Problems solved by technology

Because the whole vehicle suspension test system is relatively complex, expensive, and only for one type of suspension, it is impossible to improve the suspension on the test bench, and a quarter of the vehicle suspension can partially reflect the main characteristics of the suspension. Performance, in order to simplify the test equipment and reduce the test cost, the quarter car suspension test bench is an important means to study the suspension characteristics
[0003] At present, the quarter suspension test system at home and abroad is generally developed for a specific suspension form, that is, it can only be tested for a specific suspension form, and the versatility is poor; The point position is usually difficult to adjust, and it is impossible to test suspensions with different hard point positions; some test benches can adjust the degree of freedom in certain directions, but usually there are steps to adjust, and it is impossible to realize stepless adjustment in all directions , it is impossible to improve and optimize the suspension directly through the bench test

Abstract

The invention relates to a hard point position stepless adjusting type test rig satisfying multiple suspension fork types. The test rig comprises a suspension fork hard point position adjusting mechanism, a supporting frame (9) and a tire suspension fork system loading mechanism. The suspension fork hard point position adjusting mechanism is arranged in the supporting frame, and a cover plate (7) is arranged on the supporting frame (9). The tire suspension fork system loading mechanism is arranged on the cover plate (7). Compared with the prior art, the test rig has the advantages of being simple in structure, compact in layout, suitable for multiple suspension fork types, capable of satisfying the test of the multiple suspension fork types with the hard points smaller than four in number, and also capable of being applied to the suspension fork test with different hard point positions.

Description

technical field [0001] The invention relates to a suspension test bench, in particular to a hard point position stepless adjustable test bench that satisfies various suspension forms. Background technique [0002] In recent years, with the development of the automobile industry, people have higher and higher requirements for the ride comfort of automobiles, which requires automobile companies and scientific research institutions to continuously improve and develop suspension systems with superior performance. Because the whole vehicle suspension test system is relatively complex, expensive, and only for one type of suspension, it is impossible to improve the suspension on the test bench, and a quarter of the vehicle suspension can partially reflect the main characteristics of the suspension. Performance, in order to simplify the test equipment and reduce the test cost, the quarter car suspension test bench is an important means to study the suspension characteristics. [00...
