| Abstract: | Continuously variable transmission(CVT) of metal V-belt is an ideal transmission for automobile. Working principle of metal V-belt CVT is explicated, development trend of eletro-hydraulic control technology of metal V-belt at home and abroad is introduced, and electro-hydraulic control system of metal V-belt is also designed. Some key issues of metal V-belt CVT are analyzed in detail, including speed ratio control and clamping force control, consolidated control of CVT and engine, transmission efficiency of CVT etc., and a conclusion is drawn that electro-hydraulic control technology is one of the important development trends of metal V-belt CVT. |
