Abstract

The invention discloses a hybrid power drive system. The hybrid power drive system comprises a first planetary gear train, a second planetary gear train, an engine, a first electric motor generator, a second electric motor generator, a first brake, a second brake, a third brake, a front axle, and a rear axle. The first planetary gear train comprises a first sun gear, a first planet gear, a first planet carrier, and a first gear ring. The second planetary gear train comprises a second sun gear, a second planet gear, a second planet carrier, and a second gear ring. The first gear ring and the second sun gear are connected and rotate synchronously. A clutch is arranged between the engine and the first sun gear. The first electric motor generator and the first planet carrier are connected. The second electric motor generator and the second gear ring are connected. The first brake is used to brake the first planet carrier. The second brake is used to brake the first gear ring. The third brake is used to brake the second gear ring. A power transmission shaft with the clutch is arranged between the front axle and the rear axle. The hybrid power drive system is simple in structure and reliable in transmission.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid drive system. Background technique [0002] In related technologies, most of the hybrid drive and Zengcheng electric vehicles need to adjust the output torque and speed by controlling the electromagnetic torque generated by the two motors during power transmission, which causes the secondary conversion of energy, resulting in low efficiency of electric vehicles . [0003] Secondly, the power system of hybrid drive and Zeng electric vehicle has complex structure, huge system and high cost. In addition, in traditional multi-speed transmissions, most of the gears are selected through the shift fork sleeve when the clutch cuts off the power. There are many pairs of gears, which take up a lot of space and have a complicated structure. [0004] Moreover, some hybrid models have only one motor. When switching from pure electric to hybrid mode, the drive motor is generally us...
