The invention relates to the technical field of hybrid power gearboxes, in particular to a front-wheel driving single-motor hybrid power gearbox and a hydraulic cooling and lubricating system, which are constructed on the basis that a vehicle is provided with a rear-wheel pure electric driving system. The system comprises two power sources, namely a generator and an engine, a gear transmission system and a clutch system for transmitting power of the two power sources, and a hydraulic system and a cooling and lubricating system for assisting the generator, the gear transmission system and the clutch system to work, a clutch system is composed of two clutches, opening and closing control of the first clutch determines separation and connection of engine power, and opening and closing control of the second clutch determines whether power of two power sources participates in vehicle driving or not. A rear wheel pure electric driving system is matched, four-wheel pure electric driving and four-wheel hybrid driving are achieved, and the dynamic property and off-road performance of the vehicle are improved; according to the modular design scheme, the same-platform development of multiple types of hybrid power gearboxes with different functions is realized.
