Description

Hydraulischer Radialkolbenmotor Hydraulic radial piston motor
Die Erfindung bezieht sich auf einen hydraulischen Radialkolbenmotor nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a hydraulic radial piston motor according to the closer defined in the preamble of claim 1.
Hydraulische Radialkolbenmotore werden beispielsweise zum Antrieb eines Fahrmischergetriebes verwendet, wie in der DE 10 2004 057 849 A1 offenbart. Hierbei wird ein Gehäuseteil, in welchem ein hydraulischer Verteiler angeordnet ist, mit einem weiteren Gehäuseteil verschraubt, wobei zwischen dem Gehäuseteil und dem weiteren Gehäuseteil eine Kurvenscheibe angeordnet ist. Ein Rotationszylinder, welcher sich im Betriebszustand um eine Rotationsachse dreht, weist radial angeordnete Kolben auf, welche mit der Kurvenscheibe in Wirkverbindung sind, und stützt sich im Betriebszustand über ein Lager auf dem weiteren Gehäuseteil ab. Im Servicefall werden die Schrauben, mit welchen das Gehäuseteil und der Rotationszylinder mit dem weiteren Gehäuseteil verbunden sind, entfernt, und der hydraulische Radialkolbenmotor in Einzelteilen vom Fahrmischer abgebaut. Der Austausch des kompletten Aggregats ist nicht möglich, da durch die Entfernung der Schrauben der hydraulische Motor nicht mehr zusammengehalten wird.Hydraulic radial piston motors are used for example for driving a truck mixer transmission, as disclosed in DE 10 2004 057 849 A1. Here, a housing part, in which a hydraulic distributor is arranged, screwed to a further housing part, wherein between the housing part and the further housing part a cam is arranged. A rotary cylinder, which rotates in the operating state about an axis of rotation, has radially arranged pistons, which are in operative connection with the cam disk, and is supported in the operating state via a bearing on the further housing part. In case of service, the screws with which the housing part and the rotary cylinder are connected to the other housing part, removed, and dismantled the hydraulic radial piston motor in parts from the truck mixer. The replacement of the complete unit is not possible because the removal of the screws, the hydraulic motor is no longer held together.
Die FR 2 576 363 offenbart einen hydraulischen Radialkolbenmotor, bei welchem das Gehäuseteil der Rotationszylinder und das weitere Gehäuseteil als Baueinheit mit dem weiteren Getriebegehäuse über Schrauben verbunden werden. Diese Anordnung benötigt eine weitere Gehäusescheibe zwischen dem Getriebegehäuse und dem hydraulischen Motor, wodurch die axiale Baulänge erheblich vergrößert wird.FR 2 576 363 discloses a hydraulic radial piston motor in which the housing part of the rotary cylinder and the further housing part are connected as a unit with the other gear housing via screws. This arrangement requires a further housing plate between the gear housing and the hydraulic motor, whereby the axial length is considerably increased.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen hydraulischen Motor zu schaffen, welcher im Servicefall als Baueinheit austauschbar ist, ohne das sich die axiale Baulänge des hydraulischen Motors verlängert. Die Aufgabe wird mit einem, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden, gattungsgemäßen hydraulischen Radialkolbenmotor gelöst.The present invention has for its object to provide a hydraulic motor, which is interchangeable as a structural unit in the service case, without extending the axial length of the hydraulic motor. The object is achieved with a, including the characterizing features of the main claim having, generic hydraulic radial piston motor.
