Abstract: A power transmission apparatus includes a clutch connected to an output shaft to rotate a wheel of a vehicle, and a clutch pressure plate movable between an operating position where driving and driven clutch plates are pressed against each other so as to enable transmission of a driving force of an engine to the wheel and a non-operating position where a pressing force exerted on the driving and driven clutch plates is released so as to cut off transmission of the driving force of the engine to the wheel. One of the driven clutch plates is attached to a second clutch, and another is attached to the clutch pressure plate. The clutch pressure plate includes an oil flow passage through which oil flows to the driven clutch plate attached to the clutch pressure plate.

Abstract: A motor performing power driving and regeneration has an inverter, a mechanical brake, a power storage device supplying energy to the motor, an accelerator operator controlling the motor to adjust a drive torque of a driving wheel, a mechanical brake operator controlling the mechanical brake to adjust a braking torque, a regenerative brake operator adjusting a braking torque of the driving wheel and recovering the energy into the power storage device, and a detector detecting a rotation speed of the motor. When the rotation speed of the motor is equal to or higher than a predetermined value, a predetermined braking torque, based on an operation amount of the regenerative brake operator, is generated by regenerative braking.

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: An aluminum component and a method for manufacturing the aluminum component has a forming step and a cutting step. Projections (f) extend in an axial direction and are continuously arranged in a circumferential direction. End portions of the projections (f) are cut along a processing line having a predetermined processing diameter (D) providing splines (S) of predetermined dimensions. Side surfaces (fa) are inclined to be tapered in a direction from a base end to a projecting end. A portion of each side surface (fa) adjacent to the projecting end is an inclined surface (fb) with an inclination angle less than an inclination angle of a portion of the side surface that is adjacent to the base end.

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 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: In a power transmission apparatus, a centrifugal clutch includes a holder, a press, a first spherical body that is partially protruded from a first opening and in contact with a rolling contact surface of the press so as to be rollable thereon, and a second spherical body that is partially protruded from a second opening and in contact with a rolling contact surface of the holder so as to be rollable thereon. A through hole has a tapered shape from the first opening to the second opening. Disconnection of the first spherical body is prevented by an outer peripheral edge of one of the first opening and the second opening that has a smaller diameter.

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: In a power transmission apparatus, an auxiliary clutch plate different in diameter from driving and driven clutch plates located in a clutch housing. When the driving and driven clutch plates are pressed against each other, the auxiliary clutch plate is pressed to enable transmission of a driving force of an engine to a driving wheel. When a pressing force exerted on the driving and driven clutch plates is released, a pressing force exerted on the auxiliary clutch plate is released to cut off transmission of the driving force of the engine to the driving wheel.
