摘要

PURPOSE: A facing disc assembly for vehicles is provided to reduce weight and inertia of a facing disc by making at least one groove on one side of the facing disc. CONSTITUTION: A facing disc assembly for vehicles includes a pair of facing discs(30) and a cushion plate(40). Grooves of a designated depth are made on an inner surface of at least one facing disc of the pair of facing discs, and are circumferentially arranged and separated from one another by a designated distance. Outer and inner circumferences of the grooves have a designated curvature, and the outer circumference is longer than the inner circumference. The cushion plate is interposed between the two facing discs, and the edge of the cushion plate has a bent portion(41) which is bent at an certain angle for absorbing vibration and impact.
