Description

Die Erfindung bezieht sich auf hydraulische Motoren derjenigen Art, bei denen ein von einer Pumpe, gegebenenfalls unter Zwischenschaltung eines Druckkessels, kommender Flüssigkeitsstrom mittels hydraulischer Arbeitszylinder einen hydraulischen Rotor in Drehbewegung versetzt. Beispielsweise sind bei derartigen Motoren die Arbeitszylinder in einer umlaufenden Trommel parallel axial angeordnet und wirken, von einem Steuerschieber wechselweise beaufschlagt, auf eine Schrägscheibe, so daß auf die Trommel ein Drehmoment ausgeübt wird. Es sind ferner Motoren bekannt, bei denen die in einem feststehenden Gehäuse verschiebbaren Arbeitskolben radial auf eine Exzenterscheibe der Abtriebswelle einwirken. Um nun bei gleichbleibender Leistung bei kleinerer Drehzahl das Drehmoment entsprechend erhöhen zu können, - sind erfindungsgemäß entweder mehrere achsparallele Reihen von Arbeitszylindern gleichen Durchmessers auf verschiedenen Teilkreisen einer an sich' bekannten Schrägscheibe angeordnet, oder es wirken mehrere Sterngruppen von Arbeitszylindern gleichen Durchmessers auf Exzenterscheiben verschiedenen Durchmessers einer gemeinsamen Abtriebswelle ein, wobei sie wahlweise nacheinander oder gleichzeitig wirksam sind. Entsprechend können mehrere Gruppen von Arbeitszylindern verschiedenen Durchmessers auf dem gleichen Teilkreis einer Schrägscheibe oder auf Exzenterscheiben gleichen Durchmessers einer gemeinsamen Abtriebswelle gruppenweise nacheinander oder gleichzeitig wirksam sein.The invention relates to hydraulic motors of the type where a pump, possibly with the interposition of a pressure vessel, incoming liquid flow by means of hydraulic working cylinder a hydraulic Rotor set in rotation. For example, in such engines, the working cylinders Axially arranged in parallel in a rotating drum and act from a control slide alternately acted upon on a swash plate, so that a torque is applied to the drum is exercised. There are also motors known in which the in a fixed Housing displaceable working piston radially on an eccentric disk of the output shaft act. In order to increase the torque while maintaining the same output at a lower speed to be able to increase accordingly, - are according to the invention either several axially parallel Rows of working cylinders of the same diameter on different pitch circles a swashplate known per se, or several groups of stars act of working cylinders of the same diameter on eccentric disks of different diameters a common output shaft, either one after the other or simultaneously are effective. Correspondingly, several groups of working cylinders can be different Diameter on the same pitch circle of a swash plate or on eccentric disks the same diameter of a common output shaft in groups one after the other or be effective at the same time.

Durch das gleichzeitige Wirksamwerdenlassen von Arbeitszylindern verschiedener Stufen werden neue Übertragungsstufen gebildet. Sind z. B. drei Gruppen von gleichen Zylindern verschiedener Exzentrizität vorhanden, so lassen sich entsprechend den vorhandenen Kombinationsmöglichkeiten sieben verschiedene Arbeitsstufen erzeugen. Die beliebige Zusammenschaltung verschiedener Zylindergruppen mittels eines Steuergliedes kann ohne erfinderischen Aufwand auf rein konstruktivem Wege erfolgen.Through the simultaneous activation of working cylinders of different Levels, new levels of transmission are formed. Are z. B. three groups of the same Cylinders of different eccentricity are available, so can be according to the create seven different work stages. The arbitrary interconnection of different cylinder groups by means of a control element can be done in a purely constructive way without inventive effort.

Ausführungsbeispiele sind in den Abbildungen dargestellt.Exemplary embodiments are shown in the figures.

