  • Patent number: 11320046
    Abstract: A power transmission apparatus includes a shift drum, a clutch, a clutch lifter, and a transmission body. The shift drum makes a dowel be extracted/inserted between a shifter and a shift gear. The clutch has first friction plates and second friction plates. The first friction plates rotate around a main shaft by receiving power from a crankshaft. The second friction plates are disposed alternately with the first friction plates and are relatively non-rotatably supported by the main shaft. The clutch lifter is displaced between a connection position at which power is transmitted by the clutch and a disconnection position at which the transmission of the power is disconnected. The transmission body transmits a driving force to the shift drum while the clutch lifter moves from the connection position to the disconnection position, in accordance with rotation of a shift spindle that rotates in accordance with a driving force.

  • Patent number: 11279338
    Abstract: A control device for a hybrid vehicle includes an engine operating point control unit that shifts an engine operating point to an engine operating point on an optimal fuel-efficiency operating line outside a predetermined noise generation region in which combustion sounds of an engine become noise when the engine operating point is in the noise generation region. Accordingly, when the engine operating point is in the noise generation region, the engine operating point control unit shifts the engine operating point to an engine operating point on the optimal fuel-efficiency operating line outside the noise generation region. As a result, since the engine operating point is not separated from the optimal fuel-efficiency operating line even when the engine operating point departs from the noise generation region, it is possible to curb a decrease in fuel efficiency.

  • Patent number: 11268580
    Abstract: The invention relates to an electrically driven clutch actuators (1) for actuating the clutch of a transmission of a vehicle. An actuator comprises a spindle nut (11) on a spindle (9) and a pressure piece (13) displaceable relative to the spindle nut (11) and coupled to the spindle nut by a biasing spring (15). By rotation of the threaded spindle under a driving force of an electric motor (5), the spindle nut (11) compresses the biasing spring (15) and displaces the pressure piece (13) to disengage the clutch. A latching mechanism (16) is configured to limit displacement of the spindle nut away from the pressure piece under the force of the expanding biasing spring when the driving force is reduced below a predetermined level. Further, a control unit is described that reduces the driving force in response to a trigger condition to reduce power consumption in the clutch disengaged state.
