FRIZIONE CON PIASTRA DI SPINTA PARTICOLARMENTE PER AUTOVEICOLI

L'invenzione riguarda una frizione in particolare per autoveicoli, con una piastra di spinta collegata in modo solidale alla rotazione con un corpo, ma traslabile limitatamente in senso assiale, e con una molla a tazza attiva fra il corpo e la piastra di spinta. A friction clutch wherein changes in the axial position of the rotary pressure plate in a direction toward the counterpressure plate as a result of wear upon the friction linings between such plates are compensated for by an automatic adjusting system between the diaphragm spring and the pressure plate or between the diaphragm spring and the rear wall of the housing of the friction clutch. The compensating unit employs two concentric rings which can be rotated and thereby moved axially toward the diaphragm spring only when the friction linings have undergone initial wear or upon renewed wear following an adjustment.
