Description

The invention relates to a side wall component for a motor vehicle body according to the preamble of patent claim 1.

Sidewall components for motor vehicle bodies are known. In this context, a sidewall component is to be understood as meaning a body portion which, starting from an A pillar of the motor vehicle body, is designed to extend in the direction of a B or C pillar. The pillars of the vehicle body are formed in the form of joints between a roof of the vehicle body and a body base of the vehicle body. The sidewall component comprises at least part of the A-pillar and at least the C-pillar. The A-pillar and the C-pillar are connected in the area of the roof by means of a roof frame. In the region of the body substructure, they are connected to one another at least via a sill of the motor vehicle body, wherein a closed ring structure in the form of a closed frame is formed, which is designed to accommodate at least one door. Particularly in the case of coupes, the sidewall component has a substantial portion of a fender formed in the rear region.

The publication DE 10 2011 010 717 A1 discloses a side wall component for a motor vehicle body, which is constructed in several parts. The side wall member is composed of a front, upper, rear and lower portion, wherein the individual sections are fixedly connected to each other, so that a closed frame is formed. The side wall part is made of high-strength steel or a high-strength steel alloy, wherein the side wall member completely forms an outer skin of the vehicle body.

From the DE 10 2009 030 349 A1 goes out a side wall component for a motor vehicle body, which is integrally formed. The sidewall component has a high material thickness and the columns of the sidewall component are additionally reinforced. The sidewall component is manufactured from sheet metal or fiberglass composite. Furthermore, a reinforcing structure made of an aluminum diecasting alloy is provided. The sidewall member completely forms an outer skin of the vehicle body.

The published patent DE 101 51 684 A1 is a side wall component for a motor vehicle body removed, which is also formed. The sidewall member is initially formed in the form of a closed annular member. The sidewall component has a losbarer subframe, which takes over the function of a front wall pillar of the A-pillar and a sill section during a manufacturing process of the vehicle body and after successful addition of the side wall component with a side wall structure of this subframe is removed.

It is the object of the present invention to provide a low-cost and stable sidewall component for a motor vehicle body.

The object is achieved by a side wall component for a motor vehicle body with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the respective subclaims.

The side wall component according to the invention for a motor vehicle body is designed to form a closed ring shape for receiving or enclosing a vehicle door of the motor vehicle body. It has a bodywork section and a support portion. The support portion is disposed between a first portion end of the body-engaging portion and a second portion end of the body-fitting portion. The body-engaging portion is formed substantially as an outer skin having an outer surface. In a final assembly state, the body-engaging portion is substantially visible and the support portion is covered. In other words, this means that the body-engaging portion is substantially visible from the outside, thus from the environment, whereas the support member is not visible from the outside with the doors closed. An advantage is the fact that on the support member mounting elements can be attached, for example. To attach a fender, which should not be visible for aesthetic and technical reasons. Another essential advantage of the invention is the provision of a stable, handling-resistant outer skin, which is also suitable for the following joining processes for the production of the motor vehicle body and no further process steps, such as the separation of the support member are necessary. Thus, a stable and inexpensive side wall component is realized.

In one embodiment, the sidewall component is a seamless one-piece component. The advantage is the formation of a seamless and jointless outer skin. This results in a reduction in the manufacturing cost of the vehicle body due to a small number to be joined parts. Furthermore, a painting process is simplified because no undercuts, overlaps, seams or joints are formed, which can often only be covered by a multi-layered paint surface.

Advantageously, the Karosserieringabschnitt at least one upper A-pillar portion of the vehicle body, a side roof frame of the vehicle body, formed in a rear portion of the vehicle body further pillar, a predominant portion of a formed in the rear area fender of the vehicle body and a sill.

In a further embodiment, the support portion has a collar formed in the direction of a vehicle transverse axis of the motor vehicle body, wherein the collar is designed to extend in the direction of the vehicle transverse axis, starting from a supporting portion of the support portion facing towards an environment, in the direction of an interior. Due to the collar, the support member has an increase in local bending stiffness and handling stiffness, whereby the support member to bring about overall stability of the side wall component can be relatively narrow and thus save space.

