<p>This specification discloses a resilient wheel suspension (10) wherein a wheel (11) is rotationally mounted upon an axle (12) and the axle is resiliently suspended with respect to a mounting plate (14). The resilient suspension includes an elastomer disk (60) which is coupled along one major surface to the axle (12) and along the other major surface to the mounting plate. The axle is coupled eccentrically to the elastomer disk so that the axle axis is offset from the central axis of the elastomer disk. Lateral movement of the axle causes a shear to be applied in the elastomer disk. The eccentric mounting provides increased suspension travel, more ground clearance and more wheel mounting clearance with respect to a concentric mounting. The suspension can have nonlinear characteristics by having a plurality of elastomer disks (60, 61, 62) and metal disks (55, 56, 57, 58) with central openings for passing the axle and successively coupled to adjacent disks between a coupling to the axle and a coupling to the mounting plate. The size of the opening diameter increases in successive disks going from the disk adjacent to the axle to the disk adjacent to the mounting plate. Successive disks are also mounted eccentrically with respect to the axle.</p> |
