Abstract: A clutch device includes a clutch center, and a pressure plate movable toward or away from the clutch center, rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The clutch center includes center-side fitting teeth holding the input-side rotating plates and the output-side rotating plates, projecting radially outward from an outer peripheral surface of an outer peripheral wall, and arranged in circumferential directions, and an oil channel in an end portion of at least one of the center-side fitting teeth in a second direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to outside of the clutch center.

Abstract: A clutch device includes a pressure plate movable toward and away from a clutch center to press input-side rotating plates and output-side rotating plates. An oil flow hole is located in a spline groove to penetrate an outer peripheral wall of the clutch center, to enable clutch oil having flowed out of an output shaft to be discharged to outside of the clutch center, and located between an end of a center-side slipper cam surface in a second circumferential direction and a center-side cam hole located ahead, in the first circumferential direction, of the end in the second circumferential direction, in the circumferential directions. A through hole is located ahead, in the first circumferential direction, of the end of the center-side slipper cam surface in the first circumferential to guide clutch oil flowing outside the clutch center to the inside of the clutch center.

Abstract: A multi-plate clutch includes an outer plate mounted on a radial outside and axially displaceable, an inner plate mounted on a radial inside and axially displaceable, and a plurality of leaf springs. The plurality of leaf springs is distributed around an outer circumference of the outer plate to mount the outer plate in a torque-transmitting manner on a rotor pot, or the plurality of leaf springs is distributed in an inner circumference of the inner plate to mount the inner plate in a torque-transmitting manner on a driving ring. In an example embodiment, the multi-plate clutch is a dry multi-plate clutch for a hybrid drivetrain. In an example embodiment, the multi-plate clutch includes a plurality of outer plates and a plurality of inner plates.

Abstract: A hub unit for a clutch of a vehicle with a handlebar has both a servo function when closing and a slipper function via the sliding motion of at least one pin along respective inclined and facing tracks. The hub unit includes a hub connected to an output shaft of a vehicle engine and having an axis of rotation, a plurality of guides rigidly connected to the hub, an axial stop rigidly connected to the hub, a disc pressure flange movable in a direction parallel to the guides, and at least one spring. The hub defines at least a first track and a second track facing in an axial direction and arranged in a direction not parallel to the axis of rotation. The disc pressure flange includes at least one pin projecting in a substantially radial direction and arranged in contact with the first track and the second track.

Abstract: A clutch includes a drive disc, a driven disc, and a friction plate unit capable of engaging or disengaging the drive disc with or from the driven disc, the friction plate unit including a first friction plate assembly and a second friction plate assembly, the clutch further including a pressing unit configured to engage or disengage the drive disc with or from the driven disc selectively by the first friction plate assembly alone or by a combination of the first friction plate assembly and the second friction plate assembly. Such an arrangement enables the clutch to select an appropriate number of friction plates as required for engagement, solving the problem that in existing multi-plate clutches, it is impossible to select an appropriate number of friction plates to participate in work to make the clutches obtain optimal performance according to different working conditions of the automobile.

Abstract: A method for controlling a positive gearshift unit includes, in an engagement procedure, a coupling element, which is connected to a first coupling half and which has a beveled coupling toothing, is brought into engagement with a blocking element, which has a blocking toothing and which is connected to a second coupling half, and is brought into engagement with a catch element, which is connected to the second coupling half, which has a beveled catch toothing, and which is able to move circumferentially with respect to the blocking element. In the engagement procedure, a touch-point is set which comes after a crossing of a synchronous rotational speed in a rotational speed difference profile.

Abstract: Provided is a clutch device configured so that different desired torque values can be set without influence between assist torque and slipper torque. A clutch device 100 includes a center clutch 105 holding clutch plates 104 arranged facing friction plates 103 to be rotatably driven by a drive shaft, and a pressure clutch 111. The center clutch 105 includes center-side assist cam surfaces 106a and center-side slipper cam surfaces 106b. The pressure clutch 111 includes pressure-side assist cam surfaces 112a and pressure-side slipper cam surfaces 112b. A contact surface between the center-side assist cam surface 106a and the pressure-side assist cam surface 112a and a contact surface between the center-side slipper cam surface 106b and the pressure-side slipper cam surface 112b are formed at different positions in a radial direction.

Abstract: A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission includes a lamina, an axially movable contact plate, and a plurality of friction disks. The lamina has a first friction surface facing in a first axial direction, and a second friction surface facing in a second axial direction, opposite the first axial direction. The contact plate has a plurality of holders arranged to hold the lamina. Each of the holders forms a positive connection with the lamina in the circumferential direction, and each of the first friction surface and the second friction surface is frictionally connectible to a friction disk to transmit torque. A first friction disk is arranged to be positioned between a counter plate and the lamina, and a second friction disk is positioned between the lamina and the contact plate.
