Bench test tool for automobile multi-link suspension system

Abstract

The present invention provides a bench test tool for an automobile multi-link suspension system, belonging to the field of performance test equipment of automobile suspension systems. The test tool comprises a base component, wherein an auxiliary frame mounting bracket is connected to the base component, the lower end of the auxiliary frame mounting bracket is fixedly connected with a mounting point, a shock absorber mounting component is arranged on the auxiliary frame mounting bracket, a towing arm mounting seat and a loading component I for simulating the lateral force and the frictional resistance of a tire are arranged at the lower portion of the base component, and a loading component II for simulating the ground reaction force of the tire is arranged at the upper portion of the base component. The test bed achieves the suspension system that one set of test tool matches multiple specifications, clamping and location are performed according to the whole automobile gesture, multiple experiments can be performed in one-time clamping, the precision of a test result is higher, the tool universalization is achieved, the input of a special tool can be reduced, the test efficiency can be improved, and the test cost and the verification period can be reduced.

Description

technical field [0001] The invention relates to the field of performance testing equipment for an automobile suspension system, in particular to a bench test fixture for an automobile multi-link suspension system. Background technique [0002] The suspension system is mainly responsible for all force transmission connection devices between the car frame or load-bearing body and the axle or wheels, which transmits the force acting between the wheels and the frame and buffers the impact force transmitted from the uneven road to the body, reducing the Vibration is one of the important systems of the car to ensure the smooth running of the car. [0003] In order to ensure the reliability of the suspension system operation, lateral force tests, friction resistance tests, braking force tests, vertical force tests, etc. are usually carried out to check whether its fatigue durability meets the design requirements. At present, most chassis parts manufacturers use to test each compon...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a bench test fixture for an automobile multi-link suspension system, which mainly solves the problem that the traditional automobile suspension system fatigue durability test cannot integrally simulate the stress state of the car body during driving, The problems of long test period, low test result accuracy and high test cost are aimed at reflecting the actual working conditions to the greatest extent by assembling the multi-link suspension system on the test fixture according to the attitude of the whole vehicle. A certain range of loads are applied in the lateral, longitudinal, and vertical directions to carry out the durability test, which simulates the stress state of the car body during driving. One clamping can carry out tests in various working conditions, realizing universal tooling It reduces the investment of special tooling and improves the test efficiency, thereby reducing the test cost and verification cycle
