Al menos en la zona (3) en la que el elemento de contacto (14) del puente de corriente (8) asignado a la parte interior de la rueda (2) se encuentra con su superficie de contacto (24) contra la parte interior de la rueda (2) , la parte interior de la rueda (2) se compone de un material metálico ligero. Para evitar en una rueda de raíl (1) de este tipo por medios sencillos el riesgo de corrosión por contacto que se produce en un punto de contacto en el que un elemento de contacto del puente de corriente se apoya contra una parte de la parte interior de la rueda que consiste en una estructura ligera material metálico, la invención propone que la superficie de contacto (17', 24, 31) del elemento de contacto (14) que se apoya contra la parte interior de la rueda (2) se forme en una porción (17, 21, 30) del contacto elemento (14) que consta de material de acero conductor de electricidad, resistente a la corrosión.

The invention relates to a multi-part railway wheel for a railway vehicle, having a wheel tire, having an inner wheel part, having at least one elastic body arranged between the wheel tire and the inner wheel part, which body acts for electrical insulation, by way of which body the wheel tire is supported on the inner wheel part, and having a current bridge that is mounted on an outside end face of the railway wheel which bridge comprises a first contact element that consists of an electrically conductive material and lies against the wheel tire with a contact surface, a second contact element that consists of an electrically conductive material and lies against the inner wheel part with its contact surface and an electrical conductor that connects the contact elements. The inner wheel part consists of a light-metal material, at least in the region in which the contact element of the current bridge, which is assigned to the inner wheel part, lies against the inner wheel part with its contact surface. In order to prevent the risk of the formation of contact corrosion at a contact location, at which a contact element of the current bridge lies against a section of the inner wheel part that consists of a light-metal material, in the case of such a railway wheel, using simple means, the invention proposes forming the contact surface of the contact element that lies against the inner wheel part on a section of the contact element that consists of corrosion-resistant, electrically conductive steel material.
