Abstract

The invention provides a transmission device used for a longitudinally-arranged rear-drive hybrid electric vehicle. The transmission device comprises a first electric motor (EM1), a second electric motor (EM2), an input shaft, a first brake (B1), a second brake (B2), a first clutch (C1), a second clutch (C2) and a planetary gear coupling mechanism; the planetary gear coupling mechanism comprises asingle planetary gear row (PG1) and a double planetary gear row (PG2); and an engine is connected with the planetary gear coupling mechanism through the first clutch (C1), the second clutch (C2), thefirst brake (B1), the second brake (B2), the first electric motor (EM1) and the second electric motor (EM2) so as to achieve various pure electric and hybrid electric driving modes. According to thetransmission device used for the longitudinally-arranged rear-drive hybrid electric vehicle, the structure is compact, matching work with the engines with different displacement can be realized, and the torque demand and manufacturing cost of the electric motors are reduced.

Description

technical field [0001] The invention relates to a transmission device for automobiles, in particular to a transmission device for a longitudinal rear-drive hybrid vehicle. Background technique [0002] Due to the aggravation of the world's environmental and energy problems caused by traditional fuel engine vehicles, and the adjustment of new energy vehicle policies in various countries around the world, major automobile companies are actively developing energy-saving and environmentally friendly vehicles. The hybrid power system has become a feasible technical solution to solve automobile energy consumption and environmental pollution at this stage, and its core power transmission device has become the focus of research and development by various companies. At present, most of the longitudinal hybrid schemes use multiple single planetary rows for series-parallel hybrid schemes, but the fuel saving efficiency is limited. Therefore, a transmission device that is more fuel-eff...
