BRAKE LINING FOR A RAILWAY VEHICLE, AND A RAILWAY DISK BRAKE USING THE SAME

A railway brake lining (10) includes one or more primary friction members (11), one or more secondary friction members (12), and a base plate (20). Each of the primary friction members (11) is elastically fastened to the base plate (20) with a spring member in between. Each of the secondary friction...

Beschreibung
Zusammenfassung:	A railway brake lining (10) includes one or more primary friction members (11), one or more secondary friction members (12), and a base plate (20). Each of the primary friction members (11) is elastically fastened to the base plate (20) with a spring member in between. Each of the secondary friction members (12) is fixed on the base plate (20). A minimum distance between the friction members (11, 12) and a center of an axle of a railway vehicle is denoted by r1, and a maximum distance between the friction members (11, 12) and the center of the axle is denoted by r2. The centers of one or more of the primary friction members (11) are located in an area that is at a distance of {r1 + (r2 - r1)/3} to {r1 + 2x(r2 - r1)/3} from the center of the axle. The total slide contact area T1 of the primary friction members (11) and the total slide contact area T2 of the secondary friction members (12) satisfy 2/25 = T2/(T1 + T2). Thereby, even at a time of harsh braking to stop a high-speed running railway vehicle, the contact between the brake disk and the friction members (11, 12) can be maintained in a good state.
