Discussion on the Developmental Situation of DCT Automatic Transmission LIN Zhi-qiang (Heilon i g kngshi Tour Mobile serve CoLtd Harbin 150090) Abstract: This paper introduces the dual clutch automatic transmission Dual clutch Transmission (DCT) development and application status at home and abroad. The working principle, structure characteristics were analyzed, the DCT manual transmission efficiency high characteristic and hydraulic power shift automatic transmission, transmission is Chinas most promising. Key words: dual clutch/automatic transmission The car is a unity composed of multi system. The transmission system is one of the key auto systems, and improve the degree of good or bad performance, plays a decisive role in the automobiles power performance, economy, comfort and reliability. Automobile transmission system technology is gradually developed from manual to automatic gear shift, especially the application of computer technology in transmission system, automatic transmission technology has been rapid development. The modern automobile transmission mainly has four types: electronic automatic mechanical transmission (AMT), continuously variable transmission (CVT), hydraulic mechanical automatic transmission (AT) and dual clutch automatic transmission (DCT), they all have different performance characteristics. AT and cVT no power interruption when shifting gear, with good quality, but the mechanical efficiency is low, leading to poor fuel economy vehicles; mechanical efficiency of AMT is high, but when the shift to interrupt the power transmission, shift smoothness and affects the dynamic p
