<p>A vehicle suspension system for mounting ground-engaging wheels to a vehicle frame (10) where two arms (18) are secured to opposite sides of the frame and a wheel-carrying axle (12) is suspended between the arms. The axle is secured to the arms by a wrapper plate (34) partially surrounding the axle, adapter plates (39) mounted to the interior surface of the wrapper plate and at least one bolt (38) to compress the wrapper about the axle and the adapter plate against the axle. In this configuration, the wrapper plate supports and strengthens the axle. The wrapper plate generally conforms to the profile of that portion of the axle which it surrounds. The axle can be square, oval, hexagon, octagon, rectangular or D-shaped in cross section. The wrapper plate and the adapter plates exert substantially transverse forces on the axle. An aperture (42) is formed in the wrapper plate in the side thereof in a location corresponding to the vertical midpoint of the adjacent side of the axle. A circular washer (44) is welded to the axle on each side thereof in registry with the apertures in the side of the wrapper plate to prevent lateral translation of the wrapper plate with respect to the axle.</p> |
