The invention relates to a four-wheel steering device of a fire fighting truck, which comprises a frame, a steering driving mechanism connected with the frame and used for providing steering driving force; the steering control mechanism is connected with the steering driving mechanism; the Ackerman steering mechanism comprises a first steering mechanism and a second steering mechanism which are arranged on the frame; and the steering transmission mechanism comprises a first steering connecting rod of which one end is rotationally connected with the first steering mechanism, a second steering connecting rod of which one end is rotationally connected with the second steering mechanism, and a telescopic rod assembly which is rotationally connected with the other end of the first steering connecting rod and the other end of the second steering connecting rod. The four-wheel steering device of the fire fighting truck is simple in structure, the turning radius can be obviously reduced, meanwhile, steering can be dynamically adjusted according to the real-time road surface state, various road surfaces can be effectively handled, the maneuverability and flexibility of the fire fighting truck in a lower gate space are improved, and therefore the rescue efficiency of the fire fighting truck is effectively improved.

    本发明涉及一种消防车四轮转向装置,包括:车架,转向驱动机构,与所述车架连接,用于提供转向的驱动力;转向控制机构,与所述转向驱动机构连接;阿克曼转向机构,包括设置于车架上的第一转向机构和第二转向机构;以及转向传递机构,包括一端与所述第一转向机构转动连接的第一转向连接杆,一端与所述第二转向机构转动连接的第二转向连接杆,以及转动连接第一转向连接杆的另一端和第二转向连接杆的另一端的伸缩杆组件。本发明的消防车四轮转向装置不仅结构简单,还能够明显缩小转弯半径,同时能够根据实时路面状态动态调整转向,有效应对各类路面,提高消防车在下闸空间中的机动性和灵活性,从而有效提高消防车的救援效率。
