PROBLEM TO BE SOLVED: To create a speed change gear for an automobile making it possible to execute an automatic shift process without accompanying cut-off of propulsion force and realize a wide range of versatile function in various shift systems. SOLUTION: The input shaft 12 of planet gear transmission devices 13-16 is connected to a crankshaft 11 of an internal combustion engine. Both output shafts 17, 18 of the planet gear transmission devices 13-16 are connected to two counter shafts 28, 29 and also connected to two counter shafts 28, 29, and also connected to two rotors 20, 21 of the electric driving part and these rotors can operate as motors and generators. Accordingly, these both rotors have functions of conventional starter and generator and enable the process control of the connected shift transmission device. |
