Abstract
A new electric mechanical metal belt (chain) continuously variable transmission (EMCVT) for vehicles was studied in this paper. With the use of direct-current (DC) motor controlling the rolling screw, the displacement of the taper disc pressed by the Belleville spring can be controlled, which achieves the function of speed governing. To make sure that the control objectives are realized, the taper disc clamp force control model of the Belleville spring was established by analyzing the speed ratio control model and studying the axial thrust ratio between the driving taper disc and the driven taper disc. So the association model between the CVT transmission ratio under the steady-state condition and the engine speed was proposed. The economic and driving force characteristic curve were determined by tests, and the EMCVT was controlled with the method of the incompletion differential PID control. The validity of models and control strategies were proved by bench tests and road tests.
