| The current trend of automatic transmission is a dual-clutch transmission, from a technical nature is superior to sequential manual gearbox, it is estimated before long will be in the range of large-scale civilian to replace sequential manual gearbox. Mini bus in the use of this type of transmission is basically a blank in order to make this emerging technology in the field of mini-bus to be expanded, it is essential to its use in the minibus on the study.DCT is based on the parallel shaft manual transmission evolved, so it inherited a manual transmission in the high transmission efficiency, installation space, compact, light weight, low price, they also start with the automatic transmission shift quality and characteristics of , has broad prospects for development and application of significant advantages, mainly in the following aspectsDCT transmission power almost without limit, can be widely used in various vehicles. DCT is equivalent to the use of a micro-car was equipped with. Meet the requirements of high-value low-cost mini-bus.As the DCT is based on the manual transmission developed from the power transmission clutches and gears are still relying on complex low level of domestic gear parts manufacturing technology is relatively mature, most transmission manufacturers have a technical basis. DCT technology for the development of the conditions. DCT-producing device can be through the existing manual transmission lines can use a little transformation, so plant products for manual transmission upgrade cycle is short, less new investment, production and inheritance is good.As the demand for a wide range of transmission, DCT technology (automatic control gear technology + technology) applications will not only auto transmission, in other transportation machinery industry, the application can produce the same effect.China's automobile industry started late, but also multi-stage production line to produce manual transmission, mainly in the automatic transmission is in today's high-growth period, domestic car automatic transmission mainly rely on imports, thus improving the development of our DCT products automatic transmission capacity of independent development and will certainly have a positive role in promoting. Also compatible with China's industrial base.This dual-clutch automatic transmission for the study done the following research areas:1,Using CRUISE software factory for a certain type of mini-buses with the MT engine of the vehicle transmission model, and has done a vehicle power, fuel economy of the simulation, the simulation results were compared with experimental results;2,In a typical dual-clutch automatic transmission, structural analysis and working principle of the study, using CRUISE software factory for the DCT-based mini-bus model, design the corresponding shift of strategy, a simulation calculation;... |
