Abstract:
1. An internally ventilated brake disk comprising: two friction rings spaced apart and connected to one another by a plurality of primary, secondary and tertiary webs, wherein channels formed between the primary webs are arranged to conduct cooling air from radially inner end regions of the primary webs toward an outer circumference of the brake disk, the primary webs extend in a curved manner between the radially inner end regions to radially outer end regions of the primary webs, the primary web radially outer ends are oriented essentially radially with respect to the brake disk, the primary web inner end regions are oriented at an angle between 30° and 60° with respect to a tangential line at an inner radius of the brake disk, one of the secondary webs and one of tertiary webs are located between each pair of adjacent primary webs, inner end regions of the secondary webs begin at a distance radially outward relative to the inner end regions of the primary webs, inner end regions of the tertiary webs begin at a distance radially outward relative to the inner end regions of the secondary webs, all web outer end regions are positioned essentially equidistant from one another in a circumferential direction about the brake disk, and the radially inner end region of said secondary web located between adjacent primary webs is located closer to the one of the adjacent primary webs which is next to said secondary web, than to the primary web immediately adjacent to the tertiary web, such that air flow in each channel is approximately equal.
