Problems solved by technology

However, the parallel shaft dual clutch transmission must use a separate reverse shaft and reverse gear
When one output shaft is used, the axial size of the transmission is large; when two output shafts are used, the radial size of the transmission is large and takes up a lot of space, which is not conducive to the structural layout design of the car
At present, the forward gear of dual-clutch transmission adopts 7 gears at most, and the most widely used is 6th gear. When the car shakes, and the engine speed is high at high speed, and the speed ratio changes greatly at the same time, the engine speed changes greatly when changing gears, which makes the power and economy of the car not very ideal, and the ride comfort is poor.

Abstract

The invention discloses a double-clutch-transmission drive mechanism. The double-clutch-transmission drive mechanism comprises a first double-row planetary gear train and a second dual-set planetary gear train, wherein at least one of the two planetary gear trains adopts a CR-CR type gear speed change mechanism and comprises a front planetary gear set and a rear planetary gear set, in the front planetary gear set, a front gear ring is integrated with a rear planetary carrier into a whole through a synchronizer or a clutch, a front planetary carrier and a rear gear ring are integrated into a whole and connected with an output shaft to perform power output, the power is inputted through a front sun gear, or the power is inputted to a rear sun gear or a rear planetary carrier through the synchronizer or the clutch. According to the double-clutch-transmission drive mechanism, the CR-CR type gear speed change mechanism is combined with a Ravigneaux gear speed change mechanism and a Simpson gear speed change mechanism, two clutches and multiple synchronizers are also used in a matched manner, the gear shifting performance of double clutch transmissions is realized, the size of transmissions is reduced, and the gear-shifting smoothness is also improved.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a transmission mechanism of a dual-clutch transmission. Background technique [0002] According to the different types of wheel trains used, there are two types of axle-connected transmissions (parallel shaft transmissions) and axial rotary transmissions (planetary gear transmissions). According to the number of clutches, it can be divided into single-clutch transmission and dual-clutch transmission. The power transmission device of the current dual-clutch transmission is a parallel shaft transmission. The power transmission is divided into two routes, one is the odd-numbered gear transmission route, and the other is the even-numbered gear transmission route. The two power transmission routes pass through the first and second clutches respectively. Connect the first and second input shafts, and then output the power through the transmission gears on the driven s...
