Definitions
- the invention relates to a fuel tank for storing gas for mounting in a gas-powered vehicle, in particular a commercial vehicle, wherein the fuel tank has an elongated shape, which is cylindrical in the middle region and is completed at both ends with curved pole caps, and a reinforcing layer made of fiber-reinforced plastic, as well as a metallic connecting piece, a so-called boss, on each of the pole caps, and wherein the fuel tank has at least two fastening devices which enclose the fuel tank with the aid of tension straps and are provided for fastening the fuel tank to a support structure.
- the support structure is used to mount the fuel tank on the vehicle frame. If necessary, several fuel tanks can also be attached to a support structure and mounted together as a tank module in the vehicle.
- Gas-powered vehicles for example, have a gas engine or a fuel cell with an electric motor as a drive.
- the gas which can be hydrogen among other things, is stored in the tank under high pressure.
- Typical for such pressure tanks are pressures of over 200 bar, often up to 700 bar or 875 bar. This means that the fuel tank not only has to be gas-tight under this pressure, but also that it needs a high level of mechanical stability.
- the fuel tank must be of sufficient size for commercial vehicles, which is why such fuel tanks are often more than 2 m long. Particularly with such long fuel tanks, securing them securely to the vehicle is a challenging task, since the fuel tanks have a considerable weight and expand in the longitudinal direction of the tank given the appropriate internal pressure.
- Fuel tanks for gas-powered vehicles are known in the prior art. These pressure tanks have a wall that includes an internal liner, for example made of thermoplastic, for sealing purposes, and a reinforcing layer made of fiber-reinforced plastic to create mechanical stability. This is preferred Reinforcement layer wrapped and designed as a CFRP layer.
- CFRP CFRP layer
- the boss has a through hole and a connecting thread. At least one of the two bosses has a tank fitting connected to it when installed in the vehicle, which makes it possible to fill the pressure tank or remove gas in a controlled manner. On the other boss, the passage opening is sealed with a closure or a safety valve is provided there.
- Fuel tanks for gas-powered vehicles are known in the prior art.
- a tank module is described in DE 202007015487 U1.
- the two fuel tanks are each clamped to a support structure at the two ends of the cylindrical middle part using a tension band as a fastening device.
- a tension band wraps around two fuel tanks.
- the tank module is attached to the vehicle frame via the support structure.
- a tank fitting is provided at one end of the fuel tank, through which the tanks are filled and emptied and which contains the necessary safety devices.
- fuel tanks are known that are mounted vertically in the vehicle, as shown, for example, in document US 2019/0255941 A1.
- This offers the advantage that the fuel tanks can be stored behind the driver's cab to save space, especially in commercial vehicles.
- the fuel tanks are attached with a fastening device that attacks the boss.
- a fastening has, among other things, the disadvantages that, on the one hand, it is more complex and, on the other hand, it is very stiff. Vibrations and shocks cannot be compensated for well.
- the object of the invention is to provide a fuel tank with a fastening device that is better for mounting in the vehicle is suitable in that the fuel tank ensures a secure and reliable attachment.
- the fuel tank is characterized in that it has at least one bead in the cylindrical central region on the outside, which is arranged directly next to one of the fastening devices and lies against it and is designed in such a way that the fuel tank is not affected by the tensioning straps, at least in one direction this one fastening device can slip through.
- the one direction is meant to be parallel to the longitudinal direction of the tank.
- the particular advantage of the design according to the invention is that it provides a secure and vibration-damping fastening without the need to tighten the tension straps too much.
- the bead now protects against slipping. This prevents damage to the reinforcing layer caused by tightening straps that are too tight.
- the fuel tank offers clear positioning for mounting the fastening devices.
- the tension straps of the fastening device are designed in particular as simple clamps or as so-called hinge strap clamps.
- a bead is considered to be a local elevation that has a larger circumference than the diameter of the cylindrical central region of the fuel tank. By designing it as a bead, a smaller amount of material is required than, for example, if the entire cylindrical middle part had a larger diameter and then the tension straps are inserted, for example, into a recessed groove to prevent slipping.
- a groove in the reinforcement layer can also reduce the strength of the fuel tank due to notch effects.
- the fact that the bead rests on the fastening device means that no undesirable, safety-relevant movement of the fuel tank is possible through the tensioning straps of the fastening device in a direction parallel to the tank's longitudinal direction t.
- acceleration forces such as those that occur during braking, by vibrations or by longitudinal expansion due to changes in the internal pressure, at least on one fastening device.
- high forces occur in the tank's longitudinal direction t when the vehicle brakes.
- the bead can preferably be arranged so that it can absorb these forces and prevent the fuel tank from slipping forward. Displacement of the fuel tank causes undesirable forces on the fittings and lines connected to the fuel tank.
