In order to make available a wheel-drive unit which saves space and can be easily assembled, it is proposed to design the gear mechanism as a planetary gear and to arrange it between the wheel-hub housing (2) and the axle housing (1), connected releasably thereto, in a manner such that it is coaxial with respect to the axis of rotation of the output shaft (17). The ring gear of the planetary gear is formed by an annular element (13), arranged between the axle housing (1) and the wheel-hub housing (2), whereas the sun gear is integrally formed in one piece on one end of a shaft (4), which is mounted in the axle housing (1), is connected to the hydrostatic motor (3) and is arranged coaxially with respect to the axis of rotation thereof. The planet gears (14) are mounted on a web (16) which is part of the output shaft (17). The wheel rim (21) is mounted on an axle flange (18) which is bolted to the output shaft (17). <IMAGE>

Description

Die Erfindung betrifft eine Radantriebseinheit mit einem hydrostatischen Motor, der unter Zwischenschaltung einer Lamellenbremse und eines Zahnradgetriebes an eine in einem Radnabengehäuse gelagerte Abtriebswelle angeschlossen ist.The invention relates to a wheel drive unit with a hydrostatic motor, with the interposition of a Multi-disc brake and a gear transmission to one in one Wheel hub housing mounted output shaft is connected.

Aus der DE-OS 34 06 783 ist eine Radantriebseinheit bekannt, bei der ein zweistufiges Stirnradgetriebe zwischen dem hydrostatischen Motor und der Abtriebswelle vorgesehen ist. Der Motor und die Abtriebswelle sind in verschiedenen Ebenen angeordnet, so daß die beschriebene Radantriebs­ einheit aufwendig aufgebaut ist und einen erheblichen Platz­ bedarf hat.A wheel drive unit is known from DE-OS 34 06 783, where a two-stage spur gear between the hydrostatic motor and the output shaft provided is. The motor and the output shaft are in different Levels arranged so that the wheel drive described unit is complex and takes up a significant amount of space needs.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine wirtschaftlich herstellbare Radantriebseinheit zur Verfügung zu stellen, die eine platzsparende Bauweise auf­ weist und leicht montierbar ist und deren Elemente zu Wartungszwecken gut zugänglich sind. The present invention is based on the object an economically producible wheel drive unit for To provide a space-saving design points and is easy to assemble and their elements Are easily accessible for maintenance purposes.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Zahnradgetriebe als mindestens einstufiges Planeten­ getriebe ausgebildet und koaxial zur Drehachse der Ab­ triebswelle zwischen dem Radnabengehäuse und einem damit lösbar verbundenen Achsgehäuse angeordnet ist, in dem koaxial zur gemeinsamen Drehachse von Abtriebswelle und Planetengetriebe die Lamellenbremse und der hydrostatische Motor angeordnet sind und das zur Befestigung an einem Fahrzeugrahmen ausgebildet ist. Die Verwendung eines Planetengetriebes anstelle eines zweistufigen Stirnrad­ getriebes ermöglicht eine platzsparende Bauweise, wobei die einzelnen Elemente im Gegensatz zum beschriebenen Stand der Technik nunmehr koaxial zueinander das heißt in der gleichen Ebene, angeordnet sind, was ebenfalls eine kom­ paktere Bauweise ermöglicht. Es kann ein einstufiges oder ein mehrstufiges Planetengetriebe vorgesehen sein. In jedem Fall wird auch eine Geräuschreduzierung erreicht, weil die von einem Planetengetriebe zu übertragende Last auf mehrere Zahneingriffstellen aufgeteilt wird. Vorzugsweise ist ein einstufiges Planetengetriebe vorgesehen, bei dem die Last auf mindestens zwei Planetenräder aufgeteilt wird.This object is achieved in that the gear transmission as at least one-stage planet gear designed and coaxial to the axis of rotation of the Ab drive shaft between the wheel hub housing and one with it releasably connected axle housing is arranged in the coaxial to the common axis of rotation of the output shaft and Planetary gear the multi-disc brake and the hydrostatic Motor are arranged and that for attachment to a Vehicle frame is formed. The use of a Planetary gear instead of a two-stage spur gear gear enables a space-saving design, whereby the individual elements in contrast to the state described the technology now coaxial with each other, that is in the same level, are arranged, which is also a com more compact design enables. It can be a single stage or a multi-stage planetary gear can be provided. In each Case, noise reduction is also achieved because the load to be transmitted by a planetary gear several tooth engagement points is divided. Preferably a single-stage planetary gear is provided, in which the load is divided between at least two planet gears.

