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.

The invention relates to a junction structure for connecting two profiles(1, 2), especially in a vehicle support frame. The first profile (1) has at least two planar, parallel sides and the second profile (2) comprises two parallel, opposite girders (3, 4) and at least one strip (5, 6) connecting the girders (3, 4). The girders (3, 4), with their lateral ends, project relative to the strip (5, 6), the projections forming paired, parallel flanges (31, 41, 32, 42). The junction structure is characterized in that the first profile (1) at the location of connection, is provided with a recess (7) into which the second profile (2) is inserted on the front side in such a manner that the parallel sides of the opposite ends (8, 9) of the first profile limiting the recess (7) rest in a form fit against the insides (31a, 41a, 32a, 42a) of the opposite flanges (31, 41, 32, 42) of the second profile (2) and are connected thereto.

The invention relates to a reinforced section for a vehicle supporting frame, said section connecting two pillars (8) of the vehicle supporting frame, in particular the C-pillars or D-pillars at their bases in the form of a transversal wall, whose ends, which are configured as pillar connection zones (6a, 7a), extend onto the pillars (8) by means of rounded corner reinforcements (6, 7). The invention is characterised in that the reinforced section and the corner reinforcements (6, 7) are configured as a one-piece double shell consisting of two blanks (10) produced in an internal high-pressure forming process and welded together around their periphery.

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 −20° C. before the shaping and is shaped at a temperature below −20° 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 −20° C. is carried out in a thermally regulated cooling apparatus.

The invention relates to a bodywork of a motor vehicle comprising side members and a rear axle construction which is connected to the bodywork, the rear axle construction having means for attaching the rear axle construction to the bodywork and having a suspension, and the rear axle construction being configured as a torsion-beam axle or as a multi-link axle. The object to provide a generic bodywork of a motor vehicle with a rear axle construction which allows, in a financially favourable manner, a modular rear axle concept, i.e. the selective use of a torsion-beam axle or of a multi-link axle is achieved in that the bodywork has means for receiving the attachment means of a torsion-beam axle and of a multi-link axle and has means for receiving the attachment means and the suspension of a torsion-beam axle and of a multi-link axle.

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 (6, 14), at least one roof frame cross profile (10) arranged between the roof frame longitudinal profiles (6, 14) and a body pillar (12), wherein in a connecting area (Y) a roof frame longitudinal profile (6; 14), a roof frame cross profile (10) and the body pillar (12) are connected or can be connected together using a mechanical connection. Here the roof frame longitudinal profile (6; 14) comprises a recess (16) in the connecting area (Y), as seen in a longitudinal section of the roof frame longitudinal profile (6; 14), the recess accommodating the roof frame cross profile (10), at least some areas of the circumferential contour of the profile being adapted to match the recess (16). At least parts of the mechanical connection of the roof frame cross profile (10) to the body pillar (12) are disposed in the recess (16) and are designed such that the two opposing side walls of the recess (16) are supported against each another.

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.
