Abstract: A clutch apparatus is provided which includes a center clutch and a pressure clutch that can hold a clutch plate without falling off of the clutch plate and also prevent a reduction in strength. A clutch apparatus 100 includes a center clutch 105 and a pressure clutch 112, which hold clutch plates 104 placed facing friction plates 103 that are rotationally driven by a driving shaft. The center clutch 105 includes a center-side mating portion 108 mating with internal teeth of the clutch plate 104. In addition, the center-side mating portion 108 includes a protruding tooth 110. The pressure clutch 112 includes a pressure-side mating portion 116 mating with internal teeth of the clutch plate 104. In addition, the pressure-side mating portion 116 includes a run-off 117. The protruding tooth 110 extends over the run-off 117 of the pressure-side mating portion 116, as one of spline teeth forming the center-side mating portion 108.

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: 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 clutch device includes a clutch center including center-side fitting teeth, and a pressure plate including pressure-side fitting teeth. When a center-side assist cam surface and a pressure-side assist cam surface contact each other, an end of each of the pressure-side fitting teeth in a first direction is located ahead, in the first direction, of an end of a corresponding one of the center-side fitting teeth in a second direction, and at least portions of some of the pressure-side fitting teeth overlap with the center-side fitting teeth when seen in radial directions of the output shaft, and at least portions of others of the pressure-side fitting teeth do not overlap with the center-side fitting teeth when seen in radial directions of the output shaft.

Abstract: A clutch device includes a pressure plate movable toward or away from a 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 an oil passage, at least a portion of which is located in an inner peripheral surface of an outer peripheral wall to guide clutch oil to a center-side fitting portion. The pressure plate includes a pressure-side recess on an outer peripheral surface of a pressure-side fitting portion, recessed radially inward from the outer peripheral surface over the entire outer peripheral surface in movement directions, and continuous with the pressure-side cam hole when seen in movement directions. The pressure-side recess communicates with the oil passage.

Abstract: A power transmitting apparatus inputs or cuts off rotational power of an input member (1) to an output member (3) by press-contacting a plurality of driving-side clutch discs (6) and a plurality of driven-side clutch discs (7) with each other or releases them. A clutch housing (2) includes the driving-side clutch discs (6). A clutch member is (4) connected to the output member (3). A pressure member (5) press-contacts the discs (6) and discs (7) with each other or releases the press-contacting force between them. Application of a resisting force, for resisting relative rotation between the clutch member (4) and the pressure member (5), can be attained. A magnitude of the resisting force is set larger than a sticking torque between the discs (6) and discs (7).
