to the front suspension arm through a ball joint.

A double-row ball bearing is pressed into the hole of the steering knuckle. The wheel hub is pressed into the inner ring of the bearing.

The front suspension arm is attached through a silent block to the front subframe.

Spherical bearing consists of body, pin and liners. At one end, the support pin has a spherical shape, and at the other end, it is conical with a threaded tail. The conical part of the finger is attached with a nut to the eye of the steering knuckle.

The spherical end of the finger is installed in the liners of the body. The connection is protected by a rubber boot.

During operation, the ball joint experiences heavy loads, which wear out its rubbing surfaces, which leads to an increase in the gap between the support body and the pin. As a result, the finger begins to move along its axis, and a knock appears. The rupture of the protective cover will lead to intensive wear of the ball joint, as a result of which dirt and moisture will inevitably get inside. If the support is not replaced in time, it can collapse and cause an emergency.

Roll Stabilizer consists of a steel rod of round section and two racks. The stabilizer bar is fixed through rubber cushions on the front subframe, the end of the bar is connected to the front suspension arms with the help of stabilizer struts.

An anti-roll bar is needed in order to reduce the roll of the car when cornering. This improves handling and increases the average vehicle speed. The anti-roll bar is essentially a torsion bar that connects the suspension elements of the right and left wheels. In turn, it twists, reducing roll. At the same time, the tendency to rock the car is reduced.

During the operation of the car, the stabilizer bar and its mounting pads wear out slowly and do not require frequent replacement. Carrying out operations to remove the stabilizer bar and replace the pillows is associated with a number of difficulties and is performed on the removed front subframe. Therefore, in the event of a malfunction, it is advisable to contact the service station. The main load is taken by the hinges of the stabilizer struts, so they fail much more often.

Recall that during the life tests of the Lada XRAY, the compression stroke buffers combined with the anther (20,000 km of run) first failed, and then the shock absorbers themselves failed. For 100,000 km of run in the front suspension, the front stabilizer struts also had to be changed. Such a result for a car that is assembled on the B0 platform is not very good. And what feedback about the front suspension of Lada XRAY can you leave?

A hallmark of the Xray, which should be carried over to the rest of Lada's future releases, is the X-shaped front end, designed by former Mercedes-Benz and Volvo designer Steve Mattin (a number of automotive experts believe it was borrowed from Mitsubishi). The front of the hatchback is decorated with the latest head optics with LED DRLs, larger than the headlights of Lada Vesta, and on the side there is a stamping made in the shape of the letter “X”. You can distinguish Xray from its French “brother” on the Renault Sandero platform by the absence of too flat body parts, a high glazing line and a sloping roof, as well as a more spacious luggage compartment with an electric opening button, a huge gas tank hatch and the presence of a third tinted glass in the top configuration.

On the far from outstanding dimensions of the “stern”, the letters L A D A are not widely spaced from each other (the distance between the letters is clearly larger in Vesta) and taillights with a rather controversial design. As for the rims, they are 16-inch in the “base”, and 17-inch are offered for a surcharge. Dimensions are generally unimpressive, and the car, alas, does not create the impression of an urban crossover - for this it is small and narrow. However, in terms of the suspension and the feeling behind the wheel, the Xray is still a bit like an SUV, and even a specific Opel Mokka.

Design

Adaptation to Russian conditions

Already after the first trip to the Xray, you are convinced that this is nothing but a small workhorse, which definitely outperforms the Sandero “co-platformer” in price and is not afraid of our dead roads, even despite the lack of all-wheel drive. Unfortunately, the appearance of an all-wheel drive transmission is not expected, since in order to introduce it into the B0 "cart" the manufacturer would have to completely redo the rear suspension, as in the case of the Duster, since the elastic beam, gearbox and driveshaft do not fit well, and this is fraught with high costs. for a car factory. The declared ground clearance is 195 mm, but in fact it is approximately 185 mm, which, in principle, is quite normal for operation in difficult Russian conditions. Also, one cannot but rejoice that the bottom of the car is even - no protruding muffler pipes are visible, the engine compartment is reliably protected by iron, and the thresholds are located at the optimal height, making it not so easy to damage the body on a summer dirt road or a snowy road.

Comfort

The doors of the car open quite wide, which ensures a comfortable fit into the cabin. The second row is a bit cramped, but the rear sofa itself is very comfortable. The front is freer, the first-row seats borrowed from Renault are distinguished by high-quality finishes, a shortish seat and the presence of a heating function. The driver's seat is for the most part well-organized, only the driver's door glass does not have automatic opening in any of the trim levels. The salon is completely trimmed with high-quality plastic and decorated in dark and light colors. The steering wheel is also made of plastic, and the front panel with stylish air duct deflectors is made using a seamless technology.

The Xray doors have more expensive handles than the Renault Sandero and continue the X theme on the inside, as do the seats. The new shift lever of the robotic gearbox pleases the eye with a chrome finish (for modifications with a five-speed “robot” AMT). The Xray dashboard has the same wells as the Sandero, and the graphics and fonts are VAZ. The multimedia complex with a touch screen and a rear video review does not glare and guarantees excellent image quality - at the level of Volkswagen and Nissan. It is noteworthy that the sound of this "multimedia" is an order of magnitude better than that of Vesta. In the initial configuration, a conventional air conditioner is provided, and in the top one, automatic climate control is more efficient than the Vesta air conditioning unit. In addition, the cabin has a cooled glove box, narrow cup holders, a eyeglass case and an Era-Glonass emergency alert button on the ceiling.

