摘要

The disk has an inner friction ring (2), an outer friction ring (3), and a wire structure element (1) arranged between the inner and outer rings. The structure element is connected with one of the rings in a firmly-bonded and/or form-fit manner. The element is designed as an open-cell three-dimensional wire structure, where porosity of the element is maintained between 70 and 95 percent. The element comprises metallic wires, where diameter of the wires lies in the range between 0.1 mm and 3 mm. Connection elements designed as rods or fins are formed in an inner side of the element. The wire structure element is formed as knitted fabric, woven fabric or meshwork.
