The transmission system of the inverse differential gear

This research is aimed to improve the transmission system of the inverse differential gear type of hybrid electric motorcycle and to analyze the vehicle’s overall performance.


I refit a motorcycle with traditional Internal Combustion Engine (ICE), and make the integrated motor/generator and traditional ICE as its two output power sources with different characteristic; making use of the power integrating/distributing mechanism of inverse differential gear to integrate the single/dual power or to distribute the power output; installing eCVT (electrical Continuously Variable Transmission) to automatically adjust the reduction ratio of transmission gear according to the driving condition, thus the ICE can keep operating in the best operating range, and recharge the surplus power produced by engine through the action of switching from the motor mode to the generator mode, by doing so to efficiently decrease the fuel consumption and increase the range of the motorcycle.
