    摘要: A torque limiter includes a first side plate, a second side plate, a friction disc, a pressure plate, and a biasing member. The first side plate includes an attachment surface. The attachment surface faces in an axial direction so as to be attached to a flywheel. The second side plate has a smaller outer diameter than the outer diameter of the first side plate. The second side plate is disposed so as to not overlap the attachment surface as seen in an axial direction. The second side plate is attached to the first side plate.

    摘要: A damper device includes a damper unit and a torque limiter unit. The damper unit includes first and second plates each including a plurality of window portions, a hub flange including a plurality of window holes, and a stopper mechanism. The first plate includes an engaging portion and a fixing portion fixed to the second plate. The engaging portion and the fixing portion are disposed radially outside the plurality of window portions. The hub flange includes a protrusion disposed circumferentially between and radially outside adjacent two of the plurality of window holes. The stopper mechanism is configured to be actuated by contact of the protrusion with the engaging portion. A fixation member, by which the first plate and the torque limiter unit are fixed, is disposed circumferentially between adjacent two of the plurality of window portions as seen in a direction along a rotational axis.

    摘要: A flow channel structure forms a first flow channel which makes a first fluid chamber and a second fluid chamber communicate with each other therethrough. The flow channel structure includes first to third plates. The first plate includes a first through hole penetrating the first plate in a thickness direction to open to the first fluid chamber. The second plate includes a second through hole penetrating the second plate in the thickness direction to open to the second fluid chamber. The third plate includes a first connecting through hole penetrating the third plate in the thickness direction. The first connecting through hole is larger in flow channel area than each of the first and second through holes. The first and second through holes are disposed in different positions from each other as seen in the thickness direction. The first connecting through hole communicates with the first and second through holes.

    摘要: A drive unit includes an electric motor, a torque converter, a reducer, a first shaft, a second shaft, and a clutch. The torque converter amplifies a torque generated by the electric motor when the torque is directed in a first rotational direction. The reducer is configured to output the torque by reducing a speed of rotation of the electric motor. The first shaft transmits the torque from the electric motor to the torque converter. The second shaft transmits the torque from the torque converter to the reducer. The clutch is disposed in the interior of the reducer. The clutch allows or blocks transmission of the torque between the first shaft and the second shaft.

    摘要: A damper device includes a first rotor, a second rotor, and an elastic member. The first rotor includes a contact surface. The contact surface faces a circumferential direction and extends in a radial direction. The second rotor is disposed to be rotatable relative to the first rotor. The second rotor includes a stopper surface extending in the radial direction. The stopper surface is opposed to the contact surface at an interval in the circumferential direction. The elastic member elastically couples the first rotor and the second rotor.

    摘要: A drive unit includes an electric motor, first and second torque transmission paths, a torque converter, first and second gear trains, and a first switch mechanism. The first and second torque transmission paths are provided parallel to each other. The torque converter is disposed in the first torque transmission path. The torque converter amplifies a torque outputted from the motor when the torque is directed in a first rotational direction. The first gear train is disposed in the first torque transmission path. The first gear train is disposed downstream with respect to the torque converter. The second gear train is disposed in the second torque transmission path. The first switch mechanism switches between the first torque transmission path and the second torque transmission path as a path for transmitting the torque outputted from the motor.

    摘要: A mobile object control device controls an electric motor assisting traveling of a mobile object. The mobile object control device includes a rolling resistance calculation section, a power loss calculation section, and an assist force calculation section. The rolling resistance calculation section calculates a rolling resistance based on a set weight set by a user. The power loss calculation section calculates a power loss caused until a power outputted from the electric motor is transmitted to a drive wheel. The assist force calculation section calculates an assist force of the electric motor based on an acceleration of the mobile object, the set weight, the rolling resistance calculated by the rolling resistance calculation section, the power loss calculated by the power loss calculation section, and an assist ratio.
