The invention relates to a transmission and an operation method thereof. The transmission comprises a first power input shaft, a second power input shaft, an output shaft and double clutch, wherein the first power input shaft is used for receiving power from a first power source; the second power input shaft is used for receiving power from a second power source; the output shaft is used for outputting power to wheels, and the output shaft can respectively or simultaneously receive power from the first power source and the second power source; and the double clutch are arranged on the second power input shaft, and at least two gears exist between the second power input shaft and the output shaft. The engine can run in a high-efficiency area for a long time; by adopting the clutch structure of the double clutch, sliding friction control is conducted through the clutches in the gear shifting process, power interruption in the gear shifting process can be avoided, and the driving experience is improved; a double-clutch module structure is adopted, so that the axial size can be shortened; and two-gear arrangement is achieved in the mode that three shafts are sleeved in an empty mode, the axial size can be shortened, and arrangement of the transmission on a vehicle is facilitated.
本发明涉及一种变速器及其运行方法,变速器包括第一动力输入轴,用于接收来自第一动力源的动力;第二动力输入轴,用于接收来自第二动力源的动力;输出轴,用于将动力输出至车轮,并且所述输出轴能够分别或者同时接收来自第一动力源、第二动力源的动力;双离合器,设置在所述第二动力输入轴上,并且在所述第二动力输入轴与所述输出轴之间存在至少两个挡位。本发明使得发动机可长时间在高效区运行;通过采用双离合器的离合器结构,换挡过程中通过离合器滑摩控制,可实现换挡过程中无动力中断,提升驾驶体验;采用双离合器模块结构,可缩短轴向尺寸;用三根轴空套形式实现两档的布置,能够缩短轴向尺寸,方便变速器在车辆上的布置。
