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.

Actuating device for a friction clutch device, possibly a dual or multiple friction clutch device

A dual clutch arrangement including two clutch areas, each with a pressure plate connected to a housing arrangement for rotation in common around an axis of rotation (A) and which can be shifted in the axial direction with respect to the housing; and a clutch disk, the friction surface areas of which can be clamped between the respective pressure plate and an opposing support arrangement. Each of the clutch disks is designed to be connected nonrotatably to a different power takeoff element. In addition a clutch cooling arrangement, through which a coolant can flow, is installed adjacent to the clutch areas.

Multi-disk clutch arrangement

A clutch disk arrangement for a multi-disk clutch includes a hub element connectable to a shaft for rotation with the shaft about an axis of rotation. A carrier arrangement has a first carrier element and a second carrier element. The first carrier element is connected to the hub so that the first carrier element rotates with the hub. The second carrier element is connected to the first carrier element such that it is foxed with respect to rotation and axially movable relative to the first carrier element. The clutch disk arrangement further comprises at least two friction lining units. On of the friction lining units is firmly connected to the first carrier element and a second one of the friction elements is firmly connected to the second carrier element. Accordingly, the friction lining units are fixed with respect to rotation and axially movable relative to the hub element via the carrier arrangement.

Clutch disk arrangement for a multi-disk clutch

A friction clutch comprising a flywheel having a rotational axis; a housing assembly which can be fixed to the flywheel for rotation in common about the rotational axis; a pressure plate mounted in the housing assembly so that it is free to move in the axial direction but is essentially unable to rotate relative to the housing; an energy storing device for loading the pressure plate toward the flywheel; a clutch disk assembly with an area located between the pressure plate and the flywheel, and an intermediate friction lining element assembly to transmit torque. The friction lining element assembly includes at least one friction lining element on the flywheel and/or at least one such element on the pressure plate.

Friction clutch

A leaf spring arrangement, especially for connecting a pressure plate to a housing, comprises a plurality of adjacent leaf spring elements, where each leaf spring element has a first attachment area for establishing the connection the pressure plate, a second attachment area for establishing the connection to the housing, and a connecting area extending between the first attachment area and the second attachment area. At least certain areas of at least two of the leaf spring elements are spaced apart between their first attachment area and their second attachment area.

A clutch disk has a hub area with a rotational axis, the hub area carrying a friction lining assembly radially outside of the hub area. A damper mass assembly can move circumferentially around the rotational axis relative to the hub area and the friction lining assembly against the action of an elastic support assembly.

Clutch disk

A clutch disk includes a hub area and a plurality of friction lining elements, which are supported on the hub area and arranged in sequence in the circumferential direction relative to a clutch disk rotational axis (A). These elements provide at least part of an associated friction surface area, where the friction lining elements are intended to make frictional contact with an associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one friction lining element is supported so that the pressure exerted by its friction surface area against an opposing friction surface can change in response to a change in the sliding frictional interaction between its friction surface area and an opposing friction surface area which is or can be associated with it.

A clutch disk including a hub area and a plurality of friction lining elements carried on the hub area, which are arranged in sequence around the circumference relative to the clutch disk rotational axis, and provide at least part of the friction surface area, where the friction lining elements are designed to make frictional contact with the associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one friction lining element is carried on the hub area with freedom to shift position essentially in the circumferential direction relative to the rotational axis.

A double clutch assembly comprising a first clutch area for the optional production of a torque-transmitting connection between a drive element and a first driven element, a second clutch area for the optional production of a torque-transmitting connection between the drive element and a second driven element, and a common engaging/disengaging mechanism, by means of which the first clutch area and the second clutch area can be actuated to produce or to nullify the torque-transmitting condition.

Double clutch assembly

A clutch disk includes a hub area and a plurality of friction lining elements arranged in sequence in the circumferential direction relative to a clutch disk rotational axis, each providing at least part of an associated friction surface area. The friction lining elements are intended to make frictional contact with the associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one of the friction lining elements is supported on the hub area in such a way that it can move in the radial direction.

A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.

Pressure plate assembly for a friction clutch

A clutch disk comprises a hub area designed for nonrotatable connection to a shaft and at least one friction lining element supported on a support area arranged radially outside the hub areas. A circumferential support surface for circumferential support of each friction lining element is provided on the support area at each circumferential end of each friction lining element.

A clutch disk is provided having a connecting arrangement, by means of which the friction linings can execute a radial movement with respect to the hub rotation axis and/or tilting movement with respect to a plane orthogonal to the hub rotation axis.
