Abstract
A conductor provides electrical connection passing through a rubber cushioned rail vehicle wheel having rubber elements in between a central metal wheel portion and an outer flanged metal wheel tire. Thus, a length of wire has a central conductor connection tag attached to the central wheel portion with U-shaped spring clips at each end straddling over and electrically connecting with an internal mating ridge on the tire extending between two spaced rubber elements separating the central portion and tire.
Claims4
A device for providing electrical connection through a rubber-cushioned rail vehicle wheel, comprising a central wheel part, a wheel tire with a circumferential ridge facing the central wheel part and two neighboring circumferential rubber elements alongside the circumferential ridge between said central part and tire, characterized in that a conducting wire extends generally circumferentially in an internal free space between the neighbouring rubber elements and is connected on the one hand to the central part, and on the other hand to the wheel tire by means of a generally horse-shoe-shaped spring clip, attached to the wire and resiliently held on to the circumferential ridge between said rubber elements.
