A wheel hub and brake disc arrangement for a vehicle wheel includes a wheel hub with alternately following grooves and teeth with inclined flanks, and a brake disc, carried on the part of the wheel hub, having a concentric opening which is formed with corresponding teeth and grooves which are adapted to the grooves and teeth of the hub, the brake disc being locked against rotation on the hub and having a slip fit between the disc and the hub. In order to reduce the heat transfer between hub and disc and minimize the stresses in the disc caused by the temperature distribution and the mechanical effects, the tip arc length for each tooth is less than the root arc length for each groove which is delimited by two opposing flanks of adjacent teeth, the flanks each merge at the respective root side of the teeth into a first radius Ra, which in turn emerges into a second radius Rb which forms the bottom of the groove and is common for the two opposing flanks.
Wheel hub and brake disc arrangement for a vehicle wheel, comprising a wheel hub on a shaft part rotatable mounted in bearings around a central shaft, having a part with an external cross-section profile shaped with alternating grooves and teeth with inclined flanks, and a brake disc, carried on the wheel hub on said part, having a concentric opening which is shaped with corresponding teeth and grooves fitting on to the grooves and teeth of the hub so that the brake disc is non-rotatably locked onto the hub and that there is a sliding fit between the disc and the hub, and on the brake disc the tip arc length for each tooth is less than the root arc length for at least every second groove which is delimited by two opposing flanks on the adjacent teeth,
