Abstract
Description
Die Erfindung betrifft einen elektrisch angetriebenen Taumelscheibenkompressor, insbesondere für eine mit CO2-Kältemittel betriebene Fahrzeug-Klimaanlage.The invention relates to an electrically driven swash plate compressor, in particular for a powered with CO 2 refrigerant vehicle air conditioning.
Elektrisch angetriebene Taumelscheibenkompressoren können vorteilhaft in Kraftfahrzeug-Klimaanlagen anstelle von mit dem Verbrennungsmotor des Kraftfahrzeugs gekoppelten, also mechanisch angetriebenen Taumelscheibenkompressoren (Kompressoren), eingesetzt werden, da diese auf einfache Weise über die Ansteuerfrequenz des jeweiligen (Antriebs-) Elektromotors drehzahlregelbar sind. Ein solcher Kompressor weist ein Gehäuse auf, in dem in einem Antriebsraum der Elektromotor und in einer Kurbelkammer eine auf einer Antriebswelle drehfest angeordnete Taumelscheibe untergebracht sind, wobei der Rotor des Elektromotors drehfest mit der Antriebswelle verbunden ist. Der Stator des Elektromotors ist mit dem Kompressorgehäuse in axialer Richtung fest verschraubt, wozu dieses entsprechend gestaltet ist. In der Regel besteht das Kompressorgehäuse aus Aluminium-Druckguss.electrical powered swash plate type compressors can be beneficial in automotive air conditioning systems instead of coupled to the internal combustion engine of the motor vehicle, ie mechanically driven swash plate compressors, be used because these in a simple way on the drive frequency of the respective (drive) electric motor speed controlled. One such compressor has a housing on, in which in a drive space the electric motor and in a Crank a rotatably mounted on a drive shaft swash plate are accommodated, wherein the rotor of the electric motor rotatably with the drive shaft is connected. The stator of the electric motor is with the compressor housing firmly screwed in the axial direction, what this designed accordingly is. As a rule, the compressor housing is made of die-cast aluminum.

Es ist Aufgabe der Erfindung, einen elektrisch angetriebenen Taumelscheibenkompressor nach dem Oberbegriff des Anspruchs 1 vereinfacht zu gestalten, so dass dessen Montage erleichtert ist.It Object of the invention, an electrically driven swash plate compressor after simplified to make the preamble of claim 1, so that its assembly is facilitated.
Diese Aufgabe wird bei einem Taumelscheibenkompressor nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnenden Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den nachfolgenden Unteransprüchen aufgeführt.These Task is in a swash plate compressor according to the preamble of claim 1 solved by its characterizing features. advantageous Embodiments are listed in the following subclaims.
Die Erfindung besteht danach darin, dass das Gehäuse eines elektrisch angetriebenen Taumelscheibenkompressors, in dem in bekannter Weise in einer Kurbelkammer eine mit wenigstens einem Hubkolben zum Ansaugen und Verdichten von Kältemittel gekoppelte Taumelscheibe auf einer Antriebswelle untergebracht ist, und in dem in einem Antriebsraum ein Elektromotor angeordnet ist, dessen Rotor mit der Antriebswelle drehfest verbunden ist und dessen Stator am Gehäuse befestigt ist, das Gehäuse aus Stahl besteht und tiefgezogen ist, und dass dieses mit dem Stator schrumpfverbunden ist. Der Vorteil liegt in einer einfacheren und somit kostengünstigeren Gestaltung des Kompressorgehäuses, da unterschiedliche Wanddicken zur Ausbildung einer Anlageschulter für den Stator im Innern des Gehäuses bzw. von Befestigungsansätzen für Schraubverbindungen in axialer Richtung zur Befestigung des Stators nicht benötigt werden, und in einer vereinfachten und kostengünstigeren Montage des Kompressors. Dabei ist es von besonderem Vorteil, dass sich der Stator beim Schrumpfverbindungsvorgang im Gehäuse selbst zentriert. Das Aufschrumpfen des Gehäuses auf den Stator kann vorteilhaft induktiv in einer rohrförmigen Einrichtung erfolgen.The Invention is then that the housing of an electrically driven Swash plate compressor, in which in a known manner in a crank chamber one with at least one reciprocating piston for suction and compression of refrigerant coupled swash plate is housed on a drive shaft, and in which an electric motor is arranged in a drive space, whose rotor is rotatably connected to the drive shaft and whose Stator on the housing is attached, the housing Made of steel and deep-drawn, and that this with the stator is shrink-connected. The advantage lies in a simpler and thus cheaper Design of the compressor housing, because different wall thicknesses to form a contact shoulder for the Stator inside the case or from fastening lugs for screw connections not needed in the axial direction for attachment of the stator, and in a simplified and less expensive installation of the compressor. It is of particular advantage that the stator during the shrink connection process in the case self centered. The shrinking of the housing on the stator can be advantageous inductively in a tubular Establishment done.
