The invention discloses a heavy truck and a steering system thereof. The steering system comprises a hydraulic steering gear, a steering wheel, a rotary driving mechanism and a control unit. The steering wheel is connected with the hydraulic steering gear and used for providing steering torque needed by steering for the hydraulic steering gear, the rotary driving mechanism is connected with the hydraulic steering gear and used for providing rotating torque for the hydraulic steering gear so as to provide assisting power or resistance for steering operation of the steering wheel, and the control unit is connected with the rotary driving mechanism. The control mechanism is used for controlling the rotation driving mechanism to rotate according to the steering torque of the steering wheel and whole truck signals of the heavy truck. According to the steering system, the size and size of the overall structure of the steering system are reduced through integrated design, system installation is facilitated, cost and the weight of the whole truck are reduced, traditional single hydraulic steering is converted into electric and hydraulic dual control, and therefore the steering development requirements of heavy truck models for safety, diversification and intelligentization are met.
本申请公开了一种重型卡车及其转向系统,转向系统包括液压转向器、方向盘、旋转驱动机构和控制单元。方向盘连接液压转向器,用于向液压转向器提供转向所需的转向力矩,旋转驱动机构连接液压转向器,用于向液压转向器提供转动力矩,以对方向盘的转向操作提供助力或阻力,控制单元连接旋转驱动机构,用于根据方向盘的转向力矩大小和重型卡车的整车信号控制旋转驱动机构旋转。上述转向系统,通过集成化设计以减少转向系统整体结构的尺寸和大小,不仅便于系统安装,而且降低了成本和整车重量,同时,由传统的单一液压转向转换为电+液压双重控制,从而满足重卡车型安全性、多元化、智能化的转向发展需求。
