RAILWAY VEHICLE BRAKE PAD

摘要

A brake pad of the type including a friction lining (11) mounted on a support (12) by means of a sublayer (13) of low compressive modulus material is described, wherein an array (A) of grooves, for example (14L, 14T), is recessed at the surface of the friction lining (11), and extends at least to the sublayer (13). The invention provides, in combination, an array (A) of grooves that comprises at least two longitudinal grooves (14L) and at least three transversal grooves (14T), and a sublayer material (13) with a compressive modulus in the range of 800 daN/cm<2> - 100 daN/cm<2>. The invention is useful for railway vehicle disk brakes.