Ein weiterer Vorteil liegt in der relativ geringen Wanddicke des Gehäuses durch den Einsatz von Stahl. Wegen dessen höherer und auch bleibender Festigkeit beim Betreiben des Kompressors, insbesondere mit CO2-Kältemittel bei sehr hohen Drücken bis zu ca. 180 bar und Temperaturen von über 100°C, kann die Wanddicke reduziert werden. Es hat sich gezeigt, dass eine Wanddicke im Bereich zwischen 2,5 mm und 4 mm völlig ausreicht. Dadurch, dass der Kompressor als einheitliche Komponente ein Verschleißteil darstellt, ist es durch die Verwendung von Stahl auch möglich, den elektromotorseitigen Abschlussdeckel und den Ventildeckel mit dem Gehäuse zu verschweißen. Bei einem verschweißten Gehäuse sind die Leckverluste gegenüber einem verschraubten geringer.Another advantage is the relatively small wall thickness of the housing through the use of steel. Because of its higher and permanent strength when operating the compressor, especially with CO 2 refrigerant at very high pressures up to about 180 bar and temperatures above 100 ° C, the wall thickness can be reduced. It has been found that a wall thickness in the range between 2.5 mm and 4 mm is completely sufficient. The fact that the compressor is a wear part as a uniform component, it is also possible by the use of steel, the electric motor-side end cover and the valve cover to weld to the housing. In a welded housing, the leakage losses are lower compared to a bolted.
Zur Befestigung des Kompressors dient eine Befestigungsring, der umfangsseitig am Gehäuse lösbar angeordnet ist und der mehrere Befestigungselemente, insbesondere mit jeweils einem Befestigungsloch versehene und in tangentialer Richtung angeformte Befestigungslaschen, aufweist. Dabei ist der Befestigungsring zwischen zwei einander zugeordneten Befestigungselementen unterbrochen und am Kompressorgehäuse klemmfixierbar. Somit ist der Befestigungsring zugleich als Bandschelle zur Stützung des Gehäuses gegenüber den in diesem herrschenden hohen Drücken einsetzbar. Er ist in axialer Kompressorrichtung in variabler Lage anordbar und gegenüber dem Gehäuse an keine Winkelstellung gebunden. Durch diesen Befestigungsring ist eine Montage des Kompressors in beengten Bauräumen erheblich erleichtert, die eine bestimmte Kompressorstellung für den Anschluss an die Druckleitungen der Klimaanlage erfordert. Der zu montierende Kompressor kann über den Befestigungsring vormontiert, anschließend erleichtert ausgerichtet und endmontiert werden. Überdies kann der Kompressor an eine Vielzahl fahrzeugtypspezifischer Befestigungseinrichtungen montiert werden, was wiederum zu einer Reduzierung der Gehäusevielfalt führen kann.to Attaching the compressor is a fixing ring, the circumference detachably arranged on the housing is and the plurality of fasteners, in particular with each a fastening hole provided and integrally formed in the tangential direction Fastening straps, having. Here is the mounting ring between interrupted two associated fasteners and on Compressor housing can be clamped. Thus, the mounting ring at the same time as a band clamp to support the housing across from can be used in this prevailing high pressures. He is in axial Compressor device in variable position can be arranged and opposite the casing bound to no angular position. Through this fastening ring is considerably simplifies installation of the compressor in confined spaces, the one particular compressor position for connection to the pressure lines the air conditioning requires. The compressor to be mounted can via the Pre-assembled mounting ring, then aligned aligned and easier be assembled. moreover For example, the compressor may be attached to a variety of vehicle type-specific fasteners be mounted, which in turn leads to a reduction in housing diversity to lead can.
