Fahrzeug vehicle
Stand der Technik State of the art
Offenbarung der Erfindung Disclosure of the invention
Druckspeicher, vor allem in mobilen Anwendungen mit technischen Gasen, werden in Fahrzeugen aus physikalischen Gründen und aus Platzgründen in der Regel am Fahrzeugunterboden verbaut. Aufgrund Ihrer Größe werden verschiedene Druckspeicher platzsparend, je nach den räumlichen Gegebenheiten, ggf. weit voneinander entfernt angebracht. Pressure accumulators, especially in mobile applications with technical gases, are usually installed on the vehicle underbody in vehicles for physical reasons and for reasons of space. Due to their size, different pressure accumulators can be installed far away from each other to save space, depending on the spatial conditions.
Um einen sicheren Betrieb eines Druckspeichers sicherzustellen, werden Sicherheitseinrichtungen verwendet, die an oder in einem Druckspeicher angeordnet werden und im Falle eines Defekts oder Unfalls für ein sicheres Abblasen eines Mediums bei Temperatur- und Drucküberschreitungen aus dem Druckspeicher sorgen. In order to ensure safe operation of a pressure accumulator, safety devices are used which are arranged on or in a pressure accumulator and ensure that a medium is safely blown off from the pressure accumulator in the event of a defect or accident if the temperature and pressure are exceeded.
Da Sicherheitseinrichtungen eines Druckspeichers direkt an oder in einem Druckspeicher angebracht sind, entspricht die Zahl der Sicherheitselemente eines Fahrzeugs in der Regel der Anzahl der Druckspeicher. Entsprechend verursachen mehrfach vorhandene Sicherheitseinrichtungen Kosten, erhöhen das Fahrzeuggewicht und verbrauchen Bauraum. Since safety devices of a pressure accumulator are attached directly to or in a pressure accumulator, the number of safety elements in a vehicle generally corresponds to the number of pressure accumulators. Accordingly, multiple existing safety devices cause costs, increase the vehicle weight and consume installation space.

Das Verteilerelement umfasst eine Vielzahl von Anschlüssen für eine Verbindung zu jeweiligen Wasserstofftanks der Vielzahl Wasserstofftanks. Das Verteilerelement umfasst weiterhin eine Funktionseinheit mit Funktionselementen, wobei die Funktionseinheit zwischen der mindestens einen Schnittstelle und der Vielzahl Anschlüsse angeordnet ist.

Dazu kann die Funktionseinheit Funktionselemente, wie bspw. Rückschlagventile oder Schmelzsicherungen umfassen, die in vorgegebenen Bedingungen, wie bspw. bei einer mechanischen oder einer thermischen Belastung, ggf. ein kontrolliertes Ablassen von Wasserstoff ermöglichen. The functional unit of the distributor element of the holding device presented serves as a central safety unit which secures all hydrogen tanks arranged on the holding device, ie in particular prevents an uncontrolled escape of hydrogen from the hydrogen tanks. The Functional unit include functional elements, such as check valves or fuses, which, under predetermined conditions, such as, for example, a mechanical or thermal load, possibly enable a controlled discharge of hydrogen.
Es kann vorgesehen sein, dass die Anschlüsse der vorgestellten Haltevorrichtung derart angeordnet sind, dass mit den Anschlüssen verbundene Wasserstofftanks in einer vorgegebenen Ausrichtung zueinander angeordnet bzw. fixiert werden. Zur Fixierung jeweiliger Wasserstofftanks kann die Haltevorrichtung mindesten ein Widerlager umfassen, das bspw. dazu konfiguriert ist, die jeweiligen Wasserstofftanks an der Haltevorrichtung zu verklemmen. Dazu kann das Widerlager bspw. mittels einer Schraubverbindung lösbar an der Aufnahme der Haltevorrichtung angeordnet sein. It can be provided that the connections of the holding device presented are arranged in such a way that hydrogen tanks connected to the connections are arranged or fixed in a predetermined alignment with respect to one another. To fix the respective hydrogen tanks, the holding device can comprise at least one abutment which is configured, for example, to clamp the respective hydrogen tanks on the holding device. For this purpose, the abutment can be detachably arranged on the receptacle of the holding device, for example by means of a screw connection.
Es kann weiterhin vorgesehen sein, dass die Funktionseinheit und die Vielzahl von Anschlüssen über mindestens eine Fluidleitung verbunden sind. It can furthermore be provided that the functional unit and the multiplicity of connections are connected via at least one fluid line.
