Abstract: The independent suspension includes a suspension system and a support assembly. The support assembly generally includes a central member having a first end and a second end to which first and second end members are coupled. The support assembly generally spans between vehicle rails with the central member acting as a structural bridge between the end members. The central member defines a cavity and an input passage communicating with the cavity. A driveshaft may be coupled to an input member retained within the input passage which in turn is operably coupled to a torque transferring device disposed within the cavity. The torque transferring device transfers torque from the input member to a pair of output shafts. The end members are also coupled to a suspension system so that the end members may receive suspension load from the suspension system and transfer the suspension load to the other end member through the central member.

Abstract: A support assembly for an independent rear suspension includes a generally-tubular central member having first end and a second end. A U-shaped end member is coupled to each end of the central member, such that the end members are structurally bridged by the central member. Lands defined on the ends of the arms of each end member are adapted to engage the vehicle frame rails through suitable isolation mounts. An attachment point defined on each end member is adapted to pivotally support a lateral link coupling a respective wheelend assembly to the support assembly. The central member advantageously defines at least a portion of a housing adapted to receive a driveline component, such as an electric motor, coupled to the vehicle's rear wheelend assemblies by a pair of shafts extending from the central member, with the further benefit that the shared suspension and driveline isolation mounts providing enhanced NVH characteristics.

Abstract: A suspension subframe for a vehicle is disclosed comprising a plurality of metal tubes standardized for use in vehicle exhaust systems, such as those defined by 1.5 mm gauge walls, that are affixed to each other. A structural foam material, such as an epoxy-based foam, is positioned within the metal tubes. Also provided is a method for making a suspension subframe for a vehicle comprising providing a plurality of metal tubes standardized for use in vehicle exhaust systems, such as those defined by 1.5 mm gauge walls. The metal tubes are welded together in a desired shape and a structural foam material, such as an epoxy based foam, is inserted into the tubes.

Abstract: A vehicle suspension system which uses a beam spring capable of substantial elastic deformation in two planes to provide for independent wheel suspension and to commonize suspension mounting systems in a vehicle chassis.
