Abstract

The invention discloses an automobile hydraulic jack endurance test device and a test method thereof. The device comprises a workbench, a hydraulic jack arranged on the workbench, a loading air cylinder arranged above the workbench and used for loading the hydraulic jack, and a driving unit and a decompression unit arranged on the workbench. The automobile hydraulic jack endurance test device has the advantages that the structure is simple, the installation and the disassembly are convenient, the cost is low and the working intensity of a tester is lowered. According to the test method, the real vehicle environment can be simulated to perform the automobile hydraulic jack endurance test, the influence of other parts on the test result is eliminated and the test data is more precise. The analysis method of the automobile hydraulic jack endurance can be verified and the reliable basis is provided for the innovative design of the automobile hydraulic jack.

Description

technical field [0001] The invention relates to an automobile hydraulic jack durability test device and a test method thereof, belonging to the technical field of automobile parts testing. Background technique [0002] According to the applicant's understanding, a car will be equipped with many commonly used on-board tools, among which the hydraulic jack is a relatively important tool. It is often encountered that some cars need to change tires or initially check the condition of the vehicle chassis. Move or lift the car without the front case of the equipment. The advantages of automotive hydraulic jacks are fast lifting speed, small size, long service life, easy manipulation and control, and greater load-bearing capacity than rack jacks. With the rapid development of my country's automobile industry, automobiles have higher and higher requirements for jacks, and the needs of users are constantly changing. The design quality of jacks must be continuously improved to meet t...
