Definitions

  • the invention relates to a side member, in particular a passenger vehicle, according to the preamble of claim 1.
  • Such a longitudinal beam is known from DE 40 20 363 AI.
  • the invention is concerned with the problem of creating a generic side member in a high-strength and crash-optimized design, which can be assembled from individual, safe, simple and stable tolerance-free profiles. If the individual profiles are made of metal, they should be able to be connected to one another by welding to form longitudinal members of the generic type.
  • the invention is based on the general idea of dividing a reinforcement profile lying inside a closed longitudinal member outer profile in order to simply Manufacturing without any tolerance and being able to connect to the external profiles without tension.
  • composition according to the invention of a generic side member of simply shaped individual profiles, in particular ultra high-strength materials can be used for a rear side member.
  • a manufacturing process for metal sheets to be used hot forming as well as a conventional ion forming technique are possible for the individual profiles, since the structure of the rear side member structure according to the invention is based on a manufacturing and tolerance-oriented approach.
  • the individual profiles made of sheet metal are connected to one another in particular by welding.
  • Fig. 1-3 cross sections of a rear longitudinal beam in three different embodiments, each with a cut through the middle of a motor vehicle rear wheel.
  • x is the longitudinal axis of the vehicle
  • z is the direction in the vertical axis of the vehicle
  • Y is the transverse direction of the vehicle.
  • the longitudinal member composed of the aforementioned profile parts 1 to 4 is welded in the direction of the inside of the vehicle to a floor element 5 of the vehicle.
  • connection of the side member to the vehicle floor element 5 is also a common welded connection.
  • the inner reinforcement profile 2 is composed of two individual profiles 6 and 7, these individual profiles 6, 7 each having the shape of a double angle.
  • Each of these two individual profiles S has a central region 8, as well as angular webs 9 which are angled perpendicularly from it, namely a first angular web 9 leading to the outside and a second second angular web 10 lying exclusively in the interior of the hollow longitudinal beam.
  • the central region 8 is in each case parallel on the respectively assigned U-leg of the U-shaped first outer profile 1.

Abstract

L'invention concerne un longeron, notamment pour voiture particulière, en particulier un longeron arrière, comprenant des profilés porteurs (1, 3, 4) interconnectés en un support creux et formant une surface extérieure fermée, ainsi qu'un profilé de renforcement intérieur (2) situé à l'intérieur de la cavité support et relié aux profilés porteurs (1, 3, 4). L'invention vise à ce que ce longeron, se compose, en tant que pièce à haute résistance et à bon comportement à la collision, d'éléments profilés aisés à produire et exempt de tolérances. A cet effet, un longeron de ce type se caractérise en ce que le profilé de renforcement intérieur (2, 2') se présente sous forme de profilé composé d'au moins deux profilés individuels (6, 7).
