The invention relates to a shaft grounding device (E) for establishing an electrically conductive connection between a rotatable shaft (W) and a housing (GH), which shaft grounding device (E) is mechanically and electrically connected to the housing (GH) and has a plurality of flexurally elastic and electrically conductive contact elements (EK) which make an electrically conductive sliding contact (SK) with a circumferential surface (C) of the shaft (W) or of a sleeve mounted on the shaft (W), the contact elements (EK) are arranged and designed in such a way that they bring about a preload of the sliding contact (SK) on the basis of their own flexural elasticity, the shaft grounding device (E) has at least one guide element (EF) which is arranged to avoid bending of the contact elements (EK) when the shaft grounding device (E) is mounted on the shaft (W); and a transmission (G) or an electric axle drive unit (EA) for a motor vehicle having such an axle grounding device (E); and an electric machine (EM2) having such a shaft grounding device (E).
用于在可旋转的轴(W)与壳体(GH)之间建立导电连接的轴接地装置(E),该轴接地装置(E)与所述壳体(GH)机械地和电连接并且具有多个弯曲弹性的且导电的接触元件(EK),这些接触元件与轴(W)的或者安装在该轴(W)上的套筒的圆周面(C)构成导电的滑动接触(SK),所述接触元件(EK)设置和构成为,使得它们基于其自身的弯曲弹性而促成滑动接触(SK)的预紧,所述轴接地装置(E)具有至少一个导向元件(EF),该导向元件设置用于在所述轴接地装置(E)装配到轴(W)上时避免接触元件(EK)折弯;以及用于机动车的具有这样的轴接地装置(E)的变速器(G)或者电动的轴驱动单元(EA);以及具有这样的轴接地装置(E)的电机(EM2)。
