- front struts for Lada Vesta... Pay attention to the mount, to the right are the racks from Granta.
Thanks to the "insider" we learned that the novelty will receive new gas struts produced by the Skopinsky AvtoAgregatny Plant. It is noted that all configurations will be on gas struts. Many will notice that on Lada granta \\ Kalina in the "luxury" configuration, as well as on sports versions gas-filled struts have been installed for a year now, but for Vesta they have a different design and settings, and the suspension itself is a development that has not yet been used on AvtoVAZ cars (prepared for Project C).
For reference:
Gas-filled racks work harder, but are more stable and more durable. Unlike their counterparts (oil-filled racks), the compensation chamber of these shock absorbers is filled not with ordinary air, but with gas, which is pumped into it under very high pressure - up to 28 atmospheres. Thanks to high pressure, the shock absorber piston is always compressed. This makes it possible to react much faster to the shortcomings of domestic roads. Moreover, a single-tube shock absorber, unlike a hydraulic two-tube shock absorber, cools better, therefore, it works more stable.
For comparison: this is how the front suspension struts look like for Lada Granta, Kalina and Priora.
We would also like to note the change in the parking brake on the Lada Vesta, now it is not the same as before, more adapted, and, according to the sensations, will not require constant adjustment.
Lada Vesta suspension
Before that, a computer model of the Lada Vesta suspension appeared on the network, which is very different from the previous models of AvtoVAZ. The community was the first to publish this information Just lada :
The designers have finally moved away from the type of front suspension that has been used for the last 30 years (starting with the VAZ 2108 car) and switched to a subframe and L-shaped levers and a steering rack attached to it, which were previously attached to the engine shield.
The rear suspension remains fundamentally the same - as on the vast majority of modern front-wheel drive vehicles (and on all LADA with front-wheel drive), it is a semi-independent beam, but with one difference from the previous AVTOVAZ products: the springs are now spaced with shock absorbers.
A modern car must meet certain safety, convenience, handling, comfort, and cross-country requirements. The developers of AvtoVAZ tried to embody all this in their brainchild Lada Vesta. They created a fundamentally new design - front suspension Lada Vesta not modernized from previous versions, but a completely new invention.
In the production of their latest models the manufacturer for the first time in many years abandoned old ideas and brought new developments into reality.
Lada Vesta
The Lada Vesta SV station wagon is a long-awaited event that fans of the domestic car industry were looking forward to. The manufacturer offers the model in several trim levels, giving the consumer the right to choose, taking into account personal needs. At the same time, AvtoVAZ presented to the public two models at once in the back. In the line of cars, they appear as Vesta SV and Vesta Cross.
The vehicle is an original development of the manufacturer and is very different from previous versions. Technical characteristics provide cars with an excellent combination of handling, comfort and cross-country ability. Among motorists, the domestic station wagon is of considerable interest. And one of the reasons for this phenomenon is the front suspension of the car.
Lada Vesta suspension - device and distinctive properties
Car domestic production was tuned at the Spanish IDIADA test site. The manufacturer has set itself the task of achieving perfect interaction between the car and the driver. As a result:
- Transport confidently moves in a straight line. When driving, zero steering is felt perfectly.
- When cornering, the car does not shake, as well as during braking and acceleration.
- While driving, in any situation, a good connection between the driver and the car is maintained.
The Lada Vesta SV suspension has electronic assistants - aBS systems, EBD, ESP. Built-in stabilization makes it easier to move, provides full control over traction. The car is characterized by excellent cross-country ability, which is largely ensured by electronics and competent tuning of the car's suspension. Simulated differential lock allows you to overcome off-road conditions. The company received a lot of positive feedback for this innovation.
Front suspension Vesta
Front suspensionIs a completely original design that has been developed from scratch. It is based on gas-filled double-sided shock absorbers with coil springs, stabilizer bar and lower arms.
The design uses a universal L-shaped arm, which replaced the longitudinal stretch from previous versions. It copes well with various loads due to the use of castor at 5 degrees. A suspension detail such as a subframe with two support points for stretching attracts attention.
Rear suspension Vesta
Redesigned rear suspension electric car Renault Zoo. The model differs from its predecessor in the length of the beam. Trailing arms are also installed in the suspension, and domestic struts of Skopinsky origin are used.
