A Simulation of the Oil Film Based Power Transmitting Process in HT-CVT

Taking into accounts the more and more stringent requirement for the reduction of the emissions while improving the power and economy performance of vehicles, the HT-CVT has been taken as the object of the research in this paper. The power transmitting oil film model and the oil film power-transmitting model have been established. The oil film developing process and the oil film power transmitting characteristics were analyzed by calculation. After comparing with the experimental results, it is shown that the models are effective and accurate, and can be used in the computer based design of HT-CVT.
