PURPOSE:To assure a conveyor vehicle to run over a bulged ground smoothly and surely by equipping a conveyor vehicle, having four or more independent drive axles, with elastical suspension mechanisms independently only for the foremost and backmost wheels. CONSTITUTION:Only foremost and backmost wheels 1a,... are supported by elastical suspension mechanisms 28 independently to give them possibility of vertical motion individually while other wheels 1,... in the front and rear and in the middle are installed with fixed location. When the vehicle wants to run over a ridge 30, the wheel 1a at the front will rise followed by the wheel 1a at the backmost, so that running-over of a ridge 30 is conducted smoothly. Furter, the wheel 1a at the backmost and other fixed wheel 1 in front thereof contact the ground at times, so that no lack of thrust force will be brought about to assure a sure running-over. |
