Abstract: A clutch device includes a clutch center and a pressure plate operable to move toward or away from the clutch center and rotatable relative to the clutch center. The pressure plate includes a pressure-side cam portion. The clutch center includes a center-side cam portion. The pressure plate includes a boss extending in movement directions. The clutch center includes a through hole in which a boss is insertable. The through hole extends along circumferential directions and allows movement of the boss along the circumferential directions and the movement directions. While a surface of the pressure-side cam portion and a surface of the center-side cam portion are in contact with each other, a distal end of the boss projects outward from the through hole.

Abstract: Pressure-side cam portions of a pressure plate each include a pressure-side assist cam portion including a pressure-side assist cam surface, a pressure-side body located between the pressure-side assist cam portion and a pressure-side slipper cam portion, and a first stepped portion between a main outer circumferential surface of the pressure-side body and a sub outer circumferential surface of the pressure-side assist cam portion. The sub outer circumferential surface is located radially inward of the main outer circumferential surface. The sub outer circumferential surface is inclined radially inward in a second direction. Among portions of the main outer circumferential surface, at least a stepped portion-side outer circumferential surface adjacent to the first stepped portion is inclined radially outward in the second direction.

Abstract: A separating clutch for a powertrain includes a rotational axis, a friction pack for transmitting a torque in an engaged state, a damper device having a torsional vibration damper or a centrifugal pendulum, and an actuation device for selectively releasing the engaged state. The actuation device is arranged in an axial overlap with the damper device. The friction pack may include a friction disk, a pressure plate, a counter-plate, a pressure pot, and a disk spring supported between the counter-plate and the pressure pot. The friction disk may have a friction surface and the pressure pot may extend through the counter-plate to contact the pressure plate, radially outside of the friction surface, and the actuation device, radially inside of the friction surface. The actuation device may include a pressure chamber with a pressure piston, and the pressure piston may be axially movable and arranged radially within the friction pack.

Abstract: A metering device for controlling an oil delivery rate for a wet-running clutch. The wet-running clutch has at least one pair of interacting friction surfaces and an actuation unit for actuating the wet-running clutch. The actuation unit has an axially supported support disk and an axially displaceable thrust disk, wherein the thrust disk and the support disk are rotatable relative to one another. The metering device has a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner.

Abstract: An indexing assembly for a snowmobile drive clutch assembly includes an adapter collar having a first portion which is hexagonal in cross section for mounting in the index socket of the drive clutch housing which normally receives a conventional indexing bolt therein. The adapter collar defines a first indexing surface which mates with a corresponding second indexing surface of the indexing head of an auxiliary bolt which replaces the conventional indexing bolt to define an eccentric cam surface which defines the ramp angle of a flyweight ramp member of the drive clutch that can be adjusted through a greater number of mating positions than the conventional indexing bolt. A difference in ramp angle between sequential mating positions of the auxiliary bolt can thus be made smaller than the difference in ramp angle between sequential mating positions of the conventional indexing bolt.

Abstract: A backing plate assembly includes a front cover and a rear cover. The front cover defines an inner surface and a front plane, and the rear cover terminates at a lip. A backing plate forms a body having an outer surface that terminates at a base portion. When the outer surface is coupled to the inner surface, the backing plate is rotationally but not axially coupled to the front cover. The lip contacts the base portion to define a maximum axial distance between the backing plate and the front plane.

Abstract: A friction element assembly for a transmission of a motor vehicle includes a set of plates and friction members. A piston assembly is configured to apply a force to the set of plates and friction members. The friction element assembly also includes a housing with a mounting groove; a pressure plate having first and second edges; and a snap ring positioned in the mounting groove. The snap ring is positioned such that first edge of the pressure plate contacts the snap ring and the second edge of the pressure plate extends across a portion of the snap ring. The snap ring is L-shaped and includes a leg portion that contacts the second edge of the pressure plate when the piston assembly applies a force to the set of plates and friction members.

Abstract: A clutch assembly for transmitting power from an output shaft of an engine to an input shaft of a gearbox includes annular friction surfaces on at least one of the flywheel and the pressure plate. The annular friction surface has a plurality of grooves that extend across the annular friction surface away from an inner rim of the friction surface toward an outer rim of the friction surface to prevent a reduction in friction caused by outgassing or abraded particles trapped between engaging friction surfaces.
