Definitions

  • the invention relates to a fuel tank for a motor vehicle with a ' first shell part having a weld seam and with a second shell part covering the first shell part at least in the region of the weld seam, a cavity being arranged between the two shell parts in the region of the weld seam.
  • Such fuel tanks are often used in today's motor vehicles and are known from practice.
  • the shell parts are kept, for example, at a distance to form the cavity.
  • the second shell part also has a weld seam.
  • a helium-sensing probe is then moved along the outside of the weld. In this way, leaks in the weld seams and small cracks in the shell parts can be detected.
  • a disadvantage of the fuel tank having the cavity is that the tightness can only be checked if both shell parts have a leak. Since the helium is also diluted by the air in the cavity in the case of leaks in both shell parts, only particularly large leaks can be detected here.
  • the invention is based on the problem of designing a fuel tank of the type mentioned at the outset in such a way that it enables simple testing of the two shell parts in the region of the cavity for leaks.
  • This problem is solved according to the invention in that one of the shell parts has at least one connection for introducing a test gas into the cavity.
  • the test gas is passed between the shell parts.
  • the area of the fuel tank according to the invention containing the test gas is thus separated from an area which can be traversed by the probe only by a single shell part.
  • the probe can therefore be moved along the inside of the fuel tank and along the outside of the fuel tank. Testing the shell parts for leaks in the area of the cavity is therefore particularly simple.
  • the shell parts can of course also be formed as layers lying one on top of the other and integrally connected to one another and spaced apart from one another exclusively in the area of the weld seam to form the cavity.
  • connection for introducing the test gas could be sealed after the leak test.
  • a later test for the tightness of the fuel tank according to the invention can, however, be carried out simply if the connection for introducing the test gas has means for sealingly fastening a sealing plug.
  • the fuel tank according to the invention is structurally particularly simple if the connection for introducing the test gas has a channel penetrating the outer shell parts. In the worst case, the weld seam can subdivide the cavity, so that a leak in the other partial area would not be detected when the test gas was introduced into one partial area of the hollow space. Leakages of the fuel tank according to the invention can, however, be detected particularly reliably if a connection for introducing the test gas is arranged on each side of the weld seam.
  • an unimpeded flow of the helium into the cavity with the lowest possible consumption can easily be ensured if the distance between the shell parts in the region of the cavity is between 0.1 mm and 10 mm.
  • the cavity has a height of 0.1 to 100 mm in the plane of the shell parts.
  • the invention permits numerous embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below. In a single figure, this shows a section through a partial area of a fuel tank according to the invention which has a weld seam.
  • the fuel tank has an inner shell part 1 and an outer shell part 2.
  • the shell parts 1, 2 are each composed of half-shells 3 - 6 welded together.
  • a cavity 9 is arranged in the area of the weld seams 7, 8 of the shell parts 1, 2.
  • the cavity 9 is connected to the environment via two connections 10, 11 arranged in the outer of the shell parts 2.
  • a test gas such as for example, introduce helium into the cavity 9.
  • a probe (not shown) is guided along the inside and the outside of the fuel tank. The probe detects helium escaping through possible cracks.
  • connections 10, 11 have channels 12, 13 incorporated in the outer shell part 2 and are arranged above and below the weld seams 7, 8. This enables the entire area of the cavity 9 to be reliably detected for leaks, even when the welding expulsion 14, 15 of the opposing welding seams 7, 8 is sealed.
  • two sealing plugs 16, 17 are shown in the drawing. After the fuel tank has been checked for leaks, the sealing plugs 16, 17 are pressed into the channels 12, 13, screwed in or connected to the walls of the channels 12, 13 in a cohesive manner. This closes the connections 10, 11 and seals the cavity 9.

Abstract

L'invention concerne un réservoir de carburant pour un véhicule à moteur. Ce réservoir présente une cavité (9), agencée au niveau de soudures (7, 8) entre deux parties de coque (1, 2), et deux raccords d'arrivée (10, 11) d'un gaz d'essai. Ces raccords (10, 11) sont agencés au-dessus et en dessous des soudures (7, 8). Afin de vérifier l'étanchéité des soudures (7, 8) et des zones des parties de coque (1, 2) adjacentes aux soudures, une sonde détectant l'arrivée du gaz d'essai est déplacée au-dessus de la paroi intérieure et extérieure du réservoir de carburant, ce qui permet de déterminer facilement tout défaut d'étanchéité éventuel.
