The invention relates to a device for grounding a component, comprising a grounding hub (19), which is electrically conductively connected to the ground and is electrically conductively connected to the component at a first axial end. The grounding hub forms an axially extending supply line (28) which opens on a first axial end, along which a lubricant and/or coolant can be guided in a first path to the first axial end. The ground hub is radially inward of the shaft. The grounding hub is provided with a recess (35) connecting the supply line to the intermediate space, which extends in the axial direction as far as the first axial end. A circumferential stop edge (38) is formed on the inner diameter of the shaft and axially on the side of the recess facing away from the first end, whereby a second path is formed for guiding lubricant and/or coolant from the supply line via the recess to the first axial end. The invention also relates to a transmission, an electric axle drive unit for a motor vehicle, and an electric machine, in which the device is implemented.

    本发明涉及一种用于将组件接地的装置,其包括接地毂部(19),接地毂部与地导电连接并且在第一轴向端部上与组件导电连接。接地毂部构成轴向延伸的供应管路(28),其在第一轴向端部上通入,润滑剂和/或冷却剂能够沿着供应管路在第一路径中引导至第一轴向端部。接地毂部处于轴的径向内部。接地毂部设有凹部(35),其将供应管路与中间空间连接,中间空间在轴向上延伸直至第一轴向端部。在轴的内直径上并且在轴向上在凹部的背离第一端部的一侧上构成环绕的滞止边缘(38),借此构成第二路径,用于将润滑剂和/或冷却剂从供应管路经由凹部引导到第一轴向端部。本发明还涉及变速器、用于机动车的电的车桥驱动单元和电机,在它们中实现所述装置。
