The binary logic transmission technology is a technological innovation in the field of vehicle transmission. Based on the original technology of new double internal meshes gear drive, multi-cone shift friction elements and reconfigurable strong module domain structure, it can achieve purely mechanical, efficient, ultra-multi-gear (32 or 64) quasi-stepless transmission under the condition of strong volume and weight constraints. For the binary logic mechanical dual-power-flow transmission, a four-compound planetary row-type power flow coupling mechanism with a comprehensive flow discharge and coupling mechanism has been proposed to establish a sports and dynamic computing model with the principles of planet transmission. A mathematical model of vehicle driving and steering based on ground dynamics is established by using the driving principle of tracked vehicle, and the driving performance is analyzed and verified under specific road surface. The analysis shows that this coupling mechanism can fit the binary logic mechanical transmission type, reduce the power demand of the steering shunt, and provide great convenience for the continuous increase of the power density of the transmission device.
