Abstract

The invention relates to new energy automobile parts, in particular to a dual-motor hybrid power automatic transmission. According to the dual-motor hybrid power automatic transmission, a dual-input-shaft structure is adopted, the two dual input shafts are parallel to an output shaft, and the first input shaft can transmit the power of a first motor as well as the power of an engine by being connected with the engine through a clutch; the second input shaft can transmit the power of a second motor; meanwhile, the power of the engine can also be separated from the first input shaft through the clutch, the power of the first motor can also be separated from the first input shaft through a second gear and fourth gear synchronizer, and the power of the second motor can also be separated from the second input shaft through a first and third synchronizer. By the adoption of the dual-motor hybrid power automatic transmission, all driving states of starting and stopping of the engine, the pure electric mode, the series mode, the parallel mode and the parallel-serial mode can be realized, unpowered interruption type automatic gear shafting of each power source can also be achieved, and therefore driving comfort is guaranteed.

Description

technical field [0001] The invention relates to new energy automobile parts, in particular to a dual-motor hybrid automatic transmission. Background technique [0002] New energy vehicles are rapidly developing in the industry due to their energy saving and environmental protection features. This type of vehicle will definitely change the existing energy structure. As an important branch of new energy vehicles, hybrid electric vehicles give full play to the advantages of electric motors on the basis of retaining traditional engines, and greatly improve vehicle fuel economy and emissions. Hybrid electric vehicles have price advantages and endurance advantages that pure electric vehicles do not have, so the development and promotion of hybrid power systems is imperative. As one of the key technologies of the hybrid power system, the power coupling system has been researched all the time, but there are few breakthroughs in domestic research lacking the technical foundation of ...
