GUARNICION DE FRICCION PARA UN EMBRAGUE CON RANURAS

LA INVENCION SE REFIERE A UNA GUARNICION DE FRICCION QUE LLEVA UNA SUPERFICIE DE FRICCION ANULAR DESTINADA A APOYARSE AXIALMENTE CONTRA UNA SUPERFICIE DE REACCION, DEL TIPO EN LA QUE LA SUPERFICIE DE FRICCION LLEVA UNA RED DE RANURAS PARA PERMITIR LA CIRCULACION DE UN LIQUIDO ENTRE LA GUARNICION (38) Y LA SUPERFICIE DE REACCION, CARACTERIZADA PORQUE LA RED DE RANURAS NO DESEMBOCA RADIALMENTE HACIA EL EXTERIOR (51) DE LA GUARNICION (38). The friction lining for a torque converter clutch is made from a carbon composition material and designed to make contact with a reaction surface (40). It has a series of concentric (54,56) and radial (58,60) grooves in its surface for circulating a liquid between the clutch lining and reaction surface. One set of radial grooves (60) connects with an inner annular groove (54), while the other set (58), located between the two annular grooves, is offset relative to the first set in a peripheral direction, and non of the grooves emerge radially outside the lining. In a variant of the design the lining can have a spiral groove with a series of radial grooves connecting the spirals.
