PURPOSE: To allow a cross-country vehicle to make movement on an up-and- down ground by equipping it with a chassis frame, an upper structure, wheels capable of height adjustment and application of brakes, moving legs capable of being driven individually, and a frame supporting device with the height adjustable. CONSTITUTION: A chassis frame 10 is enwrapped in such a way that one end is furnished with a center wheel 20 borne on two vehicle arms 15 with the height and the left-right adjustable while the other end is equipped with two moving legs 25 and 26 adjustable to the left and right consisting of straps 38 movable in all directions. A supporting device 22 pith height adjustable is installed to support the chassis frame 10 during a change of the running speed or in the period the legs are moving simultaneously, and a lower bracket 35 is tied with an upper bracket 33 irrespective of its inclination. Bending and elongation of the legs 25 and 26 are made actuatable simultaneously by a hydraulic drive device. Thereby the vehicle can move forward and backward on a ground out of flatness. |
