Description

Technical Field

[0001] The utility model relates to the technical field of rear axle housing processing, in particular to a clamp for an automobile rear axle housing. Background Art

[0002] The front axle and rear axle refer to the front and rear wheel axles. The front axle includes shock absorber springs, steering gears, balance shafts, etc., and the rear axle also includes drive shafts, transmission gears, etc. The rear part of a multi-axle truck is also divided into a drive rear axle and a non-drive rear axle. The non-drive rear axle is the part that is not connected to the drive shaft and does not belong to the drive wheel. It is generally only available for heavy trucks and tractor heads with more than 3 axles. The rear axle refers to the rear drive shaft component of the vehicle power transmission. It consists of two half-bridges and can implement half-bridge differential movement. At the same time, it is also a device for supporting the wheels and connecting the rear wheels. If it is a front-axle driven vehicle, the rear axle is only a follower axle and only plays a bearing role. The bridge housing is the base for installing the main reducer, differential, half-axle, and wheel assembly. Its main function is to support and protect the main reducer, differential, and half-axle. Generally speaking, the axle housing of an ordinary non-disconnecting drive axle is a rigid hollow beam supported on the left and right drive wheels. The main reducer, differential, half-axles and other transmission parts are installed in it. The axle housing is connected to the frame or carriage through longitudinal leaf springs.
