Abstract

An adjusting and centering contrivance for a servo brake including a U-shaped, fixed guide casing (1) and in the axial borings of which is journaled a slide-through lock that is mounted in an axially displaceable fashion out from a central position against the force of a centering spring (15). The slide-through lock comprises two threaded bolts (3) that are screwed into an adjustment tube (5). Firmly disposed, axially symmetrical hereto is an adjustment gear (17) and which engages an adjustment lever (19). The adjustment lever (19) that is pivotable about a bolt (21) and is swivelled outwardly and brought back to its initial position by means of a separate reset (return) spring via a stop (33) during a slide-through movement of the slide-through lock. In order to obtain an adjusting and centering contrivance with increased operation safety and performance without thereby enlarging the stressed structural space, return of the pivoting lever (19) is undertaken solely by means of the centering spring (15). Additionally provided is an actuation add-on piece (37) that is capable of moving along with the slide-through lock and that cooperates with another stop (35) acting in the opposing…
