Abstract

A power-split oil-electric hybrid power system integrated with a flywheel battery, including a primary planetary carrier, which is connected to the output shaft of an internal combustion engine, and the secondary planetary carrier is connected to the final planetary wheel and the final planetary wheel through the first clutch The final internal ring gear is connected to the external fixed end through the second clutch, the secondary internal ring gear is connected to the motor rotor in the flywheel battery unit, the inner side of the motor rotor is the motor stator, and the motor rotor is connected to the flywheel through the magnetic powder clutch; the primary The sun gear, the secondary sun gear and the final sun gear are sequentially installed on the output shaft of the second servo motor, and the final planet carrier in the planetary coupling device is the output port of the power. The present invention has two modes: input split flow and compound split flow , and the flywheel battery is integrated into the power-split hybrid system to ensure that the hybrid system has high transmission efficiency in the full speed ratio range.

Description

technical field [0001] The invention belongs to the technical field of gasoline-electric hybrid power for automobiles, and in particular relates to a power-split type gasoline-electric hybrid power system integrated with a flywheel battery. Background technique [0002] The planetary coupling power split stepless transmission system refers to the transmission device that uses the planetary mechanism to split the power transmitted by the engine into mechanical and electrical paths for transmission, and finally converges to drive the car. The system realizes the decoupling of the engine and the load, which not only ensures that the engine works in a high-efficiency area, but also makes full use of the advantages of mechanical power flow transmission efficiency and high reliability. The planetary coupling power split hybrid power system can be divided into three types: input type, output type and compound type, and the three structures have their own different speed ratio range...
