COMPOSITE LEAF SPRING CONSTRUCTION HAVING DIFFERENT SPRING RATE FOR THE FRONT AND REAR PORTIONS OF THE SPRING A composite leaf spring construction for a vehicle having different spring rates for the front and rear sections of the spring to control rotation of the differential under heavy load conditions. The leaf spring is composed of fiber reinforced resin and has a constant cross sectional area throughout its length. The front section of the spring has a greater thickness and lesser width than the rear section, thereby providing the front section with a higher spring rate. The vehicle axle is mounted on the front section of the spring forwardly of the transition zone between the sections. The differential spring rate controls rotation of the differential housing and prevents the housing from engaging the floor of a low profile vehicle under heavy load conditions.
