Abstract

The invention relates to an idler wheel arrangement for rail vehicles, consisting of a wheel (2) rotatably mounted on an axle stub (4) of an axle (6), in particular of a cranked straddle axle, and having an inside (12) facing the axle (6) and an opposite outside (16) and of holding means for three functional devices, specifically for an earth-contact arrangement (18), a transmitter arrangement (20) of an anti-slip device and a braking device (22). The holding means having a carrier element (24) fixedly connected on the end face to the axle stub (4) on the outside (16) of the wheel (2). The carrier element (24) has reception means for fixed components (18a, 20a, 22a) of all three functional devices (18, 20, 22), the wheel (2) being assigned reception means for correspondingly associated components (18b, 20b, 22b), rotating with the wheel (2), of the three functional devices (18, 20, 22), in adaptation to the arrangement of the fixed components (18a, 20a, 22a).
