[0008] Chinese Patent Application Publication No. CN107839710 A discloses a bogie for a low-floor tram. The motors of the bogie are arranged longitudinally and have a relatively complicated structure. In addition, the patent application uses conical rubber springs for positioning, and the suspension method adopts the secondary suspension of conical rubber springs and rubber hourglass springs. The ability to pass through small curves and the shock absorption performance of the system are not high

Abstract

The invention discloses a tramcar and a bogie. The bogie includes a frame, a swing bolster and a wheel pair; the left and right ends of the frame are respectively provided with axle box beams, the axle box beams include axle box beam bodies and axle boxes located at the front and rear ends of the axle box beam bodies, and an axle end of the wheel pair is mounted in the corresponding axle box through an axle box positioning sleeve; the axle box beam bodies are installed under the longitudinal beam of the frame, the axle box beam bodies are connected with the end of the swing bolster through a vertical shock absorber, and the end of the swing bolster is mounted on the frame. The bogie effectively improves the small curve passing ability and the system damping performance of the tramcar.

Description

technical field [0001] The invention relates to a tram and a bogie, belonging to the field of rail transportation. Background technique [0002] Trams, especially low-floor trams, are one of the main tools of urban rail transit. Its main feature is that the vehicle floor height is lower than that of ordinary subway vehicles, which is convenient for passengers to get on and off. The low-floor tram bogies are used as low-floor vehicles The running part of the car is a key component to realize the low floor of the vehicle. [0003] In order to adapt to the low-floor floor of low-floor trams, the current mainstream method is to arrange the motors longitudinally on both sides of the bogie or use the wheel-side drive technology of independent wheel-set motors to make room for the inner side of the bogie wheel-set to realize Flooring of trams. However, low-floor trams use motors arranged longitudinally on the outside of the frame. This structure is relatively complex and the cost...