Die Anschlüsse können mit der Funktionseinheit der vorgestellten Haltevorrichtung über eine Fluidleitung, wie bspw. eine Bohrung, mit dem Verteilerelement verbunden sein. Selbstverständlich kann die Fluidleitung ganz oder tlw. aus einem separaten fluiddichten Material bestehen und eine Anzahl Verbindungsleitungen, wie bspw. T-Stücke umfassen. Die Verbindungsleitungen können einstückig in eine jeweilige Fluidleitung integriert oder bspw. mittels jeweiliger Schnittstellen an eine jeweilige Fluidleitung gekoppelt werden. Entsprechend kann die Fluidleitung modular erweitert bzw. reduziert werden. The connections can be connected to the functional unit of the holding device presented via a fluid line, such as, for example, a bore, to the distributor element. Of course, the fluid line can consist entirely or partially of a separate fluid-tight material and comprise a number of connecting lines, such as, for example, T-pieces. The connecting lines can be integrated in one piece into a respective fluid line or, for example, coupled to a respective fluid line by means of respective interfaces. Accordingly, the fluid line can be expanded or reduced in a modular manner.
Es kann vorgesehen sein, dass die Funktionseinheit und die Vielzahl von Anschlüssen über eine einzelne Fluidleitung verbunden sind. It can be provided that the functional unit and the multiplicity of connections are connected via a single fluid line.
Mittels einer einzelnen Fluidleitung, die als Sammelleitung zum Verbinden jeweiliger Anschlüsse mit der Funktionseinheit der vorgestellten Haltevorrichtung dient, kann eine besonders kompakte Haltevorrichtung bereitgestellt werden, die besonders wenige potentielle Leckagestellen aufweist. By means of a single fluid line, which serves as a collecting line for connecting the respective connections to the functional unit of the holding device presented, a particularly compact holding device can be provided which has particularly few potential leakage points.
Es kann weiterhin vorgesehen sein, dass die Haltevorrichtung eine Vielzahl Aufnahmemodule umfasst, die jeweils eine Vielzahl Anschlüsse umfassen und durch mindestens eine Fluidverbindung mit der mindestens einen Schnittstelle und der Funktionseinheit lösbar zu verbinden sind. It can further be provided that the holding device comprises a multiplicity of receiving modules, each of which comprises a multiplicity of connections can be detachably connected to the at least one interface and the functional unit by at least one fluid connection.
Mittels lösbar verbindbarer Aufnahmemodule kann die vorgestellte Haltevorrichtung beliebig skaliert werden, indem jeweilige Aufnahmemodule zu der Funktionseinheit hinzugefügt oder von der Funktionseinheit abgekoppelt werden. Entsprechend kann die Haltevorrichtung durch lösbare Aufnahmemodule an eine jeweilige Konstruktion, wie bspw. einen Lastkraftwagen oder einen Kleinwagen, angepasst werden. By means of detachably connectable receiving modules, the holding device presented can be scaled as desired by adding respective receiving modules to the functional unit or decoupling them from the functional unit. Correspondingly, the holding device can be adapted to a particular construction, such as a truck or a small car, by means of detachable receiving modules.
Es kann weiterhin vorgesehen sein, dass die Haltevorrichtung mindestens eine Fahrzeugschnittstelle zur mechanischen Kopplung mit einem Fahrzeug umfasst. It can further be provided that the holding device comprises at least one vehicle interface for mechanical coupling to a vehicle.
Mittels einer Fahrzeugschnittstelle, wie bspw. einem Schnellverschluss oder einer Aufnahme, die zum Eingriff an einer fahrzeugseitigen Gegenaufnahme konfiguriert ist, kann eine einfache und belastungssichere Verbindung zwischen einem Fahrzeug und der vorgestellten Haltevorrichtung erreicht werden. By means of a vehicle interface, such as, for example, a quick-release fastener or a receptacle, which is configured to engage a counter-receptacle on the vehicle, a simple and load-safe connection between a vehicle and the holding device presented can be achieved.
Die Fahrzeugschnittstelle kann bspw. ein Fixationselement zum Fixieren bzw. Verklemmen jeweiliger Wasserstofftanks und ein Verbindungselement zum kraftschlüssigen Sichern an einem jeweiligen Fahrzeug umfassen. The vehicle interface can, for example, comprise a fixation element for fixing or clamping respective hydrogen tanks and a connecting element for frictional securing on a respective vehicle.
Es kann vorgesehen sein, dass die Haltevorrichtung mindestens ein Widerlager zum Fixieren von Wasserstofftanks umfasst. It can be provided that the holding device comprises at least one abutment for fixing hydrogen tanks.
