High-speed train power closed loop hanging-type gearbox reliability test bench

Abstract

The invention discloses a high-speed train power closed loop hanging-type gearbox reliability test bench, so as to overcome the problem that a reliability test can not be carried out on the actually-operating train gearbox. The high-speed train power closed loop hanging-type gearbox reliability test bench comprises a rectangular bearing platform, a gantry vertical excitation device, a vertical hanging device, a vibration shaft device, a transverse excitation device and a motor torque force measurement device, wherein the gantry vertical excitation device is arranged at the rear end of the rectangular bearing platform; the vertical hanging device is arranged at the top end of the gantry vertical excitation device; the vibration shaft device is arranged in a first U-shaped groove and a second U-shaped groove of the vertical hanging device; the transverse excitation device is arranged in front of the gantry vertical excitation device; a two-force rod fork of the transverse excitation device is in rotary connection with a first shaft head assembly in the vibration shaft device; first counterforce supporting seats in four counterforce seat assemblies of the motor torque force measurement device are symmetrically arranged at the left side of the first U-shaped groove and the right side of the second U-shaped groove; and four force measurement sensors are in bolt connection with the first U-shaped groove and the second U-shaped groove.

Description

technical field [0001] The invention relates to a test platform for detecting parameters of a rail vehicle transmission system, more specifically, the invention relates to a reliability test platform for a high-speed train electric closed-loop suspended gearbox. Background technique [0002] At present, under the premise that our country implements the principle and policy of greatly increasing the speed of railways, the running speed of rail vehicles in our country has been greatly improved. This has also led to the rapid development of EMU technology. At present, the maximum speed of EMUs in operation has reached 350km / h, and the maximum speed of EMUs under development is close to 500km / h. However, with the increase of the train speed and the aggravation of the vehicle axle load, the vibration between the vehicle and the track is intensified, the running stability of the vehicle is reduced, and the problems of train safety and running stability are becoming more and more p...
