A chassis structure for a motor vehicle includes an extruded base member made of light metal and a reinforcing member made of steel to reinforce the base member. The base member has two walls which are spaced from one another by a distance, with the reinforcing member connecting free ends of the walls. The reinforcing member and the base member are joined to one another using electromagnetic pulse welding.

An undercarriage assembly and related method for motor vehicles includes a base and a support positioned adjacent to the base at a connection area. At least one nail is inserted into the support and the base of the connection area, which rigidly connects the support with the base without any pre-formed fastener holes.

An adaptive crash structure of a vehicle body or chassis of a motor vehicle includes a first metal casting and a second metal casting. A deformation element in the form of a metal casting for absorbing energy interconnects and forms with the first and second metal castings a single piece construction through a casting process. The deformation element is comprised of a plurality of funnel-shaped wedge bodies which are disposed in succession, with neighboring wedge bodies being connected through intervention of a predetermined breaking web. Each wedge body is defined by a diameter, wherein the diameters of the wedge bodies are sized to allow the wedge bodies to move telescopically into one another when a limit stress is reached and the predetermined breaking webs rupture so as to effect a tight intergrip of the telescoping wedge bodies in a self-locking manner.

A control arm includes a connection tube and two mounting eyes respectively attached to opposite ends of the tube. Each mounting eye has a sleeve and a rubber-metal element vulcanized into the sleeve. In a method of making such a control arm, an elongate tubular member is sized to a sleeve blank of a length commensurate with the tube. Parallel thereto, an extruded profile is made with a cross sectional configuration of the sleeve and subsequently sized to the axial height of the sleeve. Rubber-metal elements are vulcanized into the sleeve blanks which together with the tube are then clamped, axially shiftable, in a friction welding machine for subsequently fabricating protruding collars on the sleeves through material removal and joining the end surfaces of the protruding collars with the end surfaces of the tube. While still clamped, the tube and the mounting eyes are calibrated through cold upsetting and the joints are smoothed.
