Abstract

An embodiment of the present application provides a bogie for a rail vehicle and the rail vehicle. The bogie, the wheel set, the wheel set includes the axle and two wheels, the axle is the axle of the hollow shaft structure; the two wheel set axle boxes and the two axle boxes use bearings, the inner rings of the axle boxes are fixed on the axle shaft and It is located between two wheels; the wheel-to-axlebox is sleeved on the outer ring of the bearing for the axlebox; the permanent magnet direct drive motor is set between the two wheel-to-axleboxes, and the permanent magnet direct-drive motor includes a motor casing and a rotor , the stator and two motor end covers, the two motor end covers are fixed at both ends of the motor shell, the motor end cover has an end cover shaft hole; the rotor is fixed on the outer peripheral surface of the axle to directly drive the axle, the stator and the motor shell are fixed It is integrated and sleeved on the outside of the rotor. The rail vehicle comprises the bogie described above. The embodiment of the present application solves the technical problems of the existing motor direct drive bogie with complex structure and high mass.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a bogie for rail vehicles 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 set of the tra...
