Embodiment 1

[0032] The embodiment of the present invention provides a hybrid power transmission system, which can solve the technical problem that functions such as shifting torque compensation, starting the engine by the motor, and using the gear of the gearbox by the motor cannot be simultaneously performed.

[0033] figure 1 It is a hybrid transmission system, including: engine output shaft 1, gearbox input shaft 2, gearbox input shaft gear 3, first synchronizer 4, gear gear train 5, gearbox output shaft 6, shift synchronizer 7. Transmission output shaft gear 8, motor output shaft 9, motor output shaft gear 10, intermediate shaft first gear 11, intermediate shaft 12, second synchronizer 13, and intermediate shaft second gear 14.

[0034] The engine output shaft 1 is connected to the gearbox input shaft 2, the gearbox input shaft gear 3 is sleeved on the gearbox input shaft 2, and the first synchronizer 4 is used to engage the gearbox input shaft 2 with the gearbox input shaft gear 3 or...

Embodiment 2

[0043] On the basis of Embodiment 1, as a preferred embodiment: the gear train 5 includes: four driving gears 51 and four driven gears 52 . Four gear driving gears 51, which are connected with the gearbox input shaft 2; four gear driven gears 52, which are sleeved on the gearbox output shaft 6, and the gear driven gears 52 and the gear driving gear 51 One-to-one meshing; the shift synchronizer 7 is a double-sided synchronizer, which is used to engage or separate the four gear driven gears 52 from the transmission output shaft 6 . It should be noted that, in the embodiment of the present invention, the number of gear driving gears 51 , gear driven gears 52 and shift synchronizers 7 can be appropriately increased to meet more speed requirements.

Embodiment 3

[0045] On the basis of Example 1, as a preferred implementation mode: both the transmission output shaft gear 8 and the second countershaft gear 14 mesh with the differential gear 15 to drive the wheels to rotate, the structure is simple, and the performance is stable and reliable.

Abstract

The invention discloses a hybrid power speed change system, a using method and a hybrid power automobile, and relates to the technical field of hybrid power. The system comprises the components of: anengine output shaft, a gearbox input shaft, a gearbox input shaft gear, a first synchronizer, a gear gear train, a gearbox output shaft, a gear shifting synchronizer, a gearbox output shaft gear, a motor output shaft, a motor output shaft gear, an intermediate shaft first gear, an intermediate shaft, a second synchronizer and an intermediate shaft second gear. The first synchronizer is used for connecting or disconnecting the gearbox input shaft with the gearbox input shaft gear; the gear shifting synchronizer is used for connecting or disconnecting the gear train and the gearbox output shaft; the second synchronizer is used for connecting or disconnecting the intermediate shaft first gear and the intermediate shaft. The technical problem that functions of gear shifting torque compensation, engine stopping and starting, gear utilization of a gearbox by a motor and the like cannot be achieved at the same time in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of hybrid power technology, in particular to a hybrid power transmission system, a use method and a hybrid power vehicle. Background technique [0002] At present, pure electric vehicles are restricted by cruising range and charging facilities, and the marketization process is seriously hindered. Hybrid electric vehicles have many advantages such as convenient refueling, energy saving and environmental protection, and long cruising range. Hybrid electric vehicles will become the trend of future development before the major revolution of power batteries. [0003] In related technologies, there are currently two concentrated technical solutions for single-motor hybrid power: the first P2 solution, that is, the motor is arranged in the middle of the engine and the gearbox, and the driving force of the motor acts on the transmission input shaft, and the speed can be realized through the transmission. ratio change. Since...
