ABSTRACT:
A brake cylinder has a piston one side of which is spring-loaded and the other side of which is acted upon by a fluid pressure medium. A spindle shaft is coupled t the cylinder by a screw coupling having a non-self-locking thread and is engageable with an actuating rod which is adapted to be connected to the brake linkage. A sleeve is rotatably mounted on the cylinder but is non-axially movable with respect to the cylinder. The sleeve is axially but non-rotatably slideable with respect to the spindle shaft. An overrunning drive is operatively connected between the sleeve and a drive mechanism which is operable exteriorly of the brake cylinder. The drive locks in the driving position when the sleeve rotates in a direction to unscrew the spindle shaft from the piston in the direction to release the brake.
