Description

Technical field

[0001] The invention relates to a test device for axle box bearings and grounding devices of rail vehicles, and more specifically, the present invention relates to a comprehensive performance test bench for axle box bearings and grounding devices. Background technique

[0002] High-speed EMUs are one of the core technologies of high-speed railways. Axle box bearings and shaft end grounding devices are an important part of the EMU's driving process. In the actual operation of the EMU, the performance of the axle box bearings directly affects the operation of the EMU. If the axle box bearing is damaged, the rotation accuracy of the bearing will be lost, vibration will increase, noise and rotation resistance will be generated, and serious vehicle safety accidents will be caused. The performance of the shaft end grounding device directly affects the operation of the EMU, and the damage of the shaft end grounding device can cause fatal problems such as train power fail...