Z rear suspensionmakes driving a car even more comfortable and safe due to the location of shock absorbers in the arches. The springs are located under the side members for increased comfort while driving.
Comparison of the suspension of the sedan and station wagon Lada Vesta
It so happened that for many years the weak link in VAZ cars was chassis... In its new product, the manufacturer offered a revised and improved version of its predecessors. Most of the changes were made to the front suspension. There are many new details, such as a subframe to increase the strength of the body, L-shaped arms made of quality steel.
The rear suspension designs are almost identical. In Vesta SW, the springs and shock absorbers have been modified, which increases the strength properties and allows them to withstand increased loads. The rear springs in the CW model are larger by 9 mm.
The differences between the suspension Lada Vesta SW and Lada Vesta SW Cross
The version with the Cross prefix differs not only in external qualities, but also technical properties... Outwardly, the model looks strong and brutal. But the ride quality doesn't always match the looks. To justify the name of the model, the manufacturer decided to change some structural units of the suspension, but did not experiment with the engine.
Suspension Vesta Crosshas several other shock absorbers. Here they are more rigid, although they are of the same type. The springs are longer and more rigid. Also, the developers have done some manipulations with certain settings. Changes in the parameters increased the severity of the reaction to steering, its position is felt more clearly. During the speed after the maneuver, the car quickly returns to its previous control positions.
Lada Vesta is a great achievement domestic manufacturer... Due to structural changes vehicle received higher handling, safety. This was achieved through the use of various innovations.
The reliability and technological parameters of the suspension are the most important characteristics of any machine. Lada Vesta is no exception here, because it was in this model that AvtoVAZ realized the advantages of the stabilization system and others technical innovationsthat really excited the domestic auto industry.
Even at the stage of car production, the designers set themselves the task of making a suspension that would allow, taking into account the peculiarities of domestic, alas, not the best roads, to ensure quality, reliability and excellent functionality - no worse than foreign counterparts. As a result, what happened was really worth the delight of all car lovers. It is all the more pleasant that it was created by domestic engineers.
front part
It is here that the vast majority of technological innovations are implemented. Let's try to consider them in more detail:
- The very approach to the location of the suspension was rethought, which eventually began to be attached to the underframe part of the car. The result is less vibration, less noise, greater geometry accuracy, and higher rigidity.
- The location of the steering rack was changed (it is located at the bottom), as a result of which the wheel rods interact with the hubs without any intermediaries. The result was the increased controllability of Vesta - in this regard russian specialists achieved a real comparison with foreign models.
- The castor angle has also been changed (now it is 5 '). Shock-absorber struts of the MacPherson type, the suspension itself is independent, the stabilizers are installed of a new type. In general, the entire system has a greater feedbackthan on previous models - as a result, the car has smoother handling.
Beam lateral stability the car has also undergone changes - the torsion bar now has a modernized shape, and its struts were made elongated, which further affected the quality of the car's control.
The suspension in front of it, thus, more than ever, corresponds to the domestic road surface, as a result, the car behaves predictably and confidently anywhere. Motorists who have already tested the car for domestic roads, they say that the suspension on Vesta is very smooth, and some argue that even the venerable brands (Rio or Solaris), the quality of the suspension does not reach the new Russian model.
Rear end
Our article would not be complete without considering the rear axle suspension. In principle, there are no serious improvements here, the manufacturing technologies are traditional, although several innovations are still present. In particular, these are the following:
- rear shocks and springs are now spaced due to new concept layout - by the way, this is a tangible step for the car plant in particular, and indeed for the entire domestic machine industry;
- suspension tuning was carried out at Renault in strict accordance with European standards;
- the track of the rear of the car is increased to 1510 mm, as a result of which wheel arches also changed in size up.
In general, it is quite clear that even with not so big changes, rear suspension without hesitation it can be called modern - therefore, convenience and smoothness of movement with the arrival of Vesta will become mandatory attributes of new domestic cars.
Changes in a number of systems and new stabilization
Not only are the innovations listed earlier more than enough to designate Vesta as a significantly modified car, other improvements and modifications can also be noted. For example, these are ESP, EBD, ABS. The steering booster is, say, the same as used by Nissan, the braking system contains parts from Renault (Logan and Megan). All together, this specificity provides Vesta with a well-deserved status and reliability.
Unlike its predecessors, Vesta's platform is completely original, and not an improved modification of the VAZ G8. The manufacturer announced this at the stages of model development.
