Abstract: 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.

Abstract: A composite sheet comprising two sheets joined by material closure provides on the one hand high global and local bending stiffness, and on the other hand very good forming behavior and very high load capacity in case of great deformations, as in case of a crash for example. Both sheets of the composite sheet comprise an at least partially structured surface and a smooth surface and both sheets are at least partially joined by material closure via the structured surfaces.

Abstract: A method for producing a composite part is provided. The method includes a first and at least one second part, wherein the first part at least in part is made of a first metal and the second part at least in part is made of another metal that has a lower melting temperature than that of the first metal. Composite parts produced by the method are also provided. The method for producing composite parts which have an improved load-bearing capacity and yet low weight, is achieved by the fact that at least one breakthrough encompassing a breakthrough collar is introduced into the first part and the second part is non-positively and/or positively moulded onto the first part at least in the area of the breakthrough and the breakthrough collar by heating the second part and applying pressure to said second part.

This is resolved in that the modules are connected to one another in a non-detachable manner in a joint zone, such that a sheet of the one module coming into contact in the joint zone on a sheet section of another module, are joined to one another in a joining process, in which at least one of the sheet sections has been cold-formed, with positive and/or non-positive fit, and in that in at least one of the modules an access channel is formed, extending at least in sections along the joint zone and accessible from outside for introduction of a joining tool.

Abstract: The invention relates to a suspension strut top mounting (1) in a body structure of a motor vehicle. The suspension strut top mounting (1) consists of two half-shells (2, 3) which are connected together in a rigid manner on the outer edge thereof (4, 5) and form a cavity (4) therebetween and are placed on top of each other in the support region (7) of the suspension strut top mounting (8). The suspension strut top mounting (1) is integrated into the body structure as a connecting node for adjacent hollow profiles (10, 12) of the body structure such that it reinforces and delivers a positive contribution to the crash behavior of the vehicle structure.

Abstract: A y-shaped gusset structure can be used, for example, in a support frame for vehicles. The gusset structure includes two hollow sections. The first hollow section includes at least one flat side, has been cut through along its circumference except for a web situated in the flat side, and has been bent open around this web. The face of the second hollow section has been inserted into the facing ends of the first hollow section, which facing ends have been created by the process of cutting and bending open, wherein the edge regions of the ends are integrally connected with the first hollow section.

Abstract: The invention relates to a support structure for vehicles, made from a longitudinal member (1) comprising at least two interconnected hollow sections (10, 11). One of the hollow sections continues in the direction of the bumper (5). In the case of a crash with low-speed impact, there is a targeted deformation of the single hollow section (10c), which makes it possible to carry out repairs economically. In the case of a higher-speed impact, the more rigid support structure of the double hollow section for protecting passengers comes into play. Since in this design the impact absorber, which is usually arranged between the longitudinal member and the bumper, can be done without, there is also a reduction in the number of components required, and thus in the overall weight.

Abstract: The invention relates to a method for manufacturing a sectionally reinforced member made of a tubular hollow profile (1) made of metal. For sectional reinforcement of the hollow profile (1), a sleeve (3) made of metal is slid onto the hollow profile (1) and on the entire area of the section to be reinforced is bonded with bonding agent (2), so that the wall of the tubular hollow section (1) and the sleeve (3) as a result of the bonding agent (2) form a bond. In order to facilitate sliding the sleeve (3) onto the hollow profile (1), the sleeve (3) is enlarged by heating, and/or the external dimensions of the hollow section (1) are reduced by cooling. Forming the hollow section (1) comprising the sleeve (3) into a member takes place prior to a finishing additional treatment step for the purpose of curing the bonding agent (2).
