Abstract

The invention discloses an electric open-loop hanging transmission system reliability test bench. In order to overcome the problem that the EMU transmission system reliability test cannot be performed during the actual operation of the EMU, it includes a transmission system vertical vibration device, Transverse vibration excitation device for transmission system, suspension support device, gearbox power open-loop suspension vibration excitation assembly, torque detection test device and installation platform. The vertical vibration excitation device of the transmission system is located on the right side of the installation platform; the suspension support device is installed on the vertical vibration excitation device of the transmission system. On the hanging basket in the hanging support device, two U-shaped seats are installed on the left and right sides of the simulated high-speed train transmission system assembly, and the drive motor and drive train transverse vibration device are located on the left side of the installation platform. The dynamometer is installed on the foundation; the torque detection test device is installed on the installation platforms at the front and rear sides of the simulated high-speed train transmission system assembly.

Description

technical field

[0001] The invention relates to a test platform for detecting parameters of a rail vehicle transmission system, more precisely, the invention relates to a reliability test platform for an electric open-loop suspended transmission system. Background technique

[0002] At present, my country's EMU technology is developing rapidly. The maximum speed of the EMUs in operation has reached 350km / h, and the maximum speed of the newly developed EMUs is close to 600km / h. With the increase of train speed and the increase of vehicle axle load, the vibration between the wheel and the track is intensified, the running stability of the vehicle is reduced, and the safety and ride comfort of the train are becoming more and more prominent. At the same time, with the on-line operation of a large number of high-speed EMUs, the maintenance work of EMUs at all levels is also carried out. Among them, the maintenance of the transmission system is an important part of the maintenance...
