A bumper arrangement for a motor vehicle, having an upper main crossmember, which is able to be coupled to the motor vehicle by way of crash boxes, and a lower auxiliary crossmember, wherein main crossmember and auxiliary crossmember are coupled to one another by way of vertical struts. The main crossmember and the auxiliary crossmember run so as to be curved about the vertical axis at least in certain portions, wherein main crossmember and auxiliary crossmember have different radii of curvature from one another, and/or in that the auxiliary crossmember is set back with respect to the main crossmember in a motor vehicle longitudinal direction in the direction directed toward the motor vehicle, and/or in that the auxiliary crossmember has a central portion which is offset in relation to the vertical direction.

A method for calibrating a metal profile blank configured as a hollow-chamber profile having at least one solid wall. A pressing tool is closed in a main direction about one end region of an element of the profile blank until surfaces of the pressing tool lie against a pair of surfaces of the profile blank to be calibrated, deforming and bending the at least one end region of the element. The pressing tool is closed in a secondary direction perpendicular to the main direction until surfaces of the pressing tool lie against surfaces of the at least one end region, and wedge-like limbs of a drive element of the pressing tool engage wedge-like dies of the pressing tool. The pressing tool is closed further in the secondary direction, subjecting the profile blank to plastic deformation so as to reduce or eliminate the bending of the end region.

A suspension strut fork that has an upper portion which is constructed in an integral, materially uniform manner in the form of a suspension strut receiving member. Members and fork arms protrude therefrom in an integral, materially uniform manner. A gap is provided between the members. Via this gap, the members can be moved toward each other so that a resilient and/or damper element which is arranged in the suspension strut receiving member is securely clamped.

A chassis control arm includes a single-piece base body with several hollow chambers. The base body includes a plurality of bearing mounts. A first bearing mount is formed by one of the hollow chambers and traverses the base body to define a first bearing axis which extends in extrusion direction. A second bearing mount in a first end portion of the base body defines a second bearing axis in a direction which deviates from the extrusion direction of the hollow profile. A third bearing mount is positioned in a second end portion of the base body. The base body has a center portion which includes the first bearing mount and is arranged between the first and second end portions. The base body has a first leg extending from the first end portion to the center portion, and a second leg extending from the second end portion to the center portion.

A bumper cross member for a motor vehicle is produced from an extruded hollow profile and has a front side forming an impact side, a rear side in opposition to the front side, end zones configured for connection to the motor vehicle, a central zone extending between the end zones and bent toward the impact side, and top and bottom sides connecting the rear side with the front side. Each of the top and bottom sides has a projecting flange which is separated from the rear side by a separation cut configured to end shy of the end zones so that the flanges are connected with the bumper cross member in the end zones.

An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber. Wall portions of the main chamber which are situated between the longitudinal chambers are removed, and the extruded profile is severed into two semifinished parts. Each semifinished part has one cylinder portion and two oppositely situated arm portions which project relative to the cylinder portions. The semifinished parts are subsequently mechanically machined, and one spring strut fork is produced from each semifinished part.

A multi-leg control arm for a wheel suspension in a vehicle, includes first and second control arm legs coupling the multi-leg control arm to an axle carrier, and third and fourth control arm legs coupling the multi-leg control arm to a wheel carrier. The first and/or third control arm leg comprises a first elongated hole, and the second and/or fourth control arm leg comprises a second elongated hole. The first and second elongated holes are aligned with one another and define a movement path of the multi-leg control arm with respect to the axle carrier or the wheel carrier. At least one fastening element penetrates the first and second elongated holes and is adapted to fix the multi-leg control arm with respect to the axle carrier or the wheel carrier in a movement position on the movement path to set a control arm camber or a control arm track.

The disclosure relates to a motor vehicle control arm, like a wishbone, having an integral main body configured in a materially integral manner. A first bearing receptacle is connected to the main body. The main body has a first end portion having a second bearing receptacle, and a second end portion having a third bearing receptacle. The main body comprises a central portion. Said central portion connects the first and the second end portion. The central portion is configured as a cavity profile. The second and the third bearing receptacle are configured integrally and in a materially integral manner from the main body.

Motor vehicle control arm, and method for producing a motor vehicle control arm

A method for producing motor vehicle controls from extruded profiles and a motor vehicle control. A length section of an extruded profile strand is provided and this is either processed by cutting technology and divided into several extrusion profiles or is first divided into several extruded profiles and they are then processed via shear cutting. By means of a mechanical processing of the extrusion profiles, the motor vehicle controls are formed. The length section has a double T-shaped cross-section with a brace and two belts aligned perpendicular to the brace, wherein the end-side of the belts are connected to flanges. During manufacturing, a motor vehicle control is produced with a steering element, which comprises a middle part and two side arms. In the middle part as well as in the side arms, bearing housings are configured.
