Abstract

Die Erfindung bezieht sich auf eine Axialkolbenmaschine (1) mit einem Gehäuse (2), in dessen Gehäuseinnenraum (3) eine Zylindertrommel (5) gelagert ist, in welcher mehrere, etwa axial verlaufende Zylinderbohrungen (6) ausgebildet sind, in welchen Kolben (7) bewegbar geführt sind, die sich über Gleitschuhe (8) an einer um eine Schwenkachse (14) schwenkbare Schwenkscheibe (11) abstützen, mit einer Rückzugeinrichtung (15), an welcher sich die Gleitschuhe (8) bei der Rückzugbewegung der Kolben (7) abstützen, und die einen Abstand (ra) von der Schwenkachse (14) aufweist, und mit wenigstens einem am Gehäuse angeordneten Stützteil (31) zum Abstützen der Rückzugeinrichtung (15) am Gehäuse (2), wobei das Stützteil (31) im Bereich der Schwenkachse (14) der Schwenkscheibe (11) zumindest auf der Seite der Axialkolbenmaschine (1) angeordnet ist, auf der die Kolben (7) einen Saughub ausführen. Das Stützteil (31) weist einen von der Rückzugeinrichtung (15) beabstandeten Anschlag (36) auf, wobei der axiale Abstand (a) zwischen der Rückzugeinrichtung (15) und dem Anschlag (36) im wesentlichen unabhängig vom Schwerkwinkel der Schwenkscheibe (11) ist.

Figure 00000001
The invention relates to an axial piston machine (1) with a housing (2), in the housing interior (3) of which a cylinder drum (5) is mounted, in which a plurality of approximately axially extending cylinder bores (6) are formed, in which piston (7 ) are movably guided, which are supported by slide shoes (8) on a swivel disk (11) which can be pivoted about a swivel axis (14), with a retraction device (15) on which the slide shoes (8) engage when the pistons (7) retract. support, and which has a distance (ra) from the pivot axis (14), and with at least one support part (31) arranged on the housing for supporting the retraction device (15) on the housing (2), the support part (31) in the region of The swivel axis (14) of the swivel plate (11) is arranged at least on the side of the axial piston machine (1) on which the pistons (7) perform a suction stroke. The support part (31) has a stop (36) spaced from the retraction device (15), the axial distance (a) between the retraction device (15) and the stop (36) being essentially independent of the center of gravity of the swivel plate (11) .
