Problems solved by technology

However, the suspension adopts rigid suspension, and the permanent magnet motor suspension is not decoupled, so the vibration during operation will have an excessive impact on the permanent magnet motor
[0008] In addition, the existing permanent magnet direct drive bogie has a high traction point, which is not suitable for high-speed locomotives under the condition of high power and large traction force

Abstract

The invention discloses a permanent magnetic direct drive bogie. The permanent magnetic direct drive bogie comprises a framework, a wheel set and a permanent magnetic motor. A hollow shaft is mountedon an axle of the wheel set in a sleeving mode, wherein a force transferring seat is fixedly arranged on the axle, the permanent magnetic motor is mounted on the hollow shaft in a sleeving mode, one end of the hollow shaft is connected with the permanent magnetic motor through a flexible coupling in a binding mode, and the other end of the hollow shaft is connected with the force transferring seatthrough the flexible coupling in a binding mode. Protrusions are arranged on two sides of a beam in the longitudinal direction. The permanent magnetic motor is flexibly connected with the framework through a swing rod and a hanger rod, wherein one end of the swing rod hangs on the protrusions, the other end of the swing rod is connected to a permanent magnetic motor shell, and the axial directionof the swing rod is arranged longitudinally. One end of the hanger rod is connected with the permanent magnetic motor shell, the other end of the hanger rod hangs on an end beam, and the permanent magnetic motor can move horizontally. Through the structural shape of the framework is improved, a hanging structure of the permanent magnetic motor is cooperated, the coordinated application of frame hang installation, low traction and a coupling, and the permanent magnetic motor as a power source to drive high-speed locomotive becomes possible.

Description

technical field [0001] The invention belongs to the field of rail vehicles, and in particular relates to a permanent magnet direct drive bogie and a rail vehicle thereof. Background technique [0002] At present, the high-speed locomotives at home and abroad all adopt the drive system with gear transmission, which has the problems of complex structure, large transmission loss and low reliability, especially the problem of lubrication and sealing during high-speed operation is difficult to solve. At the same time, there are also problems such as high noise and high maintenance costs. [0003] With the advancement of permanent magnet motor technology, the application of direct drive in rail vehicles is also increasing. At present, permanent magnet direct drive is mainly used in light rail vehicles with independent rotating wheels. The main form is wheel hub direct drive or wheel edge direct drive, both of which are directly driven by permanent magnet motors to rotate the whee...
