The present invention relates to a clutch (100) comprising: a fixed hub (101, 1101) comprising a central coupling hole (301) configured for coupling with a rotating shaft (1200); a movable hub (102, 1102) configured for being mounted along an axial direction onto the fixed hub (101, 1101); a plurality of discs (103) interposed between the fixed hub (101, 1101) and the movable hub (102, 1102). The fixed hub (101, 101) and the movable hub (102, 1102) are shaped so as to rotate jointly with each other and so as to axially slide with each other, getting farther or closer to each other so that the fixed hub (101, 1101) and the movable hub (102, 1102) exert a variable axial load onto the plurality of discs (103), thereby transmitting a torque. The movable hub (102, 1102) comprises a central access hole (302) that is configured for allowing access to said central coupling hole (301) passing internally through the plurality of discs (103) interposed, so as to operate locking means (1201) for the coupling with the rotating shaft (1200). The present invention also relates to a method for mounting a clutch.

A clutch device includes a clutch plate and a clutch outer. The clutch plate includes a plurality of teeth circumferentially disposed apart from each other. The clutch outer includes a bottom portion, a plurality of cover portions, and a plurality of openings. The bottom portion has a disc shape and is greater in diameter than the clutch plate. The cover portions axially extend from an outer peripheral edge of the bottom portion so as to cover the teeth. The cover portions are circumferentially disposed apart from each other. Each opening is disposed between each adjacent pair of the cover portions. Each opening is radially opened.

The disclosure relates to a disk (38) for a disk clutch (26) comprising an annular base element (76) which has a toothing (78) with multiple teeth (80) for achieving a rotary driving engagement with a disk carrier (34), wherein the base element (76) has at least one hardened region (96) in which the base element (76) is designed as harder than in the tooth flank regions (98, 100) of the teeth (80). In addition, the disclosure relates to a disk clutch (26) with such a disk (38), a double clutch device (2) with such a disk clutch (26), and a method for producing such a disk (38).

The invention relates to a friction plate (10) having a basic body (5 or 9), which is formed from at least one strip (11), deviating from the circular-ring shape.

A hub assembly for a hybrid module having a first and a second connection partner arranged coaxially with one another, the first connection partner has a first bearing portion and the second connection partner has a second bearing portion, and a plurality of connecting elements. The first and the second bearing portion have receiving openings for receiving the connecting elements. The first and the second connection partner are prepositioned with respect to one another via a form-fitting connection such that the receiving openings in the first and the second bearing portion are each oriented in pairs in a positionally correct manner with respect to one another in the circumferential direction about the main axis H.

A clutch carrier includes a first component and a second component. The first component has an undulating ring, a cylindrical ring, and a connector portion. The undulating ring has an inner surface, and an outer surface for mating engagement with a clutch plate spline. The connector portion is between the undulating ring and the cylindrical ring. A plurality of apertures are defined at least partially in the connector portion. The second component has a first radial wall, a plurality of segments, and a plurality of formable tabs. The plurality of segments extend axially from the first radial wall and contact at least a portion of the inner surface to radially position the second component within the first component. The plurality of formable tabs extend from the first radial wall through the plurality of apertures.

A multiple clutch for a drivetrain of a motor vehicle includes an a axis of rotation, a first clutch, a second clutch, and an encoder part. The first clutch has a first clutch first component and a first clutch second component selectively rotationally connectable to the first clutch first component. The second clutch has a second clutch first component and a second clutch second component selectively rotationally connectable to the second clutch first component. The encoder part has a rotational speed or rotational position detection geometry, is arranged to be operatively connected to a sensor, and is used as a connecting element which rotationally conjointly connects the first clutch first component to the second clutch first component.

An input drum of an automotive transmission for motor vehicles is formed from a plurality of components assembled together. The input drum has a hub having outwardly extending tabs, and a clutch cylinder having internal grooves for receiving the tabs when the hub is assembled to the clutch cylinder. The hub and the clutch cylinder are arranged such that openings in the hub and openings in an inwardly extending circumferential flange of the clutch cylinder are in axial alignment when the tabs of the hub are received in the internal grooves of the clutch cylinder. The hub and clutch cylinder are assembled together by connecting elements extending through the aligned openings in the hub and clutch cylinder. An input shaft is permanently or removably attached to the hub.

A clutch assembly comprises an input shaft and an output shaft, co-axially arranged relative to the input shaft. The clutch assembly further comprises an input clutch drum, fixed to the input shaft, and an output clutch drum, translatable relative to the output shaft. The clutch assembly further comprises a clutch pack and a clutch piston that is translatable relative to the output shaft between, inclusively, a frictionally disengaged clutch-pack position and a frictionally engaged clutch-pack position. The clutch assembly additionally comprises a clutch-pack engagement spring. The output clutch drum is translatable between, inclusively, a fully disengaged position and, inclusively, a positively engaged position. When the clutch piston is in the frictionally disengaged clutch-pack position, the internal splines of the output clutch drum are not in mesh with the external splines of the input clutch drum.

A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.
