The invention discloses an electrically-driven steering system suitable for a forklift. The electrically-driven steering system comprises an axle housing, and a steering executing mechanism is installed in the axle housing in a matched mode. The axle housing, the connecting rods, the steering knuckle arms and the hubs form the steering axle assembly, and the steering executing mechanism, the motor, the controller and the like form an electric power assisting system to provide assisting power for the steering axle assembly; on one hand, the electric power assisting system is fixed to the axle housing through bolts and connected with the connecting rod, the motor directly provides assisting power for the steering executing mechanism, namely the ball screw, and torque of the motor is converted into pushing force in the determined direction; the motor is fixed on the axle housing and is responsible for providing a power source; the ball screw is responsible for converting rotating force of the motor into pushing force in a determined direction; when the steering axle assembly and the electric power assisting system work, noise is low, comfort is improved, and the steering axle assembly and the electric power assisting system are designed in a modularized mode and are suitable for different vehicle types.

    本发明公开了一种适用于叉车使用的电驱动转向系统,包括桥壳,所述桥壳内匹配安装转向执行机构。本发明通过桥壳、连杆、转向节臂以及轮毂组成了转向桥总成,转向执行机构、电机、控制器等组成了电动助力系统,为转向桥总成提供助力;电动助力系统一方面通过螺栓固定在桥壳上,并与连杆连接,电机直接为转向执行机构即滚珠丝杠提供助力,将电机的扭矩转换为确定方向的推动力;电机固定在桥壳上并负责提供动力源,滚珠丝杠负责将电机的旋转力转换为确定方向的推动力;转向桥总成和电动助力系统工作时噪声低,舒适性提高,且转向桥总成和电动助力系统的模块化设计,适配不同车型。