Die Radantriebseinheit besteht im wesentlichen aus zwei die weiteren Bauelemente aufnehmenden Teilen, nämlich dem Achsgehäuse und dem Radnabengehäuse. Das Planetengetriebe ist an der Trennstelle, das heißt zwischen dem Radnaben­ gehäuse und dem Achsgehäuse angeordnet. Um zu Wartungs­ zwecken an die Lamellenbremse oder an das Planetengetriebe heran zu kommen, wird das Radnabengehäuse zusammen mit dem Planetengetriebe von dem Achsgehäuse getrennt. Es ist dabei wesentlich, daß das Achsgehäuse nicht vom Fahrzeug­ rahmen gelöst werden muß. The wheel drive unit essentially consists of two the other components receiving parts, namely the Axle housing and the wheel hub housing. The planetary gear is at the separation point, i.e. between the wheel hubs housing and the axle housing arranged. To maintenance for the multi-disc brake or the planetary gear to get close, the wheel hub housing is together with the planetary gear from the axle housing. It is essential that the axle housing is not from the vehicle frame must be solved.  

Das Radnabengehäuse baut zusammen mit dem Planetengetriebe sehr kurz. Das von der Radlast auf das Achsgehäuse ausge­ übte Biegemoment ist daher gering, wenn die Befestigungs­ stelle des Achsgehäuses am Fahrzeugrahmen zweckmäßigerweise unmittelbar der Trennstelle zum Radnabengehäuse benachbart liegt.The wheel hub housing builds together with the planetary gear very short. That from the wheel load on the axle housing Practiced bending moment is therefore low when fastening place the axle housing on the vehicle frame expediently immediately adjacent to the separation point to the wheel hub housing lies.

Das Hohlrad des Planetengetriebes kann sowohl in das Achs­ gehäuse als auch in das Radnabengehäuse eingearbeitet sein. Es ist jedoch gemäß einer Weiterbildung des Erfindungsgegen­ standes weitaus vorteilhafter, wenn das Hohlrad des Planeten­ getriebes von einem zwischen dem Radnabengehäuse und dem Achsgehäuse angeordneten Ringelement gebildet ist. Dieses kann dann sehr einfach hergestellt werden, während eine Einarbeitung des Verzahnungsprofils des Hohlrads in das Radnabengehäuse oder das Achsgehäuse sehr viel aufwendiger ist.The ring gear of the planetary gear can both in the axis Housing as well as be incorporated into the wheel hub housing. However, according to a further development of the invention was far more advantageous if the ring gear of the planet transmission of one between the wheel hub housing and the Axle housing arranged ring element is formed. This can then be made very easily while a Incorporation of the tooth profile of the ring gear in the Wheel hub housing or the axle housing is much more complex is.

Die beschriebene Radantriebseinheit ist mit besonderem Vorteil so ausgestaltet, daß die Abtriebswelle mit ihrem dem Achsgehäuse zugewandten Ende den Steg des Planeten­ getriebes bildet und mit dem entgegengesetzten Ende lösbar mit einem die Radfelge aufnehmenden Achsflansch verbunden ist. Es ist dadurch möglich, die Dichtvorrichtung zwischen dem rotierenden Achsflansch und dem feststehenden Radnaben­ gehäuse auszutauschen, ohne das Radnabengehäuse demontieren zu müssen. Die lösbare Verbindung zwischen Abtriebswelle und Achsflansch kann als Mitnahmeverzahnung, zum Beispiel Keilverzahnung, ausgeführt sein. The wheel drive unit described is special Advantage designed so that the output shaft with your the end of the planet facing the axle housing forms transmission and releasable with the opposite end connected to an axle flange receiving the wheel rim is. This makes it possible to place the sealing device between the rotating axle flange and the fixed wheel hubs replace housing without dismantling the wheel hub housing to have to. The detachable connection between the output shaft and axle flange can be used as driving teeth, for example Spline, be executed.  

Der Ein- und Ausbau des Planetengetriebes kann vereinfacht werden, wenn gemäß einer weiteren Ausgestaltung der Erfindung das Sonnenrad des Planetengetriebes einstückig an einem Ende einer in dem Achsgehäuse gelagerten Welle angeformt ist, die mit dem hydrostatischen Motor in Verbindung steht und koaxial zu dessen Drehachse angeordnet ist und von der Lamellenbremse koaxial umgeben ist. Diese Welle kann auch Teil des hydrostatischen Motors sein.The installation and removal of the planetary gear can be simplified if, according to a further embodiment of the invention the sun gear of the planetary gear unit in one piece Shaped end of a shaft mounted in the axle housing which is connected to the hydrostatic motor and is arranged coaxially to its axis of rotation and from the multi-disc brake is coaxially surrounded. This wave can also be part of the hydrostatic motor.

