Abstract

An integrated manual brake device on a brake actuation unit, particularly for rail vehicles, and it includes a hydraulic or pneumatic cylinder. The brake actuation unit contains a linkage setter including two parts displaceable relative to each other in a telescopic fashion. One of the parts is formed as a threaded spindle and the other tubular part is firmly connected with a nut which is screwed on the spindle with a nonselflocking thread. A stop is provided on the tubular part fixed in an axial direction but easily turnable. An actuating spring is clamped between the piston and the output part.
