Abstract

Die Erfindung betrifft eine hydrostatische Axialkolbenmaschine (1) in Schrägachsenbauweise mit einer um eine Rotationsachse (Rt) drehbar innerhalb eines Gehäuses (2) angeordneten Triebwelle (4), mit einem um eine Rotationsachse (Rt) drehbar innerhalb des Gehäuses (2) angeordneten Triebflansch (3), und mit 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 zur gelenkigen Befestigung der Kolben (10) an dem Triebflansch (3) jeweils eine Kugelgelenkverbindung (20) vorgesehen ist, die aus einer kugelkalottenförmigen Aufnahmeschale (3a) in einer Stirnseite (3b) des Triebflansches (3) und einem Kugelkopf (10b) gebildet ist, der mit dem Kolben (10) in Wirkverbindung steht. Erfindungsgemäß sind die Aufnahmeschalen (3a) jeweils als sich bis zu dem Kugeläquator erstreckende Halbkugeln ausgebildet und ist an einer Stirnseite (3b) des Triebflansches (3) im Bereich der Aufnahmeschalen (3a) ein Rückhaltesteg (30) ausgebildet, der sich über den Kugeläquator der Halbkugel erstreckt, um den Kugelkopf (10b) mit einem Winkel von größer 180° Grad zu umgreifen.

The invention relates to a hydrostatic axial piston machine (1) in a bent-axis design with a about a rotational axis (R t ) rotatably within a housing (2) arranged drive shaft (4), with a about an axis of rotation (R t ) rotatably disposed within the housing (2) Drive flange (3), and with a about an axis of rotation (R z ) rotatably within the housing (2) of the axial piston machine (1) arranged cylindrical drum (7), wherein the cylinder drum (7) is provided with a plurality Kolbenausnehmungen (8), in which in each case a piston (10) is arranged longitudinally displaceable, wherein the pistons (10) are hinged to the drive flange (3) and for articulated attachment of the piston (10) on the drive flange (3) is provided in each case a ball joint connection (20) from a spherical cap-shaped receiving tray (3a) in an end face (3b) of the drive flange (3) and a ball head (10b) is formed, which is in operative connection with the piston (10). According to the invention, the receiving shells (3a) are each formed as hemispheres extending up to the ball equator, and a retaining web (30) is formed on an end face (3b) of the drive flange (3) in the region of the receiving shells (3a) Hemisphere extends to engage around the ball head (10b) at an angle greater than 180 degrees.
