Abstract

An independent wheel suspension system having a pair of wheel assemblies, a transverse support member rotatably connected between side frame members of the vehicle frame to pivot about a transverse pivot axis, a differential attached to the transverse support member, a prop shaft coupling the differential and the vehicle engine with universal joints, one of the joints being of the constant velocity plunging type, and a trailing arm pivotably connecting each wheel assembly to the transverse support member, the trailing arm having a wheel end coupled to the wheel assembly and a pair of spaced-apart support sections defining a swing axis therebetween pivotably coupled to the transverse support member so that the swing axis is substantially perpendicular to the wheel axis of the wheel assembly and substantially parallel to the prop shaft axis of the prop shaft, whereby relative motion is allowed about the swing axis between the differential and the wheel assembly while also permitting relative motion about the transverse pivot axis between the vehicle frame and both the differential and the wheel assemblies, while also permitting relative movement between each of the foregoing elements and the driving surface about a drive axis established by a drive shaft coupling the wheel assembly to the differential.
