Abstract

Die Erfindung betrifft eine hydrostatische Kolbenmaschine (1) mit einer Triebwelle (2), die eine Zylindertrommeleinheit durchdringt. In der Zylindertrommeleinheit sind Zylinderausnehmungen (18, 19) angeordnet. Mit der Triebwelle (2) sind drehfest Kolben (16, 17) verbunden, welche in den Zylinderausnehmungen (18, 19) verschieblich angeordnet sind. Die Zylindertrommeleinheit ist auf einem an der Triebwelle (2) vorgesehenen Lager (32, 32') zentriert. Die Zylindertrommeleinheit besteht aus einer Zylindertrommel (20, 21) mit mehreren darin ausgebildeten Zylinderausnehmungen (18, 19).The invention relates to a hydrostatic piston machine (1) with a drive shaft (2), which penetrates a cylinder drum unit. In the cylinder drum unit cylinder recesses (18, 19) are arranged. With the drive shaft (2) are non-rotatably connected pistons (16, 17), which are arranged displaceably in the cylinder recesses (18, 19). The cylinder drum unit is centered on a bearing (32, 32 ') provided on the drive shaft (2). The cylinder drum unit consists of a cylinder drum (20, 21) with a plurality of cylinder recesses (18, 19) formed therein.
