Abstract

The invention discloses a performance test control system for an automobile steering system, comprising a steering stimulation device control, a road condition stimulation loading device control, a linear displacement sensor arranged on racks of a steering device and a computer monitoring system. The performance test control system for the automobile steering system can simulate the real road condition, measure parameters of kinesiology and mechanics in the automobile steering system such as input shaft full rotary angle of the steering system, transmission ratio characteristics, transmission clearance characteristics, transmission efficiency characteristics, rotating moment, rigidity tests, vertical jumping, steering angles under the working state of driving and the like.

Description

Technical field [0001] The invention relates to an automobile test control system, in particular to an automobile steering system performance test control system. technical background [0002] The automobile steering system needs to ensure that the automobile steers or maintains driving stability according to the driver's will, and its performance directly affects the safety and maneuverability of the automobile. Therefore, the performance test of automobile steering system is a necessary means for steering system research and development, performance verification and quality control, and is a key test to ensure the quality of steering gear products. The existing steering gear assembly test bench is a three-axis product test. During the test, the steering system of the automobile and the actual road conditions cannot be simulated, and the parameters cannot be tested under vehicle loading conditions. In particular, the vertical movement of the suspension will have a very importan...
