摘要： A viscous damper for driving accessories by a crankshaft though a viscous coupler of the viscous damper. The rotational driving force of the crankshaft is transmitted to the viscous damper hub through the meshing of a large diameter gear and a driven gear, the viscous damper forming a unit with the driven gear. The rotational driving force is further transmitted to a viscous damper housing through the hub and the viscous coupler, i.e., the viscous coupler including a number of plates which are movable relative to each other in a space filled with silicon oil. The rotational driving force, which is transmitted to the housing and is dampened in torque changes by the function of the coupler, is transmitted to a rotor shaft of an alternator to smoothly rotate the alternator rotor. A smooth performance in driving the accessories is ensured by the viscous damper having the viscous coupler.

摘要： A torque shock or vibrations caused by the rotary inertia of a hydrostatic continuously variable transmission is reduced to improve ride quality of a vehicle when excessive torque occurs in a torque transmission path between a crankshaft and a drive wheel. A motorcycle includes a hydrostatic continuously variable transmission rotatably driven by torque of a crankshaft of an internal combustion engine. A rear wheel is rotatably driven by torque from the transmission. A torque damper absorbs excessive torque occurring in a torque transmission path from the crankshaft to the rear wheel. The torque dampers include an input side torque damper disposed in an input side torque transmission path between the crank shaft and the transmission and an output side torque damper disposed in an output side torque transmission path between the transmission and the rear wheel.

摘要： The degradation of a feeling of ride is prevented by preventing engagement/disengagement (sudden engagement/disengagement) of a motorcycle hydraulic clutch due to a lack of hydraulic pressure. Before a hydraulic sensor issues a hydraulic pressure-lowering detection signal Sx, an oil level sensor issues an oil level-lowering warning signal Sf in a state wherein a sufficient oil quantity is such so as not to bring an neutral drive switching clutch into a disengagement state is present even if hydraulic pressure lowers resulting from an inclined oil level due to sudden deceleration, sudden start, drive in a slope, or the like. Thus, the neutral drive switching clutch can be prevented from disengaging or engaging (suddenly disengaging or engaging).

摘要： A mode changeover control system for a transmission wherein the starting of a vehicle can be prevented even if the transmission is changed over to the drive mode side while a side stand is in an erected position. In a motorcycle including a mode changeover mechanism for a continuously variable transmission, and a side stand, there is provided a changeover operation section changed over by the driver between operation positions corresponding respectively to a drive mode position and a neutral mode position of the mode changeover mechanism. An electronic control unit operates the mode changeover mechanism based on the changeover operation position of the changeover operation section. The control section is configured so as to continually maintain the mode changeover mechanism in the neutral mode position even if the changeover operation section is operated to a drive mode operation position while the side stand is in a stored position.
