ABSTRACT:
An all-terrain vehicle having two bogies movably joined at their inner ends and pivotally mounted on each side of the vehicle and two main wheels mounted on the ends of one of the bogies and a third wheel mounted on the other end of the other bogie. The outer ends of the bogies extend beyond the vehicle body and have auxiliary wheels mounted on such outer ends on the opposite sides of the bogies from the main wheels. A gear drive is provided for driving each of the auxiliary wheels at the same peripheral speed as the main wheels. The vehicle can also have a limited differential for permitting limited relative rotational motion between wheels on opposite sides of the differential but supplying a positive drive thereto at the end of such limited travel. The vehicle can also have a torsion bar drive or a limited travel torsion bar drive between the various bogie-mounted wheels to thereby permit relative rotational movement therebetween while still providing positive drives thereto. A double-bogie vehicle is also disclosed, as described above, which has spring-shock struts suspending the wheels between the vehicle body and the bogies. A bogie suspension is also disclosed wherein one or more of the independently spring-shock mounted wheels has a drive and/or a steering linkage attached thereto.