In Abb. i ist ein Schrägscheibenmotor mit achsparalleler Anordnung der Arbeitszylinder dargestellt. In einem feststehenden Gehäuse i ist eine Kolbentrommel 2 drehbar angeordnet, die unmittelbar mit dem Abtrieb 3 verbunden ist. Innerhalb der Trommel 2 sind auf verschiedenen Teilkreisen Gruppen 4 und 5 von Arbeitszylindern gleichen Durchmessers angeordnet, die über die als Steuerschieber ausgebildete Trommellagerung wechselweise mit der Druckflüssigkeitszuleitung 6 oder der Flüssigkeitsableitung 7 verbunden werden. Die Arbeitskolben 4, 5 wirken über eine Lagerscheibe 8 auf ein entsprechendes Schräglager 9 des Gehäuses i.In Fig. I is a swash plate motor with an axially parallel arrangement the working cylinder shown. In a stationary housing i is a piston drum 2 rotatably arranged, which is directly connected to the output 3. Within of the drum 2 are groups 4 and 5 of working cylinders on different pitch circles the same diameter arranged over the drum bearing designed as a control slide alternately with the hydraulic fluid supply line 6 or the fluid discharge line 7 can be connected. The working pistons 4, 5 act on a bearing disk 8 corresponding angular contact bearing 9 of the housing i.

Je nach der Stellung des Steuerschiebers io werden entweder die auf dem inneren Teilkreis befindliehen Zylinder 4 oder die Zylinder 5 des äußeren Teilkreises beaufschlagt, wodurch infolge des verschiedenen Hubes der Arbeitskolben die Drehzahl und damit das Drehmoment beeinflußt werden können.Depending on the position of the spool io, either the the inner pitch circle is located cylinder 4 or the cylinder 5 of the outer pitch circle acted upon, whereby the speed due to the different stroke of the working piston and thus the torque can be influenced.

Durch Verschieben des Steuerschiebers io innerhalb des Gehäuses können abwechselnd entweder die Zylinder 4 oder 5 mit der Zu- und Ableitung 6, 7 verbunden werden (nicht gezeichnet).By moving the control slide io within the housing you can alternately either the cylinders 4 or 5 are connected to the inlet and outlet lines 6, 7 are (not drawn).

In Abb. 2 ist ein hydraulischer Motor dargestellt, in welchem die Arbeitskolben sternförmig in zwei Ebenen liegen und auf verschiedene Exzenter der Abtriebswelle wirken. Die Arbeitszylinder i i und 12 haben gleichen Durchmesser und sind verschiebbar in dem Gehäuse 13 angeordnet. Die Zuführung der Druckflüssigkeit erfolgt während des Druckhubes über Anschluß 14 sowie über eine Zuführung 15; während des Rückhubes der Arbeitskolben wird di; Flüssigkeit über eine entsprechende Ableitung 16 und Leitung 17 abgeführt. Die Kolben i i und 12 stützen sich auf Exzentern 18 und i.9 ab, die auf einer in Teil 13 gelagerten Abtriebswelle 2o angeordnet sind. Teil 13 ist in dem äußeren Gehäuse 2i verschiebbar gelagert, so daß entweder die Kolben 12 oder die Kolben i i mit den Flüssigkeitsleitungen 14 bzw. 17 in Verbindung gebracht werden können. In an sich bekannter Weise werden die Zu- und Ableitungen 15 und 16 über einen nicht gezeichneten, bekannten Steuerschieber mit der Pumpe verbunden.In Fig. 2 a hydraulic motor is shown in which the working pistons lie in a star shape in two planes and act on different eccentrics of the output shaft. The working cylinders ii and 12 have the same diameter and are arranged displaceably in the housing 13. The pressure fluid is supplied during the pressure stroke via connection 14 and via a feed 15; during the return stroke of the working piston is di; Liquid discharged via a corresponding discharge line 16 and line 17. The pistons ii and 12 are supported on eccentrics 18 and i.9, which are arranged on an output shaft 2o mounted in part 13. Part 13 is slidably mounted in the outer housing 2i, so that either the pistons 12 or the pistons ii can be brought into connection with the liquid lines 14 and 17, respectively. In a manner known per se, the supply and discharge lines 15 and 16 are connected to the pump via a known control slide (not shown).

Ein drittes Ausführungsbeispiel ist in Abb. 3 dargestellt, die einen Querschnitt durch die Trommel 22 einer Axialpumpe mit Schrägscheibe entsprechend Abb. i darstellt. Hier sind konzentrisch zur Trommel zwei Gruppen Arbeitskolben 23 bzw. 24 dargestellt, die entweder nacheinander oder gleichzeitig vom Druckmittel beaufschlagt werden.A third embodiment is shown in Fig. 3, the one Cross-section through the drum 22 of an axial pump with a swash plate accordingly Fig.i represents. Two groups of working pistons are concentric to the drum 23 and 24 shown, either one after the other or simultaneously from the pressure medium be applied.
