Wheel hub motor with potential equalization

摘要

A wheel hub motor for driving a motor vehicle is provided. Aging of the rolling element bearings used to support the rotor is prevented, while at the same time minimizing the emission of electromagnetic waves, in that the wheel hub motor includes a—rotor,—a hub (1), —a wheel bearing having a first bearing ring (2) which is non-rotatably and electrically conductively connected to the hub (1), and a second bearing ring (3) which is non-rotatably and electrically conductively connected to the rotor, and—a contact element (4) for creating an electrically conductive connection between said bearing rings (2, 3), the contact element (4) being supported against the hub (1) via a spring (6) and has a pressure contact with a potential equalization element (5) that is non-rotatably and electrically conductively connected to the second bearing ring (3).
