Abstract
Description
Die Erfindung betrifft eine Antriebseinrichtung für Kraftfahrzeuge gemäß der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The The invention relates to a drive device for motor vehicles according to the Generic term of claim 1 specified.
Eine
solche Antriebseinrichtung ist aus der
Eine
der vorgenannten ähnliche

Der vorliegenden Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Antriebseinrichtung der eingangs erwähnten Art dahingehend zu ändern, dass die Kupplung zwischen Hydropumpe und Antriebseinrichtung und auch der Rest der Antriebseinrichtung auf einfachere und kostengünstigere Weise realisierbar ist.Of the The present invention is based on the object, a Drive device of the type mentioned above to change that the coupling between hydraulic pump and drive device and also the rest of the drive device to simpler and cheaper Way is feasible.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale von Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.According to the invention this Problem solved by the features of claim 1. Advantageous embodiments The invention are characterized in the subclaims.
Dadurch, dass die Hydropumpe erfindungsgemäß koaxial auf der Ausgangswelle des Gangswechselgetriebes angeordnet und über diese permanent antreibbar ist, ergibt sich eine sehr kompakte Anordnung. Es wird keine eigenständige Kupplung mehr benötigt, denn die Hydropumpe ist von einer Bauart, die intern eine entsprechende Kupplungsfunktion ermöglicht. Als Kupplungselemente dienen dabei die Kolben und die sinusförmig gewellte Laufbahn sowie die Federelemente, welche Kolben abhängig vom Speisedruck der Speisepumpe in und außer Wirkposition bringbar sind.Thereby, that the hydraulic pump according to the invention coaxially on the output shaft arranged the gear change transmission and permanently driven over this is, results in a very compact arrangement. There will be no independent clutch more needed because the hydraulic pump is of a type that internally a corresponding Coupling function allows. As coupling elements serve the piston and the sinusoidal corrugated Track and the spring elements, which depends on the piston Supply pressure of the feed pump in and out of operative position can be brought.
Da keine zusätzliche Kupplung zur Herstellung der Antriebsverbindung zwischen Antriebseinrichtung und Hydropumpe mehr notwendig ist, wird das System schon aus diesem Grund billiger.There no additional Coupling for producing the drive connection between the drive device and hydraulic pump is more necessary, the system is already out of this Reason cheaper.
Eine weitere Kostenreduzierung lässt sich dadurch erzielen, dass erfindungsgemäß sowohl die Hydropumpe als auch die Hydromotoren durch bauartgleiche Hochmoment-Radialkolbenmaschinen realisiert sind. Dies hat außerdem den großen Vorteil, dass dann, wenn die Hydropumpe abgeschaltet ist, auch die Hydromotoren abgeschaltet sind, d. h., deren Kolben ebenfalls außer Eingriff mit der sinusförmig gewellten Laufbahn sind, und solchermaßen die Schleppverluste minimiert sind.A further cost reduction leaves be achieved in that according to the invention both the hydraulic pump as also implemented the hydraulic motors by identical construction high-torque radial piston machines are. This also has the big one Advantage that when the hydraulic pump is switched off, the Hydraulic motors are switched off, d. h., The piston also disengaged with the sinusoidal corrugated career, and thus minimizes drag losses are.
Die weiteren erfindungsgemäßen Merkmale betreffen jene Details der verwendeten Art von Hochmoment-Radialkolbenmaschinen, die die vorgenannten Funktionalitäten erfüllen.The relate to further features of the invention those details of the type of high-momentum radial piston engines used, which fulfill the aforementioned functionalities.
Auf diese Weise ist es problemlos möglich, den Förderstrom der die Hydropumpe bildenden Hochmoment-Radialkolbenmaschine, ohne dass es der Zwischenschaltung eines Hydrogetriebes bedürfte, an das Schluckvolumen der den Fahrzeugrädern zugeordneten, die Hydromotoren bildenden Hochmoment-Radialkolbenmaschinen anzupassen.On this way it is easily possible, the flow the hydropump forming high-torque radial piston machine, without that it would require the interposition of a hydraulic transmission to the displacement of the vehicle wheels associated with the hydraulic motors adapting high-torque radial piston machines.
