HYBRID DRIVE ASSEMBLY FOR A VEHICLE, IN PARTICULAR A SCOOTER |
摘要 |
A hybrid drive assembly ( 1 ) for a vehicle having at least one drive wheel ( 2 ), the drive assembly including an internal combustion engine ( 3 ); a transmission unit ( 5 ) interposed between a drive shaft ( 4 ) of the internal combustion engine ( 3 ) and a propeller shaft ( 6 ) connected angularly to the drive wheel ( 2 ), and in turn including a continuously variable transmission ( 7 ) having a drive pulley ( 10 ) connected angularly to the drive shaft ( 4 ) and a driven pulley ( 11 ), and a centrifugal clutch ( 8 ) having a hub ( 20 ) connected to the driven pulley, and a driven bell ( 26 ) connected to the propeller shaft ( 6 ); and an electric machine ( 32 ) having a rotor ( 35 ) integral with the bell ( 26 ) of the centrifugal clutch ( 8 ). The drive assembly ( 1 ) is controlled by a control unit ( 38 ), in response to a number of input signals (Ss, Sa, Sf), in a number of operating modes including an all-combustion propulsion mode, an all-electric propulsion mode, a first hybrid propulsion mode wherein the internal combustion engine ( 3 ) and the electric machine ( 32 ) are connected in series, and a second hybrid propulsion mode wherein the internal combustion engine ( 3 ) and the electric machine ( 32 ) are connected in parallel. |