In the basic version, only two airbags are expected - a driver's and a front passenger airbag with a shutdown function, as well as two rear headrests (expensive versions have three) and a set of electronic assistants, including:

The base Xray is equipped with a 2DIN audio system with radio (FM/AM with RDS function), CD player, four speakers, AUX and USB input for connecting mobile devices, Bluetooth and Handsfree. But the top versions have at their disposal a multimedia complex with a seven-inch color touchscreen, six speakers and navigation. Thanks to this complex, you can view the image from the rear view camera, listen to your favorite music and talk on the phone without being distracted from driving. In general, this is a completely modern infotainment system with an intuitive interface and quite nice graphics.

Lada X-Ray Specifications

The range of hatchback engines includes VAZ gasoline "fours" with electronically controlled fuel injection. We are talking about a familiar 1.6-liter engine that produces 106 hp. and 148 Nm of peak torque, and a completely new 1.8-liter unit that develops 122 hp. and 170 Nm, calmly refers to the 92nd gasoline and in reality consumes 8-8.2 liters. fuel per 100 kilometers, while its passport consumption averages 6.8 l / 100 km. Both motors are combined with a five-speed manual transmission, but the 122-horsepower engine can be paired with a 5-speed AMT single-clutch robot that replaced the torque converter box. The most powerful modification with a robotic transmission accelerates to 100 km / h in 10.9 seconds, and its top speed is 186 km / h, which is a good indicator for a model in this class.

Structural changes in the suspension of Lada X Ray Cross compared to X Ray. Driving sensations and algorithms of the Lada Ride Select system.

Although the appearance of LADA XRAY Cross differs from the simple version of the hatchback, plastic lining and other components are immediately visible, due to which both cars differ.

But you can’t say the same about the Lada X Ray Cross suspension. Everything is the opposite here - there are a lot of changes, but just looking at the car you can’t see them in any way, with the exception of the clearance and other rims.

It must be admitted that AvtoVAZ marketers, claiming a large amount of changes in the chassis, were not cunning. The chassis of the Cross is strikingly different from that of the simple version.

Therefore, this aspect of the design of the model should be analyzed in more detail.

Changes

Suspension Lada X Ray Cross received an improved front subframe, which was lowered by 15 mm, which increased the ground clearance by the same 15 mm. In addition, the ground clearance has increased by another 5 mm due to the installation of large wheels. There were other shock absorbers and springs.

Suspension changes

The car received other L-shaped levers. They are very similar to those that are on the West, but differ from them. The anti-roll bar has also been replaced.

XRAY Cross got electric power steering, while the simple X Ray has an electro-hydraulic one taken from Renault. Vesta has an electric amplifier from NSK, but the XRAY Cross received a component from the Autoelectronics plant in Kaluga. Steering racks are supplied by the Steering Systems company from Tolyatti.

The CV joints and steering knuckles of the model are also different, which, naturally, forced AvtoVAZ to reconfigure the wheel alignment angles - a negative value of the rolling shoulder was set. It did not take long to have a positive impact on exchange rate stability.

In the rear suspension of the Lada X Ray Cross, there are new levers that were needed after equipping the car with disc brakes on the rear axle, which were inherited from Vesta.

The steering wheel is adjustable for both height and reach.

All versions of the XRAY Cross received a steering column that is adjustable in height and reach, which is not the case with a simple X-Ray. He also has exclusively 17-inch wheels with a rubber dimension of 215/50 R17. Disks do not fit from a regular XRAY, because they have a different offset.

The car received other rims

Driving sensations

Of course, given all these changes in the Lada X Ray Cross suspension, it rides in a completely different way.

The car has become much better to keep a straight line on the track, and behaves much more obediently in a rut. There is a clear “zero” on the steering wheel, and in order to “move” the steering wheel, you need to make a noticeable effort, while returning back to “zero” even seems to some to be redundant. Of course, there are rolls, given the clearance of 215 mm, but they are small and do not interfere with taxiing.

Fans of AvtoVAZ models have always appreciated the energy intensity of the chassis of domestic models. And here the Lada X Ray Cross suspension is beyond praise! On a flat surface, the car shakes a little. But everything changes on a broken road. Even before serious bumps and influxes, you can not slow down the speed!

However, it is worth remembering that the engine protection here is plastic. In fact, it only protects against dirt, small stones and grass. Therefore, if you intend to at least periodically drive off asphalt, it is strongly recommended to install metal protection.

Lada Ride Select

This is an electronic complex, which, according to the designers, should compensate for the missing all-wheel drive. It has several driving modes.

In Sport mode, pressing the gas pedal becomes more sensitive, and even after removing the foot from it, the speed does not drop so quickly as to have time to pick it up after switching on the next speed.

Lada Ride Select

Sand mode activates the electronic lock. When the machine is suspended, the stabilization complex transfers more traction to the wheel that has traction, while holding the free wheel. This allows you to continue moving or escape from the sand trap.

X Ray Cross confidently rides on the sand

If, however, the Lada X Ray Cross suspension is switched to the “Snow” mode, the traction reduction system begins to prevent even slight wheel slip, which allows it in “Sandy”. Yes, and start moving on a slippery surface a little easier.

As you can see, the chassis was seriously redesigned, which was not slow to bear fruit. However, this also affected the cost. The price of LADA XRAY Cross starts from 754,900 rubles and goes up to 913,900 rubles. And this despite the fact that the version with AMT has not yet entered the market, which will become even more expensive.

It is not surprising that in light of such prices, all-wheel drive can be forgotten. After all, if it appears, the price tag will go for a million rubles, which will make the prospects of the model very vague.
