Abstract

The invention discloses a hybrid power system, comprising an engine, a planetary gear train, a clutch, a main shaft, an electric motor, a power supply assembly for supplying power to the electric motor, a hydraulic pump, a hydraulic motor, a first solenoid valve, a second solenoid valve, a third solenoid valve, an oil tank and an accumulator. The output shaft of the engine is coaxially connected with the ring gear of the planetary gear train, the output shaft of the motor is coaxially connected with the center gear of the planetary gear train, the planet carrier of the planetary gear train iscoaxially connected with the main shaft, and the main shaft is drivingly connected with the first wheel; The rotating shaft of the hydraulic pump is connected with the spindle drive, the hydraulic pump is used for driving the rotating shaft of the hydraulic motor to rotate, and the rotating shaft of the hydraulic motor is connected with the second wheel drive; A third solenoid valve is connected to the accumulator. The invention can control the operation of an engine, an electric motor or a hydraulic motor to realize a plurality of working modes of a hybrid power system and improve the power performance and economy of a vehicle having the hybrid power system.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a hybrid power system and a control method. Background technique [0002] As a fast-paced and efficient means of transportation in life, the number of cars has increased year by year in recent years. However, most traditional cars use fossil fuels (such as gasoline, diesel, etc.) Cause pollution, do not meet the requirements of energy saving and environmental protection. Therefore, it is urgent to use non-polluting new energy sources (such as electric energy) to replace fossil fuels to provide power for automobiles. [0003] The prior art provides a hybrid power system, including: an engine, a clutch, a transmission assembly, and a motor. Among them, the engine and the motor are used as power sources to drive the wheels to rotate, the transmission assembly is used to change the speed of the wheels, and the clutch is connected to the output shaft of the engine. When the clutch is dis...
