Abstract

Hydraulische Antriebsvorrichtung, insbesondere Drehvorrichtung für Baggergreifer und dergleichen, mit einem feststehenden Bauteil (1) und einem bewegten Bauteil (2), insbesondere einem Stator (1) und einem Rotor (2), mindestens zwei zwischen feststehendem Bauteil (1) und bewegtem Bauteil (2) angeordneten, über mindestens abschnittsweise voneinander getrennte Hydraulikleitungen (11, 19, 22) an gemeinsame Hydraulikanschlüsse (20, 23) anschließbaren Druckkammern (7), die über die Hydraulikanschlüsse (20, 23) in einer solchen Weise abwechselnd und nacheinander mit Hydraulikflüssigkeit druckbeaufschlagbar und dadurch expandierbar sowie entlastbar und komprimierbar sind, daß sich das bewegte Bauteil (2) relativ zum feststehenden Bauteil (1) bewegt, und einer Steuereinrichtung zum Steuern der Zu- und Abfuhr der Hydraulikflüssigkeit in dieser Weise zwischen den Druckkammern (7) und den gemeinsamen Hydraulikanschlüssen (20, 23), wobei zur Integration einer Bremseinrichtung mit geringem konstruktiven Aufwand, geringem Gewicht, wenig Platzbedarf und hoher Funktionssicherheit in einem Abschnitt (11) der Hydraulikleitung mindestens einer Druckkammer (7), den diese nicht mit den anderen Druckkammern (7) gemeinsam hat, eine Absperreinrichtung (33, 39) vorgesehen ist, durch welche ein Abfließen von Hydraulikflüssigkeit aus der Druckkammer (7) zumindest weitgehend verhindert wird.
