Definitions

  • the invention relates to a method for attaching a structural reinforcement to a closed or process-related already closed profile, in particular by means of internal high-pressure formed profile.
  • the invention further relates to a closed or process-related already closed profile with a structural reinforcement.
  • Hydroforming profiles are closed profiles with small component tolerances due to the process.
  • the hydroforming profile has to be cut open in order to introduce the reinforcing component through the resulting opening. Subsequently, the reinforcing member must be fixed and the opening to be closed again. This happens because of the one-sided accessibility usually by welding.
  • this object is achieved with a method for attaching a structural reinforcement to a closed or process-related already closed profile, in particular by means of internal high-pressure formed hydroforming profile with the following steps:
  • the hydroforming profile is provided with at least one recess
  • the structure reinforcement is bolted to the profile, wherein the structural reinforcement simultaneously closes the recess of the hydroforming profile.
  • the method described results in short and accurate friction chains and, by avoiding hot joining processes, the good initial tolerances of the starting materials are maintained. Except- In particular in space-critical areas a power flow and load fairer design of the components is made possible. As a result, weight advantages can be achieved. In addition, the method according to the invention can also be carried out in a region which is severely constricted for reasons of space.
  • the object is achieved by a closed or process-related already closed profile, in particular by means of internal high-pressure formed profile with a structural reinforcement, wherein the profile is provided with at least one recess into which the structure reinforcement is introduced, wherein the structural reinforcement with the profile is bolted so that the structural reinforcement closes the recess of the profile.
  • Figure 1 is a produced by the novel process
  • FIGS. 5 to 7 show details of the component according to FIG. 1, the component serving to attach a head-up display and a footrest assembly.
  • a component produced by the method according to the invention is shown in various representations - partially in section.
  • the component consists of a closed or process-related already closed profile 1, in particular profile 1 formed by internal high-pressure and a structural reinforcement 2 introduced into the profile 1.
  • the profile 1 is provided with at least one, in the illustrated embodiment with two recesses 3 at the point at which the structural reinforcement is to be introduced.
  • the structural reinforcement 2 is preferably produced in an aluminum or plastic casting process. It consists in the illustrated embodiment of a frame-like element which is adapted on one side to the shape of the profile 1 and this at least partially encloses.
  • the structural reinforcement 2 has a profile 4 complementary surface 4, from which two strut-like dome 5 extend.
  • the structural reinforcement 2 is inserted into the profile 1 such that the strut-like domes 5 penetrate the recesses 3 and extend as far as an end wall of the profile 1 opposite the recesses 3. In this position, the complementary surface 4 covers the recesses 3 and closes them.
  • the strut-like dome 5 are fastened to the end wall with screws 6, resulting in a fixation of the structure reinforcement 2 in the x direction.
  • the profile 1 at least partially enclosing complementary surface 4 also attached to the profile 1 by means of screws 7.
  • the structural reinforcement 2 in particular in the region of the profile 1 at least partially enclosing complementary surface 4 are glued to the profile 1.
  • the component according to the invention serves for mounting or receiving a head-up display 8 and a foot pedal mechanism 9.

Abstract

La présente invention concerne un procédé pour appliquer un renfort structurel (2) sur un profilé fermé ou déjà fermé en raison du processus (1), en particulier un profilé transformé par formage sous haute pression intérieure. Ce procédé consiste à ménager au moins un évidement (3) dans le profilé (1), à introduire le renfort structurel (2) dans cet évidement (3) du profilé (1), puis à visser le renfort structurel (2) au profilé (1), le renfort structurel (2) fermant alors en même temps l'évidement (3) du profilé (1). Cette invention concerne également un profilé fermé ou déjà fermé en raison du processus (1), en particulier un profilé transformé par formage sous haute pression intérieure qui comprend un renfort structurel (2). Ce profilé (1) est pourvu d'au moins un évidement (3) dans lequel le renfort structurel (2) est introduit. Le renfort structurel (2) est vissé au profilé (1) de manière à fermer l'évidement (3) du profilé (1). On obtient ainsi un procédé pour appliquer un renfort structurel (2) sur un profilé fermé ou déjà fermé en raison du processus et un profilé fermé ou déjà fermé en raison du processus présentant un renfort structurel qui sont simples et économiques à réaliser et qui n'entraînent pas d'irrégularités des composants liées à la chaleur.
