The invention provides a power-interruption-free transmission system in the pure electric gear shifting process and a using method. The power-interruption-free transmission system comprises a driving structure, a speed changing structure and an output shaft. The driving structure comprises a first motor and a second motor which are arranged in parallel, the speed changing structure comprises a first gearbox and a second gearbox which are fixedly connected with an output shaft of the first motor and an output shaft of the second motor respectively, and the first gearbox and the second gearbox are arranged on the output shafts in a sleeving mode. By adopting the driving structure composed of the two motors arranged in parallel and the two gearboxes connected with the two motors respectively, no power interruption is achieved through power coupling, the safety of the whole vehicle in the driving process is guaranteed, the gear shifting comfort is effectively improved, and the service life of the whole vehicle is prolonged. The technical problem that power interruption exists in the gear shifting process of a conventional multi-gear electric drive system is solved.

    本发明给出了一种纯电动换挡过程无动力中断的传动系统及使用方法,包括驱动结构、变速结构和输出轴;所述驱动结构包括并联设置的一号电机和二号电机,所述变速结构包括分别与一号电机的输出轴和二号电机的输出轴固定连接的一号变速箱和与二号变速箱,所述一号变速箱和二号变速箱均套设在输出轴上,通过采用并联设置的两台电机组成的驱动结构和分别与两台电机连接的两台变速箱,通过动力的耦合实现无动力中断,保证了整车在驾驶途中的安全性,并且有效提升换挡舒适性,解决了常规多档电驱系统在换挡过程中存在动力中断的技术问题。