- frequent displacements relative to the tension straps can cause damage to the surface of the reinforcing layer.
- this version offers the advantage for assembly that the positioning of the fuel tank relative to the fastening device is clear, thus simplifying the assembly of the connecting lines.
- the bead is arranged directly next to the fastening device, which is arranged closer to the boss, which is intended to accommodate the tank fitting. This means that undesirable stress on the tank fitting and connected lines due to displacement or expansion of the fuel tank can be avoided. And positioning during assembly with regard to the connecting cables is easier. Furthermore, it can be advantageous to provide a second bead in the cylindrical central region on the outside, which is arranged next to the second fastening device, the beads resting against the respective fastening devices and are designed in such a way that the fuel tank does not move in both directions parallel to the longitudinal direction of the tank can slip through the strap(s) of the fastening devices. This is particularly advantageous for horizontal installation in the vehicle.
- the second of the two fastening devices is designed to be so elastic and/or displaceable that the fuel tank can expand in the longitudinal direction of the tank. This can reduce undesirable transverse loading on the upper fastening device.
- the second fastening device is the one further away from the boss intended to receive the tank fitting.
- the bead is annular and surrounds the fuel tank over its entire circumference.
- the bead is designed as one or more ring segments which at least partially surround the fuel tank on its circumference, the ring segment(s) together preferably surrounding at least 20%, particularly preferably at least 40% of the circumference
- the bead is sufficient to prevent slipping in at least one direction.
- the cross-section of the bead can, for example, represent part of a circle or an ellipse, or it can be rectangular.
- the height of the bead is the measure of how far the bead protrudes beyond the diameter of the cylindrical middle part.
- the height of the bead can preferably be at least 10 mm, particularly preferably at least 20 mm. In particular, the height can be at least 2% of the diameter of the fuel tank in the cylindrical central region.
- One of these designs can reliably prevent slipping.
- the extent of the bead in the longitudinal direction of the tank at the connecting surface to the reinforcing layer can preferably be between 20 mm and 80 mm. This ensures sufficient stability and a sufficient connection with the reinforcing layer.
- the bead can be made of a different material than the reinforcing layer.
- a particularly wear-resistant material or a material that is easier to process can be used.
- the bead can be made of metal, plastic, rubber or composite material.
- the bead can also consist of a combination of materials.
- the bead can be attached to the outside of the fuel tank after the reinforcement layer has been manufactured.
- the bead can be glued or vulcanized on.
- it can also be pressed or stretched.
- it can be secured against slipping along the fuel tank surface in a positive connection on the outside of the reinforcing layer.
- the bead can be made from fiber-reinforced plastic as an integral part of the reinforcing layer.
- the bead is therefore manufactured directly during the production of the reinforcing layer.
- the bead is also included is wrapped on the outside before the resin of the reinforcing layer is cured. This ensures a particularly good connection between the bead and the reinforcing layer.
- a metallic element can be provided between the bead and the tension bands of the fastening device. Especially with a bead made of plastic or rubber, this offers a longer lifespan for the bead.
- the metallic element can be, for example, a sheet metal strip that is glued or vulcanized to the side of the bead that comes into contact with the fastening device. Or it can be designed as a metallic coating.
- the fuel tank is designed so that it is intended for vertical mounting in a gas-powered vehicle, in particular a commercial vehicle, with the bead being arranged directly above one of the two fastening devices.
- a gas-powered vehicle in particular a commercial vehicle
- the bead being arranged directly above one of the two fastening devices.
- the fact that the bead is arranged above one fastening device refers to the position when installed in the vehicle.
- the bead is arranged directly above the lower of the two fastening devices.
- the two fastening devices are designed as an upper and a lower fastening device, based on the later position in the assembled state in the vehicle. This will hold the lower part of the fuel tank securely in place.
- the connections and lines for refueling and controlled gas delivery are usually located on the lower boss. These are therefore protected from any forces that may arise when the fuel tank expands in length. Expansion of the fuel tank length occurs when the pressure inside the tank changes during filling or emptying. Further advantageous features of the invention are explained using exemplary embodiments with reference to the drawings. Similar parts are marked with the same reference numbers.

- Fig.2 Representation of a fuel tank according to the invention
- FIG.3a/b/c Detailed representation of various designs of the bead on the fuel tank according to the invention in side view and section Fig.4
- the vehicle 20 is preferably a commercial vehicle, for example a truck as shown here.
- Gas-powered commercial vehicles in particular require large amounts of fuel to achieve an economically viable range.
- the drive can take place, for example, via a fuel cell and electric motor or via a gas engine.
- the fuel can be hydrogen, biogas, methane, ethane, natural gas or a gas mixture.
- the gas is stored under pressure in the fuel tanks 1. A pressure of at least 200 bar, often up to 700 or 875 bar, is usually used.
