Description

technical field [0001] The invention relates to a power and transmission system of a hybrid electric passenger car and a medium-sized truck, in particular to a hybrid coupling transmission device. Background technique [0002] Hybridization can significantly reduce energy consumption and emissions for city buses and urban medium-duty transport trucks. There are many problems in the hybrid direct drive (direct drive system without a gearbox) and P2 scheme (a drive system with a motor embedded in front of the transmission gearbox) in the domestic transmission system design scheme, so they will gradually be adopted based on planetary gears. The hybrid power scheme of the planetary gear system is gradually replaced, but the current hybrid power scheme using the planetary gear system also has many shortcomings. The scheme of gear train coupling has the following problems: [0003] 1. The ring gear of the front planetary gear is connected to the ring gear of the rear planetary g...
