Der Erfindung liegt die Aufgabe zugrunde, eine Druckspeichereinrichtung, bereitzustellen, mit der Herstellkosten, Montagezeiten und Variantenanzahl reduziert werden können und die eine Funktionsintegration ermöglicht.The invention has for its object to provide a pressure storage device, with the manufacturing costs, assembly times and number of variants can be reduced and allows a functional integration.
Die Lösung der Aufgabe erfolgt mit einer Druckspeichereinrichtung für eine Kraftstoffversorgungseinrichtung einer Kraftfahrzeug-Brennkraftmaschine aufweisend eine Druckspeicherwand aus Kunststoff mit einem Kraftstoffeinlass und wenigstens einem Kraftstoffauslass, wobei die Druckspeichereinrichtung eine Druckmessöffnung und eine an der Druckmessöffnung angeordnete Drucksensoreinrichtung aufweist, wobei die Druckmessöffnung einen stufig profilierten umlaufenden Rand aufweist, wobei die Drucksensoreinrichtung einen Sensorabschnitt mit einem Sensorelement aufweist, das in einem an das Sensorelement angespritzten Sensorgehäuse aus Kunststoff angeordnet ist, wobei der Sensorabschnitt einen radial innenseitig in die Druckmessöffnung eingreifenden inneren Ringabschnitt und einen die Druckmessöffnung radial außenseitig umgreifenden äußeren Ringabschnitt aufweist, und wobei das Sensorgehäuse an der Druckmessöffnung mit der Druckspeicherwand durch Reibschweißen verbunden ist. Damit kann die Drucksensoreinrichtung als Baugruppe vorgefertigt werden. Die Drucksensoreinrichtung weist einen besonders kompakten Aufbau auf. Es kann eine Drucksensoreinrichtung für unterschiedliche Druckspeicher verwendet werden. Die Funktion der Bestimmung des Drucks eines in dem Druckspeicher vorhandenen Kraftstoffs kann in die Druckspeichereinrichtung integriert werden. Eine Wärmeeinflusszone ist besondere klein. In einer Fügezone kann eine Bildung von Schmelze vermieden werden. Die Materialeigenschaften im Verbindungsbereich werden damit gegenüber den Eigenschaften der Kunststoffdruckspeicherwand und des Kunststoffsensorgehäuses, wenn überhaupt, nur minimal verändert. Eine Festigkeit wird nicht negativ beeinflusst. Es können eine Vielzahl von Kunststoffen miteinander verschweißt werden.The object is achieved with an accumulator device for a fuel supply device of a motor vehicle internal combustion engine having a pressure accumulator wall made of plastic with a fuel inlet and at least one fuel outlet, wherein the accumulator device has a pressure measuring port and a arranged at the pressure measuring port pressure sensor device, wherein the pressure measuring port a stepped profiled peripheral edge wherein the pressure sensor device has a sensor section with a sensor element, which is arranged in a molded onto the sensor element sensor housing made of plastic, wherein the sensor portion has a radially inner side engaging in the pressure measuring opening inner ring portion and the pressure measuring opening radially outside embracing outer ring portion, and wherein the sensor housing is connected at the pressure measuring opening with the accumulator wall by friction welding. Thus, the pressure sensor device can be prefabricated as an assembly. The pressure sensor device has a particularly compact design. It can be used a pressure sensor device for different pressure accumulator. The function of determining the pressure of a fuel present in the pressure accumulator can be integrated into the pressure accumulator device. A heat affected zone is particularly small. In a joining zone, a formation of melt can be avoided. The material properties in the connection region are thus minimally changed, if at all, with respect to the properties of the plastic pressure storage wall and of the plastic sensor housing. Strength is not negatively affected. It can be a variety of plastics welded together.
Die Drucksensoreinrichtung kann einen Anschlussabschnitt mit Steckverbindern aufweisen, die in einem mit dem Sensorgehäuse verbundenen Anschlussgehäuse angeordnet sind. Damit sind auch die Steckverbinder in die Druckspeichereinrichtung integriert.The pressure sensor device may have a connection section with connectors which are connected in one to the sensor housing Connection housing are arranged. Thus, the connectors are integrated into the pressure storage device.
