  • Hybrid power system having CVT
    Patent number: 11198354
    Abstract: A hybrid power system includes a CVT, an internal combustion engine, an electric motor, a clutch, and a synchronization apparatus. The CVT has a CVT input shaft and a CVT output shaft. The internal combustion engine has an internal combustion engine output shaft and the electric motor has an electric motor shaft. The clutch is provided between the internal combustion engine and the CVT. The synchronization apparatus is provided between the internal combustion engine and the electric motor. The clutch and the synchronization apparatus can be adjusted to connect the internal combustion engine output shaft to the electric motor shaft via the CVT, and connect the internal combustion engine output shaft to the electric motor shaft without the CVT. In an example embodiment, the synchronization apparatus includes a first synchronizer between the internal combustion engine and the CVT, and a second synchronizer between the CVT and the electric motor.