Der hydraulische Radialkolbenmotor weist ein Gehäuseteil auf, in welchem sich ein hydraulischer Verteiler befindet und welcher über Verbindungsmittel mit der Kurvenscheibe verbunden ist. Der Rotationszylinder weist radial angeordnete Kolben auf, welche mit der Kurvenscheibe in Verbindung stehen. Die Kurvenscheibe ist dreh- und ortsfest über Verbindungsmittel mit dem Gehäuseteil verbunden, wobei diese Verbindung auch im demontierten Zustand vorhanden ist. Im demontierten Zustand stützt sich der Rotationszylinder entlang seiner Rotationsachse entgegen der Richtung, in welcher er mit dem hydraulischen Verteiler in Verbindung steht, auf der Kurvenscheibe ab. Hierzu besteht die Möglichkeit, dass der Rotationszylinder auf der dem Verteiler zugewandten Seite einen Bund mit einem größeren Durchmesser aufweist als der Innendurchmesser der Kurvenscheibe, wodurch dieser Bund an der Kurvenscheibe zumindest teilweise zur Anlage bringbar ist.The hydraulic radial piston motor has a housing part, in which there is a hydraulic distributor and which is connected via connecting means with the cam disc. The rotary cylinder has radially arranged pistons which communicate with the cam. The cam is rotatably and fixedly connected via connecting means to the housing part, wherein this compound is also present in the disassembled state. In the disassembled state, the rotary cylinder is supported on the cam along its axis of rotation opposite to the direction in which it communicates with the hydraulic distributor. For this purpose, there is the possibility that the rotary cylinder on the side facing the distributor has a collar with a larger diameter than the inner diameter of the cam, whereby this collar on the cam is at least partially engageable.
In einer weiteren Ausgestaltungsform besteht die Möglichkeit, dass der Rotationszylinder auf der dem Ölverteiler zugewandten Seite eine Nut aufweist, in welche ein Ring einbringbar ist, welcher sich einerseits am Rotationszylinder und andererseits an der Kurvenscheibe abstützen kann. Der hydraulische Verteiler weist Federn auf, wodurch der hydraulische Verteiler gegen den Rotationszylinder gedrückt wird. Im Servicefall, wenn der hydraulische Radialkolbenmotor von dem weiteren Gehäuseteil getrennt ist, drücken die Federn den Verteiler gegen den Rotationszylinder und der Rotationszylinder stützt sich auf der Kurvenscheibe ab. Da die Kurvenscheibe mit dem Gehäuseteil verbunden ist, bleibt der hydraulische Radialkolbenmotor als Baueinheit zusammen.In a further embodiment, there is the possibility that the rotary cylinder on the oil distributor side facing a groove into which a ring can be introduced, which can be supported on the one hand on the rotary cylinder and on the other hand on the cam. The hydraulic distributor has springs, whereby the hydraulic distributor is pressed against the rotary cylinder. In case of service, when the hydraulic radial piston motor is separated from the other housing part, the springs press the distributor against the rotary cylinder and the rotary cylinder is supported on the cam. Since the cam is connected to the housing part, the hydraulic radial piston motor remains together as a structural unit.
In einer weiteren Ausgestaltungsform kann diese Baueinheit zusätzlich eine Antriebswelle aufweisen, auf welcher der Innenring eines Lagers angeord- net ist, wobei die Antriebswelle so ausgebildet ist, dass der Innenring des Lagers, zumindest in axialer Richtung, auf der Antriebswelle und die Antriebswelle ortsfest im hydraulischen Radialkolbenmotor gehalten sind. Hierfür kann die Antriebswelle eine Nut mit einem Sicherungsring aufweisen, welcher sich an der Fläche, an welcher der Verteiler am Rotationszylinder anliegt, abstützt, oder die Antriebswelle kann einen Bund aufweisen, welcher sich ebenso, wie der zuvor beschriebene Sicherungsring, an der Fläche des Rotationszylinders abstützt.In a further embodiment, this assembly may additionally have a drive shaft on which the inner ring of a bearing angeord- is net, wherein the drive shaft is formed so that the inner ring of the bearing, at least in the axial direction, on the drive shaft and the drive shaft are held stationary in the hydraulic radial piston motor. For this purpose, the drive shaft may have a groove with a locking ring, which is supported on the surface on which the distributor rests on the rotary cylinder, or the drive shaft may have a collar which, just like the locking ring described above, on the surface of the rotary cylinder supported.
