Abstract
Offenbart ist eine Axialkolbenmaschine mit zumindest einer Schrägscheibe, an der eine Zylindertrommel abgestützt ist, in der im Wesentlichen kegelige Kolben geführt sind, die mit einer Welle in Wirkverbindung stehen und schräg nach außen zur Wellenachse angestellt sind.Disclosed is an axial piston machine with at least one swash plate on which a cylinder drum is supported, in which essentially conical pistons are guided, which are in operative connection with a shaft and are inclined outwardly to the shaft axis.
Description
Die Erfindung betrifft eine Axialkolbenmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an axial piston machine according to the preamble of patent claim 1.
Eine derartige Axialkolbenmaschine ist beispielsweise aus der DE PS 1 162 194 bekannt. Diese Axialkolbenmaschine hat ein Gehäuse, das einen Innenraum begrenzt, in dem zwei Schrägscheiben drehfest gelagert sind. In den Innenraum ragt eine Antriebswelle, die einen Antriebsflansch hat, an dessen entgegengesetzten Stirnflächen jeweils eine Kolbenreihe angeordnet ist, die aus einer Vielzahl von Kolben besteht, die jeweils in einer Zylinderhülse einer sich an den Schrägscheiben abstützenden Zylindertrommel geführt sind. Die Kolben sind zylindrisch ausgebildet und haben jeweils eine schräg zur Wellenachse angestellte Kolbenachse, wobei die Kolbenachsen der Kolben der einzelnen Kolbenreihen parallel zueinander verlaufen. Nachteilig an dieser Axialkolbenmaschine ist, dass ein maximaler Anstellwinkel der jeweiligen Schrägscheiben durch die Schrägstellung der Zylinderhülsen begrenzt ist.A Such axial piston machine is for example from DE PS 1 162 194 known. This axial piston machine has a housing that limited an interior in which two swash plates rotatably mounted are. In the interior protrudes a drive shaft, which has a drive flange has, at its opposite end faces in each case a row of pistons is arranged, which consists of a plurality of pistons, respectively in a cylinder sleeve one at the swash plates supporting Cylinder drum guided are. The pistons are cylindrical and have each an oblique to the shaft axis employed piston axis, wherein the piston axes the pistons of the individual rows of pistons run parallel to one another. A disadvantage of this axial piston machine is that a maximum Angle of the respective swash plates by the inclination the cylinder sleeves is limited.
Die WO 03/058034 A1 schlägt eine Axialkolbenmaschine mit konischen Kolben vor, die einen definierten Konuswinkel haben und deren Kolbenachsen parallel zur Wellenachse verlaufen. Nachteilig an dieser Lösung ist jedoch, dass die maximalen Anstellwinkel der Schrägscheiben durch den Konuswinkel der Kolben beschränkt sind, da dann im inneren Totpunkt die Kolben mit ihren Kolbenschäften an einer Mantellinie der jeweiligen Zylinderhülse anliegen.The WO 03/058034 A1 proposes an axial piston machine with conical pistons in front, which defines a Cone angle and their piston axes parallel to the shaft axis run. The disadvantage of this solution, however, is that the maximum Inclination angle of the swash plates are limited by the cone angle of the piston, because then at the inner dead center the pistons with their piston stems abut against a generatrix of the respective cylinder sleeve.
Aufgabe der vorliegenden Erfindung ist es, eine Axialkolbenmaschine zu schaffen, die einen vergrößerten Anstellwinkel und somit ein größeres maximales Fördervolumen ermöglicht.task the present invention is to provide an axial piston machine, the one increased angle of attack and thus a larger maximum delivery allows.
Diese Aufgabe wird gelöst durch eine Axialkolbenmaschine mit den Merkmalen des Patentanspruchs 1.These Task is solved by an axial piston machine having the features of the patent claim 1.
Die erfindungsgemäße Axialkolbenmaschine hat zumindest eine Schrägscheibe, an der eine Zylindertrommel abgestützt ist. In der Zylindertrommel sind Kolben geführt, die mit einer Welle in Wirkverbindung stehen. Die Drehachse der Zylindertrommel ist zur Wellenachse angestellt. Erfindungsgemäß sind die Kolben im Wesentlichen kegelig mit einem radial erweiterten Kolbenkopf ausgeführt und mit ihrer Kolbenachse mit Bezug zur Wellenachse um einen Kolbenachsenwinkel schräg nach außen angestellt, so dass ein Teilkreis, auf dem Kolbenfüße der Kolben liegen, kleiner ist als ein Teilkreis, auf dem die Kolbenköpfe liegen. Die im Wesentlichen kegelige Ausführung der Kolben mit der Schrägstellung nach außen hat den Vorteil, dass im inneren Totpunkt ein Anliegen der Zylinderhülsen mit ihren Mantellinien an den Kolbenschäften erst bei einem, im Vergleich zu den eingangs erwähnten Axialkolbenmaschinen, größeren Anstellwinkel auftritt.The has axial piston machine according to the invention at least one swashplate, on which a cylinder drum is supported. In the cylinder drum are Piston guided, which are in operative connection with a shaft. The axis of rotation of Cylinder drum is adjusted to the shaft axis. According to the invention Piston substantially conical with a radially extended piston head accomplished and with its piston axis with respect to the shaft axis about a piston axis angle aslant outward adjusted, so that a pitch circle, lie on the piston feet of the piston, is smaller than a circle on which the piston heads lie. The essentially conical design of the piston with the inclination outward has the advantage that at the inner dead center a concern of the cylinder sleeves with their generatrices on the piston stems only at one, in comparison to the aforementioned Axial piston machines, larger angle of attack occurs.

Um die Kolben dichtend in den Zylinderhülsen zu führen, können ihre Kolbenköpfe kugelig ausgeführt sein.Around To guide the piston sealingly in the cylinder sleeves, their piston heads can be spherical accomplished be.
Weiterhin können die Kolben einen Gewindeabschnitt zum Einschrauben in eine entsprechende Gewindebohrung des Antriebsflansches haben. Alternativ können die Kolben mit ihren Kolbenfüßen in entsprechende Bohrungen des Antriebsflansches eingepresst sein.Farther can the pistons a threaded portion for screwing into a corresponding Threaded hole of the drive flange have. Alternatively, the Pistons with their piston feet in corresponding Be drilled holes in the drive flange.
