A motor vehicle includes a body, which body has at least two rear longitudinal members each forming a primary load path for collision forces, wherein the motor vehicle has a rear-end module that can be pre-assembled as a sub-assembly, which rear-end module can be connected to the body as part of the vehicle assembly after the completion of the body-in-white and has at least a supporting structure for fastening chassis components of a rear wheel suspension and a beam structure extending from the supporting structure toward the motor-vehicle rear for absorbing collision forces, wherein the supporting structure and the beam structure form at least one second load path for collision forces.

The invention relates to a subframe (1) for a motor vehicle, comprising at least three beams, of which, in the assembled state of the subframe, at least two beams (3, 4) extend at a distance from one another, substantially along the longitudinal axis of the motor vehicle and at least one beam (6, 7) extends transversely to the longitudinal axis of the motor vehicle, at least one of the beams being an extruded beam (3, 4), and at least one cast node (11) of aluminium, magnesium or an alloy based on aluminium and/or magnesium, the cast node (11) connecting the extruded beam (4) and at least one of the other beams (6) to another, wherein the cast node (11) has an arm-shaped beam connecting element (11.4), wherein the extruded beam (4) overlaps the beam connecting element (11.4), and wherein the extruded beam (4) is connected to the beam connecting element (11.4) by a weld seam (14). In order to improve such a subframe with regard to high strength and durability and low weight of the subframe, the invention provides that the cast node (11) has on the beam connecting element (11.4) a shoulder which defines a shoulder end face (16), wherein the shoulder end face (16) on the one hand and the extruded support (4) and/or the weld seam (14) on the extruded beam (4) on the other hand define a groove-shaped or trench-shaped recess (17), whose width or average width (W) is at least 2.5 times, preferably at least 3.5 times, particularly preferably at least 4 times, the wall thickness (te) of the extruded beam (4), and wherein the weld seam (14) is designed as a lap seam.

A method for producing a motor vehicle component includes the steps of providing a precipitation-hardenable blank composed of a 6000 or 7000 grade aluminum alloy, solution-annealing the blank at a temperature between 350° C. and 550° C. for a time period of 2 to 30 min., in particular 3 to 20 min. and preferably 5 to 15 min., in particular at a temperature between 440° C. and 480° C. in the case of a 7000 grade aluminum alloy, and in particular at a temperature between 490° C. and 545° C. in the case of a 6000 grade aluminum alloy, subjecting the solution-annealed blank to partially different quenching, a first region being quenched to a temperature between 150° C. and 250° C., and a further region being quenched to a temperature below 150° C., deforming the blank during or after the partially different quenching.

A hollow structure for installation as cross member or longitudinal member in a motor vehicle includes a hollow member which is made of light metal and has at least one hollow chamber. The hollow member has a wall which is formed with a slot. A flange sized to extend through the slot has a leg configured to rest by a formfit against a side of an inner surface area of the hollow member and at least one area which is coupled to an outer surface area of the hollow member.

A method is provided for enhancing in-service structural performance of a sheet metal component incorporating a discontinuity. The method comprises heat-treating a zone of the sheet metal component a predetermined distance from the discontinuity thereby changing the strength and ductility of the zone and shifting the deformation induced in the sheet metal component by a subsequent deformation event away from the discontinuity to the zone.
