The electric four-wheel drive system comprises a gear shifting assembly, a walking electric drive assembly, a front axle assembly, a rear axle assembly and a clutch, the gear shifting assembly is provided with a power input end and a power output end, and the walking electric drive assembly is in transmission connection with the power input end of the gear shifting assembly; the power output end of the gear shifting assembly is in transmission connection with the rear axle assembly, and the power output end of the gear shifting assembly is further in transmission connection with the front axle assembly through the clutch, so that the walking electric drive assembly can directly provide power for the gear shifting assembly, and the gear shifting assembly can respectively provide power for the front axle assembly and the rear axle assembly. And the clutch is arranged between the gear shifting assembly and the front axle assembly, so that the power input of the front axle assembly can be switched through the clutch, and the electric four-wheel drive system can be switched into a four-wheel drive mode or a rear drive mode.

    本发明公开了一种电动四驱系统及拖拉机,包括换挡总成、行走电驱动总成、前桥总成、后桥总成和离合器,所述换挡总成具有动力输入端和动力输出端,所述行走电驱动总成与所述换挡总成的动力输入端传动连接,所述换挡总成的动力输出端与所述后桥总成传动连接,所述换挡总成的动力输出端还通过所述离合器与所述前桥总成传动连接,如此可直接由行走电驱动总成对换挡总成提供动力,并由换挡总成对前桥总成和后桥总成分别提供动力,而换挡总成与前桥总成之间设置离合器,这样可通过离合器对前桥总成的动力输入进行切换,即使得该电动四驱系统可切换为四驱模式或是后驱模式。
