摘要
FIELD: transport.;SUBSTANCE: group of inventions relates to railway transport. Supporting plate is designed for supporting a plurality of friction material buttons. Supporting plate has a through hole to allow coupling of each button with said supporting plate, a group of first eyelets or slots arranged around said first through hole, and a plurality of second through holes for the insertion of a respective blocking element so as to couple said supporting plate with a base plate. Said first eyelets alternate with first portions of the supporting plate, so that, during braking, in the presence or absence of a temperature difference between said supporting plate and said base plate, said first portions are deformed in the elastic field, due to the effect of normal forces applied on said buttons in such a way that distributions of contact pressure on the buttons are substantially uniform with each other.;EFFECT: uniform distribution of the temperature field on the surface of the disc.;25 cl, 27 dwg
