The invention relates to an integral motor vehicle rear axle of the twist-beam axle type, which comprises an opposed pair of longitudinal control arms (2) of a high flexural strength and torsional stiffness for carrying a wheel carrier for a wheel, and a transverse strut (3) which is resistant to bending but resilient relative to torsional stress and which comprises a profiled cross-section changing the position of the shear center. The transverse strut (3) consists of an extruded aluminum profile with an extrusion structure extending in the longitudinal direction of the transverse strut. A method of producing a motor vehicle rear axle of the twist-beam axle type using transverse struts and longitudinal control arms consists in joining the longitudinal control arms (2) with a transverse carrier or strut (3) which, at each end, comprises a bore, opening or bonding surface extending transversely to the longitudinal axis, and in connecting said longitudinal control arms in a form-fitting and force-locking way, such as by hydro-forming, welding or similar methods.

Twist beam axle and method of producing same

A motor vehicle door has an outer panel and an inner panel. The outer panel is made up of a pair of double-walled, hollow structural members which are self-supporting. A door lock and door hinges are mounted on the outer panel. The inner panel, which is connected to the outer panel, carries all remaining accessories associated with the door, such as the operating mechanisms for a window mounted on the door.
