Abstract
The invention is directed to a suspension arm that is constructed and arranged to elastically absorb transverse and longitudinal forces transferred from the wheels of a vehicle to the supporting structure. The supporting structure comprises two hollow rear axle supports, each formed by a high interior pressure metal forming process. The rear axle supports each have a variable cross-sectional shape and are connected to one another. Fastening devices are attached at opposite ends of each of the two hollow rear axle supports and are adapted for fastening the support structure to a vehicle.

A suspension arm for fastening wheels to a vehicle having a longitudinal axis, said suspension arm comprising a supporting structure constructed and arranged to elastically absorb transverse and longitudinal forces transferred from the wheels to the supporting structure, said supporting structure comprising:
- two hollow rear axle supports, each formed by a high interior pressure metal forming process, said hollow rear axle supports each having a variable cross-sectional shape and being connected to one another, said two hollow rear axle supports each extending generally in a direction transverse to said longitudinal axis and being undulated along their respective lengths to define two wave troughs, said two hollow rear axle supports being arranged in opposing relation to each other so that the respective wave troughs contact one another at two points and are welded to one another at said two points;
- and
- fastening devices attached at opposite ends of each of said two hollow rear axle supports adapted for fastening said support structure to a vehicle.
