Problems solved by technology

[0003] When joining by resistance spot welding, design engineering may result in multi-sheet layers that are no longer weldable
In particular, the multi-piece connection of thin sheets to thicker reinforcements poses difficulties for resistance spot welding
However, in order to be able to make the connection, one or more sheets must be indented, with the result that the vehicle structure is locally weakened
[0004] In addition, alternative laser welding or laser brazing requires a high level of investment
[0005] In addition, when using thermal joining methods, it is not easy to join different materials, such as, for example, aluminum to steel, or to suitable plastics, such as carbon fiber reinforced plastic (CFRP) materials.

Embodiment Construction

[0052] The side view of the body 1 is in the accompanying drawings figure 1 explained in.

[0053] The present invention first relates to the figure 2 The connections of the individual body parts shown in the conventional manner are arranged in the region of the roof channel 8 and in the region of the connection part 2 in which the roof part 3 is connected to the roof frame 4 .

[0054] According to as image 3 and 4 The first exemplary embodiment of the present invention is shown in order to improve the figure 2 The connection point 2. The roof frame 4 here comprises an inner part 5 , a reinforcement part 6 and a side part 7 . The side part 7 has, on the side facing the roof part 3 , a raised beading flange 9 extending over the entire length of the connection point 2 . The roof part 3 has offset roof flanges 10 on adjacent edges.

[0055] The roof part 3 is on the roof frame 4, such as image 3 The direction of the indicated arrow 11 is offset to directly in front o...

Abstract

The present invention relates to a method for producing a vehicle body with a roof part, lateral roof frame parts, a roof channel provided between said components on each side of the roof, and also front and rear roof-structure transverse parts, and aims to obtain a simpler and more cost-effective connection of the roof part to the adjacent components. The roof part and the lateral roof frame parts are fixedly connected to one another at least along the respective roof channel by beading / seaming. The same also applies to the connection of the roof part to the front and rear roof-structure transverse parts. The beading / seaming can additionally be combined with an adhesive or an adhesive tape.

Description

technical field [0001] The invention relates to a method for producing a vehicle body having a roof part, a transverse roof frame part, a roof channel provided between two parts on each side of said roof, and front and rear roof structure transverse parts . Background technique [0002] In the construction of the body shell, thermal joining methods such as, for example, resistance spot welding, laser welding or laser brazing are generally used when joining roof parts to corresponding connecting parts. [0003] When joining by resistance spot welding, design engineering can result in multiple layers that are no longer weldable. In particular, the multi-piece connection of thin sheets to thicker reinforcements poses difficulties for resistance spot welding. However, in order to be able to make the connection, one or more sheets have to be indented, with the result that the vehicle structure is locally weakened. [0004] Furthermore, alternative laser welding or laser brazin...
