Abstract

The invention discloses an axle-free active steering independent wheel positioning device for a rail transit vehicle, and belongs to the field of independent wheel positioning devices for special rail vehicles. The device comprises a left wheel mounting flange, a right wheel mounting flange, a left wheel driver, a right wheel driver, a left wheel rotating main shaft, a right wheel rotating main shaft, a left wheel positioning middle body, a right wheel positioning middle body, a left wheel A-shaped upper pull rod, a right wheel A-shaped upper pull rod, a left wheel A-shaped lower pull rod, a right wheel A-shaped lower pull rod, a steering actuator, a steering mechanism, an anti-side-rolling torsion bar, an air spring and a controllable damping shock absorber. According to the invention, the central part on the U-shaped train floor is allowed to pass through the gap, and the structural design of slopes and steps on the train floor is canceled, so that the 100% low floor of the whole train is realized.

Description

technical field [0001] The invention belongs to the field of independent wheel alignment devices for special rail vehicles, in particular to an axleless active steering independent wheel alignment device for rail transit vehicles. Background technique [0002] Existing urban rail transit vehicles are commonly called trams, which usually refer to a class of train-type electric urban rail transit vehicles that adopt a special rail line structure for load-bearing and travel guidance. At present, the mainstream urban rail transit vehicles are low-floor trams. Although the bogies of such low-floor trams have greatly reduced the height of the longitudinal structure near the center line, their wheel alignment devices still follow the belt structure of high-speed bullet train bogies. Axle wheelsets may be changed to independent wheelsets with axles. However, no matter which kind of wheel alignment device is used, the wheels positioned by it do not have the active steering or passiv...
