  • Hybrid power system
    Patent number: 6663524
    Abstract: A hybrid power system, comprising a first power unit, a secondary shaft, a speed converter, a clutch, and an electric motor. The first power unit has a primary shaft. The secondary shaft is driven by the primary shaft in a rotational movement. The speed converter is placed between the primary shaft and the secondary shaft, having a transmission belt, transmitting torque from the primary shaft to the secondary shaft. The clutch is set on the primary shaft or on the secondary shaft, allowing or interrupting transmission of torque from the first power unit to the secondary shaft. The electric motor is connected with the secondary shaft, either driving the secondary shaft or being driven by the secondary shaft to generate electricity or running idle.
    Type: Grant

  • Hybrid power system with continuously variable speed
    Patent number: 6659910
    Abstract: A hybrid power system with continuously variable speed, comprising a first power unit, a secondary shaft, a speed converter, a clutch, a second transmission device, and an electric motor. The first power unit has a primary shaft. The secondary shaft is driven by the primary shaft in a rotational movement. The speed converter is placed between the primary shaft and the secondary shaft, having a transmission belt, transmitting torque from the primary shaft to the secondary shaft. The clutch is set on the primary shaft or on the secondary shaft and has a drum, allowing or interrupting transmission of torque from the first power unit to the secondary shaft. The second transmission device is connected with the drum of the clutch. The electric motor is connected with the secondary shaft, either driving the secondary shaft or being driven by the secondary shaft to generate electricity or running idle.
