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 the dual-clutch transmission adopts 7 gears at most, and the most widely used is the 6th gear, and the speed ratio changes greatly. In this way, the engine speed changes greatly when changing gears, which makes the power and economy of the car not very ideal. poor ride quality

Abstract

The invention discloses a multi-speed planetary gear type double-clutch gearbox which comprises a first clutch, a first input shaft corresponding to the first clutch, a second clutch, a second input shaft corresponding to the second clutch, a plurality of synchronizers and an output shaft, wherein the first input shaft and the second input shaft are arranged in a sleeving way; the multi-speed planetary gear type double-clutch gearbox also comprises a first double-row planetary gear train, a second double-row planetary gear train, a first gear, a second gear, a third gear and a fourth gear, wherein the first gear is meshed with the second gear; the third gear is meshed with the fourth gear; one of the first double-row planetary gear train and the second double-row planetary gear train is formed by two planet rows; in the front planet row, a front sun gear is connected with a rear planet carrier into a whole, and is fixed with a shell by the first constant mesh synchronizer or the clutches; the rear planet row adopts a double-planet wheel structure; a front gear ring is connected with a rear gear ring into a whole; the power is transmitted into a rear sun gear or the rear gear ring by the second synchronizer, the third synchronizer or the clutches through a first rear outer shaft, and is output by a front planet carrier. The multi-speed planetary gear type double-clutch gearbox can realize more speed ratio gears by fewer gear pairs, reduces the size of the gearbox, and enables the structural layout design of an automobile to be more flexible.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a multi-speed planetary gear 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 mechanism 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...
