The invention relates to the technical field of electric drive structures, in particular to an oil cooling electric drive assembly and an automobile. Comprising a main shell, a speed reducer shell, a booster cavity, an oil return cavity and an oil cooler, and a driving motor is arranged in the main shell; the speed reducer shell is arranged in the main shell, and a speed reducer input shaft which is coaxial with the rotating shaft and connected to the end of the rotating shaft is arranged in the speed reducer shell. The pressurizing cavity is a closed cavity arranged on the speed reducer shell, and an impeller which is fixedly connected with the end part of the input shaft of the speed reducer and rotates along with the input shaft of the speed reducer is arranged in the pressurizing cavity; the oil return cavity is formed in the bottommost part of the main shell; the oil cooler is arranged in the main shell; the oil return cavity, the pressurizing cavity, the oil cooler and the rotor oil inlet structure are connected in series into a whole through oil way structures in the main shell and the speed reducer shell in the oil flowing direction. The electric drive assembly is simple in structure, oil liquid flowing can be achieved through rotation of the rotating shaft without additionally arranging an oil pump, the oil liquid cooling and lubricating effect is extremely good, and the manufacturing cost is low.

    本发明涉及电驱动结构技术领域,具体地指一种油冷电驱动总成及汽车。包括主壳体、减速器壳体、增压腔、回油腔和油冷器,主壳体内设置有驱动电机;减速器壳体设置于主壳体内,减速器壳体内设置有与转轴同轴布置且连接于转轴端部的减速器输入轴;增压腔是设置于减速器壳体上的密闭腔体,增压腔内安装有与减速器输入轴端部固定连接并跟随减速器输入轴旋转的叶轮;回油腔设置于主壳体的最底部;油冷器设置于主壳体内;回油腔、增压腔、油冷器和转子进油结构按照油液流动方向通过主壳体和减速器壳体内的油路结构串联为一体。本申请的电驱动总成结构简单,无需增设油泵即可利用转轴旋转实现油液的流动,油液冷却润滑的效果极好,制造成本低。
