Abstract:
The invention pertains to an add-on part for a vehicle formed as a cast part 1, which is connectable to a vehicle body of the vehicle and for this purpose has a connection part 2 accommodated in cavity 3, in which the joining element or connection part 2 is cast into the cast part during production of the cast part 1.
Abstract:
A rear roof frame of a motor vehicle has a tailgate which is fastened to the roof frame and includes an upper shell and a lower shell which is fitted to the latter. For the design of a rear roof frame, which, in spite of the shell-type construction, provides, in a simple manner and lightweight construction, sufficient torsional and flexural stiffness in order to withstand high mechanical stresses, it is proposed to arrange within the shell structure a hollow profile which leads in each case from the transition region to the lateral roof frame and parallel to the longitudinal extent of the structure, and emerges, at least at the end facing away from the lateral roof frame, in a knee which kinks in the front-end direction of the vehicle. The end of the rear roof frame forms a tubular hollow profile of the lateral roof frame, which is connected to the hollow profile of the rear roof frame.
Abstract:
The invention pertains to a body part 1 for a vehicle formed at least partly from steel cast parts or light metal cast parts 2, at least one metal part or metal material 3 being introduced to the interior of the body or body part 1 so that the body part 1 after conclusion of the casting process has a closed surface structure, the steel cast parts or light metal cast parts 2 being introduced to the casting mold as reinforcement elements that enter into a fixed bond with the solidified melt on conclusion of the casting process.
Abstract:
A front protection bow on a motor vehicle front end is supported by bending-resistant rod profiles on supporting components of the motor vehicle body. The rod profiles of the front protection bow, which together are closed to form a frame and which are largely situated in the overlapping area with the motor vehicle front end comprising a forward front wall and an elastically flexible bumper, extend at least along a predominant portion of the width and the height of the motor vehicle front end. The front wall of the motor vehicle front end has a front end contour which is adapted to the course or curve of the frame and which has at least one section which is embedded in the front wall and in which at least one rod profile of the frame is to be arranged in a sunk manner at least by a partial cross-section. The frame of the front protection bow, when the rod profile is lowered, is arranged to be offset toward the rear with respect to the forward side of the bumper.
Abstract:
A battery carrier for a traction battery of an electric vehicle includes a battery container which is fastened to the vehicle body by holding devices that are clamped around a longitudinally extending sliding tube mounted on the vehicle body. The sliding tube is displaceable relative to the holding devices along a limited distance in the axial direction, so that the battery container can be accelerated relative to the vehicle body in the event of a frontal impact. Energy absorbing devices for controlling the transmission of kinetic energy from the battery container to the vehicle body, while partially consuming energy, may be formed by deformation tubes which are arranged on the sliding tube, and are made, for example, of a fiber composite material.
Abstract:
A load carrier for transporting bulky articles on vehicles, having two beams connected by a cross-strut, the cross-strut being able to secure a load to be carried, has holding tubes that are securable to a rear of a vehicle and extend in a longitudinal direction of the vehicle. The beams are insertable into the holding tubes, and have angled ends. The beams are displaceable by a defined amount in the longitudinal direction in the holding tubes between a rest position in which the beams are under the vehicle and a use position in which the beams project beyond the rear of the vehicle. The beams are fixable in the rest and use positions and mounted so as to each be pivotable about the axis of one of the holding tubes into one of two different end positions. The angled ends of the beams are swivellably articulated on the cross-strut. The beams project beyond the rear of the vehicle and are swivelled upwards with their angled ends when in the use position. In the rest position, the ends of the beams are swivelled into a plane defined by the holding tubes and the beams are inserted into the holding tubes to such an extent that a rear edge of the load carrier is approximately flush with or in front of the rear end of the vehicle.
Abstract:
A bumper for vehicles, with a symmetrically backswept rail, is supported on a skeleton member of the vehicle body via shock absorbing arrangement. To simplify the construction by use of so called foam systems, and at the same time ensuring a high system efficiency, the shock absorbing arrangement is formed by an impact damper extending over the rail length and made of energy absorbing (EA) foam. Arranged in the midle of the bumper is a regenerable shock absorber which works on the positive displacement principle, passes through local clearances in an impact damper and in the rail and is supported on the skeleton member and on a trim shell engaging at a distance round the rail. An impact strip made of EA foam is inserted between the trim shell and the rail.
Abstract:
An A-pillar on a motor vehicle is provided with a windshield flange for the securing of a windshield. The A-pillar is of single-part design in the region of the windshield and a wall region forming the windshield flange bounds a hollow cross section of the A-pillar. The windshield can be integrated indirectly in the A-pillar, which leads to a reduction in viewing angle obscuration.
Abstract:
A supporting frame structure for a motor vehicle is provided with member-type elements and with junction elements connecting the member-type elements, at least one of the junction elements being designed as a cast-steel element, and at least one of the member-type elements is designed as a rolled steel profile.
Abstract:
A process for producing a component with an inner fabric includes layering at least two layers of fabric one on top of the other. A layer of plastic in powder form or sheet form is introduced between respective pairs of neighboring layers of fabric. The plastic has a melting point corresponding to at most the melting point and/or the decomposing temperature of the fabric layers. The fabric layers and plastic layer are heated and pressed at a pressure greater than atmospheric pressure, during which the plastic layer is at least partially melted. After reaching the desired final form, the partially-melted plastic is cooled, thereby bonding the fabric layers to one another. The cooled plastic is arranged between the layers of fabric and, in particular, at least partially between the fibers of the fabric layers.
