The invention relates to a bidirectional electric control overrunning clutch type permanent magnet two-gear transmission and a gear shifting method thereof. A clutch comprises a transmission shell, a driving mechanism, a magnetic field modulation gear speed change mechanism, a speed change mechanism connecting piece, an electric control overrunning clutch and a clutch. A magnetic field modulation gear serves as a variable transmission mechanism, and gear shifting impact and reducer noise are reduced; a double-output-shaft structural form is adopted, the output low-speed shaft is connected with the electric control overrun clutch, the clutch is connected with the output high-speed shaft, when the clutch is connected, the electric control overrun clutch automatically overruns, gear shifting without power interruption is achieved, and the running stability of a vehicle is improved; meanwhile, the bidirectional overrunning function is achieved through a bidirectional controllable pawl in the electric control overrunning clutch, on the premise that the structure is compact, four stations of two forward gears, a reverse gear and a neutral gear are achieved, the gear shifting method is simple, and control is convenient.

    本发明涉及一种双向电控超越离合式永磁两挡变速器及其换挡方法,该离合器包括变速器壳体、驱动机构、磁场调制齿轮变速机构、变速机机构连接件、电控超越离合器和离合器。通过磁场调制齿轮作为变速传动机构,降低了换挡冲击与减速器噪声;采用双输出轴的结构形式,输出低速轴和电控超越离合器连接,离合器与输出高速轴相连接,离合器接合时,电控超越离合器自动超越实现了无动力中断换挡,提升了车辆行驶平稳性;同时,通过电控超越离合器内部双向可控棘爪实现双向可超越功能,在结构紧凑的前提下,实现了前进两挡,倒挡和空挡四个工位,换挡方法简单,便于控制。
