Abstract
Provided are wedging and clamping mechanisms for securing an axle to a suspension member. The suspension member has a integral axle shell for seating the axle to be attached. An axle wedging shell is provided which mates to the axle shell via aligning angled grooves and flanges which, as the flanges are forced into the grooves, creates a significant clamping force trapping the axle in place. The orientation and placement of angled grooves and flanges varies through several embodiments. Some embodiments alternately use a retention plate. Adhesive may be applied to the axle and the inner surfaces of the axle shell and wedge member to limit axle twist or rotation.
