Abstract: The
most remarkable
characteristic of a metal belt-planetary gear continuously
variable transmission is a wider ratio range and a bigger torque
capacity than a conventional metal pushing belt continuously
variable transmission. A parallel hybrid car with this
transmission system not only can reduce fuel consumption and
pollutant emission at a ECE city cycle, but also can keep the
motor working in the most efficiency area and can be started by
a lower power motor by oneself. At the same time, the
continuously variable transmission system can realize the smooth
switch between the motor and the engine.
Key words: Hybrid
