The invention discloses a wireless remote control automatic steering device of a fire fighting truck, and relates to the technical field of wireless remote control automatic steering. A two-position four-way electromagnetic reversing valve enables an oil way I to be communicated with an oil way II when an electromagnetic valve Y1 of the two-position four-way electromagnetic reversing valve is not powered on; when the electromagnetic valve Y1 is powered on, the first oil way I is communicated with the fifth oil way. The electromagnetic valve Y4 is used for controlling opening and closing of an oil way III; the electromagnetic valve Y5 is used for controlling opening and closing of an oil way IV; the three-position four-way electromagnetic reversing valve enables an oil way V to be communicated with an oil way IV I and an oil way III I to be communicated with an oil way VI when the electromagnetic valve Y2 is powered on, and enables the oil way V to be communicated with the oil way III I and the oil way IV I to be communicated with the oil way VI when the electromagnetic valve Y3 is powered on. The sixth oil way is communicated with the second oil way. According to the invention, the dual modes of personnel steering wheel steering and remote control steering can be realized only by being embedded into the steering system of the existing fire fighting truck, the steering system of the fire fighting truck does not need to be integrally replaced, and great economic benefits are achieved.
本发明公开了一种消防车无线遥控自动转向装置,涉及无线遥控自动转向技术领域,一种消防车无线遥控自动转向装置,其二位四通电磁换向阀在其电磁阀Y1未给电时使油路一Ⅰ与油路一Ⅱ连通,其在其电磁阀Y1给电时使油路一Ⅰ与油路五连通;电磁阀Y4用于控制油路三开合;电磁阀Y5用于控制油路四开合;三位四通电磁换向阀在电磁阀Y2给电时使油路五与油路四Ⅰ连通且油路三Ⅰ与油路六连通,在电磁阀Y3给电时使油路五与油路三Ⅰ连通且油路四Ⅰ与油路六连通;油路六与油路二连通。本发明只需嵌入到现有的消防车的转向系统中去即可实现人员方向盘转向与遥控转向双模式,无需对消防车的转向系统进行整体更换,具有非常大的经济效益。
