Wheel hub assembly

摘要

A wheel hub assembly includes an internally ventilated brake disc. The brake disc is mounted on a flange-like extension of the inner bearing ring of the assembly. Slots are formed in the flange-like extension and the brake disc acts as a cover over the slots forming cooling channels extending radially outwardly in the wheel hub assembly to the cooling apertures in the radially outer part of the brake disc. A heat insulated cover disc can be positioned between the brake disc and the slots in the flange-like extension.
