Bogie for mounting traction motor in flexible suspending manner

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.
