FRICTION ITEM Russian patent published in 2014 - IPC F16D65/92 F16D69/02 

FIELD: machine building.

SUBSTANCE: friction item includes a metal frame and a polymer composite friction element moulded onto it. A polymer damping layer and an anti-noise metal plate with bent elements is fixed on the metal frame surface. The surface of the polymer damping layer, which faces the anti-noise metal plate, has projections. An additional polymer layer is fixed on the surface of the polymer damping layer, which contains the projections; with that, the above polymer damping layer is fixed on the metal frame surface.

EFFECT: increasing the noise absorbing ability of an item; simplifying fixation of the anti-noise plate; simplifying the anti-noise plate structure as a whole.
