Embodiment
[0022] see figure 1 , the dual-clutch transmission transmission includes coaxially arranged inner input shaft 1 and outer input shaft 2, a first output shaft 3, and a second output shaft 4, gears are respectively arranged on each shaft, and a first clutch C1 and a second clutch C1 are also included. Two clutches C2, the first clutch C1 is connected to one end of the inner input shaft 1, the second clutch C2 is connected to one end of the outer input shaft 2, and the first clutch C1 and the second clutch C2 are located at the same input end;
[0023] On the inner input shaft 1, a first gear driving gear 11, a fifth gear driving gear 15 and a third gear driving gear 13 are fixedly installed successively.
[0024] Four gears driving gear 24 and two gears driving gear 22 are fixedly installed successively on the outer input shaft 2, four gears driving gear is also used as six gears driving gear simultaneously, and two gears driving gear is also used as reverse gear driving gear si...

The invention relates to gearing of dual clutch transmission. The gearing 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 and four synchronizers; the inner input shaft is respectively provided with a first gear driving gear, a fifth gear driving gear and a third gear driving gear, a fourth gear driving gear on the outer input shaft is also taken as a sixth gear driving gear, a second gear driving gear is also taken as a reverse gear driving gear; a first synchronizer selectively transmits the torques of a first gear and a fifth gear to the first output shaft; a second synchronizer selectively transmits the torque of a fourth gear and the torque of the reverse gearto the first output shaft; a third synchronizer selectively transmits the torque of a six gear and the torque of a second gear to the second output shaft; and the fourth synchronizer selectively transmits the torque of a third gear to the second output shaft. The invention can reduce the axial length of transmission while torque is equivalent; structure is simple, and the quantity of parts is reduced; and cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of automobile transmissions, and in particular relates to a transmission device of a dual-clutch transmission. 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 ...
