A multiple disk clutch device for arrangement in a drivetrain of a motor vehicle between a drive unit and a transmission, includes at least an inner and an outer disk clutch arrangement that are radially staggered and associated with a transmission input shaft of the transmission. Each of the plural clutch disk arrangements includes a set of disks, the set of disks have an outer disk associated with an outer disk carrier and an inner disk associated with an inner disk carrier. The outer disks are operable to mutually engage the inner disks in a driving arrangement. Each of the plural disk sets includes at least one disk having a lining and at least one disk being unlined where one of the inner and outer disks of the inner and the outer disk clutch arrangements of the plural disk clutch arrangements is the lined disk.

Double or multiple disk coupling device and disk arrangement therefor

A rotary driving insertion connection, particularly for transmitting torque in a drivetrain of a motor vehicle between components or units of the drivetrain which are connected or are to be brought into a connection for transmitting torque, comprises a primary-side coupling area at a first component and a secondary-side coupling area at a second component. One of the coupling areas has a cutout which is defined by an inner circumference or at least an inner circumferential portion, and the other coupling area has at least one projecting portion having an outer circumference or at least an outer circumferential portion which is inserted or can be inserted into the cutout axially with reference to an axis of rotation in order to provide a positive rotary driving engagement between the inner circumference and the outer circumference. A plurality of coupling elements producing the positive rotary driving engagement is provided between the inner circumference and the outer circumference.

Rotary driving insertion connection, particularly for transmitting torque in a drivetrain of a motor vehicle

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 system includes a clutch device with at least one clutch arrangement for installation in a motor vehicle drive train between a drive unit and a transmission. The at least one clutch arrangement is actuated by a slave cylinder using a pressure medium which is supplied to the clutch device by a first pump. A further medium is also supplied to the clutch device by a second pump arrangement as an operating medium used during operation of the clutch device. The further medium is selectively supplied as a pressure medium to the slave cylinder.

Clutch system

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

Clutch operator arrangement

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

Torque transmission unit includes an input shaft and an output shaft with a torsion damping device functionally arranged between the input shaft and an output shaft. A shift clutch is also operatively arranged between the input shaft and the output shaft for selectively varying the torque transmitted from the input shaft to the output shaft. The torsion damping device has at least a primary mass and a secondary mass, the primary mass being effectively connected to the input shaft and the secondary mass being effectively connected to the output shaft. The torque transmission unit further comprises an electric machine with a stator and a rotor effectively connected to the input shaft. At least one of the shift clutch and the torsion damping device is arranged within an annular space delimited by the rotor and the stator of the electric machine.
