Abstract

A device for setting a relative rotational position of a gearwheel and a ring gear disposed coaxially mounted and turnable on an annular extension of the gearwheel includes a plurality of radially extending pressure levers actuatable in common by an axially adjustable, centrically disposed adjusting element for releasing a spring-biased positive connection of mutually engaging faces of the gearwheel and the ring gear by reducing the spring bias acting upon the faces, the pressure levers being loosely disposed between the annular extension of the gearwheel and a clamping disc adjacent thereto, the pressure levers being received in radial grooves formed in the clamping disc and being pivotally braced at a first contact region located between the ends thereof against one of the annular extension and the clamping disc, the adjusting element being displaceable over a distance, during a first portion of which the spring bias increases from a relatively low value to a value necessary for maintaining the relative rotational position of the gearwheel and the ring gear and, during a second portion of the distance displaceable by the adjusting element, the spring bias necessary for maintainin…
