Abstract
A utility vehicle is provided with a middle axle that is mounted at the end of a bogey beam for flotational movement relative to the frame of the vehicle. The middle axle is restrained longitudinally by support links that are pivotally connected at a location forward of the rear drive axle. The middle axle is formed by a pair of stub axles interconnected by a support beam that is pivotally connected to the rearward end of the bogey beam. Vertical movement of the middle axle support wheels results in a corresponding vertical movement of the rearward end of the bogey beam and a rotation of the support beam about its pivotal connection on the bogey beam. The configuration of the support links provides sufficient slack in the drive mechanism to the middle axle during flotational movement thereof so as to allow a slight twisting of the drive mechanism during oscillation of the middle axle.
