At least a portion of a second shaft is drivingly connected to the second clutch member.

A rotation transmission disc includes: an outer circumferential portion on which a load acts when rotation is transmitted; a center opening portion formed inside the outer circumferential portion; and a plurality of attachment holes for attachment of the rotation transmission disc 1 to a rotating element. A first crosspiece portions are formed in each of ranges of divided angles formed by two adjacent attachment holes with respect to a center of the rotation transmission disc. The first crosspiece portion extends from a load point, which is an intersection between a straight line extending in a radial direction to internally divide the divided angles at a predetermined angular ratio and a load radius position of the outer circumferential portion, to one of the attachment holes forming the divided angles. The second crosspiece portion extends from the load point to the other attachment hole of the attachment holes forming the divided angles.

A clutch and a compressor including the same, and may include a hub fastened to a rotary shaft of a compressor and rotatable with the rotary shaft in a state where its position has been fixed, a disk fastened to the hub and rotatable with the hub, a pulley rotated by receiving power from a driving source of the compressor, an elastic member fastening the hub and the disk, fastening the hub and the disk so that the disk approaches or is away from the pulley based on the hub, a field coil assembly magnetized when power is applied to contact or space the disk and the pulley, an attenuation member interposed between the elastic member and the disk, thereby reducing the noise and vibration due to the contact and spacing between the disk and the pulley by the elastic member and the attenuation member.

An improved clutch hub assembly is disclosed. The improved clutch hub assembly provides improved wear resistance at the interfaces between separator plates and a clutch hub while allowing an operator to have improved clutch lever control and modulation when manually engaging or disengaging the clutch system.

A clutch hub assembly includes a hollow shaft extending in the longitudinal direction having an internal surface, an external surface, a first end, and a second end. A plate is engaged to the external surface of the shaft, extending outwardly from the external surface of the shaft in the axial direction and having a top surface and a bottom surface. A collar is engaged to the plate having an internal surface and an external surface, wherein the top surface of the plate and the internal surface of the collar define a cavity. A plurality of teeth axially extending from the external surface collar, and a support member extends outwardly from the collar.

A clutch includes a hub and a flange located radially inside and outside, respectively, with respect to the clutch rotational axis and associated with hub and flange sides of the clutch. A spring elastically supports the hub and flange sides against each other in the circumferential direction in a torque-transmitting manner. A bearing radially supports the hub and flange sides against one another for rotation around the axis and includes an outer ring supporting the hub and an inner ring supported on a bearing pin associated with the flange side. A friction device connects the hub and flange sides in a friction-locked and torque-transmitting manner in the circumferential direction and includes a friction element and a friction surface which are pretensioned against one another in the axial direction. A tensioning device includes a tensioning element that applies force to, and axially pretensions, the friction device and bearing.

A clutch device includes a first rotor, a second rotor, and a clutch plate. The first rotor includes a first slide surface. The second rotor includes a second slide surface disposed axially apart from the first slide surface. The second rotor is axially movable relative to the first rotor. The clutch plate is disposed between the first slide surface and the second slide surface. The first rotor includes an opposite surface that is axially opposite to the first slide surface. The opposite surface includes a plurality of recesses, a ribbed portion, and a coupling portion. The recesses are circumferentially aligned. The ribbed portion radially extends between each adjacent pair of the recesses. The coupling portion is disposed radially outside the recesses and circumferentially extends such that each adjacent pair of ribs in the ribbed portion is coupled therethrough.

A clutch device includes a clutch housing including a cylindrical portion and a bottom, a multiple disc clutch, a receiving member and a pressing member that moves in an axial direction with respect to the clutch housing to press the multiple disc clutch from the bottom side toward the receiving member. The pressing member includes an annular portion disposed radially inward or outward of the bottom and a plurality of protruding portions protruding in a radial direction from the annular portion, the annular portion being provided integrally with the protruding portions. The bottom of the clutch housing has a plurality of cutouts that accommodate the protruding portions. The protruding portions move in the axial direction within the cutouts to press the multiple disc clutch.

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).

A damper device includes a first rotor, a second rotor, a plurality of elastic members and a stopper mechanism. The stopper mechanism includes a plurality of first cutouts, a plurality of second cutouts and a plurality of stop members. A pair of the first and second cutouts is provided on both circumferential sides of each of a plurality of accommodation portions of the second rotor so as to circumferentially extend therefrom. The stop members are fixed to the first rotor. Each stop member is circumferentially movable within the pair of the first and second cutouts. The second rotor includes a first protruding portion circumferentially protruding on one of a pair of pressing surfaces of each accommodation portion. Each of the first cutouts, which is a hole, extends at an end thereof located closer to each accommodation portion toward the first protruding portion.
