The invention discloses a cooling and lubricating structure of an electric shaft driving system, the electric shaft driving system and an automobile, the cooling and lubricating structure of the electric shaft driving system is arranged in the electric shaft driving system which is provided with a motor, a reduction gearbox and a differential mechanism, the motor comprises a hollow motor shaft, a long half shaft penetrates through the motor shaft, engine oil is arranged in the reduction gearbox, and the differential mechanism is arranged in the reduction gearbox. The differential mechanism is provided with a half axle gear, the long half axle is in spline connection with the half axle gear, an oil seal is arranged between the motor shaft far away from one side of the gearbox and the long half axle, and engine oil in the reduction gearbox enters an area between the motor shaft and the long half axle to cool the motor shaft. And entering a spline connection area connecting the long half shaft and the half shaft gear to lubricate the spline connection. The engine oil effectively absorbs heat generated by the motor, the cooling performance of the motor is improved, the spline connection area is lubricated, the abrasion resistance of spline connection is improved, and the service life of spline connection is prolonged.

    本发明公开了一种电轴驱动系统的冷却和润滑结构、电轴驱动系统和汽车,该电轴驱动系统的冷却和润滑结构设置在具有电动机、减速箱和差速器的电轴驱动系统中,电动机包括一空心的电动机轴,一长半轴穿过电动机轴,减速箱内有机油,差速器设有半轴齿轮,长半轴和所述半轴齿轮为花键链接,在远离变速箱一侧的电动机轴和长半轴之间设置油封,减速箱内的机油进入到电动机轴和长半轴之间的区域以冷却电动机轴,以及进入到连接长半轴和半轴齿轮的花键连接区域以润滑花键连接。机油有效地吸收了电机产生的热量,改善了电机的冷却性能,且对花键连接区域进行了润滑而提高了花键连接的耐磨性和使用寿命。
