Abstract

An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that extends in a transverse direction of the underbody panel and is arranged between first and second portions of the underbody panel (14). The first and second portions can be folded together via the folding connection (12)and, in the folded state, are substantially parallel to each other to reduce a size of the underbody panel during transport and storage. In this way, the underbody panel configured as a single part isprovided, storage space and transportation volume of the underbody panel can be saved, and the underbody panel is gap-free when installed on a motor vehicle.

Description

technical field

[0001] The invention relates to an underbody panel for a motor vehicle made of lightweight sandwich material and to a method for producing the underbody panel. Background technique

[0002] For aerodynamic reasons, the underbody of the vehicle is intended to be completely closed and without any gaps. This created the necessity to install large underbody panels. For example, US 8 746 782 B2 describes an underbody cover which is separated via a fold line into a front part and a rear part, so that the front and rear covers can be opened and closed independently of each other. Due to the size of the underbody, correspondingly larger components are provided, so storage and transport of the underbody require a lot of space. However, supply containers and corresponding supply areas at the point of assembly are only present to a limited extent due to the component sizes and the variety of variants.

[0003] Therefore, there is always a need to simplify an underbod...

Embodiment Construction

[0034] figure 1 An underbody panel 10 made of lightweight sandwich material for a motor vehicle is shown. The underbody panel 10 has a one-piece configuration and has a continuous fold connection 12 extending in the transverse direction of the underbody panel 10 . The material for the underbody 10 is SymaLite from the company Quadrant.

[0035] The underbody panel 10 has a size of 1380 mm×1300 mm. In order to store and transport a one-piece underbody panel 10 of this size, large load carriers are required which typically protrude beyond the space of a conventional PAG overhead. Furthermore, due to the space conditions here, dedicated spaces are often not possible adjacent to production lines. For this reason, the underbody panel 10 has a fold connection 12 between the first part and the second part, which can be arranged substantially in the center of the underbody panel 10 .

[0036] as in figure 1 As can be seen in FIG. 1 , the first part and the second part can be fold...
