The invention discloses an electric drive system integrating a two-gear speed reducer and a speed increaser, relates to the technical field of hybrid electric vehicle drive system structures, and is mainly used for solving the problems that a traditional hybrid electric vehicle adopts a single-gear speed reducer, oil consumption is high during high-speed running, and the highest vehicle speed is low. The main structure is as follows: the system comprises a motor controller, which is connected with a generator, a driving motor and a battery respectively; an engine is in transmission connectionwith the generator through a speed increaser arranged in a reduction gearbox, and the driving motor is in transmission connection with a wheel axle through a two-gear speed reducer arranged in the reduction gearbox. According to the electric driving system integrating the two-gear speed reducer and the speed increaser, the two-gear speed reducer and the single-gear speed increaser are integrally arranged in the speed reduction box, the speed reduction range of the motor can be increased through gear shifting, and the defects that oil consumption is high and the highest vehicle speed is low during high-speed driving are overcome.

    本发明公开了一种集两档减速器和增速器于一体的电驱动系统,涉及混合动力汽车驱动系统结构技术领域,主要用于解决传统的混合动力汽车采用单档减速器,存在高速行驶时油耗高、且最高车速较低的问题。其主要结构为:包括电机控制器,所述电机控制器分别与发电机、驱动电机以及电池连接;所述发动机通过设置在减速箱内的增速器与发电机传动连接,所述驱动电机通过设置在减速箱内的两档减速器与车轮轴传动连接。本发明提供的一种集两档减速器和增速器于一体的电驱动系统,将两档减速器和单档增速器集成设置于减速箱中,能通过换挡,增加电机的减速范围,避免高速行驶时油耗高、且最高车速较低的缺点。
