Abstract

A V-bar suspension linkage is shown and described. In a preferred embodiment, two arms are mounted between the axle and the vehicle frame rails, the arms extending outwardly at an angle to each other to form a "V" shaped linkage, having its vertex at the axle. The first end of each arm is coupled to the axle via a vertically oriented bushing pin that is secured to an axle bracket which in turn is mounted on the axle. By vertically mounting the bushing pins, the ends of the arms may be closer together, thereby increasing the angle between the arms and reducing the stresses in the arms and bushings. The distal end of each arm is coupled to a frame rail via a vertically oriented bushing pin that is secured in place by anchor lugs that are provided on upper and lower gussets that form part of the vehicle frame assembly. The pitch and lateral placement of the axle is easily adjusted at the axle via use of spacers between the axle bracket and bushing pins.