At the moment, when the first "Vesta" have already rolled off the assembly line, and got on all kinds of test drives automotive experts, you can consider in more detail the features of its chassis.
The last settings and tests that the Lada Vesta suspension passed took place this winter at the Spanish IDIADA training ground, after which the car acquired the optimal combination of comfort, handling and safety. As a result, we have the opportunity to evaluate the results of the work of automotive professionals.
Front suspension Lada Vesta
This part of the suspension is absolutely different from other Lada models with front-wheel drive. It is radically different from all cars produced by the AVTOVAZ concern.
The main feature is the absence of the usual suspension stretch marks, which the designers replaced with full-fledged levers with a ball pin. The Lada Vesta suspension is attached to the subframe using reinforced rubber-metal hinges. The type of struts is the classic MacPherson strut common on foreign cars.
The front suspension Vesta is independent. Its main elements:
Shock absorber struts (gas-filled, double-sided)
Barrel-shaped coil springs
Suspension arms
Anti-roll bar
In addition, Vesta's suspension is attached to a subframe on which the engine support brace is supported. The other two attachment points for the motor are located on the side members. Having examined the suspension of the Lada Vesta photo, you can see that the levers are L-shaped, and differ from the familiar "eight" lever.
Their advantage is that they have a castor of 5 degrees and are able to withstand both longitudinal and lateral loads. This extends the life of the parts and improves driving comfort. In addition to this, manufacturers have used new steering knuckles that have significantly improved the vehicle's agility and handling.
Rear suspension
Lada Vesta, the rear suspension of which was originally planned as an independent multi-link, has a semi-independent twisted beam, which is also used in other Lada models with front-wheel drive.
Engineers at the last moment decided to reduce the cost of the car, and installed this design on Vesta.
The rear suspension Lada Vesta consists of the following parts:
Double-acting gas-filled shock absorbers
Trailing arms
Helical barrel springs
The rear suspension arms are resiliently connected to each other by means of a crossbeam and a stabilizer bar. This type of suspension is called semi-independent, with linked arms. Served as a base for Lada Vesta suspension with renault car Zoo. The developers slightly changed its dimensions, lengthening the beam, and thoroughly redesigned the structure. The shock absorbers of the car were placed in the arches, and the springs were placed under the side members.
Suspension test in real conditions
The innovations have significantly improved the car's handling. The main difference between the suspension is an excellent combination of comfort, agility and safety. The car responds perfectly to all the movements of the driver, and allows you to achieve maximum mutual understanding.
Driving on a straight road, the driver clearly feels the zero position of the steering wheel, and during turns, he can fully control the trajectory of entry. At the same time, during braking, increasing speed and other maneuvers, no jolts are felt in steering wheel, as was the case in previous VAZ models.
On an uneven road, vibrations from the body are absolutely not transmitted to the steering wheel. It lies well in the hands, and does not break out of the hands, even with strong shaking. This ensures safety and confidence when driving, which is proved by numerous test drives of the new car.
The hype around the novelty of the domestic auto industry - the station wagon Lada Vesta SV Cross has not yet had time to subside, but there is still not much technical information about the new product on the Internet. In particular, on our agenda today is the Lada Vesta SV Cross suspension.
So many questions about the suspension of the novelty arise due to the fact that Vesta's cross suspension device has radically changed compared to its predecessors. At AvtoVAZ, it was decided not to follow the old path and not to modernize the obsolete suspension, which was previously installed on Samara and Priory. Instead, it was developed new model, which is now installed on the entire Lada Vesta family. In particular, on the Lada Vesta sedan, the Vesta SV station wagon and the all-terrain version of the Vesta Cross SV.
Why was the new Lada Vesta SV Cross suspension needed?
Firstly, the old model of the VAZ suspension is outdated as in technicallyand morally. Yes, it was easier and cheaper to assemble new suspension station wagon on old components, reconfigure it and put it into series. But all car critics again would have crushed such a decision in their reviews and reviews.
Secondly, the new product was made practically from scratch, so new solutions were needed for a more comfortable ride and precise handling. For this, it was decided to develop its own model. Yes, most of the components and solutions in the suspension have been copied from foreign cars... But VAZ members deliberately chose this path. Why reinvent the wheel? It is much easier and more correct to take the best from foreign cars and embed it in your car.
