Problems solved by technology

[0002] At present, the clamping method of the brake in the bench test of the drum brake mainly adopts the part-level fixture modified by the half shaft and the hub bearing, and directly installs the brake base plate and the brake drum. Although the structure is simple, it is difficult to restore the brake to the real vehicle. After the brake is installed, the rigidity of the system also changes greatly, and the test results are not ideal

Abstract

The invention discloses a drive axle clamp for an automobile drum brake bench test. The drive axle clamp comprises a sliding table base; the supporting frame is mounted at the upper part of the sliding table base; the first stress balance assembly is installed on the front face of the supporting frame; the second stress balance assembly is installed on the back face of the supporting frame; the drive axle is located in the supporting frame, one end of the drive axle is connected with the first stress balance assembly, the other end of the drive axle is connected with the second stress balance assembly, and the drive axle is fixed; wherein the two ends of the drive axle are connected with the corresponding drum brakes, and the drive axle is used for fixing the drum brakes. The first stress balance assembly, the second stress balance assembly and the drive axle are loaded according to the real vehicle state, the real vehicle installation environment of the drum brake is restored, the real test condition can be reflected in the real vehicle stress mode, and the test result is ideal.

Description

technical field [0001] The present invention relates to the technical field of a jig for a brake bench test, in particular to a transaxle jig for an automobile drum brake bench test. Background technique [0002] At present, the clamping method of the brake in the drum brake bench test mainly adopts the part-level fixture modified from the half shaft and the hub bearing, and directly installs the brake base plate and the brake drum. Although the structure is simple, it is difficult to restore the brake to the actual vehicle. The rigidity of the system after the brake is installed is also greatly changed, and the test results are not ideal. SUMMARY OF THE INVENTION [0003] The purpose of the present application is to overcome the above-mentioned problems or at least partially solve or alleviate the above-mentioned problems. [0004] The technical solution of the present invention provides a drive axle fixture for an automobile drum brake bench test, comprising: a sliding ...
