DE3106128A1 - Single-component tailgate element for use in the construction of vehicles - Google Patents

Abstract

The present innovation relates to the design of a single-component tailgate element which is suitable for the construction of vehicles and is characterised by its favourable weight accompanied by a high degree of stability and by low production and processing costs. These advantages are to be achieved by this innovation since reinforcements, struts, surrounds and connection profiles which would have to be attached additionally can be dispensed with. The single-component tailgate element is designed in such a way that the required stability and the connection facilities are provided by the shape alone. By virtue of the special shape of the single-component tailgate element it is possible to use a plurality of identical or almost identical elements to produce a self-supporting box structure which is composed of three or four components and is enclosed on four or three sides.

Description

One-piece side wall element for use in vehicle construction

The area of application of the present innovation relates to the Formation of a side wall element which is suitable for vehicle construction and due to its low weight with high stability and low manufacturing and processing costs.

These advantages are to be achieved by the innovation, as on in addition No reinforcements, struts, borders and connection profiles to be attached can be because it is a one-piece board edge element in which The shape alone provides the necessary stability and connection options given are.

In vehicle construction, especially in trailers, drop sides are known, which consist of several, individual boards or wooden panels.

In order to achieve stability and rigidity, these are and / or U-profiles and also other struts and connection profiles to be found. These costly and labor-intensive measures are in these constructions necessary, especially for trailers with rigid side walls, as the rigid side walls usually have to fulfill a supporting function at the same time.

Furthermore, side walls are known that are made of metal profiles or Metal sheets are made. These also consist of several, different and individual parts, those of the stiffening, the connection or termination or the connection with other components.

Experience has shown that elements that are put together from several parts, less favorable in terms of cost, since these individual parts are matched to one another and must be connected to each other, which means that additional operations such as drilling, screwing, riveting and / or welding are required. Further costs fall through necessary Tools such as screws, rivets and electrodes etc.

The advantage of the construction according to the invention, the one-piece side wall element, exists opposite be; In the special form of the one-piece construction Elements and in the special composition several of the same or almost the same one-piece side wall elements, to an all-sided or three-sided, partially self-supporting box structure. This makes it possible to have a light and yet to create stable front wall element that also in terms of manufacturing and Processing costs are much cheaper than conventional designs.

The innovation therefore provides a one-piece board wall element that made of sheet metal, preferably steel or light metal. the Shaping can be done by trimming, bending or pressing, but it can can also be a drawn profile. The required strength, in terms of the deflection and the twist, is determined by the respective material strength and the material thickness to be selected essentially through the dimensioning of the reached individual leg lengths.

The drawing shows, for example, embodiments of the subject matter of the invention shown: Fig.1 shows a cross-section of the one-piece drop side element.

The height of the side wall represents the distance a, which legs b and c form here, for example, a curved U-shaped stiffening profile and the legs d, is intended for the connection of the base plate.

For example, Fig.2 shows an embodiment in which the so-called Reinforcement profile was extended by a leg, creating a rectangular or square, tubular profiling is created in this area. This tube-like Profiling can also be round, oval, pitch circle-like, triangular, polygonal, closed or be open.

For example, Figure 3 shows one processing option of three one-piece side wall elements that form a rigid box structure closed on three sides, as it is used, for example, in trailers with a foldable drop side can.

Fig. 4 shows, for example, a corner connection, which for reasons of stability was preferably formed double-overlapping by the aforementioned side wall elements notched accordingly and at an angle of 90 ° to the previously mentioned folds were folded at right angles to create the connection connections for the corner connection to obtain.

Fig. 5 + 6 shows the section A - B and C - D, which makes a special one Connection possibility for the base plate emerges.

Figure 7 shows, for example, an embodiment of the one-piece drop side element, as it can be used for double-walled, foldable drop sides. As can be seen is it the same profile, corresponding to the innovation, as shown in Fig. 1, however, the leg d was provided with a further bow, which corresponds to the distance and is used to attach the second one-piece element. The second side wall element , which is used in the double-walled design, corresponds to Figure 7 and only differs from the first drop side element in that it is different Length of the distance a, this distance corresponds approximately to the length of the opposite set profile.

Figure 8, for example, shows a foldable drop side made of two one-piece parts Side wall elements, as provided in the new Fig..
