Hybrid power transmission and hybrid power driving system

Abstract

The invention discloses a hybrid power transmission and a hybrid power driving system. The hybrid power transmission comprises a first input shaft, a second input shaft, an output shaft, a coupling gear pair, a first gear shifting gear pair and a second gear shifting gear pair, wherein the coupling gear pair is arranged between the first input shaft and the second input shaft, the coupling gear pair is used for coupling the power of the first input shaft and the power of the second input shaft and transmitting the power to the output shaft, the first gear shifting gear pair and the second gearshifting gear pair are located on the two sides of the coupling gear pair correspondingly, a second clutch enabling the output shaft to be in transmission connection with or separated from the firstinput shaft is arranged on the first gear shifting gear pair, and a third clutch enabling the output shaft to be in transmission connection with or separated from the second input shaft is arranged onthe second gear shifting gear pair. The hybrid power driving system comprises a battery pack, a first inverter, a second inverter, a first power source, a second power source, a differential mechanism and the hybrid power transmission. According to the hybrid power transmission and the hybrid power driving system, the fuel consumption can be reduced, and the electric energy utilization rate can be improved.

Description

technical field [0001] The invention relates to the field of hybrid vehicle manufacturing, in particular to a hybrid transmission and a hybrid drive system. Background technique [0002] Different from traditional pure fuel vehicles, hybrid vehicles make comprehensive use of multiple power sources, that is, use multiple powers as the power input of the transmission, and then output them into different drive modes through the transmission, such as pure fuel drive, pure electric drive, hybrid drive etc. However, most of the hybrid transmissions used in existing hybrid vehicles are slightly improved on the basis of traditional transmissions. While utilizing multiple power sources to achieve different gear output, they cannot make the internal combustion engine better. Operates in the low fuel consumption area, or cannot make the electric motor work in the high efficiency area. In addition, the existing hybrid transmissions are complex in transmission and generate relatively l...

However, most of the hybrid transmissions used in existing hybrid vehicles are slightly improved on the basis of traditional transmissions. While utilizing multiple power sources to achieve different gear output, they cannot make the internal combustion engine better. Running in the low fuel consumption area, or failing to make the motor work in the high efficiency area

In addition, the existing hybrid transmissions are complex in transmission and generate relatively large noises, and some even have power interruptions when the working conditions are switched, resulting in dissatisfaction among users
