Abstract

The invention discloses an oil-electricity hybrid power system and an engineering vehicle. The oil-electricity hybrid power system comprises a power transmission control system, an engine, a motor, an inverter and an energy storage device. The power transmission control system is connected with the engine and the motor, the engine is connected with the motor, and the motor is connected with the energy storage device through the inverter; when a finished automobile is in need of large power, the power transmission control system controls the engine and the motor to work at the same time, and power is output; when the finished automobile is in need of extremely small power or brakes, the power transmission control system controls the engine to work and meanwhile controls the motor to absorb power and stores the power in a battery pack. The oil-electricity hybrid power system and the engineering vehicle have the advantages that energy is saved, emission is reduced, the reliability of the engine is improved, the service life of the engine is prolonged, and the applicable ability of the finished automobile is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an oil-electric hybrid power system and an engineering vehicle including the oil-electric hybrid power system. Background technique [0002] The gasoline-electric hybrid system is mainly composed of control system, drive system, auxiliary system and battery pack. The patent number is CN201220590198, and the name is "Oil-Electric Hybrid Vehicle" in China, which discloses a gasoline-electric hybrid vehicle. , the automotive electrical appliances are equipped with a battery and a controller. The input shaft of the generator is equipped with a runner, and the outer edge of the runner forms a contact connection with the wheel; the controller controls the operation of the engine, inverter and motor, and the generator, transformer, rectifier circuit The charging circuit is formed with the storage battery, and the electric drive circuit is formed by the storage battery, the inverter...