Mittels eines Widerlagers können jeweilige Wasserstofftanks in Zusammenwirkung mit dem Funktionselement in ihren jeweiligen Anschlüssen gesichert werden. Entsprechend kann ein Widerlager lösbar an der Haltevorrichtung angeordnet sein, um einen Wechsel der Wasserstofftanks zu ermöglichen. By means of an abutment, respective hydrogen tanks can be secured in their respective connections in cooperation with the functional element. Correspondingly, an abutment can be detachably arranged on the holding device in order to enable the hydrogen tanks to be changed.
Insbesondere kann vorgesehen sein, dass die Funktionseinheit zumindest die folgenden Funktionselemente umfasst: Mengenbegrenzungsventil, Abluftöffnung, Tankentlüftung, Rückschlagventil, steuerbares Wegeventil, manuell betätigbarer Absperrhahn, Temperaturbegrenzungsventil „TPRD“, Temperatursensor und Drucksensor. In particular, it can be provided that the functional unit comprises at least the following functional elements: quantity limiting valve, exhaust air opening, tank ventilation, non-return valve, controllable directional control valve, manually operable Stopcock, temperature limiting valve "TPRD", temperature sensor and pressure sensor.
Es kann weiterhin vorgesehen sein, dass die mindestens eine Schnittstelle in einem stromlosen Zustand geschlossen ist. It can also be provided that the at least one interface is closed in a currentless state.
Um ein ungewolltes Austreten von Wasserstoff aus jeweiligen Wasserstofftanks zu verhindern, kann vorgesehen sein, dass jeweilige Schnittstellen der vorgestellten Haltevorrichtung lediglich unter Zuführung von elektrischem Strom, bspw. in Form eines Steuerungssignals von einem Steuerungsgerät, zu öffnen sind. Entsprechend bleiben die Schnittstellen ohne ein entsprechendes Steuerungssignal stets geschlossen. Ein derartiges Steuerungssignal kann bspw. von einem Fahrzeug, insbesondere einem Fahrzeugsteuergerät oder von einem Wartungsgerät bereitgestellt werden. In order to prevent unintentional escape of hydrogen from the respective hydrogen tanks, it can be provided that the respective interfaces of the holding device presented are only to be opened with the supply of electrical current, for example in the form of a control signal from a control device. Accordingly, the interfaces always remain closed without a corresponding control signal. Such a control signal can be provided, for example, by a vehicle, in particular a vehicle control device, or by a maintenance device.
Es kann weiterhin vorgesehen sein, dass die Anschlüsse in unterschiedlichen räumlichen Ebenen, insbesondere in mehreren horizontalen und/oder vertikalen Reihen angeordnet sind. It can also be provided that the connections are arranged in different spatial planes, in particular in several horizontal and / or vertical rows.
Durch eine Anordnung von Anschlüssen in mehreren horizontalen und/oder vertikalen Reihen kann eine besonders kompakte Anordnung von Wasserstofftanks erreicht werden, die entsprechend wenig Bauraum an einem Fahrzeug verbraucht. By arranging connections in several horizontal and / or vertical rows, a particularly compact arrangement of hydrogen tanks can be achieved, which accordingly requires little installation space on a vehicle.
Es kann weiterhin vorgesehen sein, dass die Aufnahme mindestens ein Sicherheitselement zum Aufnehmen kinetischer Energie bei einem Unfall umfasst. It can furthermore be provided that the receptacle comprises at least one safety element for absorbing kinetic energy in the event of an accident.
Mittels eines Sicherheitselements zum Aufnehmen kinetischer Energie bei einem Unfall können jeweilige an der Haltevorrichtung angeordnete Wasserstofftanks vor Verformungen geschützt werden. Dazu kann das Sicherheitselement bspw. eine Knautschzone bilden und/oder eine Stützstruktur bilden, die die Wasserstofftanks vor Umgebungseinflüssen schützt. Weiterhin ist die vorgestellte Haltevorrichtung bereits dadurch besonders unfallsicher, dass eine Masse bzw. ein Gewicht der Haltevorrichtung aufgrund des zentralen Versorgungselements besonders niedrig ist und eine Bewegungsenergie der Haltevorrichtung bei einem Unfall entsprechend minimiert wird. By means of a safety element for absorbing kinetic energy in the event of an accident, respective hydrogen tanks arranged on the holding device can be protected from deformation. For this purpose, the security element can, for example, form a crumple zone and / or form a support structure that protects the hydrogen tanks from environmental influences. Furthermore, the holding device presented is particularly accident-proof in that a mass or weight of the holding device is particularly low due to the central supply element and kinetic energy of the holding device is correspondingly minimized in the event of an accident.
