Abstract
The invention relates to the technical field of transmission, and in particular relates to a transmission, a driving system and a vehicle. The transmission comprises a planetary gear train, a first clutch, a second clutch and a gear box; the gear box comprises a first input shaft and a second input shaft; the first clutch is in transmission connection with the first input shaft; the planetary geartrain is in transmission connection with the second clutch and the second input shaft. Through the planetary gear train, simultaneous input of the two input shafts can be achieved, and through cooperation of the first clutch, the second clutch and the planetary gear train, the number of gears is increased; a first power source matches the planetary gear train through the first clutch, the enginestarting function can be achieved through the planetary gear train, and the development difficulty of starting the first clutch is avoided; in the gear shifting process of the first power source, a second power source can be used for driving torque compensation through the second input shaft, and the gear shifting quality of the driving system is fully guaranteed while the gear increasing and starting functions are achieved.
Description
technical field [0001] The invention relates to the technical field of transmission, in particular to a transmission, a drive system and a vehicle. Background technique [0002] Hybrid power is an important technology for energy saving and emission reduction of automobiles, and hybrid transmission is one of the core technologies in this field. A hybrid transmission with superior performance needs to meet the needs of many aspects, including: small size, low cost, multiple gears, low fuel consumption, good power, good drivability, and high technology availability. At present, there are mainly three technical routes in the industry: a power split system based on dual-motor planetary gears, a parallel system based on single motors, and a series-parallel system based on dual motors. Among them, the single-motor parallel system, especially the gear transmission scheme, has the advantages of low cost, good power and high transmission efficiency, and is widely used. However, in a...
