Abstract
Disclosed is a friction assembly for a railway disc brake system, this friction assembly including, on the one hand, a brake head including an upper face with a receiving slide, and a lower face, and on the other hand, shoe of friction material and including a first face which is the friction face, and a second face with a profile member configured to engage with the receiving slide, the shoe including a duct establishing sealed communication between a first space bordered by the first face and a second space bordered by the second face, the friction assembly further including a through-hole of central axis A, provided in the brake head and located in line with the duct, and a connection bushing in the through-hole and forming a connection with the duct. The friction assembly includes a return mechanism capable of pressing the connection bushing against the profile member.
