Definitions
- a generic impact beam is known from EP 0 467 829 B1.
- the impact beam there is extruded and designed as a box-shaped, elongated hollow profile.
- the hollow profile has an inner profile wall facing the vehicle interior serving as the inner belt and an opposite outer profile wall serving as the outer belt.
- the two profile walls are connected to each other by transverse walls, which have a comparatively small wall thickness compared to the profile walls.
- the outer belt holes should be provided in the outer belt that lie outside the center of gravity of the carrier. Despite this measure, the security against buckling in the event of an impact is not sufficient.
- the lightweight aspect plays an important role in the strength and rigidity of the support is' not very ho h if it is a carrier of light metal.
- the object is achieved by the features of claim 1.
- the interaction of the hollow profile with a flat fiber-reinforced plastic part bundles the favorable properties in terms of lightweight construction, rigidity and strength of the impact beam.
- the hollow profile provides a high resistance to shear forces due to its extensive closedness for the wearer, while the fiber-reinforced plastic part counteracts the bending moment arising in the wearer due to the impact of the fibers running parallel to the wearer, thus counteracting a high degree of elastic rigidity and strength Bending and forces acting in the axial direction.
- the energy consumption and the achievable unbreakable deformation path are particularly high. Due to the flat box shape, a particularly good connection of the plastic part to the hollow profile is created.
- the invention also makes it possible to form a carrier which, while maintaining rigidity and strength, is considerably narrower than conventional carriers and / or has a smaller wall thickness. As a result, leaner structures can be realized on the vehicle body at a suitable point without having to accept losses in rigidity and strength. In addition, the weight of the carrier and thus the entire body is significantly reduced.
- the area of application of the carrier can be found anywhere on the vehicle where there are only slight curvatures and where loads act on the vehicle in a directed manner.
- the beam can be used as a bumper beam or as part of it, in the middle part of the side roof frame or as a side impact protection. Use as a roof bow to connect the B-pillars is also conceivable.
- the fiber-reinforced plastic part 10 is lamellar and contains in its epoxy resin matrix only unidirectional carbon fibers which extend along the 'plastic part 10.
- the matrix can also be formed from a thermoplastic, which means that the lamellar plastic part 10 can be preformed to conform to the shape.
- Body structure improved. Instead of carbon fibers, aramid fibers or boron fibers, which still exceed the tensile properties of carbon fibers, but are relatively expensive, are also conceivable. This results in a very high elastic rigidity and strength for the impact beam 7 composed of the composite of plastic part 10 and hollow profile 8 - even after flowing. of aluminum in the event of a crash - and an optimal resistance to the axial forces caused by the bending moment of the impact beam 7.
