Problems solved by technology

[0003] Although the current hybrid transmission systems have achieved the above driving modes, and achieved the purpose of energy saving and emission reduction by switching the corresponding working modes according to different working conditions, the current systems have certain technical limitations, such as the announcement number CN101574922B The patent document described a hybrid transmission composed of a motor, a clutch and an AT transmission. On the shaft, when the simultaneous working torque of the engine and the motor exceeds the torque of the AT transmission, it is necessary to limit the power of the motor or engine, or the AT transmission needs to be redevelope...

Abstract

The invention discloses a hybrid-power stepless speed changing system, which comprises an output shaft, a motor power coupling mechanism, a stepless speed changing mechanism and an input shaft. The input shaft is connected with an engine and used for transmitting power to the stepless speed changing mechanism. The motor power coupling mechanism comprises a motor stator, a motor rotor and a motor supporting shaft connected with the motor rotor and further comprises a synchronizer used for realizing power transmission between the input shaft and a motor supporting shaft and/or power transmissionbetween the motor supporting shaft and the output shaft. The hybrid-power stepless speed changing system has advantages that by arrangement of the synchronizer, operation under a pure engine drive mode can still be realized when high-voltage electricity exhausting or high-voltage power system protection occurs, and accordingly an application range of the hybrid power technique is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular, the invention relates to a hybrid continuously variable transmission system. Background technique [0002] A typical hybrid transmission includes an electric motor, a power coupling mechanism and a transmission. The transmission uses a traditional multi-speed AT transmission, a DCT transmission, etc. to realize the speed change. The power generated by the internal combustion engine or the electric motor is transmitted to the transmission respectively, and the power is output to the wheels through the transmission, and the internal combustion engine and the electric motor can output power to the transmission independently or simultaneously. Generally, the hybrid power system has a pure internal combustion engine drive mode, a pure electric motor drive mode, and a simultaneous drive mode of the internal combustion engine and the electric motor. At the same time, the above mod...