Ferner betrifft die vorgestellte Erfindung ein Fahrzeug mit einer möglichen Ausgestaltung der vorgestellten Haltevorrichtung. Furthermore, the presented invention relates to a vehicle with a possible configuration of the presented holding device.

In Fig. 1 ist eine Haltevorrichtung 100 dargestellt. Die Haltevorrichtung 100 umfasst eine Aufnahme 101, an der Schnittstellen 103 und ein Verteilerelement 105 angeordnet sind. In Fig. 1, a holding device 100 is shown. The holding device 100 comprises a receptacle 101 on which interfaces 103 and a distributor element 105 are arranged.
Die Aufnahme 101 umfasst hier eine Rahmenplatte, die eine Verbindung der Haltevorrichtung 100 mit bspw. einem Fahrzeug ermöglicht.

Vorliegend umfasst die Aufnahme 101 ein Widerlager 113, mittels dessen die Wasserstofftanks 111 in den Anschlüssen 109 fixiert werden. Dazu kann das Widerlager 113 bspw. lösbar an der Rahmenplatte fixiert werden und die Wasserstofftanks 111 mittels Niederhaltern 121 in einer vorgegebenen Position relativ zu den Anschlüssen 109 fixieren. In the present case, the receptacle 101 comprises an abutment 113, by means of which the hydrogen tanks 111 are fixed in the connections 109. For this purpose, the abutment 113 can, for example, be releasably fixed on the frame plate and the hydrogen tanks 111 can be fixed in a predetermined position relative to the connections 109 by means of hold-down devices 121.
Die Anschlüsse 109 sind hier bspw. als Gewindebohrungen in dem Verteilerelement 105 ausgestaltet und mit einer Fluidleitung 115 des Verteilerelements 105 verbunden.

Die Fluidleitung 115 ist bspw. als Bohrung in dem Verteilerelement 105 ausgestaltet und sammelt sämtliches aus des Wasserstofftanks austretendes Fluid und leitet dieses zu den Schnittstellen 103. The fluid line 115 is designed, for example, as a bore in the distributor element 105 and collects all of the fluid emerging from the hydrogen tank and guides it to the interfaces 103.
Die Schnittstellen 103 dienen zur Kopplung mit einem Empfängersystem von bspw. einem Fahrzeug und Versorgen das Empfängersystem mit Fluid aus den Wasserstofftanks 111. Zusätzlich oder alternativ können die Schnittstellen 103 zum Befüllen der Wasserstofftanks 111 verwendet werden, indem Fluid aus bspw. einer Tankstelle, durch mindestens eine der Schnittstellen 103 in dem Fluidleitung 115 und schließlich durch die Anschlüsse 109 in die Wasserstofftanks 111 geleitet wird. The interfaces 103 are used for coupling with a receiver system of, for example, a vehicle and supply the receiver system with fluid from the hydrogen tanks 111. Additionally or alternatively, the interfaces 103 can be used to fill the hydrogen tanks 111 by adding fluid from, for example, a gas station, through at least one of the interfaces 103 in the fluid line 115 and finally passed through the connections 109 into the hydrogen tanks 111.
Das Verteilerelement 105 umfasst eine zentrale Funktionseinheit 107, in der Funktionselemente zum Sicherstellen einer Funktion der Wasserstofftanks 111, wie bspw. Sicherheitsventile, Absperrhähne, Filter und/oder Entlüftungen angeordnet sind. Entsprechend werden sämtliche Wasserstofftanks 111 mittels einer zentralen Funktionseinheit 107 gesichert bzw. betrieben. The distributor element 105 comprises a central functional unit 107, in which functional elements for ensuring a function of the hydrogen tanks 111, such as, for example, safety valves, shut-off cocks, filters and / or vents, are arranged. Accordingly, all of the hydrogen tanks 111 are secured or operated by means of a central functional unit 107.
Die Haltevorrichtung 100 ist beliebig skalierbar, wie durch die Trennung 117 angedeutet. Dies bedeutet, dass die Haltevorrichtung 100 zur Aufnahme weiterer Wasserstofftanks 111 oder weniger Wasserstofftanks 111 konfiguriert werden kann. Dazu kann bspw. ein Verbindungsmodul 119 an der Haltevorrichtung 100 angeordnet werden oder von der Haltevorrichtung 100 entfernt werden. The holding device 100 can be scaled as desired, as indicated by the separation 117. This means that the holding device 100 can be configured to accommodate additional hydrogen tanks 111 or fewer hydrogen tanks 111 can. For this purpose, for example, a connection module 119 can be arranged on the holding device 100 or removed from the holding device 100.
