Description
Die vorliegende Erfindung betrifft einen Kettentrieb für eine Getriebepumpe eines Automatgetriebes für ein Kraftfahrzeug, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a chain drive for a gear pump an automatic transmission for a motor vehicle, according to the preamble of Patent claim 1.
Der Gegenstand der vorliegenden Erfindung soll auch für die Getriebepumpe eines stufenlosen Umschlingungsgetriebes geeignet sein, welche u.a. die Druckölversorgung zur Variatorverstellung übernimmt.Of the The subject of the present invention is also intended for the gear pump a continuously variable transmission, which u.a. the Oil supply to variator adjustment takes over.
Aus dem Stand der Technik ist bekannt, dass derartige Getriebepumpen mittels eines Kettentriebs angetrieben werden, um auf diese Weise mit einer gegenüber dem Antriebsmotor veränderten Übersetzung betrieben zu werden. Üblicherweise wird der Kettentrieb von einem Drehmomentwandler oder alternativ von einer hydrodynamischen Kupplung angetrieben. Hierbei lässt der Kettentrieb nur einen sehr geringen Kettenschräglauf zu.Out the prior art is known that such gear pumps be driven by a chain drive to this way with one opposite the drive motor changed translation to be operated. Usually The chain drive is powered by a torque converter or alternatively driven by a hydrodynamic clutch. This leaves the Chain drive only a very small Kettenschräglauf to.
Aus
der
Bei den genannten Kettentrieb-Konstruktionen entsteht das Problem, dass aufgrund der axialen Verformung des Drehmomentwandlers bzw. der hydrodynamischen Kupplung unter Innendruck, diese Verformung auf den Kettentrieb übertragen werden kann, wodurch der Betrieb der Getriebepumpe beeinträchtigt wird, da lediglich ein geringer Kettenschräglauf zulässig ist.at The aforementioned chain drive constructions creates the problem that due to the axial deformation of the torque converter or the hydrodynamic coupling under internal pressure, this deformation on transmit the chain drive which may affect the operation of the gear pump, because only a small chain skew is allowed.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Kettentrieb für eine Getriebepumpe eines Automatgetriebes für ein Kraftfahrzeug anzugeben, welcher den genannten Nachteil des Standes der Technik vermeidet. Insbesondere soll der Kettentrieb derart ausgebildet sein, dass eine axiale Verformung des Drehmomentwandlers bzw. der hydrodynamischen Kupplung nicht auf den Kettentrieb übertragen werden kann.Of the present invention is based on the object, a chain drive for one Specify gear pump of an automatic transmission for a motor vehicle, which avoids the mentioned disadvantage of the prior art. In particular, the chain drive should be designed such that an axial deformation of the torque converter or the hydrodynamic Coupling can not be transferred to the chain drive.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Vorteile und vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.These The object is achieved by the Characteristics of claim 1 solved. Further advantages and advantageous Embodiments will become apparent from the dependent claims.
Demnach wird ein Kettentrieb für eine Getriebepumpe eines Automatgetriebes vorgeschlagen, umfassend ein von einem Drehmomentwandler oder einer hydrodynamischen Kupplung über eine Welle angetriebenes Kettenrad, wobei das Kettenrad zur Übertragung der Drehbewegung und des Drehmomentes zumindest einen Mitnahmefinger aufweist, bei dem der Kontakt- bzw. Mitnahmebereich über den die Drehzahl und das Drehmoment vom Drehmomentwandler bzw. von der hydrodynamischen Kupplung auf das Kettenrad des Kettentriebs übertragen werden, sowohl bei dem antreibenden Teil als auch bei dem angetriebenen Kettenrad in Längsrichtung angeschrägt ausgebildet ist.Therefore becomes a chain drive for proposed a gear pump of an automatic transmission, comprising one of a torque converter or a hydrodynamic clutch via a Shaft driven sprocket, with the sprocket for transmission the rotational movement and the torque at least one driving finger has, in which the contact or entrainment area on the Speed and torque from the torque converter or from the hydrodynamic Coupling can be transferred to the sprocket of the chain drive, both at the driving part as well as the driven sprocket in Longitudinal tapered formed is.
Auf diese Weise entsteht eine Kraftkomponente in axialer Richtung, so dass das Kettenrad unter Nutzung des Prinzips der schiefen Ebene unabhängig von der Axialbewegung des Wandlers bzw. der Kupplung immer in eine bestimmte Richtung gedrückt wird.On This way, a force component in the axial direction, so that the sprocket taking advantage of the principle of the inclined plane independently from the axial movement of the converter or the clutch always in one pressed certain direction becomes.
Im Rahmen einer vorteilhaften Weiterbildung der Erfindung wird zudem vorgeschlagen, den axialen Weg des Kettenrades in Kraftrichtung über einen Anschlag zu begrenzen, so dass in vorteilhafter Weise nur Bauteiltoleranzen und nicht die Axialbewegung des Wandlers bzw. der hydrodynamischen Kupplung in den Kettenschräglauf eingehen.in the Within the scope of an advantageous embodiment of the invention is also proposed, the axial path of the sprocket in the direction of force via a stop limit, so that advantageously only component tolerances and not the axial movement of the transducer or the hydrodynamic coupling in the chain skew received.
Der Winkel der Schräge liegt vorzugsweise im Interwall 4,5°–8,5° und ist als Funktion des Reibwertes im Kontakt- bzw. Mitnahmebereich bestimmbar.Of the Angle of the slope is preferably in the interwall 4.5 ° -8.5 ° and is a function of the coefficient of friction determinable in the contact or driving range.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen:The The invention will be explained in more detail below by way of example with reference to the attached figures. Show it:
