PLATE FOR SUPPORTING FRICTION MATERIAL BUTTONS FOR DISC BRAKES OF RAILWAY WHEELED VEHICLES AND FRICTION PAD COMPRISING SAID PLATE

摘要

The present invention relates to a support plate (1) for supporting a plurality of friction material buttons (T) for a disc brake of a railroad vehicle, and at least one agent for coupling the support plate (1) and each button (T). 1 Through hole (F1)-The first through hole (F1) forms a region, and the group of the region of the first through hole (F1) forms a center of gravity (BA) on the support plate (1)-, one At least one group of first eyelets or slots 5 arranged around the first through hole F1-each group of first eyelets 5 comprises at least two first eyelets 5-, A plurality of second through holes (F2) for insertion of each blocking element (MB) to couple the base plate (2) and the support plate (1)-The second through hole (F2) is Arranged adjacent to the periphery, wherein the first eyelet 5 alternates with the first part 7 of the support plate and accordingly the base plate 2 and the support plate 1 in the braking stage of the railway vehicle When there is or is not a temperature difference between the first part 7 is deformed within the elastic range due to the normal force applied on the button T so that the distribution of the contact pressure on the button T is substantially uniform. . The invention also relates to a friction pad comprising a support plate.
