Abstract

Die Erfindung bezieht sich auf eine hydrostatische Axialkolbenmaschine (1) mit einer in einem Gehäuse (2) gelagerten Zylindertrommel, in der in Zylinderbohrungen Kolben verschiebbar gelagert sind, deren Kolbenenden an einer drehbar gelagerten Antriebsscheibe schwenkbar abgestützt sind, wobei die Zylindertrommel und eine an der der Antriebsscheibe abgewandten Seite der Zylindertrommel angeordnete Steuerscheibe (18) durch eine in einer Schwenkebene (22) quer verschwenkbar ist, wobei die Steuerscheibe (18) an ihrer der Zylindertrommel abgewandten Seite eine längs der Schwenkebene (22) kreisbogenförmig gekrümmte Lagergleitfläche (27) aufweist, an der eine Zwischenscheibe (25) mit einer entsprechend gekrümmten Lagergleitfläche (28) gelagert ist, wobei eine Nachführvorrichtung (31) vorgesehen ist, die eine relative Verschiebung zwischen der Steuerscheibe (18) und der Zwischenscheibe (25) herbeiführt, und wobei die Zwischenscheibe (25) mit Steuerkanälen in der Steuerscheibe (18) korrespondierende Steuerschlitze (S1, S2) aufweist. Zwecks Verbesserung der Bewegungssteuerung der Zwischenscheibe (25) relativ zur Steuerscheibe (18) ist die Nachführvorrichtung (31) über den gesamten Schwenkbereich der Steuerscheibe (18) so wirksam, daß der Verschiebeweg der Steuerscheibe (18) größer ist als der Verschiebeweg der Zwischenscheibe.

The invention relates to a hydrostatic axial piston machine (1) with a cylinder drum mounted in a housing (2), in which pistons are slidably mounted in cylinder bores, the piston ends of which are pivotally supported on a rotatably mounted drive disk, the cylinder drum and one on the On the side of the cylinder drum facing away from the drive disk, the control disk (18) can be pivoted transversely in a pivot plane (22), the control disk (18) on its side facing away from the cylinder drum having a bearing sliding surface (27) curved in a circular arc along the pivot plane (22) one intermediate washer (25) is mounted with a correspondingly curved bearing sliding surface (28), a tracking device (31) is provided which brings about a relative displacement between the control disk (18) and the intermediate washer (25), and the intermediate washer (25 ) with control channels in the control disc (18) ko Corresponding control slots (S1, S2). In order to improve the movement control of the intermediate disk (25) relative to the control disk (18), the tracking device (31) is so effective over the entire swiveling range of the control disk (18) that the displacement path of the control disk (18) is greater than the displacement path of the intermediate disk.
