Abstract
A railway brake lining includes one or more primary friction members, one or more secondary friction members, and a base plate. Each of the primary friction members is elastically fastened to the base plate. Each of the secondary friction members is fixed on the base plate. A minimum distance between the friction members and a center of an axle is denoted by r1, and a maximum distance between the friction members and the center of the axle is denoted by r2. The centers of one or more of the primary friction members are located in an area that is at a distance of {r1+(r2−r1)/3} to {r1+2×(r2−r1)/3} from the center of the axle. The total slide contact area T1 of the primary friction members and the total slide contact area T2 of the secondary friction members satisfy 2/25≤T2/(T1+T2).
