The invention discloses an automatic steering system and a mining dump truck. The automatic steering system comprises an automatic control valve group, a flow amplifier, a steering oil cylinder and a vehicle-mounted basic steering gear, the self-control valve group, the flow amplifier and the steering oil cylinder are connected through a hydraulic pipeline, the self-control valve group is electrically connected with a vehicle-mounted control module and used for receiving an operation instruction, executing corresponding actions and controlling the flow and the flow direction of hydraulic oil, and the hydraulic oil enters the steering oil cylinder through the flow amplifier and flows into the vehicle-mounted control module. And then the steering oil cylinder is controlled to act to complete automatic steering. The vehicle-mounted basic steering gear is connected between the steering wheel and the flow amplifying valve and used for controlling the flow amplifying valve to act when the steering wheel rotates so as to control the steering oil cylinder to act to complete manual steering. An automatic steering function is added on the basis of original manual steering of a steering wheel, remote electric control steering can be achieved, vehicle steering automation is achieved, and operation difficulty and labor intensity are reduced.

    本发明公开了一种自动转向系统及矿用自卸车,该自动转向系统包括:自控阀组、流量放大器、转向油缸以及车载基本转向器;所述自控阀组、所述流量放大器和所述转向油缸通过液压管路连接,所述自控阀组与车载控制模块电性连接,用于接收操作指令并执行对应的动作,控制液压油的流量和流向,液压油经过所述流量放大器进入所述转向油缸,进而控制所述转向油缸动作完成自动转向;所述车载基本转向器连接在方向盘和流量放大阀之间,用于在方向盘转动时控制流量放大阀动作进而控制所述转向油缸动作完成手动转向。在原有人工操纵方向盘转向基础上增加自动转向功能,可实现远程电控操纵转向,实现车辆转向自动化,降低了操作难度和劳动强度。
