The invention relates to a steering gear and a power-assisted steering system. The power assisting device comprises a shell, a transmission structure, a moving structure and a power assisting structure, and a mounting cavity is formed in the shell; the transmission structure is arranged on the shell in a blocking mode in the first direction and extends to the installation cavity. The transmission structure is connected with the steering wheel assembly. The moving structure is movably arranged in the mounting cavity and connected with the front axle assembly and the transmission structure, and the moving structure can move in the first direction under the driving of the transmission structure; the power assisting structure is arranged in the mounting cavity and is in signal linkage with the steering wheel assembly, and when the steering wheel assembly rotates and sends a steering signal, the power assisting structure receives the steering signal and then drives the moving structure to move in the first direction together with the transmission structure. The power assisting structure and the transmission structure are matched with each other, and the power assisting structure conducts power assisting driving on the moving structure. The power assisting structure is in signal connection with the steering wheel assembly, when the vehicle does not steer, the power assisting structure does not operate, the load on a vehicle battery can be effectively reduced, and the influence of a steering system on the endurance mileage is reduced.

    本申请涉及一种转向器及转向助力系统。其包括壳体、传动结构、移动结构和助力结构,壳体内置有安装腔;传动结构沿第一方向堵设于壳体并延伸至安装腔,传动结构连接方向盘总成;移动结构活动设于安装腔并连接前轴总成和传动结构,移动结构在传动结构驱使下能够沿第一方向移动;助力结构设于安装腔,助力结构与方向盘总成信号联动,方向盘总成转动并发出转向信号时,助力结构接收转向信号后与传动结构共同驱使移动结构沿第一方向移动。本申请的助力结构与传动结构相互配合,助力结构对移动结构进行助力驱动。助力结构与方向盘总成信号连接,车辆不转向时,助力结构也不运转,能够有效减小对车辆电池的负荷,降低转向系统对续航里程的影响。
