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

FIELD: mechanical engineering; friction articles.

SUBSTANCE: proposed friction article contains flat reinforcement skeleton and friction member molded to skeleton. Layer of friction member adjoining skeleton is reinforced additionally by means of notched-and-drawn metal sheet fixed on skeleton by welding. Welded joint is formed by separate spots arranged so that at least two wells spots are located in direction of shifting friction member relative to skeleton in operation.

EFFECT: reduced possibility of thermal deformation of skeleton, increased strength of skeleton-to-friction member joint, simplified process of forming high-strength joint of skeleton and friction member.
