Multiaxle mechanical steering controlling device

The utility model relates to a many-bridge mechanical steering controlling device for special type automobiles, whose bridges turn around synchronously. At least one steering bridges are added to the utility model on the basic of one-bridge mechanical steering controlling devices and two-bridge mechanical steering controlling devices, a steering control connecting bar assembly is arranged on every former vehicle-bridge which is changed into a steering bridge, then former vehicle-bridge becomes a steering bridge, the steering control connecting bar assembly is connected with a deflecting roller via a steering king pin of a straight-drawing pole assembly (7'), the steering control connecting bar assembly is connected with a rocking arm (5) of the former steering bridge via a steering longitudinal tie assembly, and the rear steering bridge and the former steering bridge turn around synchronously, so a plurality of bridges turn around synchronously, the diameter of minimal turning circle of the many-bridge special type automobile is reduced sharply, thereby improving maneuverability of automobiles and reducing rotational resistance.
