Abstract: An insert element for a vehicle wheel comprises several supporting bodies for supporting the insert element on supporting surfaces of the vehicle wheel. The supporting bodies have a supporting shoulder, which can be brought to bear against a supporting surface of the vehicle wheel, and a fastening extension with an axial hollow channel and with at least one outwardly protruding locking projection, arranged at an axial distance from the supporting shoulder, for engaging behind an installation opening reaching through the supporting surface of the vehicle wheel. The supporting bodies are designed as elastomer components which are elastically deformable in the radial and axial direction and sit with their hollow channel on a supporting core. The supporting cores bear a radially protruding retaining flange and are held on the rear side on the insert element. Each supporting body is held by the retaining flange in a form-fitting manner against being pulled off from the supporting core.

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).

Abstract: An idler wheel axle for single-axle or double-axle chassis of rail vehicles having individually mounted wheels and U-shaped, dropped-framed vehicles with lateral carrying legs, wherein each wheel is rotatably mounted on the inside of the associated carrying leg, and on an axle stub of the carrying leg via a wheel mounting, and wherein each wheel is torsionally connected on an inside thereof to a shaft that extends outward through orifices within the wheel and the carrying leg.

Abstract: A brake for rail cars comprises a floating caliper disc brake attached to a cylindrical housing element of a drive housing. The drive housing may be the motor housing, the transmission housing or a common housing for the drive motor and the transmission. The cylindrical housing element has an opening in its peripheral wall in which the floating caliper is mounted. The actuator is mounted in an entry in the peripheral wall of the drive housing. This mounting arrangement allows easier accessiblity to the brake during servicing operations and provides for ventilation of the brake disc.