Thirdly, the car was designed on a new platform and ready-made solutions from AvtoVAZ would no longer fit.
What is the bottom line? And in the end, we got a completely passable suspension, which is in no way inferior in dynamics, handling and comfort. foreign counterparts... Almost all car critics and experts speak about it. Yes, many components and assemblies were borrowed from Renault, but this is not so important. After all, at the exit we received a high-quality and reliable product at an adequate price. And from which car the parts - we, in principle, should not worry. And now critics will not be able to object at all that the suspension device has not changed since the days of the G8.
The front suspension device has undergone a number of changes compared to the front-wheel drive predecessors. Just compare how the suspension has changed:
First, a stretcher appeared on Vesta. This is the most important change, since none of the russian car He was absent. The appearance of the subframe means that the factory is thinking not only about the technical part, but also about the overall ride comfort. By itself, the subframe allows you to get away from the attachment of power units and walkers to the body, and therefore provide additional comfort and improve handling.
Secondly, a new anti-roll bar was used. This added a bit of control, but also allowed the load to be evenly distributed across the entire axle.
Thirdly, the stabilizer is now attached to the shock absorbers using links, which are struts with pivot points. Earlier on Priors and Samara "eggs" with rubber bushings were used. The use of ball ends allows you to improve the car's handling when cornering, thereby reducing roll.
Fourth, an L-shaped arm has been added to the design, which is attached to the subframe at two points. This made it possible to reduce backlash and jerks during acceleration and deceleration. Thus, in terms of suspension, it turned out to be knocked down and reliable car... And the suspension itself does not differ in some kind of loading and a large number of parts.

Rear suspension Lada Vesta SV Cross
In the rear suspension of the Lada Vesta Cross, as well as in the front, new solutions were used. Although it is difficult to call it completely new. The entire rear suspension of the car was borrowed from Renault Megane... In this case, we have a semi-independent suspension, which has been additionally strengthened, and the track has also been increased. The shock absorbers, as before, are located in the banks behind the arches, but the springs were placed under the side members.
On a simple civilian station wagon, there are standard drum brakes at the back, and disc brakes on the crossover version. The choice in favor of drums for the simple version is due to the fact that under normal conditions disc brakes are not needed, and drums are in no way inferior to them. And it is more economically profitable to play simple drums than discs. Besides, drum brake more protected from dirt, so its service life will be increased.
Initially, the plant considered the possibility of installing a rear on the Lada Vesta SV independent suspension, but after preliminary calculations of the costs, they decided to abandon this option. The very fact that a semi-independent suspension was left behind suggests that in the near future one should not expect four-wheel drive on West Cross and SV.
Differences between the suspension Lada Vesta Cross and Lada Vesta SV
Many people think that the station wagon and the off-road version are not much different. The main differences lie, of course, in appearance. New body kits were installed on the all-vehicle version of the Cross, slightly changed appearance exhaust system, slightly altered the interior. However, these are not all changes.
The most difficult moments concerned the suspension. The point is that the prefix Cross in the name should be deserved. Here I had to play a good deal with the suspension. Firstly, the parameters of the wheel tilt and castor angles were reconfigured.
Secondly, new shock absorbers were used. Their type has not changed, but the length has increased slightly. The racks have become more rigid and knocked down.
Thirdly, the springs also had to be lengthened. Due to all these manipulations with the suspension units, the car rose by 2.5 cm. In order not to lose stability, it was decided to widen the track by 1.4 cm. All this, and also improved the handling of the car as a whole.
At the moment, it is too early to say any reliability and suspension resource of the Lada Vesta SV Cross - the cars have left too little. But some conclusions can be drawn.
Based on enthusiasts, automotive publications and auto clubs, it can be understood that weak spots the suspension of the Lada Vesta Cross still has. Firstly, during intensive operation on uneven roads, shock absorbers begin to leak already at 25-30 thousand kilometers. Secondly, the silent blocks on the rear beam become unusable already at 20 thousand kilometers. Thus, they can be considered a regular consumable and changed after two oil changes. Although the plant stated that the suspension on Vesta SV and Cross would not cause problems to owners for at least 5 years or up to 100,000 km.

Conclusion
After reviewing the Lada Vesta SV Cross suspension, I would like to complete our article, which turned out to be very extensive. There is more to say. But, perhaps, we will round off. Thank you for your attention and see you soon on our website.
