Problems solved by technology

However, the drive axle is under axle load during actual use, which causes the axle housing to deform to a certain extent, and the supporting parts on the axle housing will be affected
Therefore, the current drive axle assembly bench test device cannot examine the drive axle with axle load and its accessories.

Abstract

The invention discloses a bench test device for a drive axle assembly with an axle load, and the device comprises a drive mechanism connected with the input end of a to-be-detected drive axle, a loading mechanism which is connected with two output ends of the to-be-detected drive axle, and an axle case loading mechanism for applying a load to the case of the to-be-detected drive axle. The axle case loading mechanism comprises a press plate assembly which is used for compressing the case of the to-be-detected drive axle, an axle case loading apparatus which is used for applying a load to the press plate assembly, and a sensor which is used for detecting the applied load of the axle case loading apparatus. According to the invention, the device irons out the defects of a bench test carried by a bench test device for a drive axle assembly under the no-load condition in the prior art. The device can simulate the operation condition of a real car with the drive axle with the load, and achieves a purpose of checking the drive axle and the accessories thereof.

Description

technical field [0001] The invention relates to a drive axle assembly bench test device. Background technique [0002] At present, when the drive axle assembly is installed on the bench test, the drive axle is usually fixed on the iron floor through the bracket at the position of the leaf spring seat, which does not match the state of the actual vehicle. [0003] At present, the drive axle assembly bench test devices are all bench tests without axle load. However, the drive axle is under axle load during actual use, which causes the axle housing to deform to a certain extent, and the supporting parts on the axle housing will be affected. Therefore, the current drive axle assembly bench test device cannot examine the drive axle with axle load and its accessories. Contents of the invention [0004] In order to overcome the shortcoming of carrying out the bench test under the condition of no axle load in the drive axle assembly bench test device in the prior art, the presen...