- the vehicle 20 is shown with a fuel tank module, which usually has a plurality of fuel tanks 1 which are arranged next to one another in the transverse direction Q of the vehicle.
- the fuel tanks 1 are mounted vertically here in the vehicle 20, so that the tank longitudinal direction t is aligned essentially parallel to the height direction H of the vehicle. This offers optimal utilization of the installation space, i.e. maximum possible tank volume, while at the same time improving safety, as the tank fittings are well protected on the underside and are not arranged on the side of the vehicle in a vulnerable area.
- the fuel tanks can also be mounted horizontally next to the vehicle frame.
- the fuel tank 1 has an elongated shape that is rotationally symmetrical to the tank's longitudinal direction t. In the middle area it has a cylindrical shape, which is closed at both ends with curved pole caps that end in a so-called boss 7.
- a safety valve is usually provided on the upper boss 7, which blows off the gas if the temperature or pressure is too high and thus relieves the pressure on the tank, for example in the event of a fire to avoid an explosion.
- the fuel tank 1 can be filled with gas via this and gas can be removed in a controlled manner during operation.
- the tank fittings can optionally include additional safety valves.
- the fuel tank 1 is here equipped with two fastening devices 2,3, which include tension straps, for example simple clamps or so-called hinge strap clamps. There is the upper fastening device 2 and the lower fastening device 3.
- the fuel tank is fastened to the support structure 10 via both fastening devices 2,3. If necessary, more than two fastening devices can also be used, so that, for example, there is still a middle fastening device.
- the support structure 10 also supports the additional fuel tanks and is used to mount the fuel tank module in the vehicle 20. It can be designed, for example, as a steel frame. To protect the fuel tanks 1 against external influences, the protective cover 11 can be provided.
- Fig. 2 shows an embodiment of the fuel tank 1 according to the invention. It comprises two fastening devices 2, 3, one being the upper fastening device 2 and one being the lower fastening device 3. Both are equipped with tension straps that surround the fuel tank around its circumference and are designed as clamps.
- the fastening devices 2.3 each have a base 4.5 to which the tension straps are attached and against which the fuel tank 1 is tensioned.
- the fuel tank 1 can be fastened to the support structure 10.
- This support structure 10 serves to mount the fuel tank 1 in a vehicle.
- the fuel tank 1 with its fastening devices 2,3 is intended for vertical mounting in a vehicle.
- the fuel tank 1 has a bead 6 on the outside, which rests on the lower fastening device 3 and which ensures that the fuel tank 1 does not slip through the tension straps of this fastening device 3. This means it is held securely and does not change position even when it vibrates, which prevents damage to the tank surface.
- the length of the tank changes depending on the internal pressure.
- the bead 6 keeps the position of the fuel tank 1 relative to the lower fastening device 3 fixed. This means that the tank fittings and lines that are usually connected to the lower boss are protected from additional and changing stress caused by the linear expansion of the fuel tank 1.
- the bead 6 can also be provided above the upper fastening device 2, as shown in Fig.5a. This is particularly advantageous if the tank fittings are connected to the upper boss. Since the position of the fuel tank 1 relative to the upper boss remains largely constant as the length expands.
- the fuel tank 1 is mounted horizontally in the vehicle, it can make sense to provide two beads 6, as shown in Fig. 5b.
- the two beads 6 are arranged in such a way that the fuel tank 1 cannot slip through the tensioning straps in both directions along the tank's longitudinal direction t.
- Also according to the invention are further embodiments with several fastening devices which include tensioning straps and in which the bead rests on at least one of the fastening devices.
- Fig. 3a, b, c shows three different versions for the bead 6,6',6" regardless of the position in which the bead 6,6',6" is intended.
- Fig.3a the bead 6 is formed as a ring on the entire circumference of the fuel tank 1.
- the bead 6 ' can only be designed as a ring segment, as shown in Fig. 3b.
- the bead 6', as shown here, is preferably attached to at least 20% of the circumference.
- the bead 6′′ can consist of several ring segments which are arranged on the circumference of the fuel tank 1.
- the bead 6,6',6" can be an integral part of the reinforcing layer or it can be manufactured separately and attached to the outside of the fuel tank 1, as already described above. If it is manufactured separately, the bead 6,6',6" can consist of a different material than the reinforcing layer of the fuel tank 1, for example metal, plastic, rubber or a composite material.
- a metallic element can be provided on the 6,6',6" bead for protection. This metallic element can be, for example, a metal strip or a metallic coating on the side of the bead that comes into contact with the fastening device 3.
- the illustration in Fig. 4 shows an exemplary variant of the fastening device 3.
- the fastening device 3 includes tensioning straps, which are designed here as joint strap clamps, and a base 5 to which the tensioning straps are attached. With the help of this fastening device 3, the fuel tank can be fastened to the support structure 10.
