A pressure plate arrangement for a friction clutch includes a housing rotatably fixed to an abutment arrangement for joint rotation about an axis of rotation and a plate arrangement with at least one intermediate plate and a pressure plate. At least one of the intermediate and pressure plates is mounted in the housing and axially movable relative thereto and rotateable about the axis of rotation. An energy storage device coupled to the housing generates an elastic restoring force on the plate arrangement. A releasing spring arrangement located between the housing and plate arrangement is tensioned to generate an elastic restoring force on the pressure plate in a second direction opposite to the first direction. A clutch disk arrangement is clamped between the abutment arrangement and the at least one intermediate plate, or between any two plates of the plate arrangement.

Pressure plate assembly, clutch disk arrangement, and friction clutch, especially a multi-disk clutch

A dual clutch assembly includes a torsional vibration damper and a dual clutch. The vibration damper has a primary side which can be coupled to a driving member for joint rotation about an axis, a secondary side which is rotatable about the axis, and a damper element arrangement between the primary side and the secondary side. The dual clutch includes an input area and two output areas, the input area supporting the secondary side of the torsional vibration damper in at least one of an axial and radial direction with respect to the primary side, each output area being coupleable with a respective driven member so as to be fixed against rotation with respect to the driven member. A bearing arrangement supports the input area in at least one of an axial and a radial direction with respect to a stationary subassembly.

Dual-clutch assembly

A multiple clutch system, particularly a double clutch system, includes a housing arrangement connectable to a drive element and rotatable therewith about an axis of rotation. The clutch system include a first coupling area and a second coupling area. The first coupling area includes a first pressure plate for pressing a friction area of a first clutch disc against an abutment area, the first pressure plate being rotatable with the housing arrangement, and first actuator device for activating the first coupling area to execute controlling operations. The second coupling area includes a second pressing plate for pressing a friction area of a second clutch disc against an abutment area, the second pressure plate being rotatable with the housing arrangement, and a second actuator device for activating the second coupling area to execute controlling operations. The first actuator device and/or the second actuating device is designed for generating an actuating force that acts upon the respectively assigned coupling area in the direction of engagement.

Multiple clutch system, particularly a double clutch system

A pressure plate assembly for a friction clutch includes a housing connectable with an abutment arrangement for rotation therewith about an axis of rotation. The housing has an outer axial side and an inner axial side. A pressure plate is mounted in the housing so that it faces the inner axial side. The pressure plate is rotatable with the housing about the axis of rotation. The pressure plate includes actuating sections which extend past a radially outer edge of the housing. An energy storage element is mounted on the outer side of the housing such that the energy storage device exerts a force on the actuating sections for urging the pressure plate away from the inner axial side. An assembly pretensioning arrangement is operative for holding the energy storage element in a pretensioned assembly position in which the energy storage device does not exert a force on the housing.

Pressure plate assembly for a friction clutch

A dual clutch includes a first clutch area with a housing arrangement connected to an abutment plate; a first pressure plate arrangement; and a force-exerting arrangement, which is supported against the housing arrangement and the pressure plate arrangement, and which can press the pressure plate arrangement toward the abutment plate. A second clutch area includes second pressure plate arrangement and a force-transmitting arrangement, which extends axially across the abutment plate and can exert force on the second pressure plate arrangement. The housing arrangement and the abutment plate are connected to each other by the production of a press fit, and a first force-transmitting element and a second force-transmitting element of the force-transmitting arrangement are also connected to each other by the production of a press fit.

Dual clutch

A motor vehicle drive train with a clutch device installed between a drive unit and a transmission having at least one transmission input shaft to transmit torque between the drive unit and the transmission. The clutch device comprises at least one clutch arrangement assigned to a respective transmission input shaft, where an input side of the clutch device is connected directly or indirectly by way of a torque-transmitting arrangement to a connecting end of a power takeoff shaft of the drive unit. The torque-transmitting arrangement has a radially outer connecting area for connection to the clutch device and a radially inner connecting area for the direct or indirect connection to the connecting end by the mediation of at least one positive connecting element, which connects the radially inner connecting area in a positive manner to the connecting end or to a component or assembly attached nonrotatably to the connecting end, and which secures the radially inner connecting area on the connecting end or on the component or assembly in the axial direction. The positive connecting element is located in a central radial area relative to an axis of rotation (A) of the clutch device, which area is essentially the same as or smaller than the radial area occupied by the minimum of one transmission input shaft.

Clutch device connected centrally on the input side to a rotating shaft or rotating component in a motor vehicle drive train

An actuating device for a friction clutch device installed in the drive train of a motor vehicle introduces actuating forces, especially clutch-engaging or clutch-releasing forces, to the friction clutch device to actuate at least one friction clutch of the friction clutch device in the engaging or releasing direction. At least one actuating element assigned to a friction clutch can be shifted axially relative to at least one support element, which is essentially fixed in the axial direction, to exert the actuating forces. The actuating element belongs to an actuator assigned to the clutch or can be shifted axially relative to the support element by the intermediate action of an actuator assigned to the clutch. The actuating element and the support element engage with each other in such a way that a rotational movement of the actuating element relative to the nonrotatably supported support element, this movement being imparted by the intermediate action of the actuator, is converted to an axial translational movement of the actuating element relative to the axially supported support element.
