FRICTION ITEM Russian patent published in 2013 - IPC F16D65/92 F16D69/04 

FIELD: machine building.

SUBSTANCE: friction item includes a polymer composite friction element fixed on a metal frame. Surface of the metal frame includes metal teeth on the side of polymer composite friction element. Metal teeth are arranged in polymer composite friction element. In addition, the metal frame surface of the item is provided on the side of polymer composite friction element with a cavity located along the edge of polymer composite friction element.

EFFECT: reduction of possibility of destructing the item at operation under conditions of abrupt temperature drops and use of anti-glaze reagents owing to reducing the possibility of friction element delamination from the frame along the perimetre of friction element.
