Description

Integrated single-hole test device for automobile steering knuckle

Technical Field

The utility model relates to a test device, in particular to an integrated single-hole test device for an automobile steering knuckle.

Background

Knuckle is an important structural component of an automotive chassis suspension system. In the direction of the vehicle outside, the knuckle is connected with a bearing, a brake disc and wheels, in the direction of the vehicle inside, according to different suspension forms, the knuckle can be connected with parts such as a shock absorption cylinder, a steering pull rod, a control arm and the like, and finally the whole suspension is connected and fixed on the vehicle body. The knuckle is subjected to sprung mass and also to loads transmitted by different road surface excitations. In the running process of the automobile, once the steering knuckle fails, serious safety accidents are caused. To verify its safety performance, bench test verification must be performed during the knuckle development phase. The single well test is the most common test among knuckle test protocols developed by existing host factories. The single bore type test requires restraining the wheel-connecting side of the knuckle, applying a load at each connecting bore.

The parts that knuckle is connected are different, and the loading direction of each connecting hole test is also different, and the test bench of every connecting hole is also different, and every test all needs to design frock alone and build the bench, this just causes test cycle extension, and test efficiency is low.
