摘要： A transmission structure of a power unit for a vehicle is provided with a hydrostatic continuously variable transmission for shifting and transmitting driving force from an internal combustion engine to a rear wheel. An oil pump supplies oil to a hydrostatic continuously variable transmission and a neutral/drive switching clutch which is arranged between the transmission and a rear wheel. A hydraulic piston adjacent to each set of driving friction plates and driven friction plates is moved by pressure in an oil pressure chamber and which connects and disconnects the driving force. An oil passage to the neutral/drive switching clutch is branched from an oil passage from the oil pump to the upstream side of the transmission. The resulting configuration prevents a lowering operating pressure of the neutral/drive switching clutch.

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).
摘要翻译： 通过防止摩托车液压离合器由于缺乏液压而导致的接合/分离（突然接合/脱离）来防止行驶感的恶化。 在液压传感器发出液压降低检测信号Sx之前，油位传感器在足够的油量不使中性驱动切换离合器进入脱离状态的状态下发出油位降低警告信号Sf 即使由于突然减速，突然起动，斜坡驱动等导致的倾斜油位导致的液压降低，也存在状态。 因此，可以防止中立驱动切换离合器脱离或接合（突然脱离或接合）。

摘要： An oil pump assembly includes a plurality of pump chambers constituting a plurality of oil pumps, respectively, a plurality of rotors are fitted into the pump chambers, respectively, with a single driving shaft carrying the plurality of rotors to form a single body. Oil pumped up from an oil pan is supplied under pressure to different associated destinations with the relief valves being arranged compactly to reduce the size of the oil pump assembly. Oil pumps are provided with respective relief valves provided to pass oil discharged from the corresponding pump chambers therethrough and the axes of the relief valves are arranged parallel to the driving shaft. A driving shaft is provided on which a plurality of the inner rotors are carried concentrically and integrally. The rotors are connected to the driving shaft and changed depending on discharge oil pressures, thereby preventing the driving shaft from increasing its diameter.

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.