Die Druckspeicherwand kann eine zylinderartige Form mit Grundflächenabschnitt und Deckflächenabschnitt aufweisen und die Drucksensoreinrichtung kann an dem Grundflächenabschnitt oder an dem Deckflächenabschnitt angeordnet sein. Damit kann ein gesonderter Anschlussstutzen für die Druckmessöffnung entfallen. Die Druckspeichereinrichtung kann besonders einfach hergestellt werden. Die Druckspeichereinrichtung weist einen besonders bauraumoptimierten Aufbau auf. Die Druckspeichereinrichtung weist eine besonders druckstabile Konstruktion auf. Die Druckmessöffnung kann in ihren Abmessungen zumindest annähernd dem Grundflächenabschnitt oder dem Deckflächenabschnitt entsprechen. Damit kann ein Wandabschnitt zur Bildung des Grundflächenabschnitts oder des Deckflächenabschnitts zumindest teilweise entfallen.The pressure accumulator wall may have a cylinder-like shape with base surface portion and top surface portion, and the pressure sensor device may be disposed on the base surface portion or on the top surface portion. This can be dispensed with a separate connection piece for the pressure measuring opening. The pressure storage device can be produced particularly easily. The pressure storage device has a particularly space-optimized structure. The pressure storage device has a particularly pressure-stable construction. The pressure measuring opening may correspond in size at least approximately to the base surface portion or the top surface portion. In this way, a wall section for forming the base surface section or the cover surface section can be at least partially eliminated.
Das Sensorgehäuse kann mit der Druckspeicherwand durch Rotationsreibschweißen, Ultraschallschweißen, Orbitalreibschweißen oder Rührreibschweißen verbunden sein. Insbesondere das Ultraschallschweißen eignet sich gut zum Fügen von thermoplastischen Kunststoffen. Es werden sehr geringe Schweißzeiten und eine hohe Wirtschaftlichkeit erreicht.The sensor housing may be connected to the accumulator wall by rotary friction welding, ultrasonic welding, orbital friction welding or friction stir welding. In particular, the ultrasonic welding is well suited for joining thermoplastic materials. Very low welding times and high efficiency are achieved.
Die Drucksensoreinrichtung kann als Baugruppe vorgefertigt werden. Die Drucksensoreinrichtung weist einen besonders kompakten Aufbau auf. Es kann eine Drucksensoreinrichtung für unterschiedliche Druckspeicher verwendet werden. Das Sensorelement kann gegebenenfalls zusammen mit weiteren elektronischen Bauelementen und/oder Leitungen und/oder einer Platine in dem an das Sensorelement angespritzten Sensorgehäuse aus Kunststoff angeordnet sein. Das Sensorelement und/oder die weiteren elektronischen Bauelemente und/oder die Leitungen und/oder die Platine ist vor unerwünschtem Einfluss von Medien, wie Kraftstoff, geschützt.The pressure sensor device can be prefabricated as an assembly. The pressure sensor device has a particularly compact design. It can be used a pressure sensor device for different pressure accumulator. If appropriate, the sensor element may be arranged together with further electronic components and / or lines and / or a circuit board in the plastic sensor housing molded onto the sensor element. The sensor element and / or the further electronic components and / or the lines and / or the board is protected against undesired influence of media, such as fuel.
Zur Herstellung einer derartigen Druckspeichereinrichtung wird die zunächst baulich gesonderte Drucksensoreinrichtung mit ihrem Sensorgehäuse an der Druckmessöffnung mit der Druckspeicherwand durch Reibschweißen, insbesondere durch Rotationsreibschweißen, Ultraschallschweißen, Orbitalreibschweißen oder Rührreibschweißen, verbunden. Insbesondere das Ultraschallschweißen eignet sich gut zum Fügen von thermoplastischen Kunststoffen. Es werden sehr geringe Schweißzeiten und eine hohe Wirtschaftlichkeit erreicht.To produce such a pressure storage device, the initially structurally separate pressure sensor device is connected with its sensor housing at the pressure measuring opening to the pressure storage wall by friction welding, in particular by rotary friction welding, ultrasonic welding, orbital friction welding or friction stir welding. In particular, the ultrasonic welding is well suited for joining thermoplastic materials. Very low welding times and high efficiency are achieved.
Zusammenfassend und mit anderen Worten dargestellt ergibt sich somit durch die Erfindung ein kunststoffumspritzter Drucksensor als verschweißtes Bauteil, der nicht mehr aus Edelstahl ausgeführt ist oder zumindest einen reduzierten Edelstahlanteil, insbesondere in einem Gehäusebereich, aufweist, bei dem eine Funktionsintegration der Sensorfunktion direkt in das Rail ermöglicht ist und der als verschweißbares Einzelteil ausgeführt ist. Es ergeben sich insbesondere eine erhebliche Kostenreduzierung, eine erhebliche Montagezeitreduzierung, eine Variantenreduzierung und eine Funktionsintegration.In summary and in other words, the invention thus results in a plastic-encapsulated pressure sensor as a welded component, which is no longer made of stainless steel or at least has a reduced proportion of stainless steel, in particular in a housing region, in which functional integration of the sensor function directly into the rail is possible is and is designed as a weldable item. In particular, this results in a considerable cost reduction, a considerable reduction in assembly time, a reduction in variants and a functional integration.
