With the aggravation of environmental pollution and energy crisis, new energy vehicles have become a new development trend in the automotive industry, and the power coupling mechanism of hybrid electric vehicles is one of the key research areas of new energy vehicles. In this paper, a new type of dual-planetary row coupling mechanism is introduced, and its structure and working mode are analyzed. The power flow analysis of the dual-planetary row coupling mechanism is carried out by combining the lever method with the block diagram of power flow. The main factors of generating power cycle in the system are determined. The analysis method and basis are provided for the optimal design of the dual-planetary row coupling device.
