FRICTION PLATE Russian patent published in 2016 - IPC F16D69/04 F16D65/08 

FIELD: transport.

SUBSTANCE: invention relates to machine building, particularly, to friction brake plates. Friction plate has two or more rows of holes for rivets relatively to plate thin edge. Length of plate arc along internal surface, difference of plate thicknesses by edges, average holes depth change to shoulders of two neighboring rows and difference of plate thicknesses along edges corresponds to certain ratio.

EFFECT: higher reliability owing to optimum rivets holes depth change ratio and difference of plate thicknesses along edges.
