Abstract
A vehicle suspension is described for a vehicle whose frame is supported through leaf springs lying on the axles, which avoids reverse bending of the springs while also providing a smoother ride. The system includes an air sleeve having an upper end mounted on the vehicle frame and a lower end bearing against the top of the leaf spring at a location between the axle and the front of the spring. The distance between the axle and the air sleeve is about 38% of the total distance between the axle and the front of the spring where it is connected to the frame, this spacing having been found to provide maximum shock absorbtion and smoothness of ride.
