Problems solved by technology

[0002] The current driving device of hybrid electric vehicle, especially the driving device of hybrid electric bus, mainly has two structures. One is that the internal combustion engine is connected to the clutch, the clutch is connected to the motor, and the motor is connected to the drive axle. This structure has poor driving performance and the actual energy saving effect is very poor. The other is that the internal combustion engine is connected to the clutch, the clutch is connected to the motor, the motor is connected to the transmission, and the transmission is connected to the drive axle. This overall structure has good driving performance and good energy-saving effect
[0003] At present, in a hybrid drive device with a transmission, the internal combustion engine and the electric motor are connected in series, and the power is output to the transmission in a single way. And it is mainly controlled by two shift motors, and the two shift motors must work together precisely, which makes the shift control complicated and increases the cost of the vehicle

Abstract

The invention discloses a double-way input hybrid power transmission. The double-way input hybrid power transmission comprises a middle shaft (10), a middle shaft first-gear gear (20), a middle shaft second-gear gear (30), a middle shaft gear (40), a transmission shell (50), an output shaft (60), an output shaft first-gear gear (70), a gear shifting device (80) and an output shaft second-gear gear (90). The middle shaft gear (40) is used for being connected with a motor output gear. An input end (61) and an output end (62) are arranged on the output shaft (60), the input end (61) is used for being connected with a rotating shaft of an internal combustion engine, and the output end (62) is used for outputting the hybrid power of a motor and the internal combustion engine. Compared with single-way input in the prior art, double-way input is achieved, and the double-way input hybrid power transmission is mainly applicable to the field of driving devices of hybrid power automobiles and particularly to the field of driving devices of hybrid power passenger cars.

Description

technical field [0001] The invention relates to the field of transmissions for hybrid electric vehicles, in particular to a dual-input hybrid transmission. Background technique [0002] The current driving device of hybrid electric vehicle, especially the driving device of hybrid electric bus, mainly has two structures. One is that the internal combustion engine is connected to the clutch, the clutch is connected to the motor, and the motor is connected to the drive axle. This structure has poor driving performance and the actual energy saving effect is very poor. The other is that the internal combustion engine is connected to the clutch, the clutch is connected to the motor, the motor is connected to the speed changer, and the speed changer is connected to the drive axle. This overall structure has good driving performance and the actual energy-saving effect is also better. [0003] At present, in a hybrid drive device with a transmission, the internal combustion engine an...
