BRAKE DISC USING DIFFERENT MATERIALS AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a brake disk made of different materials and a method for manufacturing the same and, more specifically, to a brake disk made of different materials, which comprises: a friction part, wherein a coupling hole is located at the center and a protrusion part and an indentation part are alternately repeated along the circumference of the coupling hole, wherein the indentation part is curved outwards from the coupling hole; and a hat part made of a different material from the friction part, wherein an insertion groove inserted with the protrusion part is arranged along the outer circumference and a method for manufacturing the same. The insertion part of the protrusion part at a predetermined gap from the inner side of the friction part is coupled to the insertion groove of the hat part to form a heat radiation hole along the circumference of the coupling hole at regular intervals. Therefore, the brake disk has excellent durability in harsh conditions.
