  • Publication number: 20190269566
    Abstract: A moving device adapted to be actuated by a prime mover is disclosed. The moving device allows a caregiver to ride thereon. The moving device comprises a vehicle body and a plurality of rotors. The vehicle body includes a first frame portion and a second frame portion. The first frame portion allows the caregiver to ride thereon and the second frame portion allows a care receiver to ride thereon. The plurality of rotors are provided on the first frame portion and are rotatable in accordance with movement of the vehicle body. A wheel base defined by the plurality of rotors is constant. The second frame portion is provided on the first frame portion so as to be movable in accordance with a motion of the caregiver riding on and getting off the first frame portion.

  • Publication number: 20190185003
    Abstract: A power transmission apparatus transmits torque from a rotating electric machine and includes a first path, a second path, a clutch, and a fluid coupling. The second path is provided parallel to the first path. The clutch is provided on the first path. The clutch can assume an engaged state that transmits torque and a disengaged state that stops transmission of the torque. The fluid coupling is provided on the second path. The fluid coupling includes an input member into which the torque from the rotating electric machine is input, and an output member that outputs the torque input from the input member via a fluid to a drive wheel. The fluid coupling is configured such that a rotation speed of the input member is lower than a rotation speed of the output member when transmitting the torque from the drive wheel to the rotating electric machine side.

  • Patent number: 10215147
    Abstract: A power transmission apparatus, which is disposed on a power transmission path from an output shaft of an internal combustion engine to a transmission in a vehicle, is provided with a rotating electrical machine including a rotor and a stator. The rotor is coupled to a synchronous rotating member that rotates synchronously with the output shaft of the internal combustion engine, and takes a central axis of the output shaft of the internal combustion engine as a rotating shaft. The stator is fixed to a fixing member on a non-rotating side with respect to the synchronous rotating member, and faces the rotor with a first gap therebetween.

  • Publication number: 20190038486
    Abstract: A moving apparatus is rideable by a caregiver and operable by a motor. The moving apparatus includes a main body and a first rotating body mounted on the main body so as to be rotatable around a first rotation axis. The moving apparatus also includes a second rotating body mounted on the main body so as to be rotatable around a second rotation axis. The second rotation axis is disposed spaced apart from the first rotation axis. The first rotating body and the second rotating body contact the ground. The main body is configured such that a wheelbase defined by the first rotation axis and the second rotation axis is changeable.

  • Publication number: 20180304733
    Abstract: A power transmission apparatus for vehicle, incorporated in a vehicle equipped with a transmission, includes a forward-reverse switching mechanism with start function produced by adding a function of a vehicle start clutch to the forward-reverse switching mechanism. Additionally, a power transmission system for vehicle includes an internal combustion engine that is a power source for vehicle driving, the transmission, a torsional vibration damper that transmits torque of the internal combustion engine to the transmission, and the forward-reverse switching mechanism with start function of the power transmission apparatus for vehicle. The forward-reverse switching mechanism with start function is disposed between the transmission, and the internal combustion engine and the torsional vibration damper.
