The invention relates to a differential type hybrid power transmission structure which comprises an engine, a motor, a first shaft, a first differential, a second shaft and a third shaft. The output end of the engine is connected with a first shaft, and a first gear is fixed to the first shaft. The first differential mechanism comprises a first differential mechanism shell, a first half axle gear, a second half axle gear and a first planetary gear shaft, the first planetary gear shaft is fixed in the first differential mechanism shell, a first planetary gear is sleeved on the first planetary gear shaft in an empty mode, and the first half axle gear and the second half axle gear are both meshed with the first planetary gear. A first main reduction gear meshed with the first gear is fixed to the first differential mechanism shell. The power output end of the motor is connected with a second shaft, the second shaft is fixedly connected with the second half axle gear, a third shaft is fixedly connected with the first half axle gear, and a second gear is fixed to the third shaft. By means of the multi-degree of freedom of the differential mechanism, common input of the engine and the motor is achieved, and a new hybrid power transmission structure is formed.
Description
technical field [0001] The invention relates to auto parts, in particular to a differential type hybrid transmission structure. Background technique [0002] Hybrid technology can reduce fuel consumption and emissions, which is in line with the national guidelines for low carbonization, and fuel economy has always been the most important indicator for consumers, affecting one of the lifeblood of automobile companies. The current hybrid transmissions on the market mainly use planetary gears Or double motor structure, no more new form structure. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a differential type hybrid transmission structure, which adopts a new structure. [0004] A differential type hybrid transmission structure according to the present invention includes an engine, a motor, a first shaft, a first differential, a second shaft and a third shaft; the output end of the engine is connected to the first shaft. shafts are co...
