A specific embodiment of the invention discloses a hybrid-electric transmission which is used for connecting an engine, a first motor and a second motor with a power output shaft. The transmission comprises a first planet row and a second planet row, a gear ring of the first planet row is connected to the engine, the first planet row and the second planet row share the same planet carrier, the planet carrier is connected to the first motor, a sun gear of the first planet row is connected to the second motor, and a gear ring of the second planet row is connected to the power output shaft. Another specific embodiment of the invention further provides a hybrid-electric vehicle. The hybrid-electric transmission and the hybrid-electric vehicle are provided with double-planet-row mechanisms, and can realize stepless speed change. Besides, input torque of the engine, input torque of the first motor and input torque of the second motor are transmitted to output ends after being coupled, and are finally transmitted to wheels, so that various output modes can be realized by combining different working modes and states of the three input ends during actual usage.
Description
technical field [0001] The invention relates to a hybrid vehicle, in particular to a transmission device of the hybrid vehicle. Background technique [0002] Due to the shortage of energy and the enhancement of public awareness of environmental protection, environmentally friendly electric vehicles or fuel cell vehicles have emerged. However, due to technical constraints, it is difficult to fully promote the above types of vehicles in a short period of time. Therefore, technically mature hybrid vehicles Powered cars are an ideal choice at present. [0003] Hybrid-Electric Vehicle (HEV, Hybrid-Electric Vehicle), as an emerging energy-saving and environmentally friendly vehicle, its technology and market are in a stage of vigorous development. Compared with traditional vehicles and pure electric vehicles, the biggest difference between hybrid vehicles and pure electric vehicles is power. system. For parallel and hybrid HEVs, the power coupling system is responsible for combi...
