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.
轨道交通车辆用无车桥主动转向独立轮定位装置属于特种轨道车辆用独立轮定位装置领域,其包括:左车轮安装法兰、右车轮安装法兰、左车轮驱动器、右车轮驱动器、左车轮转动主轴、右车轮转动主轴、左车轮定位中间体、右车轮定位中间体、左车轮A字形上拉杆、右车轮A字形上拉杆、左车轮A字形下拉杆、右车轮A字形下拉杆、转向作动器、转向机构、抗侧滚扭杆、空气弹簧和可控阻尼减振器。本发明允许凹字形的列车地板上的中心部分从该间隙之间贯穿通过,并取缔列车地板上的斜坡和台阶结构设计,进而实现列车的全列100%低地板化。
