摘要： A rotating electrical machine of a brushless wound field type disposed between a stationary case and rotating member that rotates inside the case includes a stator held by the case, including an AC coil that generates a rotating magnetic field with an alternating current, a field core held by the case, the field core including a field coil that generates a magnetic flux with a direct current, a rotor fixed in contact with an outer circumferential surface of the rotating member and held rotatably relative to the stator and field coil, a rotor side core portion that is a part of the rotating member. The magnetic flux of the field coil passes from the field core through the rotor via the second air gap, the stator and rotor via the first air gap, the rotor side core portion, and the field core via the third air gap.

摘要： A lock-up device includes a clutch portion, an intermediate member, a driven plate, a damper portion and a dynamic damper device. The clutch portion is a portion into which a torque is inputted from a front cover. The intermediate member is a member into which the torque is inputted from the clutch portion. The driven plate is rotatable relatively to the intermediate member and is coupled to a turbine hub. The damper portion elastically couples the intermediate member and the driven plate in a rotational direction. The dynamic damper device is mounted to an outer peripheral part of the driven plate and attenuates fluctuation in a rotational speed.

摘要： A power transmission device is disclosed. The power transmission device includes an input member, an output member, a dynamic vibration absorbing device, a rotation fluctuation detecting unit, and a control unit. The input member is rotatably disposed and configured to receive the torque inputted from a drive source. The output member is configured to output the torque, inputted to the input member, to a drive wheel. The dynamic vibration absorbing device is disposed in a power transmission path including the input member and the output member. The rotation fluctuation detecting unit is configured to detect information regarding a rotational fluctuation in at least one of the input member and the output member. The control unit is programmed to perform active control of the dynamic vibration absorbing device so as to reduce the rotational fluctuation based on the information regarding the rotational fluctuation detected by the rotational fluctuation detecting unit.

摘要： A clutch device is disclosed. The present device includes a driven plate having an annular shape and a clutch center. The driven plate includes a plurality of engaging recesses. The clutch center is rotatable about an rotational axis and makes the driven plate movable in an axial direction and non-rotatable relatively thereto when the driven plate is assembled thereto. Additionally, the clutch center includes a body having a cylindrical shape, one or more first teeth and one or more protruding teeth as a guide portion. The one or more first teeth are provided on the body and are configured to engage with the engaging recesses of the driven plate. The one or more protruding teeth function as a slide guide when the driven plate is slid onto the clutch center so as to be assembled thereto.

摘要： A lock-up device includes an input-side rotary member, an output-side rotary member, an outer peripheral side torsion spring, a restriction member and a float member. The restriction member is attached to the output-side rotary member. The restriction member includes a first restriction part. The first restriction part is disposed at an interval from the output-side rotary member in an axial direction. The float member is rotatable relatively to the input-side rotary member and the output-side rotary member. An inner peripheral end of the float member is disposed between the output-side rotary member and the first restriction part in the axial direction.
