A hydraulic steering system for a mine car, including a hydraulic steering mechanism on the frame. The hydraulic steering mechanism includes a hydraulic oil tank. The hydraulic oil tank is connected to the steering pump through the oil road. The steering pump is connected to the priority valve through the oil path. The priority valves are connected to the steering gear through the oil road. The steering gear is turned to the left by the oil path. The cylinder is connected with the right steering cylinder, and the steering gear is connected with an oil block through the oil path, and the oil return block is connected with the hydraulic oil tank through the oil path. The design of the utility model is reasonable. The steering pump connects the hydraulic oil tank and the priority valve through the oil road. The priority valve connects the steering gear and the oil recovery block through the hydraulic oil road. When turning the steering wheel, the priority valve switches the oil path to the steering gear. With the speed of turning the steering wheel, the priority valve provides the appropriate flow to the steering gear and ensures the steering. The process is portable; the system realizes the first application of the full hydraulic steering system on the wide body dump truck, and solves the problem of the high failure rate of the traditional hydraulic power steering system.