Die erfindungsgemäße Radantriebseinheit kann sowohl alleine als auch in Verbindung mit einer zweiten Einheit zum Einsatz kommen, so daß eine komplette Antriebsachse gebildet wird.The wheel drive unit according to the invention can be used alone as well as in connection with a second unit come so that a complete drive axle is formed.

Besonders vorteilhaft ist dann die Anwendung der erfindungs­ gemäßen Radantriebseinheit auf die Antriebsachse eines Gabelstaplers, wobei die Antriebsachse zusammen mit einem Hubgerüst am Fahrzeugrahmen befestigt ist. In diesem Fall ist es möglich, die Lamellenbremse oder das Planetengetriebe zu demontieren ohne die Antriebsachse auszubauen, was sonst auch einen Ausbau des Hubgerüstes erforderlich machen würde.The application of the invention is then particularly advantageous appropriate wheel drive unit on the drive axle of a Forklift truck, the drive axle together with a Mast is attached to the vehicle frame. In this case it is possible to use the multi-disc brake or the planetary gear disassemble without removing the drive axle, what else would also require an extension of the mast.

Die Erfindung soll anhand der nachfolgenden beschriebenen Figur in einem Ausführungsbeispiel näher erläutert werden. Hierbei zeigt die Figur einen Schnitt durch eine Antriebs­ halbachse, wobei die gesamte Antriebsachse aus zwei mit­ einander verschraubten Halbachsen besteht.The invention will be described with reference to the following Figure are explained in more detail in an embodiment. The figure shows a section through a drive semi-axis, the entire drive axle consisting of two with semi-axles screwed together.

Die erfindungsgemäße Radantriebseinheit besteht im wesent­ lichen aus zwei Baukörpern, nämlich einem Achsgehäuse 1 und einem Radnabengehäuse 2. In dem Achsgehäuse 1 ist ein hydrostatischer Motor 3 angeordnet, dessen Welle 4 außer­ halb des Motors stark verlängert und an ihrem Ende durch eine Verzahnung als Sonnenrad 5 eines Planetengetriebes ausgebildet ist. Die Welle 4 ist koaxial von einer Lamellen­ bremse 6 umgeben, deren Lamellen 7 wechselseitig mit dem Achsgehäuse 1 und einer mit der Welle 4 fest verbundenen Buchse 8 in Eingriff stehen. Die Lamellenbremse 6 ist über Federn 9 gespannt, sofern sie nicht durch unter Druck stehendes Öl, das in der Anschlußöffnung 10 ansteht, gelüftet ist.The wheel drive unit according to the invention consists in wesent union of two structures, namely an axle housing 1 and a wheel hub housing 2 . A hydrostatic motor 3 is arranged in the axle housing 1 , the shaft 4 of which is greatly extended outside the half of the motor and is formed at its end by teeth as a sun gear 5 of a planetary gear. The shaft 4 is coaxially surrounded by a disk brake 6 , the disks 7 are mutually engaged with the axle housing 1 and a fixed to the shaft 4 socket 8 . The multi-disc brake 6 is tensioned over springs 9 , provided that it is not released by oil under pressure which is present in the connection opening 10 .

