Abstract

The present invention belongs to the field of mechanical automatic speed variator for vehicle, and is especially one kind of double clutch type automatic gear box in new structure. The automatic gear box includes various setting gear pairs, synchronous shifting unit and shifting control system, and features that each of the power input shaft and the power output shaft is provided with one wet clutch, all the setting gear pairs are divided into odd number set and even number set connected separately to the driven sheet of one of the clutches, and two clutches transmit the work power alternately to realize setting switching. The shift process has no power interruption, short shifting time, greatly raised shifting comfort and excellent shifting power performance and quality of vehicle. The present invention has simple and compact parallel shaft structure, low cost but the same effect as automatic rotary shaft gear box in complicated structure.

Description

technical field [0001] The invention belongs to an automatic transmission in a vehicle, in particular to a dual-clutch automatic transmission with a new structure. technical background [0002] With the rapid development of automobile technology, various forms of vehicle automatic transmission devices have emerged, mainly including: hydromechanical automatic transmission (AT), mechanical continuously variable transmission (CVT), and domestic and foreign are spending a lot of money in recent years The electro-mechanical automatic transmission (AMT) researched by force. In particular, the development of electronically controlled mechanical automatic transmissions is being paid attention to by major automobile factories because of its advantages of high fuel economy, low emission and protection of existing manual transmission production investment required by the development of the automobile industry. [0003] The electromechanical automatic transmission is developed based on...
