FRICTION UNIT FOR RAIL BRAKE SYSTEM Russian patent published in 2021 - IPC B61H5/00 F16D65/92 

FIELD: railways.

SUBSTANCE: invention relates to friction unit (16) for rail brake disc system (12) of railway rolling stock (10) containing pad holder (3) containing receiving linkage (4), friction pad (22) containing friction overlay (7) and profile (6) made with the possibility of sliding into receiving linkage (4), while friction pad (22) contains pneumatic channel (9) connecting first space (E1) bounded by first side (71) of friction pad (22), and second space (E2), bounded by second, opposite, side (72) of friction pad (22), through hole (38) made in pad holder (3) to be located opposite pneumatic channel (9), and pneumatic nozzle (5) mounted on pad holder (3), pneumatically communicating with through hole (38), located opposite to friction pad (22) and made movable with the possibility of rotation relatively to pad holder (3) around axis (A8) normal to main plane (XY) of pad holder (3).

EFFECT: creation of the friction unit that allows one to more effectively capture particles that break off from the friction overlay of the friction pad during the braking cycle, and which is easier to integrate into the structure of railway rolling stock.
