Patent ID: 7032733

Claim:
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 a rotational movement into a displacement of a pressure plate ( 29 ) of the clutch ( 12 ), wherein a) the electric motor ( 45 ) and/or step-down gear ( 42 ) is/are affected by friction; b) the mechanism ( 31 , 32 , 35 , 36 , 40 ) for converting the rotational movement into a displacement, and/or the friction clutch ( 12 ) is/are provided structurally with elasticity; and c) 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, d) for which purpose the sensor ( 46 ; 46 ′) is arranged at a location which is situated upstream of a substantial part of the elasticity in the force-flow direction.
