AI Technical Summary

Technical Problem

Existing test benches for axle steering mechanisms cannot comprehensively simulate the complex and combined working conditions on real roads, including vertical loads, steering actions, ground friction, centrifugal force, and slope attitude. This results in test results that are out of sync with those of real vehicles, making it impossible to effectively evaluate their performance and durability.

Method used

Design a comprehensive test device integrating a vertical loading module, a steering drive module, a torque loading module, a lateral force loading module, and a longitudinal tilt angle loading module. Through multi-axis linkage, simulate the actual forces on a vehicle when turning or going uphill or downhill, and achieve coordinated loading and precise control of various factors.

Benefits of technology

It effectively simulates the stress state of vehicles under complex working conditions, improves the efficiency and convenience of performance and durability testing, and fills a gap in the industry.

Abstract

The invention relates to an axle steering mechanism testing device, and the device comprises a to-be-tested axle vertical loading module which is disposed on a to-be-tested axle and is used for applying a vertical load to the to-be-tested axle; the output end of the steering driving module is connected with a steering knuckle arm of the axle to be tested, and the steering driving module is used for driving the axle to be tested to perform steering action; the torque loading modules are correspondingly connected to two wheel edge output ends of the axle to be tested respectively, and each torque loading module comprises a universal connection unit used for providing multi-degree-of-freedom constraint; and a torque loading unit. According to the invention, a highly integrated and multi-axis linkage comprehensive test bench is innovatively constructed, the modules cooperate with each other to effectively simulate the actual stress of an axle when a vehicle turns or goes uphill and downhill during testing, and the problems that an existing test bench is single in function and cannot simulate composite working conditions are effectively solved. The efficiency and convenience of performance and durability testing are improved, and the industry blank is filled.
