Abstract

The matching analysis was carried out between automatic transmission (AT) and the friction characteristics of automatic transmission fluid (ATF). The evaluation indexes of shifting elements in AT and the key characteristics of ATF which influenced the evaluation indexes of shifting elements in AT were confirmed. The dynamical model and the dynamic simulation model were built. The calculation and simulation analysis were done for torque capacity, power density, and friction work. The matching requirements between the shifting elements in AT and the friction characteristics of ATF could be obtained. The feasibility, correctness and effectiveness of the method could be proved.
