The invention discloses a hybrid power system and its application, belonging to the field of automobiles. The system includes: an engine, a clutch, a planetary gear train, a first motor, a second motor, a gear assembly, a first brake, and a rechargeable and dischargeable battery. The planetary gear train includes: a first transmission end, a second transmission end, and a third transmission end; the first transmission end of the planetary gear train is sequentially connected with the clutch and the engine through the transmission shaft, and the second transmission end is connected with the first transmission end through the transmission shaft. Motor transmission connection, the third transmission end is fixedly connected with the rotor of the second motor, and is in transmission connection with the gear assembly; the gear assembly is in transmission connection with the wheel through the transmission shaft; the first brake is arranged between the second transmission end and the first motor On the transmission shaft, it is used to control the rotation or braking of the second transmission end, so as to disconnect or connect the power transmission path between the first transmission end and the third transmission end; the battery provides electric energy for the first motor and the second motor, and The first motor and the second motor are connected in parallel.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a hybrid power system and its application. Background technique [0002] Traditional cars rely on burning fossil fuels (such as gasoline, diesel, etc.) to provide power for the engine, and the exhaust gas will pollute the environment, which does not meet the requirements of energy saving and environmental protection. Therefore, it is necessary to replace fossil fuels with non-polluting new energy sources such as electric energy to provide power for automobiles. However, pure electric vehicles powered by electric energy have a short cruising range and incomplete supporting facilities, so it is difficult to be widely used in the short term. Combining fossil fuels and electric energy can not only alleviate the crisis of fossil fuels, but also make up for the defects of pure electric vehicles. Therefore, it is very necessary to provide a hybrid power system that can utilize fossil fuels a...
