Abstract

The invention discloses a hybrid power driving system. The system comprises an internal combustion engine, a brushless double-electromechanical-port motor and a wheel driving shaft; the internal combustion engine is connected with a first mechanical port of the brushless double-electromechanical-port motor through an output shaft; the wheel driving shaft is connected with a second mechanical portof the brushless double-electromechanical-port motor; the internal combustion engine provides heat energy for the hybrid power driving system; the brushless double-electromechanical-port motor is usedfor providing electric driving when serving as a motor and, used for braking energy recovery when serving as a power generator, and used for power distribution of the internal combustion engine and the motor when serving as a transmission; the wheel driving shaft is used for converting electric energy transmitted by the brushless double-electromechanical-port motor into mechanical energy. The brushless double-electromechanical-port motor is adopted to replace a planetary gearbox, the power generator and the motor of a traditional driving system, so that mechanical abrasion is effectively reduced; meanwhile, the structure is more compact, and the practicability is higher.

Description

technical field [0001] The invention belongs to the field of drive systems, and more specifically relates to a hybrid drive system. Background technique [0002] As the protection of the atmospheric environment and the saving of fuel energy become more and more important, the hybrid electric vehicle driven by the combination of the internal combustion engine and the electric motor becomes an important development direction. In hybrid electric vehicles, in order to realize the drive of various combinations of internal combustion engine and electric motor, the power distribution device with variable speed and torque transmission ratio becomes particularly critical. [0003] Existing automotive hybrid drive systems, represented by Toyota Prius, mostly use planetary gears to decouple the speed between the internal combustion engine and the wheel load; at the same time, an additional motor / generator torque regulation is required to complete the load between the internal combustio...
