Abstract

Die Erfindung betrifft eine hydrostatische Axialkolbenmaschine (1) in Schrägachsenbauweise mit einer um eine Rotationsachse (Rt) drehbar innerhalb eines Gehäuses (2) angeordneten Triebwelle (4), die mit einem Triebflansch (3) versehen ist, und einer um eine Rotationsachse (Rz) drehbar innerhalb des Gehäuses (2) der Axialkolbenmaschine (1) angeordneten Zylindertrommel (7), wobei die Zylindertrommel (7) mit mehreren Kolbenausnehmungen (8) versehen ist, in denen jeweils ein Kolben (10) längsverschiebbar angeordnet ist, wobei die Kolben (10) an dem Triebflansch (3) gelenkig befestigt sind, und wobei zwischen der Triebwelle (4) und der Zylindertrommel (7) ein Mitnahmegelenk (30) zur Mitnahme der Zylindertrommel (7) angeordnet ist, wobei das Mitnahmegelenk (30) zumindest einen als Gleitkörper oder als Wälzkörper ausgebildeten Mitnahmekörper (M1; M2; M3; M4) aufweist, der in der Triebwelle (4) und der Zylindertrommel (7) abgestützt ist. Erfindungsgemäß ist eine Schmiereinrichtung (80) für das Mitnahmegelenk (30) vorgesehen, mittels der dem Mitnahmekörper (M1; M2; M3; M4) Schmiermittel zur Kühlung und Schmierung des Mitnahmekörpers (M1; M2; M3; M4) von einem am Gehäuse (2) der Axialkolbenmaschine (1) angeordneten Schmiermittelanschluss (81) zuführbar ist.

The invention relates to a hydrostatic axial piston machine (1) in bent-axis design with a about a rotational axis (R t ) rotatably within a housing (2) arranged drive shaft (4) which is provided with a drive flange (3), and one about an axis of rotation (R z ) rotatably within the housing (2) of the axial piston machine (1) arranged cylinder drum (7), wherein the cylinder drum (7) with a plurality Kolbenausnehmungen (8) is provided, in each of which a piston (10) is arranged longitudinally displaceable, wherein the piston (10) are hinged to the drive flange (3), and wherein between the drive shaft (4) and the cylinder drum (7) a driving joint (30) for driving the cylinder drum (7) is arranged, wherein the driving joint (30) at least one has a driving body (M1, M2, M3, M4), which is supported in the drive shaft (4) and the cylinder drum (7). According to the invention, a lubrication device (80) for the driving joint (30) is provided by means of which the driving body (M1; M2; M3; M4) has lubricant for cooling and lubricating the driving body (M1; M2; M3; M4) from a housing (2) ) of the axial piston machine (1) arranged lubricant connection (81) can be fed.
