Reinforceably constructed disk brake rotor for use in e.g. bicycle, has support part provided with ventilation openings, and carbon fiber layer laminating within support part along edge of ventilation opening around disk rotor part

摘要

The rotor has a disk rotor part (1) provided with a composite part (11) in a middle part to attach the disk rotor part with a wheel hub. A friction part (12) is annularly formed on an outer edge of the disk rotor part, which is connected with brake linings. A support part (13) is annularly formed on the disk rotor part and between the composite part and the friction part. The support part is provided with multiple continuous ventilation openings (131). A carbon fiber layer laminates within the support part along an edge of each ventilation opening around the disk rotor part.
