Abstract

The invention relates to a double-planet-row converging type multi-clutch speed variator which can meet multi-gear needs. The double-planet-row converging type multi-clutch speed variator comprises a main input shaft, a main output shaft, a multi-plate clutch and a double-planet-row converging mechanism. The multi-plate clutch comprises an input end, at least two clutch output shafts and a clutch mechanism. A first planet row of the double-planet-row converging mechanism comprises a first sun wheel input shaft and a first planet carrier input shaft, a second planet row comprises a second gear ring input shaft, a second planet carrier is in coaxial transmission connection with a first gear ring, and a second sun wheel is in coaxial transmission connection with the main output shaft. Each clutch output shaft comprises an even-number gear clutch output shaft and an odd-number gear clutch output shaft, an odd-number gear selecting and shifting gear set is arranged between the odd-number gear clutch output shaft and the first planet carrier input shaft, and an even-number gear selecting and shifting gear set is arranged between the even-number gear clutch output shaft and the second gear ring input shaft. A first sun wheel input shaft speed variator used for changing the rotating speed of the main input shaft into more than two kinds is arranged between the first sun wheel input shaft and the main input shaft.

Description

technical field [0001] The invention relates to a multi-clutch speed change device of double planetary row confluence type. Background technique [0002] At present, the transmission technology is developing rapidly, especially the dual-clutch automatic transmission, which has been relatively mature and has been used more and more recently because it can better solve the problem of power transmission interruption. For example, the application number is 20082009555.6, and the announcement number is CN201265630Y, which discloses a dual-clutch five-speed automatic transmission, including a main input shaft for connecting a power source, a dual clutch connected with the main input shaft, an intermediate shaft and a main output The dual clutch includes an input end coaxially connected with the main input shaft, an odd-numbered transmission shaft, an even-numbered transmission shaft, and a clutch mechanism for selecting the input end to be connected to the odd-numbered transmissio...
