ABSTRACT:
A spring for use in a vehicle suspension comprises at least one leaf having longitudinal ends tapering outwardly from one end of the spring to the other to form a substantially trapezoidal shaped leaf spring. The leaf is resiliently biased by a spring constant to a normally semi-elliptical shape which deflects into a substantially linear orientation when the vehicle supported upon a ground surface by the suspension. The linear orientation of the usually semi-elliptical spring maximizes resistance to lateral distortion in the direction normal to the longitudinal axis of the spring. Preferably, the spring comprises a single leaf having tapered longitudinal edges and an eye at each longitudinal end adapted to receive a mounting pin therethrough.
