Thirty-two novel hybrid transmissions consisting of a Ravigneaux gear train and a single planetary gear train are synthesized using a creative design methodology based on graph-theory and the lever analogy method.The design process commences by identifying an existing transmission configuration which meets all veuve ambal rose of the design requirements.The chosen design is then used to synthesize all possible mechanism permutations which satisfy the design constraints.

The feasible mechanisms which satisfy both the design requirements and the design constraints are converted into analogous levers.The levers which fail to provide the required operation modes of the hybrid transmission are eliminated and the remaining levers are assigned brakes and clutches ice blue graphic tee in order to realize the final designs.The responsiveness of the new hybrid transmissions and the feasibility of the proposed design methodology are confirmed by analyzing the power flow and kinematics of one of the designs in all of the operation modes.