In a further embodiment of the side wall component according to the invention, the support portion is formed in the region of a second A-pillar portion of the motor vehicle body. A sidewall component of the prior art, which is an outer skin of the motor vehicle body, is usually easy to produce, for example, from a steel sheet. However, with lighter materials, such as aluminum, due to their significantly lower elongation at break in the deep-drawing process only low deep drawing degrees are possible before the component irreversibly tears during the forming process.

Particularly difficult is a production of a sill head of the sill, if it is not represented by a painted plastic panel, but is integrally formed with the side wall member. The reason for the very difficult manufacturability of this area is in particular the very high drawing depth measured up to the door entry flange and the simultaneous production of the lower A-pillar section and a transitional area from the sill to the second A-pillar section, which usually has a correspondingly pronounced door entry radius.

One possible solution of the prior art is the separation of the lower A-pillar portion and the portion of the side wall component, which is formed in the region of the lower A-pillar portion. A disadvantage of the separation is, however, on the one hand, the lack of handling after the separation and the lack of inherent rigidity of the side wall component. On the other hand, the jump-off behavior of the sidewall component immediately after the removal of the corresponding portion is a problem in terms of the required dimensional stability, which may no longer be achieved, since the corresponding section ensures the handling and the inherent rigidity of the sidewall component prior to its installation.

The sidewall component according to the invention, whose support portion is formed in the region of the lower A-pillar portion, has the advantage that both the handleability and the inherent rigidity of the sidewall component are retained. The support member does not have to be removed after installation, but can remain in the vehicle body, without significantly more weight and without the manufacturability of the sidewall component is adversely affected.

Particularly advantageously, the support portion is covered with the help of a privacy screen and thus visible to an end user under any circumstances.

The support portion preferably has a pickup point of a reference point system. Reference point systems serve as the basis of tolerance concepts. Tolerances can be maintained with reference points formed on components and thus a dimensional accuracy and, accordingly, a high quality of the overall assembly, in this case the motor vehicle body, can be ensured.

In a further embodiment of the side wall component according to the invention, the support portion is materially connected to a structural component, whereby the connection of the components is secured inexpensively. The cohesive connection can be brought about, for example, in the form of gluing in connection with flow-hole-forming screws, by friction element welding or resistance element welding.

In a further embodiment, a structural component is arranged in the region of the support part, which is a section of the outer skin which is not visible / covered by closed doors. Thus, advantageously and in a simple manner, a lower A-pillar section designed as a structural component can represent the painted bodywork surfaces visible in the lower door panel in the lower A-pillar region.

In a further embodiment, the structural component has openings for receiving a door hinge. Thus, the door hinge can advantageously be connected directly to the formed as a structural component lower A-pillar portion and does not need to be attached to the side wall component. The advantage is that the lower A-pillar portion preferably made of a steel or a Aluminum material and is manufactured as a structural component, that the door hinge of the same material can be joined by welding materially connected to the second A-pillar section. Thus, the joining process of the door hinge is independent of the material of the sidewall component. Likewise, the door hinges can alternatively also be screwed, wherein the side wall member is not clamped to reduce a setting force loss of the screw.

Preferably, the sidewall component is made of a material which has a lower elongation at break than steel. For this purpose, in particular an aluminum material offers. Furthermore, the sidewall component made of an aluminum material has a long service life due to a low tendency to corrosion and a low weight. Due to the low weight of the sidewall component is preferred to use in lightweight construction.

Furthermore, in particular in the case of the sidewall component produced from an aluminum material, a lacquered sill panel can be dispensed with, which saves costs and weight. This is particularly advantageous in the case of a motor vehicle body designed in the form of a so-called coupe, since there is no joint behind the vehicle door, as is the case with additional painted sill covers.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.
