Abstract
Abstract Wheel hub rotatably carried on a shaft portion, which hub presents a region to which a brake disc is non-rotatably affixed, wherein a circular channel (23) surrounding the shaft portion, open on one side of the hub (6), is provided in the hub (6) radially inside of that region. The wheel hub (6) comprises a substantially cylindrical hub section (32) which merges into a radial flange portion (30) to which a wheel (31) is intended to be securely screwed. The circular channel (23) extends through the entire cylindrical section up to the flange portion. The circular channel (23) is open towards the end of the cylindrical hub section which faces away from the flange portion.
