Abstract

The invention discLoses a drive axLe rear axLe appLicabLe to heavy trucks. The drive axLe rear axLe comprises an axLe body, an axLe sheLL, semi-shafts, brake assembLies, hubs, fixed bLocks, air chambers and a reducer assembLy, and is characterized in that an upper pLate spring seat and a Lower pLate spring seat are respectiveLy arranged at the two ends of the axLe body, the axLe sheLL is arrangedin the middLe of the axLe body, and the semi-shafts are respectiveLy arranged at the two ends of the axLe body; the brake assembLies are arranged on the semi-shafts, the hubs are arranged on the semi-shafts through connecting boLts, and the fixed bLocks are arranged on the axLe sheLL; connecting arms and connecting bLocks are arranged on the fixed bLocks, the air chambers are connected with connecting arms through connecting shafts, and the reducer assembLy is arranged on the axLe sheLL. The connecting bLocks are connected with the brake assembLies through connecting pipes, the connecting strength between the connecting bLocks and the brake assembLies is improved, air in the air chambers can be convenientLy conveyed to the brake assembLies, and the work efficiency of the brake assembLies is increased.

Description

technical field [0001] The invention relates to the technical field of heavy-duty trucks, in particular to a drive axle rear axle suitable for heavy-duty trucks. Background technique [0002] With the development of high-grade road transportation in our country, the requirements for road vehicles have also changed, and heavy-duty trucks are used more and more widely. The demand for drive axles and rear axles of heavy-duty trucks is also increasing. The existing drive axles and rear axles of heavy-duty trucks have heavy weight, a large number of parts, and high manufacturing costs, which increases the cost of heavy-duty trucks. The burden shortens the service life of the rear axle of the drive axle. Contents of the invention [0003] The purpose of the present invention is to provide a reasonable structure design, good quality and performance, light weight, parts The utility model relates to a drive axle rear axle suitable for heavy-duty trucks with small quantity, low ma...
