摘要:
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.

The invention relates to a carrier structure of a motor vehicle in a spaceframe style, said structure comprising a roof frame (1) provided with a longitudinal member (1a) and a cross member (1b), longitudinal members (2a, 2b) which are arranged on both sides at the level of the vehicle floor and consist of hollow profiled elements, and posts (3, 4, 5) in the form of hollow profiled elements, connecting the longitudinal members (1a, 1b) of the roof frame (1) to the longitudinal members (2a, 2b) on the side of the floor. The inventive carrier structure is characterised in that at least two opposing posts (3, 4, 5) of the member structure, especially the B, C or D posts, are embodied as double plates formed under internal high pressure and welded on the peripheral edge thereof. The peripheral edge forms flanges (3c, 5c) for door and/or window seals, and the respective ends of the posts (3, 4, 5) are embodied as connection regions (31, 51, 32, 52) adapted to the shape of the longitudinal members (2a, 2b) on the side of the floor and the longitudinal members (1a) of the roof frame (1), and used for connection to the same.

The invention relates to a y-shaped gusset structure of a support frame for vehicles as well as a method for its production. The gusset structure comprises two hollow sections (1, 2), of which the first hollow section (1) comprises at least one flat side and along its circumference has been cut through except for a web (1c) situated in the flat side, and has been bent open around this web (1c). The face of the second hollow section (2) has been inserted into the facing ends 1a, 1b) of the first hollow section (1), which facing ends (1a, 1b) have been created by the process of cutting and bending open, wherein the edge regions (1e) of said ends (1a, 1b) are integrally connected with the first hollow section (1).
摘要:
The present invention relates to a floor structure for a motor vehicle with accommodating means for at least two energy storage modules, wherein the accommodating means comprise at least two longitudinal members and at least two cross members. In addition the present invention relates to the use of such a floor structure in a vehicle with an electric and/or internal combustion engine. The technical problem of providing a floor structure that in the event of accidents, in particular side impacts, improves the protection of the batteries in floor structures of vehicles without adversely affecting the weight or the costs, is solved in that the accommodating means have at least one deformation zone with defined deformation behavior between the energy storage modules.
摘要:
A composite material is shown and described in the form of a laminated material made of flat superimposed layers for production of a structural component, in particular for structural components of a motor vehicle, comprising at least one metal layer and at least one fibre-reinforced plastic layer. In order to achieve firstly a reduction in weight and secondly an increase in strength of a structural component made from the composite material, with a reduction in component costs, it is provided that the fibre-reinforced plastic layer has a matrix based on polypropylene, polyethylene, polyamide and/or mixtures thereof.

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 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.

According to the invention, a blank intended for the production of a sheet panel (11) for a bodywork part of automotive bodywork by cold forming has two deformation sections (2, 4), which consist of highly ductile sheet metal and in the course of cold forming are subjected to a high degree of deformation, and a support section (3), which is arranged between the two deformation sections (2,4) and is formed from a rigid material, which is subjected in the course of cold forming only to a small degree of deformation and after forming of the blank (1) provides the side crash support of the respective bodywork part. In particular motor vehicle doors (6) can be made from such a blank (1).
