The invention discloses a rail transit vehicle and a steering device thereof, wherein the steering device comprises a first steering knuckle, a second steering knuckle, a first hydraulic steering structure, a second hydraulic steering structure and a controller; the first steering knuckle and the second steering knuckle are each arranged on an axle; the first hydraulic steering structure is connected with the first steering knuckle and drives the first steering knuckle to rotate so as to enable wheels on the axle to deflect; the second hydraulic steering structure is connected with the second steering knuckle and drives the second steering knuckle to rotate so as to enable the wheels on the axle to deflect; and the controller is in communication connection with the first hydraulic steering structure and the second hydraulic steering structure, and the controller responds to the failure of the first hydraulic steering structure or the second hydraulic steering structure which is independently started currently and switches to start the other hydraulic steering structure. Redundant design is adopted, and the problem that steering is out of control due to failure of steering structures such as an electric booster pump is effectively solved, so that the driving safety of the vehicle is effectively guaranteed, and the reliability of the rail transit vehicle is improved.
本发明公开了一种轨道交通车辆及其转向装置,转向装置包括:第一转向节及第二转向节,分别设置于车桥上;第一液压转向结构,与第一转向节连接,并且驱动第一转向节转动,以使车桥上的车轮进行偏转;第二液压转向结构,与第二转向节连接,并且驱动第二转向节转动,以使车桥上的车轮进行偏转;控制器,分别与第一液压转向结构及第二液压转向结构通信连接,控制器响应于当前独立启用的第一液压转向结构或第二液压转向结构失效,切换启用另一液压转向结构。本发明采用冗余设计,有效地解决了由电动助力泵等转向结构失效而导致的转向失控问题,从而有效地保证了车辆的行车安全,进而提升了轨道交通车辆的可靠性。
