Compact crossover Sollers AtlantThe slate, which debuted on the Russian market, became a landmark event for the domestic automotive industry, offering a modern platform at an affordable price. However, like any car created with an eye on the economy segment, it requires careful attention to the chassis, especially in conditions of Russian roads. Front suspension Here it plays a key role, providing not only comfort, but also driving safety, as well as stability of the course at high speeds.
Engineers classic circuit McPherson, which is the standard for this class of cars, but implemented a number of design solutions aimed at increasing the resource of the units. Understanding exactly how it is arranged running-piece Your crossover will allow you to predict possible malfunctions in advance and avoid expensive repairs in the future. In this article, we will discuss in detail the node architecture, typical problems and algorithms for their elimination.
Owners should take into account that the resource of parts directly depends on the style of driving and the quality of the road surface. Ignoring the first signs of wear can lead to the destruction of adjacent elements of the steering system. A critical parameter for the durability of the Atlant suspension is the timely replacement of the Silentblocks at the first signs of their stratification. Let's dive into the technical details.
Design features of the front suspension
Front suspension base Sollers Atlant It is an independent stand of the McPherson type. This layout is not chosen by chance: it provides excellent compactness, which is important for the lateral location of the engine, and has good repairability. The main bearing element here is a transverse lever that perceives the main loads when moving.
The construction used forged-leverThis increases their strength to tear and bending compared to stamped analogues. This is especially true when passing deep pits or hitting curbs. The transverse stability stabilizer is attached directly to the levers through the racks, and its ends are closed in special eyelets, which allows you to effectively combat body rolls in corners.
When buying parts, pay attention to the items, as early and later versions of the model may have differences in the mounts of the stabilizer.
The depreciation rack is assembled in a single block with a spring. The spring rests on a cup of lever through a rubber cushion, which reduces the transmission of vibrations to the body. The rotating fist is connected to the two bolts, which allows you to adjust the wheel breakup by changing the length of these bolts or installing adjustable elements.
Typical malfunctions and their symptoms
Operating a car in harsh conditions sooner or later leads to wear of suspension elements. The first signal of problems is usually foreign sounds. Deaf knocking when passing irregularities often indicates production in Silentblocks or ball supports. Screaming may indicate drying of rubber metal hinges.
If the car began to move aside when moving in a straight line, it is necessary to check the angles of installation of the wheels and the condition suspension-lever. Curvature of the lever after a strong blow is a frequent phenomenon that cannot be corrected by editing, only replacement is required. Also, the cause of withdrawal can be a different degree of drawdown of springs or uneven wear of tires.
⚠️ Note: Operation of a car with a faulty ball support is strictly prohibited. Rupturing the hinge on the move will lead to an uncontrolled wheel turn and create an emergency situation.
Vibration on the steering wheel, especially at high speeds, is often associated with wheel imbalance or disc deformation, but can also be caused by backlash in the hub bearings. It is important to carry out a comprehensive diagnosis so as not to change the working details. Below is a table of the main symptoms and probable causes.
| Symptoms. | Probable cause | Action required |
|---|---|---|
| Knocking on small bumps | Wear of stabilizer racks | Replacement of pillars |
| Screaming when steering | Dry Silentblocks | Lubrication or replacement |
| Move the car aside | Lever deformation | Lever replacement + collapse-convergence |
| Braking knock | Luft in the Silentblocks of Lever | Pressing new Silentblocks |
Diagnostics of the condition of nodes
For accurate detection of malfunction, the car must be lifted on the lift or driven to the observation pit. Visual inspection begins with an anther check. If cover-case ball supports or shock absorbers are torn, dirt and moisture enters the inside, which sharply reduces the resource of the node. The presence of oil undertights on the body of the shock absorber indicates its failure.
Then there's the backlash check. Swinging the wheel with your hands in vertical and horizontal planes, you can determine the wear of the bearing of the hub or ball support. The use of an mounting blade allows you to identify hidden backlashes in the Silentblocks of levers. When pressing on the lever at the place of attachment of the Silentblock there should be no apparent displacement of the rubber relative to the metal sleeve.
