Support frame for auxiliary power unit for a motor vehicle

摘要

An auxiliary power system for a long-haul truck includes a first frame which has an auxiliary power unit mounted thereon using elastomeric isolation mounts. A second frame is affixed in a stationary position to an exterior surface of a single longitudinal rail of the vehicle frame. There is a pair of spring elements each operable in a vertical direction and having a first end thereof pivotally connected to a respective side member of the first frame and having a second end thereof pivotally connected to a respective side member of the second frame, whereby the first frame is capable of moving in a vertical plane relative to the second frame for isolating the auxiliary power unit from the effects of road shock and vibration. Elastomeric isolation mounts are also provided for controlling downward movement of the first frame.
