Abstract

Die Erfindung beschreibt einen Linearverstellantrieb (1), insbesondere eine mit einem Druckmedium beaufschlagbare, doppelt wirkende Zylinder-Kolbeneinheit (2). Diese weist eine rohrförmige Kolbenstange (14) auf, die eine in einer Lageranordnung eines Endgehäuses (9) drehbar gelagerte Gewindespindel (28) konzentrisch umfaßt und mit dieser in Gewindeeingriff steht und die mit einer schaltbaren Sperranordnung (3) zur Blockierung der Drehbewegung zusammenwirkt. In dem stirnseitig am Zylindermantel (4) angeordneten Endgehäuse (9) ist in einer mit einer Mittelachse zu einer Zylinderlängsmittelachse (22) senkrecht verlaufenden Bohrung (36) ein mit dem Druckmedium beaufschlagbarer Sperrkolben (37) verstellbar angeordnet, der mit einem der Zylinderlängsmittelachse (22) zugewandten Sperrfortsatz (38) in Sperrstellung in zumindest eine am Umfang der Gewindespindel (28) bzw. einer mit dieser drehfest verbundenen Sperrhülse (33) angeordnete Sperraufnahme (39) ragt.

The invention relates to a linear adjustment drive (1), in particular a double-acting cylinder-piston unit (2) that can be pressurized with a pressure medium. This has a tubular piston rod (14) which concentrically comprises a threaded spindle (28) rotatably mounted in a bearing arrangement of an end housing (9) and is in threaded engagement therewith and which interacts with a switchable locking arrangement (3) for blocking the rotary movement. In the end housing (9) arranged at the end of the cylinder jacket (4), a blocking piston (37) which can be acted upon by the pressure medium and which is connected to one of the cylinder longitudinal center axes (22 ) facing locking extension (38) in the locking position protrudes into at least one locking receptacle (39) arranged on the circumference of the threaded spindle (28) or a locking sleeve (33) connected to it in a rotationally fixed manner.
