Description
Die Erfindung betrifft einen hydrostatischer Nabenantrieb mit integrierter Axialkolbenmaschine in Schrägscheibenbauweise, insbesondere einen Radnabenantrieb, mit einem feststehenden, als Maschinengehäuse der Axialkolbenmaschine ausgebildeten Nabenträger, einer darin drehbar gelagerten, von einer Maschinenwelle gebildeten Nabe und einer als Wellenlagerung ausgebildeten Nabenlagerung.The The invention relates to a hydrostatic hub drive with integrated Axial piston machine in swash plate design, in particular a wheel hub drive, with a fixed, as machine housing the axial piston machine formed hub carrier, a rotatably mounted therein, hub formed by a machine shaft and a shaft bearing trained hub bearing.
Ein
derartiger Nabenantrieb ist aus der
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde einen hydrostatischen Nabenantrieb der eingangs genannten Art zur Verfügung zu stellen, dessen Herstellungs- und Montageaufwand verringert ist.Of the The present invention is based on the object of a hydrostatic Hub drive of the type mentioned above to provide whose manufacturing and assembly costs is reduced.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Axialkolbenmaschine als Einzeltriebwerk ausgebildet ist und einen einzelnen Zylinderblock auf der durch eine Austrittsöffnung aus dem Maschinengehäuse herausgeführten Maschinenwelle aufweist, wobei eine Schrägscheibe in einem der Austrittsöffnung nahen Bereich und eine Steuerbodenaufnahme in einem der Austrittsöffnung fernen Bereich angeordnet ist. Der erfindungsgemäße Nabenantrieb weist somit nur wenige leicht herstell- und montierbare Einzelteile auf.These Task is inventively characterized solved, that the axial piston machine is designed as a single engine and a single cylinder block on the through an outlet opening of the machine housing led out Machine shaft, with a swash plate close in one of the outlet opening Remove the area and a control floor receptacle in one of the outlet openings Area is arranged. The hub drive according to the invention thus has only a few easily manufacturable and mountable items.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist der Axialkolbenmotor als Konstantmotor ausgeführt und die Schrägscheibe im Maschinengehäuse angeformt. Dabei wird der Herstellungsaufwand für die genannten Teile dadurch minimiert, daß sie einstückig miteinander ausgebildet sind.According to one advantageous embodiment of the invention is the axial piston motor designed as a constant motor and the swash plate in the machine housing formed. In this case, the manufacturing cost of the said parts is characterized minimizes that one piece are formed with each other.
Eine zweckmäßige Weiterbildung der Erfindung sieht vor, dass die Schrägscheibe derart angeordnet ist, daß die Radialkomponenten der Triebwerkskräfte im Betriebszustand den von außen auf die Nabenlagerung einwirkenden Kräften entgegengerichtet wirksam sind. Die Nabenlagerung wird daher entlastet, was zu einer erhöhten Lebensdauer beiträgt.A appropriate training The invention provides that the swash plate arranged in such a way is that the Radial components of the engine forces in the operating state the from the outside counteracting forces acting on the hub bearing effectively are. The hub bearing is therefore relieved, which contributes to an increased life.
Montagetechnisch günstig ist es, wenn an dem Maschinengehäuse ein als Steuerbodenaufnahme ausgebildeter Abschlussdeckel lösbar befestigt ist.Technically assembly Cheap is it when on the machine housing a trained as a control ground absorption end cover is releasably secured.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Nabenantriebs ist radial zwischen dem Zylinderblock und dem Maschinengehäuse eine Bremse angeordnet.According to one advantageous embodiment of the hub drive according to the invention is radially between arranged a brake on the cylinder block and the machine housing.
Gemäß einer günstigen Variante hierzu ist es auch möglich, in einer Ausnehmung des Abschlussdeckels eine in Wirkverbindung mit der Maschinenwelle stehende Bremse anzuordnen. Dabei ist die Bremse leichter zugänglich (beispielsweise zu Wartungszwecken). Im eingebauten Zustand des Nabenantriebs kann durch bloße Entfernung des Abschlussdeckels die Bremse demontiert werden.According to one Great Variant, it is also possible in a recess of the end cover one in operative connection To arrange with the machine shaft standing brake. Here is the brake more accessible (for maintenance purposes, for example). In the installed state of the Hub drive can by mere Removing the end cover the brake can be dismantled.
In diesem Zusammenhang ist es zweckmäßig, wenn die Bremse einen federkraftbeaufschlagten Bremskolben aufweist, der entgegen der Wirkung der Federkraft an einem Federwiderlager mechanisch festlegbar ist. Eine solche Federspeicherbremse kann bei arretiertem Bremskolben auf einfache Weise und ohne Unfallgefahren demontiert werden. Darüber hinaus bietet diese Ausgestaltung die Möglichkeit, ein mit den erfindungsgemäßen Nabenantrieben ausgestattetes Fahrzeug, dessen Bremsen geschlossen sind und nicht mit Hilfe von Betriebsdruck geöffnet werden können, abzuschleppen, indem die Bremsen mechanisch geöffnet werden.In In this context, it is useful if the brake a Has spring-loaded brake piston, which counter to Effect of the spring force on a spring abutment mechanically fixable is. Such a spring brake can with locked brake piston be dismantled in a simple manner and without risk of accidents. Furthermore this embodiment offers the possibility a with the hub drives according to the invention equipped vehicle whose brakes are closed and not opened with the help of operating pressure can be to tow by mechanically opening the brakes.
Sofern die Bremse als nasslaufende Federspeicher-Lamellenbremse ausgebildet ist, werden Vorteile im Hinblick auf eine gute Raumausnutzung und eine hohe Leistungsfähigkeit erzielt.Provided the brake is designed as a wet-running spring-loaded multi-disc brake is to be advantages in terms of good space utilization and a high performance achieved.
Es erweist sich als vorteilhaft, wenn das Maschinengehäuse einen Befestigungsflansch des Nabenantriebs aufweist, wobei der Abschlussdeckel im befestigten Zustand des Nabenantriebs lösbar ist. Dadurch ist es z. B. möglich, Wartungsarbeiten an der Bremse auszuführen, ohne den Nabenträger zu lösen.It proves to be advantageous if the machine housing a Attachment flange of the hub drive, wherein the end cover in the attached state of the hub drive is solvable. This is z. Possible, Perform maintenance on the brake without loosening the hub carrier.
Zur Verringerung der Anzahl der Bauteile ist es günstig, wenn ein zur Aufnahme mindestens einer Radfelge ausgebildeter Radflansch an der Maschinenwelle angeformt ist. Dies senkt den Montageaufwand. In diesem Zusammenhang sind Ausgestaltungen zweckmäßig, bei der der Radflansch eine Felgenzentrierung und konzentrische Gewindebohrungen aufweist.to Reducing the number of components is beneficial if one is to take up at least one wheel rim trained wheel flange on the machine shaft is formed. This reduces the assembly effort. In this context Embodiments are expedient, at the wheel flange has a rim centering and concentric tapped holes having.
