Problems solved by technology

Potentially, such expansion and deformation could damage the form-fit connection of the latch connection or the snap connection
Whether the latch connection will hold up over the life of the enclosure, under all foreseeable load conditions, should theoretically only be determined by a long and complex test, since it is often not possible to lock the enclosure after it has been manufactured. operate internally

Embodiment Construction

[0038] As already mentioned above, the cabinet 1 according to the invention can be configured, for example, as a fuel tank for a motor vehicle with its usual fittings. figure 1The shown enclosure 1 is shown schematically in a very simplified manner. The cabinet 1 is made in one piece of thermoplastic material and can have any contour, in particular the filler pipe and the drain are not shown for simplicity. The box wall 2 of the cabinet 1 comprises two opposing large-surface wall regions 3a and 3b and two opposing small-surface wall regions 3c and 3d.

[0039] The meaning of the term "monolithic" in the present invention does not exclude the fact that the enclosure consists of two complementary shells. The housings may have been completely welded together at the edges of the peripheral flanges so that the enclosure is substantially closed and integrally formed.

[0040] The cabinet 1 according to the invention is preferably obtained by extrusion blow molding, for example by ...

Abstract

The invention relates to a fuel tank for a motor vehicle, which is made up of two shells which are complementary to one another, wherein the shells are supported against one another by at least one strut penetrating the tank (1), connecting opposing wall regions of the tank. The strut is configured as a two- part hollow strut (4), wherein the parts of the hollow strut are latched together via a plug connection and the latching connection is secured by at least one closure body (12) at least partially filling up the cross section of the hollow strut (4) at least level with the latching connection.

Description

technical field [0001] The present invention relates to a casing for a motor vehicle consisting of two shells complementary to each other, in particular to a fuel tank or an auxiliary fluid tank for a motor vehicle, wherein the casing penetrates into the casing and connects the opposite sides of the casing. At least one strut of the wall region supports each other. Background technique [0002] Such an enclosure is disclosed, for example, in DE 10 2006 031 902 A. DE 10 2006 031 902 A relates to a method for manufacturing a hollow box made of thermoplastic material, in which the mold cavity is molded in a multi-part mold by stretching and applying a preform to the inner contour of the mold cavity. web-shaped or sheet-shaped preforms of liquefied plastics material, wherein the method first comprises forming two intermediate products in the form of shells complementary to each other, and in each case connecting struts The parts of the element are fastened to respective inner ...
