The invention relates a transmission device for a dual clutch speed changer. The device comprises an inner input shaft and an outer input shaft which are coaxially arranged, as well as a first output shaft, a second output shaft, gears on each shaft, two clutches, four synchronizers and a reverse gear shaft, wherein three-gear drive gears are simultaneously used as five-gear drive gears; four-gear drive gears are simultaneously used as six-gear drive gears, and the two-gear drive gears are simultaneously used as reverse gear drive gears; bushing of the reverse gear shaft is provided with a reverse gear idle gear; the first synchronizer selectively transfers a first gear torque and a third gear torque to the first output shaft; the second synchronizer selectively transfers a fourth gear torque and the reverse gear torque to the first output shaft; the third synchronizer selectively transfers a sixth gear torque and a second gear torque to the second output shaft; and the fourth synchronizer selectively transfers a fifth gear torque to the second output shaft. Under a condition that the torques is equivalent, the axial length of the speed changer can be shortened; when multiple pairs of gears are used in common, the speed ratio distribution of the speed changer can be optimized.
Description
technical field [0001] The invention belongs to the technical field of automobile transmissions, and in particular relates to a double-clutch transmission transmission device. Background technique [0002] A typical dual-clutch transmission means that two clutches are respectively connected to two input shafts to transmit engine power. The dual-clutch transmission consists of two coaxial nested or parallel clutches, two coaxial, inner and outer nested input shafts, two parallel output shafts, multiple synchronizer devices arranged on the output shafts, It consists of multiple shift forks and a differential. The odd and even gear input gears of the transmission are respectively arranged on the two input shafts, through the switching of the two clutches and the actions of different synchronizers, the torque conversion and output are realized through different output shafts. Dual-clutch transmissions are mainly used in passenger cars. The problem with existing dual-clutch tra...
