Isolation system from noise and vibrations for a work vehicle

Abstract:

An isolation system for a vehicle having a rear frame attached to a front frame. The rear frame supports a greater portion of a total force applied to the vehicle than the front frame. The isolation system includes at least one isolating device positioned between the rear and front frames. The isolating device supports a portion of the total force applied to the vehicle in a direction in which the isolating devices is positioned. The isolation system includes a force limiting device positioned near the isolating device and a motion limiting torque rod attached to the rear and front frames. The force limiting device limits the amount of load applied to the isolating device above a maximum load. The motion limiting torque rod prevents or limits movement of the rear frame relative to the front frame in the direction in which it is aligned.
