Abstract: A driving apparatus includes a rotary electric machine configured to output rotation in a first direction and rotation in a second direction, a fluid pump and an actuator that are configured to operate with the output of the rotary electric machine as power, and a one-way clutch provided between the rotary electric machine and the actuator. The fluid pump is configured to intake and discharge a fluid when at least the rotation in the first direction is input. The one-way clutch is configured to block the rotation in the first direction and transmit the rotation in the second direction. The actuator includes a shift drum configured to rotate in one direction in response to the rotation in the second direction transmitted via the one-way clutch, and a shift fork engaged with the shift drum. The shift fork has a plurality of operating states including at least a first state and a second state, and alternately transitions between the first state and the second state in response to the rotation of the shift drum in the one direction.

Abstract: A vehicle driveline component with a ball-ramp mechanism that includes a first ball-ramp ring, a second ball-ramp ring and a plurality of balls. Each of the first and second ball-ramp rings have a plurality of ball supports that define ball tracks that receive the balls. Each of the ball supports has a first radial width at a first location and a second radial width at a second location. The first and second widths are different to minimize the amount of material that forms the first and second ball-ramp rings.

Abstract: A normal-time drive cam groove extends from a drive cam specific point, which is defined as a specific point of the drive cam, toward one side in a circumferential direction of the drive cam. A groove bottom at the normal-time drive cam groove is sloped relative to one end surface of the drive cam such that a depth of the groove bottom continuously decreases from the drive cam specific point toward the one side in the circumferential direction of the drive cam. An emergency-time drive cam groove extends from the drive cam specific point toward another side in the circumferential direction of the drive cam.

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: At a drive cam slope groove, a groove bottom is sloped relative to one end surface of a drive cam such that a depth of the groove bottom continuously decreases from one side toward other side in a circumferential direction. At a drive cam planar groove, the groove bottom is parallel to the one end surface of the drive cam. A drive cam connection groove has: one end connected to an end of the drive cam slope groove located on the other side in the circumferential direction of the drive cam; and the other end connected to an end of the drive cam planar groove located on the one side in the circumferential direction. A slope angle of the groove bottom relative to the one end surface of the drive cam continuously changes from the one end to the other end of the drive cam connection groove.

Abstract: A state changing unit is provided radially outward of a translation portion and movable in an axial direction relative to the translation portion. The state changing unit is in contact with or separated from the clutch. The state changing unit receives a force in the axial direction from the translation portion such that the state changing unit is pressed against the clutch. The state changing unit is capable of changing a state of the clutch to an engaged state or a disengaged state according to a position of the translation portion in the axial direction relative to the housing. A movement restriction portion is provided on the translation portion and located between the state changing unit and the clutch. The movement restriction portion contacts the state changing unit and restricts movement of the state changing unit relative to the translation portion toward the clutch.

Abstract: The present invention provides a rotary shaft assembly applied to a novel clutch system that ensures a 100% torque transmission rate between an engine and a transmission in a vehicle system and can be commonly applied to conventional manual transmission vehicles and automatic vehicles. The rotary shaft assembly converts linear motion of one member to rotary motion of another member, using a combination of a protrusion and an inclined guide slot.

Abstract: A prime mover includes a stator fixed to a housing and a rotor relatively rotatable relative to the stator. The prime mover outputs torque from the rotor by being supplied with electric power. A speed reducer reduces the torque of the prime mover and outputs the reduced torque. One bearing portion rotatably supports the rotor. The speed reducer includes an input portion that is coaxial and integrally rotatable with the rotor and receives the torque from the rotor.
