Embodiment Construction

[0036] The fuel tank 1 shown in the figures is substantially made of thermoplastic material and comprises a top 2 and a bottom 3 between which at least one support 4 extends. The support 4 is designed in one piece and welded at its ends to the wall of the top 2 and the wall of the bottom 3 respectively.

[0037] exist figure 1 In the manner shown in the fuel tank 1 , the support is welded to the wall 6 of the top 2 in the region of the recess 5 of the wall 6 of the top 2 and, in the region of the wall 6 of the bottom 3 , The walls are substantially smooth.

[0038] The support 4 is designed as a one-piece solid profile and has ribs 7 extending in the longitudinal direction of the support 4 . The profile comprises a main body 8 made of relatively hard, brittle torsionally rigid plastic.

[0039] At each end, the support has an integrally formed welding surface 9 which may for example be provided in the form of a pad 10 at one end and in the form of a welding flange 11 at the...

Abstract

The invention relates to a fuel tank (1) made from thermoplastic material, having a top (2) and a bottom (3), which are supported upon one another via at least one column-shaped supporting element (4), wherein the supporting element (4) is connected positively and / or materially to a wall (6) of the top (2), on the one hand, and to a wall (6) of the bottom (3), on the other hand, in such a way that it can absorb tensile forces caused by a pressure within the tank, wherein the supporting element (4) is designed as a one-piece solid profile which has a ribbed profile, at least in cross section.

Description

technical field [0001] The invention relates to a fuel tank made of thermoplastic material having a top and a bottom mutually supported by at least one columnar support, wherein the support is connected with the walls of the top on the one hand and with the walls of the bottom on the other hand. This creates a positive or material connection such that it can absorb tensions caused by the internal pressure of the box. Background technique [0002] Such a fuel tank is known, for example, from DE 10 2009 036 911 A1. The fuel tank described in DE 10 2009 036 911 A1 is reinforced by an inner column. To this end, the column is composed of a first part and a second part, each connected to a corresponding housing, one of which has a notch and the other has a locking hook, which when joined together form a tension-resistant Buckle connector. To this end, the two parts have locking surfaces and flexing surfaces, and the locking hook is flexibly movable. [0003] One part of the co...
