Abstract
A vehicle suspension system for mounting ground-engaging wheels to a vehicle frame where two arms are secured to opposite sides of the frame and a wheel-carrying axle is suspended between the arms. The axle is secured to the arms by a wrapper plate partially surrounding the axle, and a bolt is utilized to compress the wrapper plate about the axle so that the wrapper plate supports and strengthens the axle. A plug weld is provided between the axle and the wrapper plate. The wrapper generally conforms to the profile of that portion of the axle which it surrounds. The axle can be square, round or D-shaped in cross-section.
