End surface gear part of drive half shaft of vehicle and vehicle equipped with end surface gear part

Abstract

The invention provides an end surface gear part of a drive half shaft of a vehicle and the vehicle equipped with the end surface gear part. The end surface gear part is used for being connected with awheel hub of the vehicle and comprises a gear part body and a protective sleeve, wherein one end of the gear part body is detachably connected to the wheel hub of the vehicle to improve the stabilityof connection between the drive half shaft and the wheel hub of the vehicle; one end of the protective sleeve is connected to the gear part body; and the other end of the protective sleeve is connected to a slip yoke part of the drive half shaft. According to the embodiment of the invention, the end surface gear part of the drive half shaft of the vehicle is connected and fixed to the wheel hub of the vehicle, so that the drive half shaft of the vehicle has the advantages of high torque capacity, high assembling efficiency, good centering performance and the like and the efficient torque output of the drive half shaft of the vehicle is ensured. In addition, the cooperation of the end surface gear part and the wheel hub of the vehicle avoids complicated circumferential clearance and axialclearance during the running process of the vehicle, so as to avoid impact, vibration and noise, to ensure the stable and reliable transmission of the vehicle, and to prolong the service life of the drive half shaft of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle accessory manufacturing, and more particularly, relates to an end face gear of a vehicle driving half shaft and a vehicle with the end face gear. Background technique [0002] At present, the driving half shaft assembly is one of the key components in the power transmission system of off-road vehicles. It is mainly used for the disconnected drive axle and the left and right steering knuckle belt brake assembly. It is used in the disconnected drive axle (hereinafter referred to as "" Drive axle") and the two driving wheel hubs are connected and transmit torque. The hub end generally uses a fixed joint, that is, one end of the fixed joint of the driving half shaft is connected to the inner side of the hub by a spline and fixed by a self-locking nut and a split spring to realize shaft to non-slip. The end of the main reducer of the drive axle generally uses a moving joint, that is, one end of the mo...

AI Technical Summary

Problems solved by technology

[0003] When the vehicle is under normal driving conditions, the moving joint of the driving half shaft cannot be pulled off excessively, nor can there be collision interference, so that the vehicle handling performance can be satisfied, but when the vehicle is driving under extreme off-road conditions, the driving Bridges and wheels jump repeatedly with extreme road conditions, which may easily lead to the actual length of the existing driving half-shaft structure under dynamic alternating loads being too long or too short, and the self-locking nut connecting the driving half-shaft and the hub is prone to failure, and failure occurs Afterwards, the inner bearing of the wheel hub appeared loose and abnormal noise, and the wheel shook, which eventually caused the driving half shaft to fall out, which directly affected the handling stability and driving safety of the vehicle.
