Drive axle with wet brakes and sectional axle housings

Abstract

The invention relates to a drive axle with wet brakes and sectional axle housings. The drive axle comprises an intermediate axle housing, a differential assembly, a left semi-axle, a right semi-axle, a left axle housing, a right axle housing, a left wheel side speed reducer assembly, a right wheel side speed reducer assembly, a left wet brake and a right wet brake, wherein the differential assembly is embedded and mounted into the intermediate axle housing; the left axle housing and the right axle housing, as well as the left wheel side speed reducer assembly and the right wheel side speed reducer assembly are sequentially and symmetrically arranged on the left side and the right side of the intermediate axle housing from inside to outside; the left wet brake and the right wet brake are symmetrically arranged and respectively located on the inner side of a joint between the intermediate axle housing and the left axle housing and on the inner side of a joint between the intermediate axle housing and the right axle housing; one end of the left semi-axle is connected with the differential assembly, and the other end penetrates the left wet brake and the left axle housing sequentially, and is then connected with the left wheel side speed reducer assembly; one end of the right semi-axle is connected with the differential assembly, and the other end penetrates the right wet brake and the right axle housing sequentially, and is then connected with the right wheel side speed reducer assembly. The drive axle has the characteristics of being stable in brake performance, uniform in stress to paired friction parts, convenient to machine, low in rejection rate and the like.

Description

technical field [0001] The invention relates to the technical field of transmission systems of transport vehicles, in particular to a drive axle with wet brakes and segmented axle housings. Background technique [0002] At present, the commonly used drive axles generally adopt drum brakes. The drum brakes have a simple structure and low cost, but the drum brakes have the following disadvantages: 1. The brake shoe friction plate is easy to crack and ablate; 2. The brake sticks It is difficult to remove mud, water, oil, etc., which affects the stability of braking; 3. The braking area is small, resulting in unstable braking force and poor heat dissipation; 4. Most of the existing drive axles use integral cast axle housings or Welded axle housings have poor casting process, are not easy to process, and are prone to waste products. Contents of the invention [0003] The purpose of the present invention is to provide a drive axle with wet brake and segmented axle housing, ...
