In a rear end of the vehicle body, an assembly carrier which is arranged in the vehicle transverse direction is inserted between inner body-side side parts of the vehicle rear end. The assembly carrier holds pre-assemblable components and to which assembly carrier is fastened a rear-end trim panel and which assembly carrier is fixedly connected to the two inner side parts by screw devices and forms a stiffening body cross member.
This application claims the priority, under 35 U.S.C. §119, of German application DE 10 2008 036 188.7, filed Aug. 2, 2008; the prior application is herewith incorporated by reference in its entirety.
The invention relates to a vehicle body for a motor vehicle having a vehicle rear end which contains body-side inner side parts, which are arranged so as to be spaced apart from one another, and an outer rear-end trim panel which, with the inner side parts, surrounds a holding space for a rear-mounted engine. The holding space is closed off by a pivotable rear lid which is adjoined by a spoiler which can be retracted and deployed by a setting-out mechanism.
Published, non-prosecuted German patent application DE 10 2006 009 048 A1 discloses an air-guiding device for a vehicle, in which a drive motor for actuating elements of the air-guiding device is arranged on a carrier plate. The carrier plate is formed as a punched metal sheet and is fixed to a luggage compartment cover by screw connections. Furthermore, published, non-prosecuted German patent application DE 103 09 369 A1, corresponding to U.S. Pat. No. 7,481,482, discloses an air-guiding device which is embodied as a module and contains a carrier plate which can be inserted in a cutout of the bodyshell and on which all the movable parts of the air-guiding device, such as for example a hydraulic and electric drive, are supported.
It is accordingly an object of the invention to provide a vehicle body for a motor vehicle that overcomes the above-mentioned disadvantages of the prior art devices of this general type, in which, with structurally simple measures, the vehicle rear end can be reinforced and, at the same time, a pre-assemblable unit for a retractable and deployable spoiler and of further components is obtained.
With the foregoing and other objects in view there is provided, in accordance with the invention, a vehicle body for a motor vehicle. The vehicle body contains a setting out mechanism, a spoiler being retracted and deployed by the setting-out mechanism, a pivotable rear lid, fastening devices, and a vehicle rear end having body-side inner side parts disposed so as to be spaced apart from one another, and an outer rear-end trim panel which, with the body-side inner side parts, surrounds a holding space for a rear-mounted engine. The holding space is closed off by the pivotable rear lid which is adjoined by the spoiler. An assembly carrier is disposed in a vehicle transverse direction and inserted between the two inner body-side side parts of the vehicle rear end. The assembly carrier holding pre-assemblable components and can be connected to the outer rear-end trim panel. The assembly carrier is fixedly connected to the two inner side parts by the fastening devices, and the assembly carrier forms a stiffening body cross member.
The main advantages obtained by the invention are that, first, a stiff rear-end body structure and, second, a holding module for pre-assemblable components can be created by an assembly carrier fastened between inner side parts of the vehicle body. This is achieved according to the invention in that an assembly carrier which is arranged in the vehicle transverse direction is inserted between the two inner body-side side parts of the vehicle rear end, which assembly carrier holds pre-assemblable components and can be connected to the rear-end trim panel and which assembly carrier is fixedly connected to the two inner side parts by screw devices and therefore forms a stiffening body cross member.
The assembly carrier has, on its upper and lower sides and on its end sides, contact surfaces for the pre-assemblable components. The assembly carrier is provided, in each case at its free ends, with bores, which are arranged spaced apart from one another, for fastening devices to the inner side parts of the vehicle body, with in each case one centering or locating pin for positional fixing on the inner side parts being provided between the bores. By this configuration of the assembly carrier and the fixing thereof to the inner body-side side parts of the vehicle body, a pre-assemblable unit is created which simultaneously reinforces the bodyshell at the rear end, since the assembly carrier acts as a strength-increasing body cross member in the strength bond of the bodyshell.
The assembly carrier has a horizontally aligned end-side contact surface which is directed toward the rear-end trim panel and to which a corresponding edge of the rear-end trim panel can be connected by fastening devices. Furthermore, the rear-end trim panel is connected to the assembly carrier over one longitudinal region and is connected, over an adjoining further longitudinal region, to a retaining strip which is arranged on a lamp body for a rear-end lamp, which lamp body is held on the inner side wall parts to which the assembly carrier can also be fastened. By this configuration, the rear-end trim panel can be fixed to the vehicle body in a positionally accurate fashion continuing from the assembly carrier.
The assembly carrier has, on an underside contact surface and in a vehicle longitudinal central plane, a pre-assemblable drive motor with drive shafts, which extend to both sides, for a setting-out mechanism of the spoiler. Furthermore, a pre-assemblable lock for the pivotable rear lid is arranged on the rear side of the assembly carrier on a further contact surface—as viewed in relation to the direction of travel. Furthermore, an actuating element with a Bowden cable for the lock of the rear lid is arranged on an upper-side contact surface of the assembly carrier, close to the free end of the assembly carrier. Furthermore, the pre-assemblable setting-out mechanism for the spoiler is arranged on the assembly carrier at both sides of the vehicle longitudinal central plane, and an activation module for a front closing part—as viewed in relation to the direction of travel F—is additionally provided on one side of the assembly carrier. By this attachment of the individual components to the assembly carrier before installation into the vehicle, the assembly of the components and of the spoiler is simplified. For this purpose, the setting-out mechanism of the spoiler projects partially through openings in the assembly carrier, which setting-out mechanisms are connected to a lower part of the spoiler.
The assembly carrier is preferably composed of a cast aluminum part and is formed, in cross section, with a plurality of steps, and in the central region, the assembly carrier has a plurality of transversely running hollow ribs which are arranged on the upper step or so as to delimit the steps at the edge side. By this configuration, optimum stiffness of the assembly carrier is obtained overall such that, with the inner side parts of the vehicle body, a rigid strength bond is obtained in the rear-end region of the bodyshell. Alternatively, the assembly carrier may also be composed of sheet metal or fiber-reinforced plastic.
Although the invention is illustrated and described herein as embodied in a vehicle body for a motor vehicle, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
