Definitions

  • the present invention relates to an assembly comprising a front beam of a motor vehicle and two frontal impact absorbers intended to be each fixed between one of the two opposite ends of said front beam and a front end of one of the two side rails.
  • the invention also relates to a front face of the underbody of a motor vehicle comprising an assembly according to the invention.
  • Figure 1 is a perspective view of the front face of the underbody of a motor vehicle of a known type.
  • Figure 2 is a side view of the assembly shown in Figure 1.
  • the front face shown in FIG. 1 comprises a front beam 1 and two front impact absorbers 2, 3 which are each fixed between one of the two opposite ends 1a, 1b of the front beam 1 and a front end of the front beam. one of the two stretchers 4, 5 of the underbody of the vehicle.
  • the beam 1 and the two shock absorbers 2, 3 are aluminum, which reduces their mass and therefore that of the vehicle.
  • the two absorbers each consist of an aluminum hollow body of polygonal constant section.
  • the assembly beam 1 and absorbers 2, 3 must according to the current requirements collect frontal shocks at a vehicle speed equal to 16 km / h without significantly damaging the stretchers 4 and 5, so as to limit the costs of repairing the vehicle. Also known according to the patent FR 2 867 730 a shock absorbing steel beam assembly for a motor vehicle underbody.
  • each of the two shock absorbers is constituted by a hollow body made of sheet steel flared from front to rear, that is to say whose cross section increases from the front to the back.
  • this hollow body has corrugations whose flanks are transverse to the direction of the frontal shocks that the hollow body must absorb.
  • the object of the present invention is to reduce the manufacturing costs of the aluminum assemblies as shown in FIGS. 1 and 2 and to lighten the steel assemblies as described in the French patent above and to increase the performance of these sets.
  • an assembly comprising a front beam of a motor vehicle and two frontal impact absorbers intended to be each fixed between one of the two opposite ends of said front beam and a front end of the front beam.
  • one of the two stretchers, each of these two shock absorbers being constituted by a steel sheet forming a hollow body flared from front to rear, characterized in that said hollow body has corrugations whose flanks extend between the front and the back of said hollow body.
  • said hollow body is constituted by two sheet metal parts in the form of half-shells assembled to one another.
  • each of the two sheet metal parts of the hollow body comprises a portion comprising said corrugations located between two non-corrugated lateral parts.
  • said portion comprising said corrugations comprises between two and four corrugations
  • each of the two non-corrugated lateral portions comprises holes
  • said holes are substantially aligned and the section of these holes increases between the front and the rear of the hollow body constituting each shock absorber.
  • FIG. 3 is a view along the longitudinal axis of a motor vehicle of a beam and shock absorber assembly according to the invention attached to the front of the stretchers,
  • FIG. 4 is a perspective view of the hollow body of a shock absorber of the assembly according to the invention.
  • FIG. 3 shows a front beam assembly 7 and shock absorbers 8 according to the invention fixed at the front of two stretchers 5 of which only one is visible.
  • the front beam 7 is constituted by two pieces 7a, 7b of sheet steel fixed against each other.
  • Each of the two shock absorbers 8 located between the front beam 7 and the plate 6 fixed to the front of the two stretchers 5 is constituted by a steel sheet forming a hollow body flared from the front towards the back, as shown in Figure 4. According to the invention, this hollow body has corrugations 9, 10,
  • FIG. 4 also shows that the hollow body consists of two sheet metal parts 8a, 8b in the form of half-shells assembled to each other along a plane of symmetry of the hollow body forming each of the two shock absorbers 8.
  • this plane of symmetry P (see Figure 3) is located in the plane of the longitudinal and transverse axes X, Y of the vehicle.
  • each of the two sheet metal portions 8a, 8b of the absorber 8 comprises a part comprising the corrugations 9, 10, 1 1 or
  • the top of the corrugations 9, 10, 11 and 12, 13, 14 is located in a plane.
  • Each of the two parts respectively comprising the corrugations 9, 10, 1 1 and 12, 13, 14 comprises, in the example shown in Figure 4, three corrugations.
  • the number of these corrugations can vary for example between two and four.
  • FIG. 4 further shows that the two lateral portions not provided with corrugations each comprise holes 15, 16.
  • These holes 15, 16 are substantially aligned and their section increases between the front and the rear of the hollow body of flared shape constituting each of the two shock absorbers 8.
  • the assembly according to the invention has been compared with an aluminum assembly as shown in FIGS. 1 and 2.
  • the assembly according to the invention has the following advantages:
  • the corrugations formed on the hollow body make it possible to stiffen the hollow body, which makes it possible to use a sheet of steel of relatively small thickness making it possible to lighten each of the absorbers.
  • This lightening is also obtained through the holes 15, 16 formed on the two side portions of the hollow body constituting each of the two absorbers.
