Title: Semi-metallic friction member
Inventor: NAKAGAWA MITSUHIKO
IPC: F16D69/02
Filed: 1981-03-03
Abstract: PURPOSE:To prevent the generation of buildup and sidestep the generation of impact at braking by a method wherein fiber steel or granulated steel removed its blue shortness is employed as the semi-metallic friction member for the brake of vehicle, industrial machinery and the like. CONSTITUTION:The fiber steel or granulated steel (such as, for example, sponge iron powder, atomized iron powder, iron chips or the like) or both in one are employed as the structure member of the semi-metallic friction member and applied in advance by blue shortness (hot shortness) removing treatment before their blending. In this case, a heat treatment with wet hydrogen or other method is employed as the blue shortness removing treatment. As a result, even the temperature rise owing to the friction heating during the latter half period of braking does not produce the buildup or abrupt rise of friction factor just before the stopping of the vehicle, resulting in giving no disagreeable impact to riders caused by the generation of abrupt braking force at the stopping of the vehicle.
