Abstract

The invention relates to a vehicle suspension comprising a pair of leaf springs (61) arranged to extend longitudinally on opposed sides of a vehicle frame. Each leaf spring (61) has a first end pivotally connected to the vehicle with a first bracket (63) attached rigidly to the frame at a first position (71). A second end is connected to the vehicle frame with a spring shackle pivotably connected to a second bracket (64) attached rigidly to the frame at a second position in order to compensate for length changes of the leaf spring (61) under load conditions. The suspension further comprises an axle (66) extending transversely of the vehicle frame which axle is mounted to each leaf spring (61) at a position intermediate its first and second ends. At least an upper leaf of the leaf spring (61) is a parabolic spring having a convex portion (70) extending towards the frame and that the convex portion (70) is located between the first end and the intermediate position.
