Hybrid transmission module and hybrid electric vehicle

The utility model provides a hybrid transmission module and a hybrid electric vehicle. The hybrid transmission module comprises a motor (1), an engine (2), a planetary mechanism (4), an infinitely-variable-speed mechanism (3), a speed reducing mechanism (15) and an output shaft (16). The planetary mechanism (4) comprises a planet carrier (8) and a sun gear (7), a power output end of the motor (1) is connected with the planet carrier (8), an input end of the infinitely-variable-speed mechanism (3) is connected with an output end of the planet carrier (8), an output end of the infinitely-variable-speed mechanism (3) is connected with an input end of the speed reducing mechanism (15), and an output end of the speed reducing mechanism (15) is connected with the output shaft (16). Switching among a hybrid mode, a pure motor driving mode and a pure engine driving mode can be realized by combination or separation of a clutch and a brake.
