Description

technical field [0001] The invention belongs to the technical field of power transmission of hybrid electric vehicles, in particular to a dual-output hybrid transmission driving device that can be applied to automobiles to realize four-wheel drive. Background technique [0002] In recent years, due to the increasingly scarce fossil resources and the increasingly prominent environmental pollution problems, the energy saving and environmental protection of automobiles have attracted the attention of governments and people all over the world. Governments of all countries have formulated increasingly stringent fuel economy and emission regulations to Limit vehicle fuel consumption and exhaust emissions. In China, with the implementation of the National V emission standards in 2017, nitrogen oxides, hydrocarbons, carbon monoxide and suspended particles produced by vehicle exhaust in air pollution will be reduced, while air pollution problems such as smog will be reduced. To a ce...