In einer weiteren Ausgestaltungsform der Erfindung kann die Antriebswelle einen Stab, welcher das Gehäuseteil, in welchem der Verteiler angeordnet ist, durchdringt, aufweisen, wobei sich die Antriebswelle über den Stab, zumindest in axialer Richtung, an diesem Gehäuseteil abstützt. Der Stab kann einstückig mit der Antriebswelle ausgebildet sein, es besteht jedoch auch die Möglichkeit, den Stab als Schraube auszubilden, wobei die Schraube in die Antriebswelle eingeschraubt wird, um die Antriebswelle, den Innenring des Lagers und den Rotationszylinder in Richtung des Verteilers zu halten. Hierfür weist das Gehäuseteil, in welchem der Verteiler angeordnet ist oder ein mit diesem verbundenes Gehäuseteil, einen Durchbruch auf, durch welchen der Stab oder die Schraube das Gehäuseteil durchdringt, um mit der Antriebswelle verbunden zu sein. Der Stab oder die Schraube stützt sich über eine Erweiterung am Gehäuseteil ab. In einer Ausgestaltungsform kann im montierten Zustand des Radialkolbenmotors die Schraube entfernt werden.In a further embodiment of the invention, the drive shaft, a rod, which penetrates the housing part, in which the distributor is arranged, penetrate, wherein the drive shaft via the rod, at least in the axial direction, is supported on this housing part. The rod may be integrally formed with the drive shaft, but it is also possible to form the rod as a screw, wherein the screw is screwed into the drive shaft to hold the drive shaft, the inner ring of the bearing and the rotary cylinder in the direction of the distributor. For this purpose, the housing part in which the distributor is arranged or a housing part connected to this, an opening, through which the rod or the screw penetrates the housing part to be connected to the drive shaft. The rod or screw is supported by an extension on the housing part. In one embodiment, the screw can be removed in the assembled state of the radial piston motor.
Somit ist es möglich, den Radialkolbenmotor im Servicefall vom weiteren Gehäuseteil zu trennen, ohne dass der Radialkolbenmotor in seine Einzelteile zerfällt.Thus, it is possible to separate the radial piston motor in case of service from the other housing part, without the radial piston engine disintegrates into its individual parts.

Figure 2 shows a detail of this radial piston motor, wherein the rotary cylinder is supported on the cam. 3 shows a radial piston motor with a drive shaft, which is held by a screw, and FIG. 4 shows a radial piston motor with a drive shaft, which is held by a rod.
Fig. 1 :Fig. 1:
Ein hydraulischer Radialkolbenmotor 1 weist eine Kurvenscheibe 2 auf, welche über Rollen 3 und Kolben 4 mit einem Rotationszylinder 5 in Wirkverbindung stehen, und der Rotationszylinder 5 mit einer Antriebswelle 6 drehfest verbunden ist, wobei die Antriebswelle 6 mit einem Sonnenrad 7 drehfest verbunden ist. Das Sonnenrad 7 treibt über Planetenräder 8 ein Hohlrad 9 an, über welches eine nicht gezeigte Trommel eines Fahrmischers angetrieben wird. Die Axialkraft, welche vom Verteiler 10 auf den Rotationszylinder 5 wirkt, wird über ein Lager 1 1 in ein weiteres Gehäuseteil 12 eingeleitet, welches direkt das Gehäuse des Untersetzungsgetriebes und den Sockel bildet. Ein Gehäuseteil 13 beinhaltet den Verteiler 10 und ist über nicht gezeigte Verbindungselemente, wie beispielsweise Schrauben, mit der Kurvenscheibe 2 dreh- und ortsfest verbunden. Zusätzlich ist das Gehäuseteil 13 über nicht gezeigte weitere Verbindungselemente, wie beispielsweise Schrauben, mit dem weiteren Gehäuseteil 12 dreh- und ortsfest verbunden, wobei diese Schrauben die Kurvenscheibe 2 durchdringen. Die Antriebswelle 6 weist am Lager 1 1 einen Bund 14 auf, an welchem der Innenring 15 des Lagers 1 1 in axialer Richtung anliegt. Es besteht auch die Möglichkeit, statt dem Bund 14 einen Sicherungsring zu verwenden. Zusätzlich wird die Antriebswelle 6 über