Abstract
The application relates to a front-drive three-gear hybrid transmission system and a vehicle, which comprises an electronic continuously variable transmission, a three-gear gear coupling mechanism and a vehicle. The electronic continuously variable transmission comprises a planetary gear mechanism composed of a sun gear, a planet carrier and a ring gear, and an engine in transmission connection with the planet carrier, a front-drive motor in transmission connection with the sun gear and a ring gear intermediate shaft in transmission connection with the ring gear. The three-gear gear coupling mechanism comprises an intermediate transmission shaft arranged in parallel with the ring gear intermediate shaft, a first gear pair and a second gear pair which are sleeved on the intermediate transmission shaft and in transmission connection with the ring gear intermediate shaft, and a first gear shifting mechanism for combining or separating the first gear pair and the second gear pair. The three-gear gear coupling mechanism also comprises a third gear which is sleeved on the intermediate transmission shaft and in transmission connection with the ring gear, and a second gear shifting mechanism for combining or separating the intermediate transmission shaft and a transmission case. The application matches only one multifunctional front-drive motor which can realize pure electric driving, power split and series power generation, so that the total cost of the transmission assembly of the vehicle is effectively reduced.
