Brake disk contains through channels (7) running across primary vanes (4) skewly to the inter-vane space (5). At least part of the brake disk body (1) is equipped with a static cover (8) in which a system of secondary vanes (9) is located. Channels (7) are preferably arranged in rows, where they have a bore increasing with increasing distance from the brake disk centre. The secondary vanes (9) are in the number of at least the number of primary vanes (4) and their impact surfaces (10) are directed against the cooling air flow direction. Primary vanes (4) and secondary vanes (9) are bent, but inversely. There are primary gaps between secondary vanes (9) and circumferential wall (13) of a cover (8), and secondary gap inter-connected with primary gaps is between the brake disk and supporting wall (11) of the cover (8). Space around the brake disk body (1) is interconnected with channels (7) and led out through the wheel disk outside the wheel. |
