The invention relates to a bogie for mounting a traction motor in a flexible suspending manner. Through the adoption of the bogie, the lateral movement force of a wheel track at high-speed running can be decreased to a certain extent; the smoothness of a vehicle can be improved; besides, the condition that the stress at the connecting part of a motor mounting seat and a crossbeam steel pipe is large can be improved; and the size and the weight of the bogie can be decreased. The motor adopts a four-point flexible suspending manner; 4 mounting holes are formed in the motor mounting seat on crossbeams; rubber nodes are mounted at the mounting holes; the rubber nodes are connected with the traction motor; a traction pull rod seat of a single traction pull rod is formed by the integrated extension of a side board of the motor mounting seat; the motor mounting seat is welded to the crossbeams in a curve joint manner, so that the stress is reduced; a vertical stop seat is arranged on the crossbeams, and the vertical stop seat and the motor mounting seat are integrally connected; side beams, the crossbeams, the motor and braking mounting seats are welded to form an integral structure; basic braking devices adopt a four-point suspending manner; tread cleaning devices are mounted on the braking mounting seats; and air spring seats are arranged on the side beams, air holes are formed in the side beams, and the crossbeams are used as an auxiliary air chamber.
Description
technical field [0001] The invention belongs to the field of vehicle bogies, in particular to a bogie for rail vehicles, especially for high-speed trains. Background technique [0002] It is found in the current use that when the design size of the motor is large, the space design structure of other parts of the bogie needs to be as compact as possible, and the design method of the motor mounting seat needs to be improved. From the strength simulation calculation and the measured data of the line operation, it is found that the stress at the connection between the motor mounting seat and the steel pipe of the beam is relatively large. [0003] In order to improve this situation, the installation method of elastic suspension of the traction motor can effectively improve the lateral stability of the vehicle, reduce the vibration acceleration of the motor, and to a certain extent reduce the lateral force of the wheel and rail during high-speed operation, and improve the stabili...
