The present invention discloses a spring clutch comprising a coil assembly, a rotor assembly and a pulley assembly. The coil assembly comprises a coil housing, an encapsulated coil and a shell, the encapsulated coil is in the coil housing. The rotor assembly comprises a shaft, a rotor and a sleeve, the sleeve is on the shaft, the shaft is in the rotor, the shaft is in the coil housing. The pulley assembly comprises an armature, leaf springs, a brake plate and a pulley, one side of the leaf spring is pressed with armature and the another side is pressed with pulley, the brake plate is outside of the armature and covered some area of the armature, the pulley is on the sleeve. The brake plate has magnet pieces inside. A spring clutch in accordance with the present invention the brake plate has magnet pieces inside to make the armature has magnetic force to catch up with the brake plate to enable the clutch has strong friction force to reduce the stop time.

A rotor-integrated disconnect clutch for a hybrid module with a rotor, comprising a clutch disc axially arranged to be non-rotatably secured between a counter plate and an axially movable pressure plate, wherein a first lever element such as a diaphragm spring is pivotable about a bearing point and in operative connection with the pressure plate, for instance via a pressure plate tab, to transmit force, wherein an actuator such as an electrical concentric actuator for at least indirectly causes the first element to pivot about the bearing point, wherein a second lever element is disposed between the first actuator and the first lever element to have a force transmitting effect there between. The invention further relates to a drive train including a hybrid module with a disconnect clutch of this type.
