A steer-by-wire apparatus for rotating a steerable wheel includes a steering member axially movable relative to a vehicle to effect rotational movement of the steerable wheel. The ball nut assembly is coupled with the externally threaded portion of the steering member. The steering member axially moves in response to rotation of the ball nut assembly relative to the steering member. A first motor connected with the ball nut assembly is operable to effect rotation of the ball nut assembly relative to the steering member. The pinion is meshingly engaged with the steering member. The steering member moves axially in response to rotation of the pinion. A second motor connected with the pinion is operable to effect rotation of the pinion relative to the steering member.
一种用于使可转向车轮转动的线控转向设备包括转向构件,该转向构件可相对于车辆进行轴向移动以实现可转向车轮的转动运动。滚珠螺母组件与转向构件的带有外螺纹的部分连接。转向构件响应于滚珠螺母组件相对于转向构件的旋转而轴向地移动。与滚珠螺母组件连接的第一马达可操作以实现滚珠螺母组件相对于转向构件的旋转。小齿轮与转向构件啮合式接合。转向构件响应于小齿轮的旋转而轴向地移动。与小齿轮连接的第二马达可操作以实现小齿轮相对于转向构件的旋转。
