BRAKE DISC USING DIFFERENT MATERIALS

摘要

PURPOSE: A brake disc using various materials is provided to ensure the strength of the disc for enduring the maximum braking torque by strongly combining through the strap and the ring-shaped rivet. CONSTITUTION: A brake disc using various materials comprises a disc plate(100), a hat part(200), a strap(400), a rivet(600). The disc plate comprises a rivet hole(162) which is formed on the protrusion between coupling grooves. The disc plate includes a plurality of coupling grooves along the inner circumferential surface of the inserting hole. The hat part is combined on the inserting hole of the disc plate and formed with aluminum alloy. Multiple protrusions for coupling on the outer circumferential surface on the hat part are corresponded to the coupling grooves. The strap is positioned to straddle the rivet holes of the disc plate and the hat part. The rivet fixes and passes through the strap and rivet hole.
