ABSTRACT:
A suspension system includes first and second frame hangers mounted to the supported frame member. A single-leaf leaf spring of the system includes an eye formed at its proximal end. The eye is pivotally connected to the frame member at the first frame hanger and the distal end portion of the leaf spring is connected to the frame member at the second frame hanger. A leaf spring attachment part mounts to the distal end portion of the leaf spring and connects it with the second frame hanger. The leaf spring attachment part includes a sleeve having an axially extending bore. The sleeve is sized and shaped to accommodate a rod, such as a pin or pivot bolt, to connect the distal end portion of the leaf spring and the leaf spring attachment part with the second frame hanger. When it is so connected, the leaf spring attachment part restricts the movement of the leaf spring to a controlled range. The pin or pivot bolt lies coincident with an axis defining the natural center of rotation for the distal end portion of the leaf spring to permit natural movement of that distal end portion during jounce and rebound action of the associated axle. A thrust washer is secured to the leaf spring attachment member to absorb lateral forces and prevent wear of the second frame hanger.
