The invention belongs to the field of automobile chassis steering systems, and provides a steering wheel transmission system with redundant power assistance in order to solve the technical problem that when a power steering device of an existing power steering system fails, a driver needs to independently undertake the automobile steering task, and operation difficulty or errors are prone to occurring. Comprising a first lead screw nut pair, a power-assisted driving assembly, a holder unit, a steering arm and a sensor, the output end of the power-assisted driving assembly is connected with one end of a first nut of the first lead screw nut pair, the other end of the first nut and the holder unit form a second lead screw nut pair, and outer teeth or racks are arranged on the outer side wall of the holder unit; the outer teeth or the rack is meshed with a gear installed on the steering arm, the gear and the steering arm are coaxially arranged, the steering arm is connected with an external steering connecting rod, a first lead screw of the first lead screw nut pair is connected with the steering device, the sensor is connected with the power-assisted driving assembly, and the detection end of the sensor faces the first lead screw and is used for detecting whether the first lead screw rotates or not.

    本发明属于汽车底盘转向系统领域,为解决现有动力转向系统在动力转向装置失效时,驾驶员需要独立承担汽车转向的任务,容易出现操作困难或出错的技术问题,提供一种带有冗余助力的方向盘传动系统,包括第一丝杠螺母副、助力驱动组件、保持架单元、转向臂和传感器,助力驱动组件的输出端与第一丝杠螺母副的第一螺母一端相连,第一螺母的另一端与保持架单元形成第二丝杠螺母副,保持架单元外侧壁上设有外齿或安装有齿条,外齿或齿条与转向臂上安装的齿轮相啮合,齿轮与转向臂同轴设置,转向臂与外部的转向连杆相连,第一丝杠螺母副的第一丝杠与转向装置相连,传感器与助力驱动组件相连,传感器的检测端朝向第一丝杠,用于检测第一丝杠是否转动。
