Description

[0001] The invention relates to a cross member, in particular for the front end of a motor vehicle, and to a motor vehicle having such a cross member.

[0002] Cross braces are used in the front of motor vehicles to improve the static and dynamic rigidity of the vehicle.

[0003] Cross braces are known, for example, from US Pat. No. 5,411,311 A. The cross brace is a trapezoidal structure in which two arms projecting from a base toward the spring domes are provided, which are connected to another connecting brace between the spring domes. Connecting elements are attached to the ends of the arms and the connecting brace to connect the arms and the brace to one of the spring domes.

[0004] However, the arms and the connecting strut are made of a bent tube, so the manufacturing effort due to the assembly and connection of the individual parts is relatively high.

[0005] JP 2006 - 111 162 A discloses a cross brace according to the preamble of claim 1.

[0006] DE 10 2011 056 737 A1 discloses a front end structure with a cross member with two arms.

[0007] Therefore, the object of the present invention is to create a cross brace which is relatively simple and inexpensive to construct and manufacture compared to the cross braces in the prior art.

[0008] The problem is solved with the features of claim 1.

[0009] An embodiment of the invention relates to a cross strut with two V-shaped arms, with a first connecting element for connecting the two V-shaped arms at their opposite end regions and for fastening the cross strut, in particular in the front end of a motor vehicle, wherein a second or third connecting element is further provided at the distal end regions of the arms, which is connected to the respective arm and serves to connect the cross strut, wherein the arms and the connecting elements are formed as extruded profiles and / or sheet metal formed parts.

[0010] It is advantageous to provide a strut between the arms in the area of ​​the first connecting element. This strut connects the arms in the area of ​​the first connecting element and reinforces the cross strut accordingly.

[0011] It is also advantageous if the first connecting element connects the opposite end regions of the arms and, if applicable, the one strut. This allows the V-shaped arrangement of the arms to be connected by means of a first connecting element, for example, by welding or a form-fitting connection.

[0012] It is particularly useful if the arms, the strut, and the first connecting element are made as extruded profiles. This allows for simpler manufacturing of the components.

[0013] It is also advantageous if the second and / or third connecting elements are manufactured as formed sheet metal parts. This ensures that the second and third connecting elements can be manufactured cost-effectively and can be easily adapted to the vehicle areas to be connected.

[0014] It is also advantageous if the arms, the strut and / or the first, second and / or third connecting element are made of metal, in particular aluminum.

[0015] The invention is explained in detail below using an exemplary embodiment with reference to the drawing. The drawing shows: Fig. 1 a view of a cross brace according to the invention, Fig. 2 a view of the cross brace in an exploded view, Fig. 3 a view of the cross member when installed in the front of the vehicle, and Fig. 4 a cut according to Fig. 3 along line AA.

[0016] The Fig. 1 shows a cross strut 1, as it can be arranged in a motor vehicle between a cowl or a cross member and the two spring strut domes.

[0017] The cross brace 1 is formed with two V-shaped arms 2, 3 arranged at an obtuse angle α to each other. The angle α is more than 90° and less than 180°, such as approximately 120° to 150°. In the area where the opposite ends of the arms 2, 3 approach each other, a connecting element 4 is provided, which connects the two arms 2, 3 to each other. The connecting element 4 has a flange plate 5, which serves for attachment to the cowl or the cross member.

[0018] A strut 6 is also optionally provided between the two arms 2, 3 in the area of ​​the connecting element, which connects the two arms 2, 3 to each other and is also connected to the connecting element 4. For this purpose, the connecting element has a tab 7, which rests on the strut 6.

[0019] A second and third connecting element 10, 11 are arranged at the distal end regions 8, 9 of the arms 2, 3, respectively.

[0020] The second and third connecting elements 10, 11 are connected to the respective arm 2, 3 and serve to connect the cross strut 1 to a respective spring strut dome, for example in the front end of a motor vehicle.

[0021] The arms, the strut, and / or the connecting elements are advantageously designed as extruded profiles and / or formed sheet metal parts. For this purpose, the extruded profiles and / or formed sheet metal parts are made of metal, such as, in particular, aluminum or an aluminum alloy.

[0022] The Fig. Figure 2 shows the cross strut 1 in an exploded view. It can be seen that the first connecting element 4 has chambers 12 separated from each other by struts 13. This provides the first connecting element 4 with additional rigidity. The second and third connecting elements 10, 11 are provided with plate-like end regions 14, by means of which they can be connected to a strut dome. These have connection or screw openings 15 for attachment to the respective strut dome. They also have guide tracks 16 for receiving the respective arm 2, 3. These are formed by two adjacent raised edges.

[0023] The arms 2, 3 and the strut 6 are advantageously designed as U-profiles.

[0024] The components are preferably joined together by welding, such as MIG welding or laser welding or similar.

[0025] The Fig. 3 shows the arrangement of the cross strut 1 between the cowl 17 and the strut dome 18. The first connecting element 4 is connected to the cowl 17 and the second and third connecting elements 10, 11 are connected to the respective strut dome 18.

[0026] The Fig. 4 shows the section AA of the Fig. 3. It can be seen that the cowl 17 is designed as a multi-layer element to which the connecting element 4 is fastened by means of a connecting means 19, such as plugged or screwed.
