FRICTION ARTICLE Russian patent published in 2006 - IPC F16D69/02 F16D66/02 

FIELD: mechanical engineering.

SUBSTANCE: friction article comprises metallic frame, friction member made of a polymeric composition and secured to the metallic frame by means of adhesive layer, and means for indicating wear of the friction material. The means for indicating the friction member wear is made of the substrate whose thickness is uniform and is no less than the permissible thickness of the worn friction member. The substrate is positioned from the side of the metallic frame and is made of as polymeric composition as the friction member. The substrate is additionally provided with particles of the material which sounds in the friction of the substrate on the metallic surface, which indicates that the thickness of the worn friction member reaches its permissible value.

EFFECT: enhanced reliability.
