The invention relates to an electric drive axle single planet wheel type two-gear speed reducer structure, and relates to the field of speed reducers. The output shaft is coaxial with the center shaft C and is in transmission with the center shaft C, the two middle shafts B are arranged on the two sides of the center shaft C in parallel, the two input shafts A are arranged on the outer sides, away from each other, of the two middle shafts B in parallel, and the two motors are correspondingly connected with the two input shafts A respectively. The input shaft A is provided with a first gear, and the center shaft C is sleeved with a fourth gear capable of being in transmission with the first gear. The middle shaft B is provided with a sixth gear and a seventh gear, and the center shaft C is provided with a fifth gear meshed with the sixth gear, an eighth gear meshed with the seventh gear and a gear shifting dog tooth T which is connected with the fourth gear and can be connected with the fifth gear or the eighth gear. Power transmission between the double motors and the differential mechanism can be completed, the torque increasing and speed reducing functions are achieved, and the electric drive axle can be carried to be widely applied to heavy truck models.

    本发明涉及一种电驱桥单行星轮式两档减速器结构,涉及减速器的领域,其包括中心轴C、与中心轴C同轴线并传动的输出轴、两个平行设于中心轴C两侧的中间轴B、两个平行设于两个中间轴B相背离外侧的输入轴A、以及两个分别对应与两个输入轴A连接的电机;输入轴A设有第一齿轮,中心轴C套有可与第一齿轮传动的第四齿轮;中间轴B设有第六齿轮和第七齿轮,中心轴C设有与第六齿轮啮合的第五齿轮、与第七齿轮啮合的第八齿轮、以及与第四齿轮连接并可与第五齿轮或第八齿轮连接的换档狗齿T。本发明可以完成双电机至差速器间的动力传递,并实现增扭降速功能,可搭载电驱桥在重卡车型上广泛应用。
