Hybrid electric vehicle (HEV) has been invented and developed over the past two decades. It is the promising solution for cutting down emission and reducing pollution besides electric vehicles. Since a series hybrid vehicle needs no transmission, the transmissions of parallel and series-parallel hybrid systems are studied nowadays. This paper presents a design approach for the configuration synthesis of series-parallel hybrid transmissions with the eight-link Ravigneaux mechanisms. The synthesis process subject to the concluded design consist of 7 mechanisms with eight members and twelve joints including the combination of two planetary gear trains. Then, by using the techniques of power and clutch arrangements, new series-parallel hybrid transmissions are synthesized with 27 clutchless hybrid systems and 27 corresponding series-parallel hybrid transmissions. A new hybrid transmission is selected as an example to demonstrate the feasibility of the synthesized configurations by analyzing the working principle with operation modes and power flow paths.
