I would like to ask the car transmission inside the thrust washer (thrust washer) is used to do ah?
Figure 3 thrust washers, 4 needle bearings, thrust washers to prevent excessive wear of the main bearings, the usurper.
Differential gear thrust washer is composed of silver alloy pressing, as well as plastics. Planetary gear thrust washer and half axle gear thrust washer shape are concave spherical and planar surface, there are many patterns like grooves or concave point in oil storage. The washer is the role of the friction reducing gear and axial differential housing, improve the transmission efficiency of the differential protection shell, thrust face not excessive wear, to prolong the service life of the differential housing, and maintain the normal meshing and transmission differential gear. The reason for the failure of the thrust washer is a serious lack of lubricating oil, or because of the small size of the stay and the erosion. Planetary gear broken, cross shaft fracture caused by the thrust washer damage, is generally rare. When the vehicle is traveling on a special road, or when the vehicle is in the mud, the differential frequency is used, resulting in excessive wear and thinning of the thrust washer. Thrust washer wear will make gear thrust surface shell, thrust surface acceleration loss, the differential gear axial shift, gear meshing clearance increases, the transmission space increases, causing the gear, cross shaft, differential housing bearing seat hole damage. Thus, the thrust washer is a reliable guarantee of differential action, but also to extend the life of differential parts. To this end, the vehicle should be updated on a regular basis when the thrust washer, to restore its proper clearance, to ensure the normal operation of the differential.
Transmission in order to reduce the noise, the general design of gear teeth, which in the operation of radial force, thrust washer is to prevent excessive wear of the gear side!
