Abstract

A vehicle suspension having a first load-bearing component assembly and a second load-bearing component assembly. The first and second load bearing component assemblies are adapted to be transversely positioned across from each other on a vehicle chassis. Each load-bearing component assembly comprises a wheel hub, an upper control arm having an apex portion and a base portion, and a lower control arm having an apex portion and a base portion, and each wheel hub is supported between the apex portions of the upper control arm and the lower control arm of the respective load-bearing component assemblies. The base portion of each of the upper and lower control arms of the respective load-bearing component assemblies is adapted to be pivotally secured to a vehicle chassis to permit upward and downward vertical movement of each wheel hub, relative to a rest state, in response to load variations. A directionally-dependent heave spring assembly is adapted to be transversely secured to a vehicle chassis, the heave spring assembly is coupled to the first load-bearing component assembly and to the second load-bearing component assembly and exhibits resiliency in opposition to upward vertical movement of both wheel hub assemblies relative to their rest states, and exhibits substantially no resiliency in opposition to downward vertical movement of both wheel assemblies relative to their rest states.
