A pair of front couplings and a pair of rear air spring over shocks couple the cab to the vehicle frame. A motion control link includes a central base and pair of arms extending longitudinally from the central base. A base coupling directly couples the base to the vehicle frame. A rear arm coupling for each arm directly couples the arm to the rear of the cab. The rear base coupling and the rear arm coupling essentially restrict lateral movement of the motion control link and permit tuned lateral movement of the frame relative to the rear of the cab to provide lateral motion control at the rear of the cab. The motion control link defines an arc that intersects the front coupling arc. The rear arm couplings include a rear elastomeric bushing member including voids to accommodate for the intersecting arcs.

Driver's cab suspension

A torque rod assembly includes a pair of end joint assemblies with a thin wall connecting tube disposed between them. The end joint assemblies each include an eye which is friction welded to the thin wall connecting tube. The use of the thin wall connecting tube and the friction welding process allow the friction weld to be located immediately adjacent a bore extending through the eye. The eyes and the thin wall connecting tube can be cast, extruded or formed from steel, aluminum or cast iron.

Optimized wall thickness torque rod

A V-shaped torque rod includes an apex joint assembly that is attached to a component of a vehicle using only a single fastener. The apex joint assembly includes a housing, an inner metal, an elastomeric member disposed between the housing and the inner metal and a post that engages the inner metal. The single fastener extends through the inner metal and through the post to secure the apex joint assembly to the vehicle. The post can be a tapered post or the post can be a non-tapered post.
