The invention discloses a power coupling module based on a dual-clutch transmission of a parallel type hybrid power transmission scheme. A traditional dual-clutch transmission comprises two clutches and two power input shafts. On the basis that a variable gear transmission part of the dual-clutch transmission is hardly changed, one input shaft of a clutch standing-connecting transmission is replaced by a motor; a wet clutch is arranged between the other input shaft and an engine; a locking ring type synchronizer is arranged between the two input shafts. Key transmission parts including the wet clutch, the locking ring type synchronizer and the motor are sequentially arranged behind the engine. In this way, the parallel type hybrid power transmission system according to which the engine and the motor can drive a wheel along different paths respectively is formed. Although only one wet clutch is arranged, power-interruption-free driving on the wheel can be achieved as well with the help of the motor in the gear shifting process of the engine.
