Problems solved by technology

[0003] A disadvantage of the known body parts is that the structural parts can only provide a slight reinforcement to the frame part, since for example all forces on the components screwed to the body part are transmitted directly into the frame part
In addition, the protrusions and ridges prevent the surface coating of the roof rail in the immersion bath

Embodiment Construction

[0023] figure 1 A partial area of ​​a front frame of a motor vehicle is shown with a front axle 2 screwed to a body part 1 designed as a side member. The body part 1 has a pot-shaped frame part 3 made of sheet metal and a structural part 4 made of plastic arranged in the frame part.

[0024] figure 2 show figure 1 Shown is a longitudinal section through a body part 1 with a structural part 4 and a cage nut 5 during assembly. The cage nut 5 is held in a support 6 in a non-rotatable, but slightly movable manner. The support part 6 is positively connected to the structural part 4 by plastic injection molding. In addition, in figure 2 The welding tongs 7 for welding the support part 6 and the frame part 3 are shown in dotted lines. The structural part 4 has openings 8 through which the welding tongs 7 pass and reach the support part 6 .

[0025] image 3 A perspective view of the structural part 4 with the captive nut 5 before being mounted on the frame part 3 is shown. ...

Abstract

A body part of a front frame of a motor vehicle has a structural component of plastic arranged in a frame part. The structural component is connected with a cage nut through material connection. Via the cage nut a front axle is screwed to the body part. A carrying part for holding the cage nut is welded to the frame part for this purpose and connected to the structural component via over molding.

Description

technical field [0001] The invention relates to a body part for a motor vehicle, which has a frame part made of metal and a structural part made of plastic arranged in the frame part, as well as a threaded connections on the frame. Background technique [0002] Such a body part is known, for example, from DE 19858903 A1 as a roof beam and serves for the partial reinforcement of frame parts in the region of the pillars of a motor vehicle body. The structural part is designed as a rigid object and has a plurality of projections by means of which the structural part is supported on the inner wall of the roof rail. The positioning of these rigid objects is achieved by means of ridges which bear on said columns. Furthermore, the rigid piece has a recess in the region of the threaded connection of the frame parts. Therefore, the fixing of the other component takes place only on the frame part. [0003] The known body part has the disadvantage that the structural part can only ...
