| Abstract: | A design method on a new continuously variable transmission system with reflux power was proposed. The transmission efficiency and ratio changing range in this design method were defined to the design standards. The design targets were estabtished to keep the transmission efficiency to be higher than 80 percent in deferent driving modes, and the stable working point of the engine running alone the optimal fuel economy at different oil pedal openings. The key structural parameters were calculated to the continuously variable transmission system with reflux power for CHANA SC7101 car. it provides a design method for developing a new continuously variable transmission system. |
