Abstract
The transmission of an electric signal between a driving wheel and the vehicle exclusively by electric conduction requires the presence of two electrically conductive paths. One of the conductive paths includes suspended stationary elements and a bearing of the driving wheel. The end of the transmission is insulated from the ground and the part of the transmission not insulated from the ground is included in the other of the conductive paths.
