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
The currently used dual-clutch transmission has a large speed ratio change, so that the engine speed changes greatly when shifting gears, which makes the ride comfort of the car poor.

[0023] see figure 1 , the dual clutch of the present invention includes a dual clutch assembly 1 (comprising a first clutch 2 and a second clutch 3, respectively corresponding to the first input shaft 4 and the second input shaft 5 of the two clutches), the first double-row planetary gear train 181, The second double-row planetary gear train 182, the output shaft 6 and a plurality of synchronizers. The first double-row planetary gear train and the second double-row planetary gear train are arranged in a vertical structure. The first double-row planetary gear train adopts a new double planetary gear transmission mechanism, and the second double-row planetary gear train adopts a Simpson gear transmission mechanism. The first double-row planetary gear train includes a first planetary row X1 and a second planetary row X2, and the second double-row planetary gear train includes a third planetary row X3 and a fourth planetary row X4.

[0052] see image 3 , On the basis of the first embodiment, the dual-clutch assembly 1 is placed on the right side of the first double-row planetary gear train, and the positions of other components remain unchanged. The dual-clutch assembly 1 and the output shaft 6 are on different sides and not on the same axis. According to the transmission ratio setting of gears, the transmission ratios of the first gear 261 and the second gear 262 , the third gear 263 and the fourth gear 264 , and the value a of each planetary row need to be appropriately changed. The first double-row planetary gear train 181 realizes 2.4.6 gear like this, and the second double-row planetary gear train 182 realizes 1.3.5 and reverse gear.

Abstract

The invention discloses a transmission device for a six-speed dual-clutch transmission, which includes first and second double-row planetary gear trains, one of which is composed of two planetary rows, front and rear. , the front sun gear is integrated with the rear planet carrier, and is fixed with the housing through the first constant mesh synchronizer or clutch; the rear planetary row adopts a double planetary gear structure, the front ring gear and the rear ring gear are integrated, and the power can be passed through the second The second synchronizer or the third synchronizer or clutch is transmitted to the rear sun gear or rear ring gear through the first rear outer shaft, and is output by the front planet carrier; the other double-row planetary gear train adopts a Simpson gear transmission mechanism, and the front sun gear It is integrated with the rear sun gear and connected with the second outer shaft sleeve, and the front ring gear is connected with the second intermediate shaft. The invention adopts the combination of the Simpson type and the novel double planetary gear speed change mechanism to realize more gear ratios and reduce the size of the speed changer.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a transmission device of a six-speed 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 d...
