The invention relates to a lift-drag type vertical axis wind driven generator based on an overrunning combined mechanism, in particular to a lift-drag type vertical axis wind driven generator aiming at the problems of low generating efficiency, poor stability and low reliability of a lift-drag combined type vertical axis wind driven generator. A drag force wind rotor is arranged on a second drag force wind rotor shaft; a first lift force wind rotor shaft and a second lift force wind rotor shaft are arranged in a first drag force wind rotor shaft and the second drag force wind rotor shaft; thesecond lift force wind rotor shaft is connected with the first lift force wind rotor shaft through a first coupling; the first lift force wind rotor shaft and the first drag force wind rotor shaft are provided with a lift force wind rotor and the drag force wind rotor; the overrunning combined mechanism is fixed between the first lift force wind rotor shaft and the first drag force wind rotor shaft; the second lift force
