The invention discloses a differential lubricating system, an electric drive assembly and a vehicle, and relates to the technical field of vehicles, the differential lubricating system comprises a speed reducer shell, at least one half shaft and at least one lubricating structure, at least one mounting hole is formed in the speed reducer shell, and the half shaft is rotatably mounted in the corresponding mounting hole; one end of each half shaft is used for being connected with an output gear of a differential mechanism assembly installed in the speed reducer shell, each lubricating structure comprises an oil inlet channel formed in the speed reducer shell and an oil outlet channel formed in the corresponding half shaft, one end of each oil inlet channel communicates with the corresponding installation hole, and the other end of each oil inlet channel communicates with an oil supply structure. One end of the oil outlet channel communicates with the mounting hole so as to correspond to one end of the oil inlet channel in the rotating stroke of the half shaft relative to the speed reducer shell. In the technical scheme of the embodiment of the invention, lubrication can be realized without immersing each gear of the differential assembly into lubricating oil with a relatively high oil level, so that the oil stirring loss of the electric driving system is reduced.

    本发明公开了一种差速器润滑系统、电驱动总成以及车辆,涉及车辆技术领域,其中,差速器润滑系统包括减速器壳体、至少一半轴以及至少一润滑结构,减速器壳体上设置有至少一安装孔,半轴转动安装于对应安装孔,半轴的一端用于与安装于减速器壳体内的差速器总成的输出齿轮连接,润滑结构包括设置在减速器壳体上的进油通道,以及设置在对应半轴上的出油通道,进油通道的一端与安装孔连通,另一端用于与供油结构连通,出油通道的一端与安装孔连通,以在半轴相对减速器壳体的转动行程内,能够与进油通道的一端对应。本发明实施例的技术方案中,无需将差速器总成的各齿轮浸入较高油位的润滑油中也能够实现润滑,降低了电驱动系统的搅油损失。
