Abstract
A power transmission comprises a continuously variable transmission CVT, which transmits a rotational driving force from an engine E, a starting clutch 5, which variably sets the transmission capacity for the continuously variable transmission CVT, and a control valve CV, which controls the engagement operation of the starting clutch 5. While the engine E is in a partial cylinder operation mode, the control valve CV controls the engagement operation of the starting clutch 5 to attain a predetermined transmission capacity at a rotational speed of the engine that is higher than for a case of the engine in an all cylinder operation mode.
Claims6
A power transmission comprising:
- an engine which includes a plurality of cylinders;
- a drive-power transmission, which transmits a rotational driving force from said engine;
- a frictionally engaging element, which can set variably a transmission capacity for said drive-power transmission;
- and
- a transmission-capacity controller, which controls an engagement operation of said frictionally engaging element;
- wherein:
- while said engine is in a partial cylinder operation mode, said transmission-capacity controller controls the engagement operation of said frictionally engaging element to attain a transmission capacity that is smaller than for a case of said engine in an all cylinder operation mode.
