Abstract
A multi-axle leaf spring suspension having a compliant equalizer. The leaf springs are mounted one behind the other on each side of the vehicle. Adjacent ends of the leaf springs are pivotally attached to the compliant equalizer. The compliant equalizer is pivotally mounted to a vehicle frame. The compliant equalizer comprises a pair of arms that are pivotally connected to each other in a scissor-like fashion. One end of each arm is pivotally connected to the end of a leaf spring. The other end of each arm is cooperatively arranged to contain and compress a spring member between them. The compliant equalizer reduces the magnitude of shocks that would be other wise transmitted to the suspension and frame by absorbing them through compression of the spring member.
