A method of making a beam-box crash management system comprises forming a first shell () from a first sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion () and integrally formed there-with a first low yield strength crash box portion () proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (). A closing element () is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

Bumper assembly

A subframe () designed as a cross member for a vehicle includes two side members () and a stiffening structure () between the two side members (), wherein the side members () are designed substantially as hollow profile pieces and have at least one predetermined buckling point () in the form of a curvature in the longitudinal extension direction of the side members (). In order to improve this subframe () so that it ensures good mechanical properties such as strength, rigidity, acoustics and reinforcement of the body while driving, and absorbs sufficient deformation energy in the event of a crash, and nevertheless can be produced easily and cost-effectively with a low component weight, the side members () have at least one bead () extending in the longitudinal direction of the side members () in the area of the designed buckling point ().

Front axle mounting with crash grooves

A method of making a beam-box crash management system comprises forming a first shell () from a fist sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion () and integrally formed there-with a first low yield strength crash box portion ()proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (). A closing element () is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

A component, especially a control arm for a vehicle, includes a base wall and a passage extending away from said base wall, and in particular, a control arm lug. A method for producing such a component includes shortening a deep-drawn contour which connects one side of the base wall to an inner contour of a passage in the longitudinal direction of the passage by means of upsetting.
