Abstract

The invention relates to a hybrid vehicle and its planetary row hybrid power system. The planetary row hybrid power system includes an engine, a planetary row, a main drive motor, an auxiliary motor and a system output shaft. The planetary row has a first transmission component, one of which is The second transmission part, one is the third transmission part, the main drive motor is connected with the first transmission part, the engine is connected with the second transmission part, the auxiliary motor is connected with the third transmission part, and the third transmission part is provided with a first Brake, the second transmission component is provided with a second brake, and the second brake locks the second transmission component when the hybrid power system is in the pure electric driving mode. When the power provided by the main drive motor is less than the required power of the vehicle, the second transmission part is locked by the second brake, the auxiliary motor drives the third transmission part to rotate and drives the planetary wheel to rotate, and the auxiliary motor provides a certain compensation power to realize the complete vehicle. The continuation of power is maintained, and the speed-up performance of the whole vehicle is better.

Description

technical field [0001] The invention relates to a hybrid power vehicle and a planetary row hybrid power system thereof. Background technique [0002] The current hybrid power system mainly uses a planetary mechanism as a power splitting device. The advantage of the planetary row system is that it can realize the decoupling between the engine speed and the output shaft speed. The control system can control the speed and torque of the engine at any speed, so as to realize the high efficiency of the engine. [0003] For example, a Chinese patent document with the authorized announcement number CN207345474U discloses a hybrid vehicle and its three-axis planetary hybrid system, which includes an engine, a planetary row, a first motor, a second motor and a system output shaft, and the planetary row Including the ring gear, the sun gear, the planet carrier and the planet gear, wherein the engine is connected with the planet carrier, the second motor is connected with the ring gear...