Das feststehende Achsgehäuse 1 ist an seinem in der Figur linken Ende gegenüber der rotierenden Welle 4 durch eine Dichtvorrichtung 11 abgedichtet und mit dem Radnaben­ gehäuse 2 über Schrauben 12 verbunden. Zwischen dem Achs­ gehäuse 1 und dem Radnabengehäuse 2 ist ein Ringelement 13 angeordnet, das eine Innenverzahnung aufweist und als Hohlrad des Planetengetriebes vorgesehen ist. Das Planeten­ getriebe hat mindestens zwei Planetenräder 14, vorzugsweise aber drei Planetenräder 14, die über Wälzlager 15 auf einem Steg 16 gelagert sind, der Teil einer Abtriebswelle 17 ist. Die Abtriebswelle 17 ist über eine Keilverzahnung mit einem Achsflansch 18 lösbar verbunden und zusammen mit diesem im Radnabengehäuse 2 gelagert, wobei zwischen dieser aus Achsflansch 18 und Abtriebswelle 17 bestehenden rotierenden Einheit und dem Radnabengehäuse 2 eine Dicht­ vorrichtung 20 vorgesehen ist.The fixed axle housing 1 is sealed at its left end in the figure against the rotating shaft 4 by a sealing device 11 and connected to the wheel hub housing 2 via screws 12 . Between the axle housing 1 and the wheel hub housing 2 , a ring element 13 is arranged, which has an internal toothing and is provided as a ring gear of the planetary gear. The planetary gear has at least two planet gears 14 , but preferably three planet gears 14 , which are mounted on roller bearings 15 on a web 16 , which is part of an output shaft 17 . The output shaft 17 is releasably connected by splines with a shaft flange 18 and stored together therewith in the wheel hub housing 2, wherein between this from the axle flange 18 and output shaft 17 existing rotating unit and the wheel hub housing 2 device, a sealing is provided 20th

Am Achsflansch 2 ist mittels Schrauben 19 eine Radfelge 21 angebracht. Das Achsgehäuse 1 ist durch eine elastische Aufhängevorrichtung 22 mit einem in der Figur nicht dar­ gestellten Fahrzeugrahmen verbunden. In einer bevorzugten Ausführungsform handelt es sich bei dem Fahrzeug um einen Gabelstapler wobei an der Aufhängevorrichtung 22 der Hubmast 23 befestigt ist, der jedoch in der Figur ebenfalls nicht mehr dargestellt ist. A wheel rim 21 is attached to the axle flange 2 by means of screws 19 . The axle housing 1 is connected by an elastic suspension device 22 to a vehicle frame not shown in the figure. In a preferred embodiment, the vehicle is a forklift truck, the lifting mast 23 being fastened to the suspension device 22 , but this is also no longer shown in the figure.

Um zu Wartungszwecken an die Lamellenbremse 6 heranzukommen, beispielsweise zum Austausch von O-Ringen, oder um die Dichtvorrichtung 11 auszutauschen, wird nach Lösen der Schrauben 19 die Radfelge 21 abgenommen und durch Lösen der Schrauben 12 das Radnabengehäuse 2 vom Achsgehäuse 1 getrennt. Dabei verbleibt das Sonnenrad 5 des Planeten­ getriebes am Achsgehäuse 1 bzw. der Welle 4, während die Planetenräder 14 über die Verbindung mit dem Steg 16 ent­ fernt werden. Das Ringelement 13 ist lose und kann ebenfalls entfernt werden. Es ist aber auch möglich, daß eine Fixierung des Ringelementes 13 am Achsgehäuse 1 erfolgt oder am Rad­ nabengehäuse 2.In order to reach for maintenance purposes to the disk brake 6, such as exchange for the exchange of O-rings, or the sealing device 11 is taken off the wheel rim 21 by loosening the screws 19 and the wheel hub housing 2 from the axle housing 1 is separated by loosening the screws 12th The sun gear 5 of the planetary gear remains on the axle housing 1 or the shaft 4 , while the planet gears 14 are removed via the connection with the web 16 ent. The ring element 13 is loose and can also be removed. But it is also possible that the ring element 13 is fixed to the axle housing 1 or to the wheel hub housing 2 .

Um bei an das Achsgehäuse 1 angeschraubtem Radnabengehäuse 2 die Dichtvorrichtung 20 auszutauschen, wird nach Lösen einer Schraube 24, die über eine Buchse 25 den Achsflansch 18 mit der Abtriebswelle 17 verbindet, der Achsflansch 18 abgezogen. Es ist also nicht nötig, die Abtriebswelle 17 als solche auszubauen. Infolge der Verwendung eines Planeten­ getriebes und dessen Anordnung ist die Distanz zwischen der Aufhängevorrichtung 22 und der Wirklinie der aus der Radlast resultierenden Kraft gering, so daß nur ein geringes Biegemoment das Achsgehäuse belastet.In order to replace at bolted to the axle housing 1 wheel hub housing 2, the sealing device 20, a screw 24, which connects via a bushing 25 to the axle flange 18 to the output shaft 17, the shaft flange 18 is removed after loosening. It is therefore not necessary to remove the output shaft 17 as such. Due to the use of a planetary gear and its arrangement, the distance between the suspension device 22 and the line of action of the force resulting from the wheel load is small, so that only a small bending moment loads the axle housing.
