In this paper, a methodology on the topological synthesis of admissible non-fractionated differential geared mechanisms for automotives is presented. Based on the characteristics of differential geared mechanisms, characteristics of non-fractionated differential geared mechanisms are laid out. Admissible non-fractionated differential geared mechanisms can be identified from atlases of geared kinematic chains by checking the redundancy condition in a kinematic equation governing the terminals. The methodology presented here is systematic and efficient, and can be easily applied to the enumeration of innovative non-fractionated differential geared mechanisms.
