Abstract

The invention relates to a brake bottom plate integrated axle housing assembly which comprises an axle housing and a brake bottom plate, a machining outer circle is arranged on the axle housing. The machining outer circle is annular limiting protrusions located at the two ends of the axle housing, a machining inner hole is formed in the brake bottom plate, the machining inner hole is located in the center of the brake bottom plate and can be matched with the machining outer circle, the machining outer circle sleeves the machining inner hole, and the two sides of the brake bottom plate and theaxle housing are connected into a whole through a welding process. A bearing limiting boss and a bearing inner hole are arranged on the brake bottom plate, a bearing is arranged close to the bearing limiting boss, a cam shaft support is inserted into the bearing inner hole, a cam shaft is arranged on the cam shaft support, and the cam shaft is inserted into a hole in the middle of the bearing. A supporting pin hole is further formed in the brake bottom plate, and a supporting pin is inserted into the supporting pin hole; the brake bottom plate and the axle housing are directly welded, parts such as fixing flange plates and connecting bolts are omitted, the structure is optimized, weight reduction of the axle is facilitated, and cost is saved.

Description

technical field [0001] The invention belongs to the field of vehicle axle design, and relates to an axle housing assembly matching a drum brake, in particular to an integrally welded axle housing assembly of a brake base plate and an axle housing for heavy trucks. Background technique [0002] The axle housing is the base for installing the main reducer, differential, half shaft and wheel assembly, and its main function is to support and protect the main reducer, differential and half shaft. The brake bottom plate is the supporting part for the assembly of the fixed brake shoe assembly and the brake drum in the automobile brake. It is the core of the vehicle brake. The brake bottom plate is installed on the fixed position of the axle. Equipped with brake shoes, return springs and positioning pins to withstand the rotational torque during braking. Most of the brake bottom plates are installed on the flanges of the middle and rear axle housings through bolts, and are detachab...
