Abstract
To perform simple and precise shift changes without using a change pedal and a change lever. In conjunction with the engagement and disengagement of a transmission clutch, a shift spindle rotates a shift drum to establish predetermined gear levels, and is rotatably driven via moderator gears by a motor. By operating a shift up switch or shift down switch not illustrated, the motor rotates the shift spindle in a prescribed direction, the transmission clutch and shift drum.
Claims6
A power transmission device for a vehicle, equipped with a transmission provided between an engine and drive wheels and a transmission clutch provided between the engine and the transmission, comprising:
- an electric actuator for controlling engagement of said transmission clutch based on command signals from manually actuated operating members, wherein said electric actuator is a motor capable of rotating in a forward and reverse direction, said motor being controlled such than an engagement speed of said transmission clutch is slower than a disengagement speed of said transmission clutch.
A power transmission device for a vehicle comprising:
- a transmission operatively connected to a power source;
- drive wheels operatively connected to said transmission;
- a transmission clutch provided between the power source and the transmission;
- and
- an electric actuator for controlling engagement of said transmission clutch based on command signals from manually actuated operating members, wherein said electric actuator is a motor capable of rotating in a forward and reverse direction, said motor being controlled such that an engagement speed of said transmission clutch is slower than a disengagement speed of said transmission clutch.
