Method of making a friction disc

摘要

Each of the friction pads (33) is assembled of several segments (33.1, 33.2) joined by engaging the outer ends (36.1, 37.1), each provided with a snakehead-shaped extension (34.1a, 35.2a) and a matching insertion area (34.1c, 35.2c). One of the head shapes is fitted with a round hole, an opening in a shape similar the outer contours is provided at the opposite head. Two triangular openings are integrated in the space above and below the first snakehead.
