Description

Technical field [0001] The invention belongs to the technical field of hybrid power vehicle power coupling devices, and is characterized by a hybrid power coupling device based on double-row planetary gears with simple structure and high efficiency. Background technique [0002] New energy vehicles, especially hybrid electric vehicles, are considered to be one of the effective ways to solve the problems of vehicle energy saving and environmental protection. By adding additional power sources (such as batteries, super capacitors) and driving devices (such as motors), it not only provides additional power for vehicle driving, but also improves the efficiency of the engine, thereby significantly improving the economic performance and emissions of the vehicle performance. [0003] At present, several models with a high market share of hybrid electric vehicles all use planetary gears as the power coupling structure. For example, the dual planetary hybrid vehicle power coupling system ...
