Definitions
- the invention relates to a fastening device for components to be arranged in a fuel tank of a motor vehicle with a fastening element.
- Such fastening devices are used, for example, for fastening a delivery unit, a suction jet pump
- the invention is based on the problem of developing a fastening device of the type mentioned at the outset in such a way that it is structurally particularly simple.
- the fastening element is attached to the base part and to the component. has an ordered headboard and that the headboards can be non-positively connected.
- the component provided with the head part can simply be plugged onto the head part on the base part.
- several fastening elements can of course be provided.
- a corresponding number of head parts are to be arranged on the base part only in that area of the wall of the fuel tank in which the components are arranged.
- the fastening device according to the invention is structurally particularly simple.
- the design of the fastening device according to the invention also leads to a particularly simple fuel tank with a large number of components.
- the positive connection is achieved due to the swelling of the component.
- a positive connection is created.
- the fastening device according to the invention can be easily manufactured if at least one of the head parts of the fastening element is sleeve-shaped.
- the other head part of the fastener can also be sleeve-shaped or designed as a bolt.
- Large components, which are fastened to the wall with several fastening elements according to the invention, can also be easily aligned in their intended position by pushing the head part into the base part accordingly.
- Lines such as vent lines or a fuel line are often routed through the wall of the fuel tank.
- the lines are inside the fuel container and connected to a connection arranged in the wall.
- such lines can be easily attached to the connection and connected at the same time if the fastening element has a channel which runs through the head parts of the base part and of the component and if the head parts are connected to one another in a sealing manner.
- the base part can also have a ventilation nipple.
- connection of the head parts is structurally particularly simple if one of the head parts has circumferential edges pointing radially in the direction of the other head part.
- the one head part can be simply plugged onto the other head part and thus fastened positively or with a corresponding design to the area opposite the edges on the base part.
- the components can be easily attached to the wall of the fuel tank and difficult to remove again if the peripheral edges have a chamfer in their areas facing the other component and a shoulder in their areas facing away from the other components exhibit.
- the edges have the shape of a sawtooth profile in cross section.
- the fastening area requires a particularly low structural outlay if part of the circumferential edges is designed to be radially unyielding.
- a channel guided through the fastening element can be easily sealed off from the fuel tank if part of the circumferential edges is designed to be radially flexible.
- the fastening device has a particularly high holding force for the components to be fastened in the fuel tank and a reliable tightness if at least one of the components of the fastening element in its area opposite the other component is made of a material which can swell in conjunction with fuel.
- the plastics polyoxymethylene (POM) or polyamide (PA) are suitable as swellable materials. Due to the plastic properties of creep and swelling as well as the mechanical compression of the head part with the base part, a non-destructive connection can be created.
- Subsequent attachment of a component in the fuel tank is particularly simple according to another advantageous development of the invention if the head parts are attached in one piece to the base part or the component.
- the attachment can be done either by welding, gluing or positive.
- the head parts are preferably riveted.
- the fastening device according to the invention has a particularly high stability if one or both head parts have lateral support webs.
- FIG. 1 shows a sectional view through a fuel tank with components fastened therein
- FIG 2 is a greatly enlarged view of a fastening device according to the invention for a Wall of the fuel tank from Figure 1 guided line,
- Figure 3 is a sectional view through two fastening devices according to the invention in the fuel tank
- a line 4 designed as a corrugated hose is connected to the delivery unit 3, which line is connected to a connection piece 5 arranged on the outside of the wall of the fuel tank 1 is.
- the line 4 can be, for example, a flow line leading to an internal combustion engine (not shown) of the motor vehicle.
- a lever transmitter 6 is attached to the surge pot 2.
- the line 4 and the surge pot 2 are fastened to the inner wall of the fuel tank 1 with fastening elements 7, 8.
- the lever transmitter 6 also has a fastening element 9 for fastening it to the surge pot 2.
- Figure 2 shows the attachment of the line 4 to the wall of the fuel tank 1 of Figure 1 in a sectional view.
- the fuel tank 1 forms the base part.
- the fastening element 7 has a sleeve-shaped head part 10 manufactured in one piece with the wall.
- a head part 11 of the line 4, which is also sleeve-shaped, is inserted into the head part 10.
- the head part 10 and the head part 11 have a continuous channel 12.
- the head part 11 has a plurality of circumferential, radially projecting edges 13 with which it is in the head part 10 is held non-positively during assembly.
- a part of the edges 13 is designed to be rigid by a shape of a sawtooth and forms a fastening area 14 of the fastening element 7.
- the remaining edges 13 are designed to be radially resilient and form a sealing area 15 of the fastening element 7 with a flat support on the head part 10 a sealing ring 16 is arranged in a groove 23 in the head part 11 and the head part 10.
- This sealing ring 16 is not necessary in the case of pressureless lines, such as a return line or a ventilation line.
- FIG. 2 also shows that the head part 10 has lateral support webs 24.
- FIG. 3 shows a sectional view through a partial area of the surge pot 2 from FIG. 1 with one of the fastening elements 8 for fastening it to the wall of the fuel tank 1 and the fastening element 9 for fastening the lever 6.
- the fastening elements 8, 9 each have a sleeve-shaped head part 17, 18 and a bolt-shaped head part 19, 20 pressed into the head part 17, 18.
- the head parts 19, 20 each have peripheral edges 21, 22 with which they get caught in the head part 17, 18.
- By swelling with fuel a high pressure of the head part 19, 20 with the head part 17, 18 can also be ensured. This leads to high holding forces of the fastening element 8, 9.
- the head part 17 of the fastening element 8 for the baffle 2 is made in one piece with the wall of the fuel tank 1, while the head part 18 for the lever transmitter 6 with the
- Swirl pot 2 is riveted.
- the head parts 19, 20 are sleeve-shaped and overlap the head parts 17, 18.
