The invention relates to a planet busbar type multi-shaft clutch speed-changing device. The planet busbar type multi-shaft clutch speed-changing device has the functions of high-gear output, low-gear output and reverse-gear output to meet the requirements for multiple gears. The planet busbar type multi-shaft clutch speed-changing device comprises a main input shaft, a main output shaft, a first multi-shaft clutch, a second multi-shaft clutch and a planet busbar mechanism, wherein the first multi-shaft clutch and the second multi-shaft clutch respectively comprise an input end, a plurality of clutch output shafts and a clutch mechanism, the planet busbar mechanism comprises a sun wheel input shaft and a planet frame input shaft, a gear ring is coaxially connected with the main output shaft in a transmission mode, more than two first gear-shifting gear sets are arranged between the clutch output shafts of the first multi-shaft clutch and the sun wheel input shaft, more than two second gear-shifting gear sets are arranged between the clutch output shafts of the second multi-shaft clutch and the planet frame input shaft, the first gear-shifting gear sets and the second gear-shifting gear sets respectively comprise an empty sleeve gear, a synchronizer is arranged between every pair of empty sleeve gears arranged side by side, and a period-speed switchover synchronizer is arranged among the sun wheel input shaft, the planet frame input shaft and a shell body.
Description
technical field [0001] The invention relates to a planetary row confluence type multi-clutch speed change device. 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 double clutch includes an input end for coaxial transmission connection 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 an odd-numbered tran...
