The invention provides a rear wheel steering gear and a vehicle with the rear wheel steering gear. The rear wheel steering gear comprises a shell; the lead screw nut mechanism is used for converting the rotary motion of the output shaft of the driving motor into the axial linear motion of the lead screw main shaft from the lead screw nut; the ball bearing is arranged between the sleeve and the shell; the locking mechanism comprises a first locking assembly and a second locking assembly, the first locking assembly is connected with the end of the sleeve, the first locking assembly is used for providing axial pre-tightening force for the lead screw nut mechanism to eliminate the axis assembling gap of the lead screw nut mechanism, and part of the second locking assembly is connected with the end of the sleeve and used for providing axial pre-tightening force for the lead screw nut mechanism to eliminate the axis assembling gap of the lead screw nut mechanism. And the other part of the second locking assembly is connected with the shell, and the second locking assembly is used for limiting the motion freedom degrees of the two axial ends of the ball bearing. The problem that a rear wheel steering gear in the prior art is complex in structure is solved.
本发明提供了一种后轮转向器及具有其的车辆,后轮转向器包括:壳体;丝杆螺母机构,丝杆螺母机构用于将驱动电机的输出轴的旋转运动由丝杠螺母转化为丝杠主轴的轴线直线运动;球轴承,球轴承设置于套筒和壳体之间;锁止机构,锁止机构包括第一锁止组件和第二锁止组件,第一锁止组件与套筒的端部连接,第一锁止组件用于为丝杆螺母机构提供轴向的预紧力以消除丝杆螺母机构的轴线装配间隙,部分的第二锁止组件与套筒的端部连接,另一部分的第二锁止组件与壳体连接,第二锁止组件用于为球轴承的轴向两端的运动自由度提供限位。以解决现有技术中的后轮转向器的结构复杂的问题。
