Claims
- 1. A hybrid power system with an external auxiliary motor, comprising:
a first power unit that drives a primary shaft; a secondary shaft driven by said primary shaft in a rotational movement, said secondary shaft being parallel to but not in line with said primary shaft, and being positioned on a first side of said first power unit; a first transmission device between said primary shaft and said secondary shaft that transmits torque from said primary shaft to said secondary shaft; an auxiliary power unit comprising an electric motor with a driving shaft positioned on a second side of said first power unit, said driving shaft being parallel to but not in line with said primary shaft or with said secondary shaft; and a second transmission device between said primary shaft and said driving shaft that transmits torque from said electric motor to said primary shaft; wherein said second transmission device comprises; a first wheel mounted on said driving shaft; a second wheel mounted on said primary shaft; and a standard transmission belt connecting said first and second wheels, allowing said first and second wheels to drive each other.
- 2. A hybrid power system with external auxiliary motor according to claim 1, wherein said first power unit is an internal combustion engine.
- 3. A hybrid power system with external auxiliary motor according to claim 1, wherein said electric motor is connected with a rechargeable battery as an energy source to drive said secondary shaft.
- 4. A hybrid power system with external auxiliary motor according to claim 1, wherein said electric motor, when not operating as a motor, generates electricity to recharge a battery.
- 5. A hybrid power system with external auxiliary motor according to claim 1, wherein a signal generator is mounted on said primary shaft for generating timing signals for ignition of said first power unit.
- 6. A hybrid power system with external auxiliary motor according to claim 1, wherein said second transmission device has a chain and two gear wheels, transmitting torque from said electric motor to said primary shaft.
- 7. A hybrid power system with external auxiliary motor according to claim 1, wherein said second transmission device has at least two gear wheels, transmitting torque from said electric motor to said primary shaft.
- 8. A hybrid power system with external auxiliary motor according to claim 1, wherein said first power unit drives a rotational movement of said primary shaft via a transmission box.
- 9. A hybrid power system with external auxiliary motor according to claim 1, wherein a kick starter is mounted on a transmission box or said primary shaft for starting said first power unit.
- 10. A hybrid power system with external auxiliary motor according to claim 7, wherein a kick starter is mounted on a transmission box or said primary shaft for starting said first power unit.
