Abstract
Abstract In accordance with the presently preferred embodiment of this invention, a motor vehicle chassis includes a subframe of generally box shape that is supported on a vehicle frame by four resilient mounts. An independent front suspension has some of its suspension members pivotally supported on the vehicle frame and some pivotally supported on the subframe by resilient pivots. A vehicle power plant is supported on the subframe by a resilient mount. Suspension vibrations are isolated from the passenger carrying vehicle body supported on the frame by the resilient pivots which connect the suspension members to the subframe and the resilient mounts which connect the subframe to the regular vehicle frame. Power plant vibrations are isolated from the vehicle body by the resilient mount which connects the power plant to the subframe and the resilient mounts which connect the subframe to the vehicle frame.
