An articulated off-road vehicle is shown, having a front body portion and a rear body portion, connected for pivotal movements relative to each other about a substantially vertical axis, and for twisting movements relative to each other about a longitudinally extending, substantially horizontal axis. A drive shaft powered by an engine extends through the connections between the body portions, and is provided with a universal joint to accommodate the pivotal movement. An axle is mounted on each body portion and a differential for each axle is driven by the drive shaft. A wheel assembly, mounted on each end of each axle, has first and second wheel support arms each journaled at an upper end thereof on the axle, with the first arm extending forwardly and downwardly therefrom, and the second arm extending rearwardly and downwardly therefrom. A wheel is rotatably mounted on the lower end of each arm and a drive chain extends from the axle to each wheel for driving the wheel. A spring is connected between the arms intermediate the ends thereof to exert a force tending to draw the arms and attached wheels together.
