TRAILING ARM SUSPENSION WITH WRAPPER COMPRESSION AXLE MOUNTING

摘要

A vehicle suspension system (l6) for mounting ground-engaging wheels (l4) to a vehicle frame where two arms (l8) are secured to opposite sides of the frame and a wheel-carrying axle (l2) is suspended between the arms (l8). The axle (l2) is secured to the arms (l8) by a wrapper plate (34) partially surrounding the axle (l2), and a bolt (38) is utilized to compress the wrapper plate (34) about the axle (l2) so that the wrapper plate (34) supports and strengthens the axle. A plug weld (42) is provided between the axle (l2) and the wrapper plate (34). The wrapper generally conforms to the profile of that portion of the axle (l2) which it surrounds. The axle (l2) can be square, round or D-shaped in cross-section.
