Abstract

The invention relates to a transmission for a stroke lengthening hybrid power automobile, which is characterized in that: an electric motor is connected with the transmission via a first left input shaft, an engine is connected with the transmission via a clutch and a first right input shaft; the power of the electric motor is transferred to driving automobile wheels via the first left input shaft, a second left input shaft, a main speed reducer, a differential and a transmission shaft; and the power of the engine is transferred to the driving automobile wheels via the clutch, the first right input shaft, a second right input shaft, the main speed reducer, the differential and the transmission shaft. The transmission with compact structure can adopt only one electric motor to realize the design concept of the stroke lengthening hybrid power automobile, the cost is greatly lowered and the layout and design difficulty of the entire automobile cab is reduced dramatically.

Description

Technical field: [0001] The invention relates to a transmission for a range extender hybrid electric vehicle, which is used for carrying a range extender (Range Extender, RE) hybrid electric vehicle, and belongs to the technical field of hybrid electric vehicle power transmission systems. Background technique: [0002] With the advancement of electric vehicle technology, especially the advancement of battery technology, and the increasingly stringent emission regulations, the expectations of private and government departments for the commercialization of electric vehicles are increasing day by day. However, the high complexity and high cost of strong hybrids, as well as the short driving range and high cost of pure electric vehicles, are always obstacles to the commercialization of electric vehicles. In order to overcome the above obstacles, accelerate the commercialization of electric vehicles, and improve the fuel economy and emissions of the vehicle to the greatest extent...
