Embodiment Construction
[0016] An example of the present invention is figure 1 As shown, it is a double planetary confluence type multi-clutch transmission used in a tractor, including a housing 10, a main input shaft 2 connected to the output shaft of the engine 1, a first sun gear input shaft 33, and a The main output shaft 31 of the external output torque, the first multi-clutch, the second multi-clutch and the double planetary row confluence mechanism also include the corresponding clutch operating mechanism 46, the gear selection operating mechanism 36, the rotational speed sensor 6 and the electronic control unit 37 and other components of the transmission control system.
[0017]Both the first multi-clutch and the second multi-clutch include an input end coaxially connected to the main input shaft 2, two clutch output shafts, and a clutch mechanism for selecting the input end to be connected to one of the clutch output shafts. The input end, the corresponding clutch output shaft and the clutc...

The invention relates to a double-planet row converging type multi-clutch transmission which can meet multi-gear needs. The double-planet row converging type multi-clutch transmission comprises a main input shaft, a main output shaft, a first multi-plate clutch, a second multi-plate clutch and a double-planet row converging mechanism. The first multi-plate clutch and the second multi-plate clutch respectively comprise an input end, more than two clutch output shafts and a clutch mechanism. A first planet row 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 a main shaft output shaft. More than two gear selecting and shifting gear sets are arranged between each output shaft of the first multi-plate clutch and the first sun wheel input shaft, more than two gear selecting and shifting gear sets are arranged between one clutch output shaft in the second multi-plate clutch and the first planet carrier input shaft, and more than two gear selecting and shifting gear sets are arranged between the other clutch output shaft in the second multi-plate clutch and a second gear ring input shaft. Each gear selecting and shifting gear set comprises free gears, and a synchronizer is arranged between two adjacent free gears arranged in pairs.
Description
technical field [0001] The invention relates to a dual-planetary confluence multi-clutch transmission. 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 transmission shaft or the even-n...
