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 clutch operator arrangement for introducing an actuating force into a friction clutch includes a ball screw arrangement.

Clutch operator arrangement

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.

Leaf spring arrangement, especially for attaching the pressure plate of a pressure plate assembly to a housing

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 ball screw includes a spindle element which has a first groove arrangement on an outer circumferential surface, a nut element which surrounds the spindle element and has a second groove arrangement on an inner circumferential surface, and a plurality of balls, at least some of which engage into the first groove arrangement and the second groove arrangement. The nut element is rotatable about an axis of rotation with respect to the spindle element, and, during the rotation of the nut element about the axis of rotation with respect to the spindle element, the balls which engage into the first groove arrangement and the second groove arrangement roll in the first and the second groove arrangement, while at the same time rotate about respective ball axes of rotation. In this case, there is provision, with respect to the ball axis of rotation, for an effective ball rolling radius with which the balls roll in the first groove arrangement to be smaller than the effective ball rolling radius with which the balls roll in the second groove arrangement.

Ball screw

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 first clutch area produces a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area produces a second torque-transmitting connection between the drive element and a second driven element. A common engaging/disengaging mechanism actuates the first clutch area and the second clutch area to produce and to nullify the first and second torque-transmitting connections.
