Ventilated ceramic brake disc for vehicle, has axial central recess with fastening ring and radial cooling channels having central air inlets and peripheral discharge

摘要

The ceramic disc (1) has an axial, central recess (4) with fastening ring (11) connecting to it on a flat side (10, 7) and joined to the disc body (1). In the disc, largely-radial cooling channels (2) discharge at its outer periphery (3) and are connected with inlets (5) near the inner circumference of the central recess. These transition into the flat face (7) of the disc at an open entry zone (5.1). They are covered over by a vent ring (16) in the form of a circular ring disc.
