The invention relates to a method for producing a shaped sheet-metal part from a panel or a semifinished part made of a material consisting of steel with at least 60 wt. % Fe and a residual austenite content of at least 5%, in which the panel or the semifinished part is at least partially cooled to a temperature below &#x2212;20&#xb0; C. before the shaping and is shaped at a temperature below &#x2212;20&#xb0; C. in a forming tool. The object of providing a method for producing load-compliantly configured components, which on the one hand permits industrial-scale use of low-temperature forming and is configured particularly simply, is achieved by reducing the material temperature of the panel or semifinished part to below &#x2212;20&#xb0; C. is carried out in a thermally regulated cooling apparatus.

Method and device for producing shaped sheet metal parts at a low temperature

A vehicle wheel for motor vehicles may include a wheel-rim ring with an opening, a main member positioned at least partially in the opening of the wheel-rim ring, and a covering shell for at least partially covering the main member. The main member may include an attachment region with receptacles for attaching the main member and the wheel-rim ring to a vehicle. The wheel is configured to have a low weight and an adequate stiffness. Moreover, the wheel also exhibits a secure attachment and no pre-load losses while permitting a high degree of design flexibility. In some examples, the attachment region of the main member is free from the covering shell by way of, for example, a cut-out in the covering shell.

Vehicle wheel and method for producing a vehicle wheel

A method for producing a wheel disk of a vehicle wheel may involve producing the wheel disk produced from a steel blank by hot forming. The blank may be at least partially hardened, preferably press-hardened, during or after the hot forming. The blank may be hot formed using at least one punch and at least one die, and at least one opening may be introduced into the blank using hot trimming means. At least one opening may be introduced during the hot trimming using at least one trimming bolt and an application bolt, wherein the application bolt may have at least one region having a cross-sectional shape that is variable in a longitudinal direction of the application bolt. Using the application bolt, the at least one opening may be calibrated via the variable cross sectional shape.

Process and device for producing hot-formed wheel naves

Disclosed herein is a wheel, in particular for vehicles, such as motor vehicles, with a rim ring having an opening defined there through, and with a main support at least partially arranged in the opening in the rim ring. The wheel, despite having a low weight, provides adequate rigidity and strength and can be produced in a simple manner, while maintaining design flexibility. The main support of the wheel has a plurality of spokes, and a plurality of covering parts for at least partially covering the spokes, wherein the main support and the covering parts support the rim ring.

Wheel having covering parts

A front-end structure includes at least one lower longitudinal member and an absorber which is arranged on an outer side of a vehicle on the at least one lower longitudinal member and, in the event of an impact with a small overlap, provides an energy-absorbing load path into the at least one lower longitudinal member, wherein at least one deformation element is provided which is arranged at least between the absorber and a suspension strut dome and is connected to both thereof in a in a positive, non-positive and/or integrally bonded manner.

Front-end structure

The invention relates to a method for producing a metal structural component, in particular a vehicle structural component, in which a steel part is hot formed and is hardened at least over sections by contact with a tool surface, in which the steel part is during the hardening cooled in at least two partial regions at different cooling rates, so that the partial regions after the hardening differ in their microstructure, wherein the cooling rates differing from one another are produced by sections of the tool surface corresponding to the partial regions of the steel part, which differ from one another as regards their thermal conductivities. The invention also relates to a further method for producing a metal structural component, as well as a tool and a batch furnace.

A body for a motor vehicle and a method for producing a motor vehicle body is provided. Such a body comprises two roof frame longitudinal profiles (), at least one roof frame cross profile () arranged between the roof frame longitudinal profiles () and a body pillar (), wherein in a connecting area (Y) a roof frame longitudinal profile (), a roof frame cross profile () and the body pillar () are connected or can be connected together using a mechanical connection. Here the roof frame longitudinal profile () comprises a recess () in the connecting area (Y), as seen in a longitudinal section of the roof frame longitudinal profile (), the recess accommodating the roof frame cross profile (), at least some areas of the circumferential contour of the profile being adapted to match the recess (). At least parts of the mechanical connection of the roof frame cross profile () to the body pillar () are disposed in the recess () and are designed such that the two opposing side walls of the recess () are supported against each another.

Body for a motor vehicle and method for producing a motor vehicle body

A body of a motor vehicle includes a lateral roof region that has an outer skin, an outer roof frame, and an inner roof frame, wherein the outer roof frame is arranged under the outer skin and the inner roof frame is arranged under the outer roof frame, and the outer skin, the outer roof frame, and the inner roof frame have a common welded flange, by means of which the outer skin and the outer and inner roof frames are connected to one another, and which is configured to receive an adhesive layer for a roof module having a roof module frame. An aspect of the invention is to provide an accident-optimized vehicle body at little expense that prevents a tearing off of the roof module, and is achieved in that the outer roof frame of the body is configured as a locking element for the roof module frame.

Roof construction of a vehicle body

The invention relates to a junction structure for connecting two profiles(), especially in a vehicle support frame. The first profile () has at least two planar, parallel sides and the second profile () comprises two parallel, opposite girders () and at least one strip () connecting the girders (). The girders (), with their lateral ends, project relative to the strip (), the projections forming paired, parallel flanges (). The junction structure is characterized in that the first profile () at the location of connection, is provided with a recess () into which the second profile () is inserted on the front side in such a manner that the parallel sides of the opposite ends () of the first profile limiting the recess () rest in a form fit against the insides () of the opposite flanges () of the second profile () and are connected thereto.
