The multi-mode steering system of the snow sweeper comprises a hydraulic oil tank, a controller, a front axle steering device, a duplex steering pump and a steering machine, a pressure input port of the duplex steering pump is communicated with the hydraulic oil tank, a first pressure output port of the duplex steering pump is communicated with the steering machine, and an oil return port of the steering machine is communicated with the hydraulic oil tank; the rear axle steering device comprises a first reversing valve, at least two angle sensors and a two-way cylinder, the first reversing valve is communicated with a second pressure output port of the duplex steering pump, the controller is electrically connected with the first reversing valve and the angle sensors, and the angle sensors are used for collecting steering angle information of front and rear wheels; the controller is used for receiving the turning angle information of the front and rear wheels and sending an electro-hydraulic proportional control signal to the first reversing valve. The snow sweeper has the advantages that the snow sweeper can be conveniently moved, the single-time snow pushing width is increased, the snow removing efficiency is improved, the turning radius of the snow sweeper is reduced, and the effect that the snow sweeper steers in a narrow space is achieved.

    本发明涉及一种除雪车多模态转向系统,包括液压油箱、控制器、前桥转向装置、双联转向泵和转向机,双联转向泵的压力输入口与液压油箱连通,双联转向泵的第一压力输出口与转向机连通,转向机的回油口与液压油箱连通;后桥转向装置,包括第一换向阀、至少两个角度传感器和双向缸,第一换向阀与双联转向泵的第二压力输出口连通,控制器分别电连接第一换向阀和多个角度传感器,角度传感器用于采集前后车轮转角信息,控制器用于接收前后车轮转角信息并向第一换向阀发出电液比例控制信号,本申请具有方便除雪车挪车,增加单次推雪宽度,提高除雪效率,减小除雪车的转弯半径,实现除雪车在狭小空间内转向的效果。
