<p>A friction device (1) of a brake or clutch assembly, the friction device has at least one support member (4, 5) supporting a heat transfer material (7) and a friction material, the friction material provides at least one friction surface (8, 9) arranged to contact a cooperating at least one friction element of said assembly, and wherein the heat transfer material has a thermal conductivity higher than that of the support member and includes a layer thereof sandwiched between the at least one support member and the friction material. A further portion is formed as a plurality of heat transfer elements extending through the at least one support member, each said element having a portion thereof exposed to atmosphere, and the heat transfer elements are connected together by the layer for dissipating heat to atmosphere generated in said friction material adjacent said layer during operation of said brake or clutch assembly.</p> |
