Thu, 07 Jul 2016 08:00:00 EDTA rotary coupling (200) for an all-wheel drive vehicle includes a housing (210), an input part (212), an output part (214), and a clutch (220) disposed within a clutch area (222) of the housing (210) and is movable between an engaged position and a disengaged position to change an amount of torque transferred from the input part (212) to the output part (214). A fluid reservoir (260) is defined in the housing (210). A lubrication valve (250) is movable between an open position and a closed position for controlling supply of a fluid from the fluid reservoir (260) to the clutch area (222) of the housing (210). An actuator (238) is connected to the clutch (220) to move the clutch (220) between the engaged position and the disengaged position and connected to the lubrication valve (250) to move the lubrication valve (250) between the open position and the closed position.
Thu, 07 Jul 2016 08:00:00 EDTThe invention relates to a friction element (8) comprising a friction lining (12, 13) that is connected to a lining carrier (14, 15), and comprising a carrier element, wherein said lining carrier (14, 15) is connected to the carrier element, and a connecting element (24, 25) is also used to connect the lining carrier (14, 15) to the carrier element, said connecting element being guided through a recess (26, 37) in the lining carrier (14, 15) and a recess (27, 38) in the carrier element, and having a connecting element head (27, 39) that is supported on the lining carrier (14, 15). The lining carrier (14, 15) has a shoulder (48, 49) in the region of die connecting element head (27, 39), the internal dimension (50, 51) of which shoulder is greater than the external dimension (30, 41) of the connecting element head (27, 38), such that at least part of the connecting element head (27, 38) is accommodated in said shoulder (48, 49).
Thu, 07 Jul 2016 08:00:00 EDTA 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.
