Where is the Plane Bearing Located?
1 Answers
Automotive plane bearings are located at the top of the shock absorber, together with the shock absorber top rubber. Plane bearings, also known as pressure bearings, are most commonly found in MacPherson-type suspensions. Plane bearings consist of a flat cage assembly with needles, cylindrical rollers, or steel balls, and flat washers. More details are as follows: 1. Plane bearings in vehicles serve as a shock-absorbing and movable connection between the car body, preventing direct friction between shafts. The advantages of plane bearings include: high load capacity and stiffness in a compact space due to the use of high-precision cylindrical rollers, which increase contact length. 2. Another advantage is that if the surface of adjacent components is suitable as a raceway, the washer can be omitted, making the design more compact. DF plane needle bearings and plane cylindrical roller bearings use profiled surfaces for needles and cylindrical rollers, reducing edge stress and extending service life. 3. Plane bearings primarily bear axial loads in assemblies and are widely used. Although the installation of plane bearings is relatively simple, errors often occur during actual maintenance, such as incorrect positioning of the bearing's tight and loose rings, leading to bearing failure and rapid wear of the shaft neck.
