Problems solved by technology
The automatic mechanical transmission (AMT) is based on the manual transmission, adding an automatic control device to control the clutch and select the gear pair on the fixed shaft system for automatic shifting. During the shifting process, there is power interruption phenomenon, and the shifting smoothness not good
The electro-hydraulic automatic transmission (AT) has a series of planetary gear trains and multiple clutches and brakes, which can automatically shift gears through electronically controlled hydraulic drive, but the structure and control system are complicated, the transmission efficiency is low, and the parts are difficult to process Large, high manufacturing and maintenance costs
The mechanical continuously variable transmission (CVT) can realize continuous stepless speed regulation, but the transmission torque is small, the processing and manufacturing precision of the parts is high, the manufacturing is

The invention relates to a dual clutch type variable transmission device with a planetary gear train. The device consists of a sun axle, a first countershaft, a second countershaft, an intermediate shaft, dual clutches, a synchronizer, a gear and a planetary gear train, by the combination of the planetary gear train, the dual clutches, the synchronizer and the gear, automatic smooth gear shifting can be realized; and by a structure of the planetary gear train and the sharing gear, the gear number is greatly increased, and the number of shift gears can be reduced. Each pair of gears has less small speed ratio and is in a short transmission shaft structure, so the rigidness of a speed changer is improved, and the radial and axial sizes of the speed changer are reduced; a cylindrical gear is used for replacing a conical gear, so a differential mechanism has a compact structure, the manufacture cost of the differential mechanism is reduced, the gear axial pressure of the conical gear differential mechanism is eliminated, and the transmission efficiency of the differential mechanism is improved.
Description
technical field [0001] The invention relates to a double-clutch speed change transmission mechanism, in particular to a double-clutch speed change transmission device with a planetary gear train. Background technique [0002] Currently, there are three main types of automatic transmissions used in automobiles: hydraulic automatic transmission (AT), electromechanical automatic transmission (AMT) and mechanical continuously variable automatic transmission (CVT). In the field of electronically controlled mechanical automatic transmission, there is also a variable speed transmission method, that is, dual-clutch automatic transmission (DSG). The automatic mechanical transmission (AMT) is based on the manual transmission, adding an automatic control device to control the clutch and select the gear pair on the fixed shaft system for automatic shifting. During the shifting process, there is power interruption phenomenon, and the shifting smoothness not good. The electro-hydraulic ...
