Abstract

The invention discloses a preparation method of an antifriction gasket for an automobile driving shaft assembly. The preparation method comprises the following steps of a preparation method of a gasket framework and a preparation method of a surface polytetrafluoroethylene wear-resistant layer, wherein wear-resistant particles comprise, by weight, 50-60 parts of quartz sand, 20-30 parts of brown fused alumina, 10-15 parts of molybdenum disulfide, 1-5 parts of graphene, 2-3 parts of diamond, 0.1-0.5 parts of zirconium oxide and 2-3 parts of aluminum oxide. According to the preparation method ofthe obtained antifriction gasket for the automobile drive shaft assembly, the antifriction gasket is arranged at the position of the matching part of an outer ball cage, so that the starting abnormalsound of a vehicle is effectively eliminated, and the using performance of an automobile is improved. Meanwhile, the surface polytetrafluoroethylene coating has the functions of wear resistance and noise elimination, and the automobile starting abnormal sound is eliminated.

Description

technical field [0001] The invention relates to a preparation method of a washer, in particular to a preparation method of a friction-reducing washer used in an automobile drive shaft assembly. Background technique [0002] The car drive shaft assembly is an important component of the car. One end of the car drive shaft is connected to the universal joint of the power output end of the car gearbox, and the other end of the car drive shaft is connected to the universal joint of the power input part of the car wheel. The car drive shaft The role of the car is to transmit torque between the car gearbox and the wheels. [0003] In the existing drive shaft assembly, when the vehicle is started, the reference end surface of the outer spherical cage of the drive shaft and the end surface of the hub bearing start to rub against each other instantaneously, resulting in abnormal metal friction noise, which seriously affects the performance of the vehicle.