einen Sicherungsring 16 in axialer Richtung am Rotationszylinder 5 gehalten. Dadurch ist gewährleistet, dass bei einer Demontage des Radialkolbenmotors vom Untersetzungsgetriebe der Innenring 15, die Antriebswelle 6 und der Rotationszylinder 5 eine Baueinheit bilden. Zusätzlich weist der Rotationszylinder 5 einen in Fig. 2 gezeigten Anschlag auf, an welchem sich der Rotationszylinder 5 an der Kurvenscheibe 2 abstützt. Da die Kurvenscheibe 2 und das Gehäuseteil 14 verbunden sind, der Rotationszylinder 5 sich an der Kurvenscheibe 2 abstützt, kann der Radialkolbenmotor 1 im Servicefall als komplette Baueinheit, d. h., Gehäuseteil 13, Verteiler 10, Antriebswelle 6, Innenring 15, Rotationszylinder 5 und Kurvenscheibe 2, demontiert werden, ohne dass der Radialkolbenmotor 1 in seine Einzelteile zerfällt.A hydraulic radial piston motor 1 has a cam disk 2, which are in operative connection via rollers 3 and piston 4 with a rotary cylinder 5, and the rotary cylinder 5 is rotatably connected to a drive shaft 6, wherein the drive shaft 6 is rotatably connected to a sun gear 7. The sun gear 7 drives via planet gears 8 a ring gear 9, via which a drum, not shown, of a truck mixer is driven. The axial force which acts from the distributor 10 on the rotary cylinder 5 is introduced via a bearing 1 1 in a further housing part 12, which directly forms the housing of the reduction gear and the base. A housing part 13 includes the distributor 10 and is connected via connecting elements, not shown, such as screws, with the cam 2 rotatably and fixedly connected. In addition, the housing part 13 via not shown further connecting elements, such as screws, with the other housing part 12 rotatably and fixedly connected, said screws penetrate the cam 2. The drive shaft 6 has at the bearing 1 1 a collar 14 on which the inner ring 15 of the bearing 1 1 rests in the axial direction. It is also possible to use a circlip instead of the collar 14. In addition, the drive shaft 6 is held via a securing ring 16 in the axial direction on the rotary cylinder 5. This ensures that that at a disassembly of the radial piston motor from the reduction gear, the inner ring 15, the drive shaft 6 and the rotary cylinder 5 form a structural unit. In addition, the rotary cylinder 5 a stop shown in Fig. 2, on which the rotary cylinder 5 is supported on the cam 2. Since the cam 2 and the housing part 14 are connected, the rotary cylinder 5 is supported on the cam 2, the radial piston motor 1 in case of service as a complete unit, ie, housing part 13, distributor 10, drive shaft 6, inner ring 15, rotary cylinder 5 and 2 cam , Disassembled without the radial piston engine 1 decomposes into its individual parts.
Zwischen dem Gehäuseteil 13 und dem Verteiler 10 sind Federn 21 angeordnet, welche den Verteiler 10 auf den Rotationszylinder 5 drücken. Im demontierten Zustand drücken somit diese Federn den Rotationszylinder 5 auf die Kurvenscheibe 2, wodurch der Rotationszylinder 5 in einer festen Position zur Kurvenscheibe 2 verbleibt. Wird der Radialkolbenmotor 1 wieder auf das weitere Gehäuseteil 12 montiert, so wird der Rotationszylinder 5 durch das Lager 1 1 wieder entgegen der Federkraft der Feder 21 zurückgedrückt und der Rotationszylinder 5 liegt in axialer Richtung nicht mehr an der Kurvenscheibe 2 an.Between the housing part 13 and the distributor 10 springs 21 are arranged, which press the distributor 10 onto the rotary cylinder 5. In the disassembled state, these springs thus press the rotary cylinder 5 onto the cam disk 2, as a result of which the rotary cylinder 5 remains in a fixed position relative to the cam disk 2. If the radial piston engine 1 is again mounted on the further housing part 12, then the rotary cylinder 5 is pushed back against the spring force of the spring 21 by the bearing 11 and the rotary cylinder 5 no longer abuts the cam disk 2 in the axial direction.
