Abstract

The invention relates to an air bag air suspension rear axle for a passenger coach. The air bag air suspension rear axle comprises an axle body, two adapting seats, a thrust rod support, an axle housing, a brake chamber, an adjusting arm, a break chamber support, a joint bearing, a cam shaft, a shock absorber, a C-shaped girder, a thrust rod, an air bag, and a stabilizing rod. A left adapting seat and a right adapting seat are welded to a position, which is used for placing a plate spring originally, of a square section of the axle body. The stabilizing rod is connected with the adapting seats. The C-shaped girder is fixed onto the adapting seats through bolts. The thrust rod support is welded to the top of the axle housing in the middle of the axle body. The thrust rod is connected with the thrust rod support. The brake chamber support is disposed on the inner side of the C-shaped girder and is fixed to the axle housing in a welded manner. The cam shaft is connected with the brake chamber support through the joint bearing. The brake chamber is connected with the brake chamber support through the adjusting arm. Compared with the prior art, the air bag air suspension rear axle for the passenger coach is reasonable in layout, fine in performance, low in cost and the like.

Description

technical field [0001] The invention relates to a suspension system, in particular to an air bag air suspension rear axle for passenger cars. Background technique [0002] At present, the suspension of passenger cars mostly adopts leaf spring suspension, and the passenger car with leaf spring suspension has relatively poor riding comfort. Undoubtedly, the use of air suspension in passenger cars can greatly improve the ride comfort of high-grade passenger cars. However, the current air suspensions are all imported, the price is high, and the after-sales service is difficult, which has seriously affected the promotion and application of air suspensions on high-grade passenger cars. The key to developing the localized 6-airbag air suspension is how to install and fix the suspension on the axle body, including the fixing of the C-shaped beam and the axle body, and the connection between the thrust rod and the axle body. In particular, the C-shaped beam takes up a lot of space,...
