Abstract


Dual - clutch automatic transmission (DCT) the rise in Europe in the late 1990s , following the hydraulic mechanical automatic transmission (AT), electronically controlled automatic mechanical transmission (AMT) , and the stepless automatic transmission (CVT) also a new type of automatic transmission . The dual - clutch automatic transmission, electronically controlled automatic mechanical transmission evolved , inherited many of the advantages of a manual transmission , and a good start shifting performance and fuel economy rapid development . Dual-clutch automatic transmission in the country is just getting started, however, been a great deal of attention due to its excellent performance , and the inheritance of existing production equipment good , has good prospects for development . Starting from the structure of the dual-clutch automatic transmission , systematic and comprehensive analysis of its structure and working principle , and to develop a set of structure and size of the design principles and methods mainly done following aspects of the work : the dual - clutch automatic transmission structure and working principle of the system , a detailed analysis and comparison of the different structure type dual - clutch automatic transmission , their structural characteristics , working principle and principle . Wet double clutch and dual automatic transmission input shaft structural characteristics were analyzed , two typical wet dual clutch friction materials , friction surface dimensions as well as three dual input shaft automatic transmission gear ratio, the center distance of gear parameters and axis structure size and design calculation methods , and generated Mount wet dual clutch start to slip function carried out theoretical derivation . The design method and the determined parameters according to a car on the structure and size of the wet double-clutch automatic transmission design calculations, and draw the structure of FIG . Can be seen that the calculated results and the actual matching , which is basically feasible and reasonable to believe that the design of the dual-clutch automatic transmission developed in this subject .
