Description

Technical field [0001] The invention relates to an automobile transmission, in particular to an integrated hydraulic torque converter and a group of differential planetary gears to realize a hydraulic planetary automatic continuously variable transmission for continuously variable transmission of automobiles. Background technique [0002] Continuously variable transmission is the highest goal of automobile transmission. The only CVT used in automobiles is "metal belt continuously variable transmission". It has a complex structure, limited transmission power, and its application range is not wide at present. The others are stepped automatic transmissions. Realize the present application of stepless speed change transmission by gear and do not have yet. Contents of the invention [0003] The invention provides a hydraulic planetary automatic continuously variable transmission, which is directly driven by a differential planetary transmission, controlled by a comprehensive h...
