Transmission system design of dual-mode power split type hybrid electric vehicle
For the configuration of dual-mode power split type hybrid electric vehicle transmission system,first the structural char-acteristics and application range of single and dual mode hybrid electric systems are compared and analyzed.Secondly,based on the characteristics of composite allocation,three types of composite allocation four node rod models are selected,and all feasible composite allocation configurations are obtained through reverse splitting.The configuration scheme is determined based on the constraint conditions of rod length and characteristic parameters.On this basis,referring to the parameters of a certain vehicle model,by analyzing the input distribution mode,mode switching point,and mechanical point characteristics,the position and structural parameters of the third row planetary gear and clutch are determined.The final design of the transmission system config-uration provides a theoretical basis for studying the dual-mode power split hybrid power vehicle transmission system.
