Durability testing platform of automobile air brake manual controlling valve

Abstract

The invention provides a durability testing platform of automobile air brake manual controlling valve. The durability testing platform of automobile air brake manual controlling valve comprises a simulated movement machinery loading part and a pneumatic part driving the simulated movement machinery loading part. The machinery loading part comprises a support part, a sample fixing part, a handle swing arm and a swing arm driving part. The support part comprises a base plate. A standing plate perpendicular to the base plate is arranged on one side of the base plate. A straight line opening is arranged in the middle of the standing plate. A slide block slide is arranged on the upper half portion of the straight line opening. One side of the standing plate is connected with a sample fixing block. The swing arm driving part comprises straight line driving and swinging driving. A straight line driving air cylinder is installed on the base plate and is arranged in the straight line opening of the standing plate. A cylinder rod of the straight line driving air cylinder is connected with a sliding block. The sliding block is arranged in the slide. The handle swing arm is arranged on the upper portion of the riser. Two side arms at the lower end of the handle swing arm cross the upper end of the riser and are connected with the sliding block in a hinged mode through a shaft pin. The bottom of the swinging air cylinder is connected with the other side of the base plate through a lower hinged base. The cylinder rod of the swinging air cylinder is connected with an upper hinge base at the upper end of the handle swing arm in a hinged mode through a connecting fork. A handle claw is arranged at the upper end of the handle swing arm.

Description

technical field [0001] The invention relates to a durability test bench for an automobile air brake manual valve, which belongs to the technical field of durability detection and testing of automobile parts, in particular to a test bench for testing the durability of an automobile air brake manual valve assembly. Background technique [0002] The manual valve is an important part used to control the parking brake and emergency brake of the car. While the performance meets the design requirements, the durability is also very important. At present, the performance of manual control valves is mainly tested on the valve comprehensive test bench (or on a temporary simple bench). Since there is no special test bench, the handle of the manual control valve needs to be removed The test cannot completely simulate the working conditions of the real vehicle, which affects the authenticity of the test results. In many cases, the durability problem of the manual control valve needs to be...

Problems solved by technology

At present, the performance of manual control valves is mainly tested on the valve comprehensive test bench (or on a temporary simple bench). Since there is no special test bench, the handle of the manual control valve needs to be removed The test cannot completely simulate the working conditions of the real vehicle, which affects the authenticity of the test results. In many cases, the durability problem of the manual control valve needs to be exposed during the vehicle test or the process of using the vehicle, which reduces the development cost. increase, the development cycle is greatly lengthened
