Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a hybrid power system of a planetary gear train without a ring gear. Background technique [0002] With the increasing number of automobiles, automobile exhaust pollution has become the main source of urban air pollution. At present, the state has promulgated the "Parallel Management Measures for the Average Fuel Consumption of Passenger Car Enterprises and New Energy Vehicle Credits" to encourage traditional auto companies to accelerate their transformation and vigorously develop new energy vehicles. Affected by policies, more and more new energy vehicles have entered the consumer's field of vision. However, the development of new energy vehicles has a long and bumpy road. Low-carbon life, energy saving and emission reduction are not things that happen overnight. Pure electric new energy vehicles are affected by factors such as inconvenient charging and short crui...
