The invention discloses a high-speed-ratio electric drive axle, and relates to the technical field of automobile parts. Comprising a gearbox, a lubricating oil tank and an oil draining tank, a motor box is arranged on the right side of the gearbox, fixing bolts penetrate through a first connecting ring and a second connecting ring, first elastic pieces are installed on the two sides of the left side of the first connecting ring and the two sides of the left side of the second connecting ring, and abutting blocks are installed on the fixing bolts. The large-speed-ratio electric drive axle is provided with the lubricating oil tank, the electromagnetic valve can be opened regularly through cooperation of the electromagnetic valve and the PLC, lubricating oil in the lubricating oil tank is conveyed to the brush type oil guide head in the gearbox through the connecting pipe, and under the vibration effect of an automobile, the lubricating oil can be conveyed to the brush type oil guide head. The brush type oil guide head is arranged, so that lubricating oil on the brush type oil guide head is more uniformly scattered on parts such as a gear, the lubricating efficiency of the parts such as the gear is improved, the parts such as the gear in a gearbox are lubricated, a worker does not need to enter a vehicle bottom for oiling, and more convenience and labor saving are achieved.

    本发明公开了一种大速比电驱桥,涉及汽车零部件技术领域。包括变速箱、润滑油箱和沥油箱,所述变速箱的右侧设置有电机箱,所述第一连接环和第二连接环上贯穿有固定螺栓,所述第一连接环和第二连接环的左侧两侧均安装有第一弹性片,所述固定螺栓上安装有抵接块。该大速比电驱桥设置有润滑油箱,可通过电磁阀与PLC控制器的配合,定期将电磁阀打开,将润滑油箱内的润滑油通过连接管输送至变速箱内的毛刷式导油头上,在汽车的振动作用下,使毛刷式导油头上的润滑油更加均匀的洒落在齿轮等零部件上,提高了对齿轮等零部件的润滑效率,从而实现对变速箱内的齿轮等零部件进行润滑,无需工作人员进入到车底进行涂油,更加方便省力。
