Abstract
Es handelt sich um einen fluidbetätigten kolbenstangenlosen Linearantrieb, mit einem Gehäuse (2), in dem eine Laufkammer (6) vorgesehen ist, in der sich ein Kolben (13) befindet. Außerhalb der Laufkammer (6) ist ein mit dem Kolben (13) verbundenes Abtriebsteil (16) vorgesehen. Zwischen dem Gehäuse (2) und dem Abtriebsteil (16) wirkt eine Bremseinrichtung (34), die eine außerhalb der Laufkammer (6) drehgelagerte Gewindespindel (35) aufweist. Die Gewindespindel (35) steht mit einem am Abtriebsteil (16) vorgesehenen Muttergewinde (42) in Eingriff. Am einen Endbereich des Gehäuses (2) befindet sich eine mit einer spindelfesten Bremspartie (46) der Gewindespindel (35) zusammenarbeitende Bremseinheit (44). It is a fluid-actuated linear actuator without a piston rod, with a housing (2) in which a running chamber (6) is provided, in which a piston (13) is located. An output part (16) connected to the piston (13) is provided outside the running chamber (6). A braking device (34) acts between the housing (2) and the driven part (16) and has a threaded spindle (35) which is rotatably mounted outside the running chamber (6). The threaded spindle (35) engages with a nut thread (42) provided on the driven part (16). At one end area of the housing (2) there is a brake unit (44) which cooperates with a spindle-fixed brake part (46) of the threaded spindle (35).
