The present disclosure provides a rotation assist apparatus for a recirculating ball steering gear. An exemplary motor vehicle steering system includes an input shaft coupled to a steering shaft of a motor vehicle; the first end of the worm gear is connected to the input shaft, and the second end of the worm gear is fixed to a helical spur gear; a ball nut surrounding a portion of the worm wheel, the ball nut including a ball bearing and a ball guide; an intermediate gear fixed to a first pinion gear, the first pinion gear being engaged with the helical spur gear; a motor fixed to a second pinion, the second pinion engaged with the intermediate gear, the motor for rotating the worm gear to translate the ball nut; and a sector gear engaged with the ball nut, the sector gear rotating as the ball nut translates.

    本公开提供了“用于循环球式转向齿轮的旋转辅助设备”。示例性机动车辆转向系统包括:输入轴,所述输入轴联接到机动车辆的转向轴;蜗轮,所述蜗轮的第一端联接到所述输入轴,所述蜗轮的第二端固定到斜齿正齿轮;滚珠螺母,所述滚珠螺母围绕所述蜗轮的一部分,所述滚珠螺母包括滚珠轴承和滚珠引导件;中间齿轮,所述中间齿轮固定到第一小齿轮,所述第一小齿轮与所述斜齿正齿轮接合;马达,所述马达固定到第二小齿轮,所述第二小齿轮与所述中间齿轮接合,所述马达用于使所述蜗轮旋转以使所述滚珠螺母平移;以及扇形齿轮,所述扇形齿轮与所述滚珠螺母接合,所述扇形齿轮随着所述滚珠螺母平移而旋转。
