Description

Technical Field

[0001] The utility model relates to the technical field of height valve detection, in particular to a durability detection mechanism. Background Art

[0002] The vehicle height valve, also known as the height control valve, is used in vehicle suspension systems with air springs (airbags). It dynamically senses changes in vehicle height and promptly completes air intake or exhaust to adjust the height of the air spring (airbag) and improve driver comfort.

[0003] The durability test of the height valve is an extremely important step to test its performance. Since the working principle of the height valve is through a toggle control rod, the control rod is initially in the center position, and the control rod is driven to deflect by the external force, and the deflection of the control rod can make the valve body control the airbag inlet or outlet. For example, a height valve detection device is disclosed in the existing patent library, and its patent publication number is CN207622990U. In the detection device, one end of the control rod of the height valve is connected to the cylinder, and the cylinder output shaft pushes and pulls the control rod back and forth to test the limit of the number of times the control rod of the height valve deflects;

[0004] However, the control rod of the height valve is required to be offset hundreds of thousands of times. To ensure detection efficiency, the cylinder needs to perform relatively high-speed extension and retraction movements. The faster the extension and retraction speed of the cylinder, the higher the required air pressure. The relatively high air pressure will cause premature wear of the cylinder, greatly reducing its service life. Utility Model Content
