Embodiment Construction

[0047] exist figure 1 A body 10 of a motor vehicle is schematically shown in FIG. The vehicle body 10 here has various structures with cavities, such as an A-pillar 11 , a B-pillar 12 , a C-pillar 13 or a wheel arch 14 . Such a structure with a cavity can now be sealed and reinforced by the element 16 .

[0048] exist figure 2 A part of an exemplary structural element 2 is schematically shown in . In this case, the structural element 2 has a cavity 6 which is located between the first region 4 and the second region 5 . The first area 4 can be, for example, a first sheet material, and the second area 5 can be, for example, a second sheet material. here, as in figure 2 As shown in , the sheets can be connected to each other at the joint location. Furthermore, the cavity 6 or the structural element 2 has a longitudinal axis 3 .

[0049] exist image 3 A sealed and reinforced structural element 2 is now shown in . Here, a support part 20 is arranged in the cavity of the...

Abstract

The invention relates to a system for a sealed and reinforced structural element of a motor vehicle comprising: a structural element which has a cavity having a longitudinal axis; a substrate. A firstmaterial for reinforcing the structural element, the first material having a modulus of elasticity of at least 100 MPa; and a second material for sealing the structural element, the second material having a modulus of elasticity of at most 20 Mpa.

Description

technical field [0001] The invention relates to a system of sealed and reinforced structural elements of motor vehicles and an element for sealing and reinforcing structural elements. Background technique [0002] In many cases, the bodies and / or frames of components such as transport devices and moving devices, in particular motor vehicles, have a structure with cavities in order to achieve a lightweight construction. These cavities however cause various problems. Depending on the type of cavity, this cavity must be sealed to prevent the ingress of moisture and dirt that could lead to corrosion of components. Often it is also desirable to reinforce the cavity and thus the assembly, but keep the structure lightweight. It is often also necessary to stabilize the cavity and thus the assembly in order to reduce noise that would otherwise be transmitted along or through the cavity. Many of these cavities also have irregular shapes or narrow dimensions, making it difficult to ...