Fig. 2:Fig. 2:
Der Rotationszylinder 5 weist eine Nut mit einem Sicherungsring 17 auf, welcher eine Scheibe 18 in axialer Richtung sichert. Die Scheibe 18 weist einen Bund 19 auf, welcher im demontierten Zustand des Radialkolbenmotors 1 an den inneren Kurven der Kurvenscheibe 2 anliegt und so die axiale Bewegung des Rotationszylinders 5 entlang seiner Rotationsachse 20 begrenzt.The rotary cylinder 5 has a groove with a retaining ring 17, which secures a disc 18 in the axial direction. The disc 18 has a collar 19, which rests in the disassembled state of the radial piston motor 1 on the inner curves of the cam plate 2 and so limits the axial movement of the rotary cylinder 5 along its axis of rotation 20.
Zwischen dem Rotationszylinder 5 und dem Lager 1 1 kann auch eine Scheibe 22 zum Erzeugen von Drehzahlimpulsen angeordnet sein. Fig. 3:Between the rotary cylinder 5 and the bearing 1 1, a disc 22 may be arranged for generating speed pulses. 3:
Der Radialkolbenmotor 1 nach der Fig. 3 unterscheidet sich vom Radialkolbenmotor 1 nach der Fig. 1 dadurch, dass nicht der Rotationszylinder 5 über einen Bund 19 in der Fig. 1 an der Kurvenscheibe 2 anliegt, sondern zur Demontage des Radialkolbenmotors 1 eine Schraube 23 das Gehäuseteil 13 durchdringt und in die Antriebswelle 6 eingeschraubt wird. Das Gehäuseteil 13 kann einstückig oder mehrstückig ausgeführt sein. Die Schraube 23 liegt mit ihrem Schraubenkopf am Gehäuse 13 an, wodurch die Antriebswelle 6, und mit ihr der Innenring 15, und der Rotationszylinder 5 in Richtung Verteiler 10 gezogen werden. Da die Kurvenscheibe 2 über Verbindungselemente mit dem Gehäuseteil 13 verbunden ist, kann der Radialkolbenmotor 1 vom Untersetzungsgetriebe demontiert werden, ohne dass er in seine Einzelteile zerfällt. Nachdem der Radialkolbenmotor 1 wieder montiert ist, wird die Schraube 23 entfernt, wodurch die Federn 21 den Rotationszylinder 5 wieder auf das Lager 1 1 drücken. Die Schraube 23 kann anschließend zur Verbindung des Gehäuseteils 13 mit dem weiteren Gehäuseteil 12 verwendet werden.The radial piston motor 1 according to FIG. 3 differs from the radial piston motor 1 according to FIG. 1 in that not the rotary cylinder 5 rests against the cam 2 via a collar 19 in FIG. 1, but rather a screw 23 for disassembling the radial piston motor 1 Housing part 13 penetrates and is screwed into the drive shaft 6. The housing part 13 may be made in one piece or in several pieces. The screw 23 rests with its screw head on the housing 13, whereby the drive shaft 6, and with it the inner ring 15, and the rotary cylinder 5 are pulled towards the distributor 10. Since the cam 2 is connected via connecting elements with the housing part 13, the radial piston motor 1 can be dismantled from the reduction gear without it disintegrates into its individual parts. After the radial piston motor 1 is mounted again, the screw 23 is removed, whereby the springs 21 press the rotary cylinder 5 back onto the bearing 1 1.
