Rail vehicle axle end grounding device wear test bench

Abstract

The invention relates to a rail vehicle grounding drainage test apparatus, and more specifically relates to a rail vehicle shaft end grounding apparatus wear test bench. The test bench comprises a test equipment assembling body, a heat dissipation fan assembling body and a test apparatus protective cover assembling body, wherein the test apparatus protective cover assembling body is fixed above the test equipment assembling body; the heat dissipation fan assembling body is fixed above the test apparatus protective cover assembling body, the test equipment assembling body comprises two symmetrically arranged test shaft assembly and bearing pedestal assembling bodies and a motor and motor support column assembling body; and the motor and motor support column assembling body and the two test shaft assembly and bearing pedestal assembling bodies are respectively in transmission connection through driving belt assemblies. Through a double-test-shaft transmission test apparatus provided by the invention, the rotating speed and the current working condition of a motor train unit in an actual track can be accurately simulated, a quite good test foundation is provided for a loss test of a rail vehicle shaft end grounding apparatus, and the accuracy of test data is guaranteed.

Description

technical field [0001] The invention relates to a rail vehicle grounding drainage test device, more specifically, the invention relates to a rail vehicle axle end grounding device wear test bench. Background technique [0002] As the main artery of the national economy, the railway is an important symbol to measure a country's infrastructure level and transportation capacity. High-speed EMUs are one of the core technologies of high-speed railways. Under the premise of ensuring operational safety, in order to further improve the operation quality of my country's high-speed railways, it is imperative to improve the overall technical level of EMUs, and optimizing the shaft end grounding device of EMUs is one of them. very important technical issue. [0003] The grounding device is an important part of the EMU grounding system. Its main function is to prevent the current from passing through the EMU bearings to cause electric corrosion and endanger the driving safety. The high-...
