Abstract:
Several key problems in the research and development of
continuously variable transmission for automobile, such as those
connected to the transmitting frictional pair and the related
automatic tightpressing actuator, the transmission ratio control
logic and the related automatic control system, are discussed.
The strategies taken for solving these key problems are
described.
Key words: Continuously
