The role of the plane bearing of the automobile shock absorber

The function of the plane bearing of the automobile shock absorber is to act as a link between the shock absorber and the car body to avoid direct friction. With the vibration, the direction will also sink. If there is power assist, the general direction will feel choppy when the car is off.
Steel balls rotate between the shaft ring and the race. It can only bear axial load in one direction and cannot bear radial load. Since the axial load is evenly distributed on each steel ball, the load capacity is large, but the temperature rise is large during operation, and the allowable limit speed is low.
The advantage of plane bearings is that due to the increased contact length due to the selection of high-precision cylindrical rollers (needle rollers), this bearing can obtain high load capacity and high rigidity in a small space; another advantage is that if adjacent parts When the surface is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surface of the needle roller and cylindrical roller used in DF plane needle roller bearings and plane cylindrical roller bearings is a modified surface, which can reduce edge stress. Improve service life.
The shock absorber is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact. If you have ever driven a car with a broken shock absorber, you can experience the car passing through The shock absorber is used to suppress the bouncing after every pothole and ups and downs. Without the shock absorber, the rebound of the spring cannot be controlled, and the car will have serious bouncing when it encounters a rough road. , when cornering, it will also cause loss of tire grip and tracking due to the vibration of the spring up and down
When the car needs to turn when turning, it needs a plane bearing. If the shock absorber plane bearing is broken, there will be abnormal noise when turning the direction at first.
