“…Therefore, the Hy-Vo chain is extensively applied to areas of heavy loads and high speeds, such as the transfer case in hybrid vehicles. The previous studies have already proved that the internal-external composite meshing mechanism is the best way to improve the transmission performance of a round pin jointed silent chain system [3]. When an external meshing Hy-Vo chain meshes with a sprocket with the involute profile, because the essence of the external meshing is a kind of positioning, the meshing impact between the chain plate external profiles and the sprocket involute profiles is not avoidable [4].…”

The internal–external composite meshing mechanism should be the best way to improve the transmission performance of a silent chain drive, but there is no internal–external composite meshing Hy-Vo chain under the classical design approach. In this research, by building the Hy-Vo chain meshing system, the difference between the meshing of the chain–sprocket and the meshing of the rack–gear is deeply analyzed. By rigidifying the external meshing Hy-Vo chain as a rack, the fluctuation range of the pitch line of the external meshing Hy-Vo chain is analyzed. Based on the relations between the actual chain pitch line and the rigid chain pitch line, the design method for the internal meshing profile of the internal–external composite meshing Hy-Vo chain is deduced, the necessary conditions are obtained, and the meshing characteristics are analyzed. By conducting comparative multi-body dynamics experiments, the results prove that the design method of the internal–external composite meshing Hy-Vo chain proposed in this study is effective and feasible. The results also show that the description of the internal–external composite meshing in the classical meshing theory is not completely correct. In fact, the internal–external composite meshing mechanism cannot reduce the meshing impact of the Hy-Vo chain system and can only improve the system polygon action, the meshing performance, and the transmission stability.
