The invention discloses a power-uninterrupted central electric drive system and a vehicle. The power-uninterrupted central electric drive system comprises an output shaft, two transmission assemblies and two driving parts. Each transmission assembly comprises a front shaft, an intermediate shaft, a rear shaft, a front gear shifting transmission and a rear gear shifting transmission, the front gear shifting transmission is connected with the front shaft, the intermediate shaft and the rear shaft, and the rear gear shifting transmission is connected with the rear shaft and the output shaft, so that multiple gear selections exist between the rear shaft and the output shaft; the two driving parts are in driving connection with the two front shafts correspondingly, and each driving part is used for driving the front shaft connected with the driving part to rotate. According to the scheme, non-interruption of gear shifting power and multi-gear switching of different speed ratios can be achieved, and the gear shifting pause feeling in the driving process is reduced. The two transmission assemblies and the two driving parts can be completely interchanged, the universality is good, the cost is low, only one type of equipment and parts need to be arranged during maintenance, the maintenance difficulty and cost are reduced, and the system reliability is high.
本发明公开了一种动力不中断中央电驱系统及车辆,动力不中断中央电驱系统包括输出轴、两组传动总成及两个驱动部;各传动总成包括前轴、中间轴、后轴、前换挡变速器及后换挡变速器,前换挡变速器连接前轴、中间轴及后轴,后换挡变速器连接后轴与输出轴,使得后轴与输出轴之间具有多种挡位选择;两个驱动部分别与两个前轴驱动连接,各驱动部用于驱动其连接的前轴转动。本方案能够实现换挡动力不中断和不同速比的多挡位切换,降低行车过程中的换挡顿挫感。两组传动总成及驱动部可完全互换,通用性好,成本低,且维修时只需要配设一种类型的设备及零件即可,降低维修难度及成本,系统可靠性高。
