Abstract

The embodiment of the present application provides a motor end cover for a bogie, a bogie and a rail vehicle. The motor end cover has a through end cover shaft hole, and the end cover shaft hole is used for the axle of the bogie to pass through; the outer side of the motor end cover has a motor end cover flange, and the motor end cover is turned over There are bolt holes on the side of the motor end cover, and the bolt holes of the motor end cover are used to fix the wheel-to-axle box of the bogie; the inner side of the motor end cover is used to connect with the permanent magnet direct drive motor of the bogie The motor housing is fixed. The bogie includes the aforementioned motor end cover. The rail vehicle comprises the bogie described above. The embodiment of the present application provides to solve the technical problem that the existing motor direct-drive bogie needs to provide a separate support structure for the permanent magnet direct-drive motor, resulting in complex structure and high mass of the bogie.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a motor end cover for a bogie, a bogie and a rail vehicle. Background technique [0002] The traditional bogie drive system adds a transmission gearbox and a coupling on the basis of the traction motor. The gear meshing friction pairs and gear couplings of the gear transmission will generate different degrees of noise and vibration during the meshing process; the transmission process It will also cause power loss and reduce efficiency; in addition, the gear meshing friction pair will gradually wear out, and maintenance and replacement will increase the operation and maintenance costs, etc., which also lead to a large quality of the bogie. [0003] The motor direct drive bogie refers to the bogie that directly transmits the output torque or force of the traction motor to the wheel set by removing the transmission parts between the motor and the wheel s...
