In order to identify all the appropriate system schemes for the compound split systems formed primarily with a four-port mechanical power split device,power transmission characteristics of the compound split systems was analyzed.Considering the structural symmetry and according to the different connection arrangement of the four ports,compound split system was classified into four types.Using black-box modeling method,the generalized models of the speed ratio,the torque ratio and the power split ratio were established.Moreover,a semi-invert diagram was used to distinguish the different schemes in each type.The characteristics of the speed ratio,the torque ratio and the power split ratio in each domain were also analyzed and compared.Through the semi-invert diagram,a selection method based on the rated-power speed ranges in different schemes was presented and all suitable compound split systems were identified,which can be used as references for the scheme selection of this kind of continuously variable power split transmission.
