Abstract

Eine Axialkolbenmaschine (1) weist eine drehbar gelagerte Welle (3) und eine an der Welle (3) angeordnete Zylindertrommel (7) auf. In der Zylindertrommel (7) sind Kolben (9) in Zylindern (8) verschiebbar, die sich über Gleitschuhe an einer Schrägscheibe abstützen. Ferner sind eine an den Gleitschuhen (10) angreifende Rückzugeinrichtung und ein Steuerkörper (15) zum zyklischen Verbinden der zylinder (8) mit Druckleitungen vorgesehen. Eine erste Feder (21) ist zwischen der Zylindertrommel (7) und der Rückzugeinrichtung eingespannt, um gleichzeitig die Zylindertrommel (7) gegen den Steuerkörper (15) und die Gleitschuhe gegen die Schrägscheibe vorzuspannen. Zusätzlich ist eine auf die Zylindertrommel (7) einwirkende zweite Feder (30) mit einer progressiven Kennlinie derart vorgesehen, daß die von der zweiten Feder (30) auf die Zylindertrommel (7) in Richtung auf den Steuerkörper (15) ausgeübte Federkraft mit dem Federweg, in die zweite Feder (30) bei einer Verschiebung der Zylindertrommel (7) gegen den Steuerkörper (15) erfährt, überproportional zunimmt.
