Embodiment Construction

[0050] The present invention is described in detail below in conjunction with accompanying drawing:

[0051] The purpose of the present invention is to provide an electric open-loop suspension type transmission system reliability test bench, which solves the problem that it is difficult to carry out the transmission system reliability test in the actual operation of the existing trains, so as to meet the needs of rail vehicle transmission systems in various operating conditions. The next reliability parameter detection needs. The drive train vertical vibration device and the drive train transverse vibration device included in the test bench can accurately simulate the radial and axial loads on the drive system in actual working conditions and the high-speed EMU running on the actual line. Vibration conditions can truly reproduce the vibrations experienced by the transmission system of rail vehicles during operation, thus ensuring the correctness and authenticity of the test re...

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...