Particular attention should be paid to the condition of the springs. Corrosion of turns can lead to their breakage and damage to the tire or body. Cracks on rubber bumpers also require attention, since without them the shock absorber works without limiting the course of the breakout, which leads to its rapid failure.
How to check the shock absorber without removing?
Press hard on the corner of the car and let go. The body must return to its original position and stop. If the swing has begun, the shock absorber is defective.
Replacement of front levers and silent blocks
Front suspension repair Sollers Atlant most often involves the replacement of levers in the collection or overpressing of Silentblocks. Replacement of the lever assembled with a new ball support is a faster and more reliable option, eliminating errors during pressing. However, if the budget is limited, only rubber metal hinges can be replaced.
The process of removing the lever requires dismantling the wheel, disconnecting the stabilizer rack and the lower support of the shock absorber. The use of penetrating lubricant and preliminary heating of threaded joints with a burner (with caution) will facilitate the work. After installing a new lever, adjustment is required. wheel-mounting angles.
When pressing the Silentblocks at home, it is necessary to use a special tool or a high-power vice. Incorrect installation (skew) will lead to rapid destruction of the new part. The direction of installation of the Silentblock is important: often they have "Front" labels or color tags that should look in a certain direction.
☑️ Tools for lever replacement
Maintenance of shock absorbers and springs
Amortization racks are consumables, the resource of which in our conditions rarely exceeds 60-80 thousand kilometers. The replacement is made in pairs on one axis, even if the second rack seems still working. This ensures uniform braking and stability of the car. Before installation, new shock absorbers must be "pumped" - several times compressed and decompressed in an upright position.
The springs change less often, but their condition must be monitored. The sown spring changes the geometry of the suspension, which leads to accelerated wear of other parts. When replacing the shock absorber, it is recommended to change the upper support with a support bearing, since when disassembling the unit, they are often damaged or already have production.
⚠️ Warning: Never use low quality spring screeds. When the hook is off, the compressed spring has tremendous energy and can cause serious injuries or damage the car.
The assembly of the unit is carried out in reverse sequence. All threaded connections are recommended to be treated with a thread fixer or replace the bolts with new ones, if required by the regulation. The final tightening of the shock absorber rod nuts and lever bolts is only made after the car is lowered on the wheels to avoid premature wear of rubber elements.
Replacement of shock absorbers is always made in pairs on one axle to maintain the balance of driving qualities of the car.
Adjustment of wheel mounting angles
After any interference with the geometry of the front suspension Sollers Atlant It is necessary to adjust the angles of installation of wheels (fall-down). In this model, only the angle of collapse of the front wheels is regulated, which changes by shifting the bolts of the shock-absorbing rack to the rotary fist. The angle of the longitudinal inclination of the axis of rotation (caster) is not structurally adjusted.
Incorrectly exposed corners will lead to "eating" rubber, moving the car to the side and unstable behavior on the track. Modern stands allow you to set the parameters with high accuracy. Before entering the stand, it is necessary to check the pressure in the tires and the absence of backlashes in the steering and suspension.
The procedure takes a little time, but requires a skilled craftsman and good equipment. Ignoring this stage after the suspension repair negates all the effort and costs of new parts. Regularly checking corners (once a year or when replacing parts) will prolong the life of your tires and ensure safety.
Frequently Asked Questions (FAQ)
What is the front suspension on Sollers Atlant?
Resource depends on the operating conditions. In the city, Silentblocks and stabilizer racks can walk 40-60 thousand. km, and shock absorbers up to 80 thousand. km. On bad roads, these numbers can be much lower.
Can I drive with a knock in the suspension?
Short term, yes, if it's just the wear of the stabilizer racks. However, constant driving with extraneous sounds accelerates the destruction of other nodes, such as ball supports and steering tips, which is dangerous.
Do I need to go down after changing the levers?
Yes, I will. Replacing the lever or Silentblock changes the geometry of the suspension. Without adjusting the angles of the wheel installation, you risk quickly wearing new tires and getting the car sideways.
Which Silent Blocks Are Better: Rubber or Polyurethane?
Rubbers provide more comfort and less vibration. Polyurethane is more durable and stiff, which improves handling, but reduces comfort and wears out other metal suspension parts faster.
