Abstract
Based on the analysis of the metal V-belt misalignment in the metal V-belt type CVT, the mechanism of the metal V-belt axial-misalignment was discussed and several methods which can eliminate the axial misalignment was introduced. Through more research, the shortages of the bent-generatrix metal V-belt and the method of shifting speed ratio without excursion were pointed out. In order to reduce or eliminate the axial misalignment, an electro-hydraulic control system of metal V-belt type CVT has been designed. Being varieties of the working situation of car and the non-linearity of the electro-hydraulic control system, A Fuzzy PID has been adopted. Then the performance simulation of the electro-hydraulic control system has been conducted. The simulation results showed that the electro-hydraulic control system could eliminate the belt misalignment.
