Abstract
A component part for a motor vehicle having a hollow profile portion of a fiber-reinforced plastic and a load introduction element of a metal material. The hollow profile portion and the load introduction element are connected in a common connection portion via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion engage in one another by positive engagement. The end portion of the load introduction element has a spline with teeth extending in longitudinal direction of the common connection portion so that the stiffness of the end portion of the load introduction element reduced in longitudinal direction of the common connection portion.
Claims18
A component part, formed as a chassis link, for a motor vehicle, comprising:
- a hollow profile portion of a fiber-reinforced plastic;
- a load introduction element of a metal material;
- and
- a common connection portion at which the hollow profile portion and the load introduction element are connected to one another via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion mutually engage in one another at least substantially by positive engagement;
- wherein the end portion of the load introduction element has a spline with teeth extending at least substantially in longitudinal direction of the common connection portion so that a stiffness of the end portion of the load introduction element is reduced in longitudinal direction of the common connection portion,
- wherein the hollow profile portion has at least one void formed as a circumferentially closed chamber, and
- wherein the spline has at least five teeth, at least one of which engages in the at least one void of the hollow profile portion.
