Abstract

The invention discloses a hybrid power transmission device which is characterized in that a first synchronizing device is fixed with a first input shaft, and the first synchronizing device is selectively matched with a second gear of the input shaft so as to connect or cut off power transmission from an engine to an output gear; the hybrid power transmission device further comprises a third power assembly, the third power assembly comprises a second driving motor, a third input shaft, a third gear and a third synchronizer, the second driving motor is matched with the third input shaft, the third gear and the output gear are rotationally arranged on the third input shaft, and the third gear is meshed with the first gear of the input shaft. The third synchronizer is fixed with the third input shaft; the third synchronizer selectively cooperates with an output gear to connect or disconnect power transmission from the second drive motor to the output gear. According to the invention, power from a plurality of power sources is efficiently transmitted to an output shaft, and fuel efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a hybrid power transmission device. Background technique [0002] 1. Hybrid power devices can be divided into series, parallel, series-parallel hybrid and so on. Here, a series-type hybrid device refers to a hybrid system that includes an engine and a motor, but in which the engine only generates electric power and supplies the electric power to the electric motor and the battery, and the force for driving the wheel-driven vehicle is provided only by the electric motor, and the parallel connection Both the engine and the electric motor of the type hybrid power plant can provide the required force for driving the wheels; [0003] 2. Hybrid power transmission technology is an important means of energy saving and emission reduction for passenger vehicles, and major automobile manufacturers are actively developing it. The series hybrid system can ensure that the en...
