Heavy duty motor vehicle cab suspension

摘要

An apparatus for supporting a cab of a conventional over-the-highway truck or tractor vehicle relative to a vehicle frame which includes a pair of longitudinally extending rails and a transverse member interconnecting the rails. A pair of mounting assemblies are located near the front of the cab to resiliently and pivotally connect the cab to the rails. A pair of spaced apart spring members are located near the rear of the cab to support the cab for limited movement relative to the frame. A spaced pair of dampers extends between the cab and the frame to damp movement of the cab. The spaced dampers are located between the spring members. A centering damper is mounted between the cab and the frame to damp transverse movement of the cab. The centering damper is located between the spaced dampers.
