Abstract

The invention relates a test device of railway vehicle braking examine and repair technology, in particular to a round spring test device capable of testing performances of round springs such as axle-box spring and swing-bolster spring. The round spring test device comprises a base, a centering component, a support, a hydraulic system component, a main hydraulic cylinder and a top bar. The centering component is fixedly mounted on the base, the support and the hydraulic system component are fixedly mounted on one side of the base, the top bar is fixed on the support, the main hydraulic cylinder is fixed on the top bar, a displacement sensor is mounted on the main hydraulic cylinder, and a force sensor is mounted between the base and the centering component. The round spring test device is mainly used for testing the performances of the axle-box spring and the swing-bolster spring.

Description

Technical field [0001] The invention relates to a testing device for railway vehicle brake maintenance technology, in particular to a round spring testing device capable of testing the performance of round springs such as axle boxes and bolster springs. Background technique [0002] Railway spring axle box springs and bolster springs are important components that support and transmit the sprung mass of the vehicle, reduce the additional load caused by vehicle vibration, reduce the impact between various parts of the vehicle, between the vehicle and the line, and optimize the quality of vehicle operation. At present, there is no suitable test equipment that can accurately test the performance of all types of axle boxes and bolster springs. Summary of the invention [0003] The purpose of the present invention is to accurately detect the performance of round springs such as axle boxes and bolster springs, and to provide a round spring testing device capable of detecting the performa...
