Abstract:
A motor vehicle body includes a support structure made of large-sized partial modules. A roof module has front and rear roof columns placed onto a basic module approximately level with a side wall edge of the body, and the front and rear roof columns of the roof module are connected to one another via a respectively assigned cross member. In order to provide a support structure having a basic module for different roof structures, and to make the support structure very stiff with the roof module, the rear roof columns are connected to each other via a supporting plate of a rear parcel shelf which is stiffened by the assigned cross member.
Abstract:
The invention relates to a motor vehicle body, the support structure (10) of which is composed of large-size partial modules (12, 34, 50, 66), a basic module (12) comprising lateral longitudinal members (15) and a body floor (14) and reaching laterally as far as front wall columns (20), and, when the support structure (10) is assembled, the basic module (12) being connected to a front end module (34) which belongs to the front crumple zone of the motor vehicle and is supported in a crash stable manner on the basic module (12). In order to provide a motor vehicle body, in which the front end module (34) even without a roof construction is fixed in a sufficiently stable manner on the basic module (12), a front end region (36) of the body floor (14) belongs to the front end module (34) and extends rearward over a considerable length region of the basic module (12) between lateral longitudinal member sections (16).
Abstract:
The invention relates to a process for producing a structural element, having at least one cavity-forming half-shell, comprising at least two lips which together form at least one flange, and is distinguished by the fact that at least the lips are provided, at their contact surfaces, with a foam semi-finished product, that the lips are brought together with the aid of a clamping force, that the foam semi-finished product is activated, and the lips are welded together by the activated foam semi-finished product.
Abstract:
The invention concerns a method of producing a hollow profile with flange. To produce a hollow profile with flange in a simple way and to the requirements of the process, on which profile great enlargements and/or dimensional changes in cross section have to be performed with respect to an initial form to achieve the desired final form, it is proposed first of all to roll-form an initial hollow profile with flange from a sheet bar, which flange is formed by ends of the sheet bar lying parallel against each other, the initial hollow profile having a smaller cross-sectional area and a longer flange than the final form of the hollow profile. After that, the initial hollow profile is shaped into the final form of the hollow profile by exerting a fluidic internal high pressure.
Abstract:
An extendable element absorbs impact energy from a baffle and is capable of being moved by a trigger connected to a collision monitoring system. The device is moved in the longitudinal direction out of an initial position, in which it is received essentially in a vehicle side member, into a working position and is capable of being detained in this position. At the same time, the extendable element is guided in a cylinder arranged in the vehicle side member. The cylinder is connected to the vehicle side member via a turn-up profile arrangement which is capable of being transferred out of a position of rest into a deformation position.
Abstract:
A motor vehicle bumper has a crossmember fixed to the body and an impact-confronting collision part. Non-regenerable deformation members are arranged between the collision part and the crossmember, at least in the region of support points, and the impact-confronting collision part is secured to the crossmember via fastening bolts passing through the deformation members. During a deformation of the non-regenerable deformation members, the collision part is displaceable in the longitudinal direction of the vehicle in order to increase the deformation capacity, while preserving the indicator effect of the support points. The collision part is designed as a trim part encasing, at least in the region of the support points, a core consisting of elastically deformable foam. With the exception of the region of the support points, the bumper has a gap on the energy-absorber side. Each fastening bolt is surrounded by a spacer sleeve supported, at one end, on the head underside if the sleeve and, at the other end, on the crossmember fixed to the body.
Abstract:
A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle. The diagonal strut device (1) has a plurality of struts (2) made from a fibre-reinforced plastic composite material, which extend away from a central joint element (3). Each strut (2) can be connected to the undercarriage via it's end facing away from the central joint element (3). For this, a connecting joint element (4) is arranged on the end of each strut (2) facing away from the central joint element (3). The central joint element (3) and the connecting joint elements (4) are formed from a light metal material. The central joint element (3) and the connecting joint elements (4) are then connected to the struts (2) by an at least firmly bonded cast joint. Further, a method for the production of a diagonal strut device (1), as well as a motor vehicle undercarriage, which uses the diagonal strut device (1) for reinforcement.
Abstract:
The present invention relates to a method for joining at least one joint part (3), provided with a through-opening (4), to a hollow profile (1), the joint part (3) being pushed with its through-opening (4) onto the hollow profile (1) up to a joint point (2), and the hollow profile (1) being expanded at least at the joint point (2). In order to improve the durability of the connection between joint part (3) and hollow profile (1), an adhesive (11) is arranged between an inner side (6) of the joint part (3) and an outer side (5) of the hollow profile (1) before the expansion in such a way that the adhesive (11) adheres to the inner side (6) and to the outer side (5) in the region of the joint point (2) after the expansion.
Abstract:
A connection (4) between two parts (2, 3), in particular in a motor vehicle. The two parts (2, 3) are connected to one another in a connection zone (5) via a plastic connection (6) consisting of an injection-molded plastic (8). Additionally, the two parts (2, 3) are connected to one another in the connection zone (5) via an adhesive connection (7) consisting of a cured adhesive (9).
Abstract:
The present invention relates to a hybrid component comprising a sheet-metal metal body and a plastic body injection-molded onto the sheet-metal body. The sheet-metal body is produced by cutting, edging, stamping and/or plastic forming a plate-shaped metal sheet, and has a surface coating on at least one visible side, as well as at least one uncoated cut or stamped edge. The plastic body is injection-molded so that it seals the at least one uncoated or stamped edge of the sheet metal body and stiffens the sheet metal body.
