In order to control the movement of the vehicle or change its trajectory, practically all modern vehicles have in their design not only elastic but also dampable devices-shock absorbers. The shock absorber is one of the most important components of the front suspension. The purpose of the depreciation counter is to counteract the impact of impact bumps. The bonus depreciation has dampingthe variations of the suspension spring and serves as the guarantor of the reliability of the operation of the vehicle's shock absorber. The bottom end of the rack is attached to the turnkey and the top of the vehicle is attached to the body of the car.
Pivot bearings are part of the bonus rack post. These bearings are a variety of rolling bearings. They have been widely used in modern cars due to their universality, the perception of combined loads, high performance and simplified installation. The bearings bearings of the bonus rack are directly involved in the process of damping and amortization of the vehicle. Its main function is to carry out a mobile connection of the shock absorber with the body of a motor vehicle, in addition to influencing the accuracy of the wheel settings of the wheels.
Device and operating principle
The retaining bearings differ from the standard rolling bearings of the outer ring. In such a bearing, the rolling figures are cylindrical rollers, each of which is perpendicular to the previous and for protection separated from it by a separator. This design allows a particular bearings to take on the load from any direction.
Main bearings used in modern vehicles:
- A bearing with an embedded inner or outer ring. Such a bearing does not require flanges because it has mounting holes. In addition, the construction of the bearing bearings with the integrated ring has gaskets, which ensures constant accuracy of rotation, excluding the effect of the installation. This type of bearing may be used for both the outer and the inner ring.
- The bearing with the interior ring being separated for the outer rotation. In this model, the inner ring is removed and the outside is connected to the casing. This type of bearings is used where the accuracy of rotation of the outer rings is required.
- A bearing with the outer ring for its inner rotation. In such a bearings, the outer ring is removed and the inner ring is attached to the enclosure. This model is used where the rotation accuracy of the inner ring is required.
- Single-separated type of bearing bearing type. The outer ring in such a bearing is divided into one point, which increases the stiffness. Such a bearing is used to rotate the outer ring with high accuracy.
Operational issues
The failure of the post-depreciation pillar is generally detected when the vehicle is in motion. The main sign that the pylon of the Bonus Depreciation frame is faulty is a characteristic of the movement on the roughness of the road. If this is the first case, you need to verify the reliability of the support leg of the shock absorber rack. If the pillar is to be replaced, then the rubber damper and bearing bearing are replaced most frequently.
In the driving process, the bearings are under heavy pressure as it is holding back the shock level of the shock absorber. The condition of the bearings must be checked every 20,000 kilometers, and 100,000 km should be replaced by a mandatory replacement, as it is rapidly affected by constantly changing stress and compression loads, especially under adverse conditions.
The support leg of the modern machines consists of a rubber metal cell which cracks in the shock support of the shock absorber. The process of wear and tear is also exacerbated by changes in temperature, oil deposits and various contaminates. The worn (soft) rubber part is the best replacement, as it may cause problems in the ABS system, tyre tread damage, extraneous sounds when rotations and vibrations on the steering wheel.
The old bearings are the main reason for breaking the wheel angles. The old post of the cushioning rack is used to provoke rapid deterioration of the shock absorbers, helpers and couplings, springs, and other parts. Therefore, for security purposes, the shock absorber and supporting bearings need to be checked regularly.
