The invention discloses a vehicle steering gear, a steering system and a vehicle. The vehicle steering gear comprises a lead screw, a movement assembly and an output shaft, the movement assembly comprises an inner shell and a roller, the inner shell is arranged around the periphery of the lead screw, the two axial ends of the lead screw penetrate out of the inner shell, and the roller is located between the inner circumferential wall of the inner shell and the outer circumferential wall of the lead screw; the two axial ends of the roller are rotationally connected with the inner shell respectively, the outer circumferential wall of the roller and the inner circumferential wall of the inner shell are spaced, the roller is in threaded fit with the lead screw, under the condition that the lead screw rotates, the roller rotates to drive the movement assembly to move in the axial direction of the lead screw, and the movement assembly moves to drive the output shaft to rotate. The vehicle steering gear is high in bearing capacity, capable of being used under the heavy load condition, simple in structure, convenient to machine and assemble, low in cost and convenient to use.

    本发明公开了一种车辆的转向器、转向系统和车辆,车辆的转向器包括丝杠、运动组件和输出轴,运动组件包括内壳和滚柱,内壳环绕在丝杠的外周设置且丝杠的轴向两端穿出内壳,滚柱位于内壳的内周壁与丝杠的外周壁之间,滚柱的轴向两端分别与内壳可转动地相连,滚柱的外周壁与内壳的内周壁之间间隔开,滚柱与丝杠螺纹配合,在丝杠转动的条件下,滚柱转动以带动运动组件在丝杠的轴向上移动,运动组件移动以驱动输出轴转动。根据本发明的车辆的转向器,承载能力高,可在重载情况下使用,而且结构简单,加工和装配都比较方便,成本较低,便于使用。
