| Abstract: | Development history and research status of continuously variable transmission (CVT) is explicated. From technique aspect, the basic structure of metal v-belt CVT is introduced,then the structure and principle of the metal belt and chain is compared. The paper presents the principle and performance of the mechanical-hydraulic control system and electro-hydraulic control system, especially the slip control strategy developed recently. CVT advantages are presented. From application aspect, CVT key manufacturers are enumerated, and CVT automobiles in China market are summarized. Future CVT market potential and its development trend are predicted. |
