DEVICE AND METHOD FOR ADJUSTING THE TORQUE TRANSMITTED BY A FRICTION CLUTCH

A device for setting the torque transmitted by a friction clutch ( 12 ), having an actuator chain which comprises an electric motor ( 45 ), a step-down gear ( 42 ) and a mechanism for converting the rotational movement into a displacement of a pressure plate ( 29 ) of the clutch ( 12 ), so as to ena...

Beschreibung
Zusammenfassung:	A device for setting the torque transmitted by a friction clutch ( 12 ), having an actuator chain which comprises an electric motor ( 45 ), a step-down gear ( 42 ) and a mechanism for converting the rotational movement into a displacement of a pressure plate ( 29 ) of the clutch ( 12 ), so as to enable the torque which is transmitted to be set precisely and rapidly even given high friction. For this purpose, the electric motor ( 45 ) and/or step-down gear ( 42 ) is/are affected by friction, the conversion mechanism ( 31, 32, 35, 36, 40 ) and/or the friction clutch ( 12 ) itself is/are affected by elasticity, and, to set the torque (Md) of the friction clutch ( 12 ), a position regulator ( 47 ) which is operatively connected to the electric motor ( 45 ) and a sensor ( 46; 46 ') which determines the position of one of the links of the actuator chain ( 45, 42, 41, 40, 36, 35, 32, 31, 29 ) are provided, the sensor being present at a location upstream of a substantial part of the elasticity in the force-flow direction. The corresponding control and calibrating method is also developed.
