Abstract

The invention discloses a vehicle steering system impact test device and a vehicle steering system impact test method. The test device comprises a torsion inertia weight, a steering column body, a steering machine body, a fixing bracket, a mounting base, a guide mechanism, a pendulum system, and a sensing display device. The test method comprises the steps of starting the pendulum system to make the pendulum system swing and apply force to the guide mechanism to enable the guide mechanism to move and drive one end of the steering machine body inside the guide mechanism to move together, and recording and storing the impact on the steering machine body through the sensing display device on the steering machine body. The test device provided by the invention has the characteristics of simple structure, low cost and obvious actual production advantage. The test method provided by the invention has the advantages of convenient and flexible operation and high efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to an impact test device and method for a vehicle steering system. Background technique [0002] The car steering system is a device used to maintain or change the driving direction of the car. When the impact and the car accidentally deviate from the driving direction, it can cooperate with the driving system to keep the car running stably. Therefore, the performance of the car steering system directly affects the maneuverability and safety of the car. In actual production, it is necessary to optimize the performance of the car steering system. carry out testing. [0003] In the prior art, the traditional impact test rig is generally used for simulation testing, and the traditional impact test rig generally uses a hydraulic servo cylinder, and the hydraulic servo cylinder is used for loading tests to obtain test results; however, the existing hydraulic servo cylinder ...
