Railway applications - Brake discs for railway rolling stock - Part 1: Brake discs pressed or shrunk onto the axle or drive shaft, dimensions and quality requirements
This European Standard specifies requirements for the design, dimensions, performance, and testing of the brake disc, hereafter called "disc". This European Standard applies to discs secured at the axle or drive-shaft of railway rolling stock by a cylindrical or conic tapered interference fit.
For each discrete unit so fitted, one or more disc brake rings, each having two axially separated friction faces, may be deployed.
This European Standard applies to discs designed to be fitted to rail vehicles used on the main national networks, urban networks, underground railways, trams and private networks (regional railways, company railways etc.).
NOTE This European Standard should be used in association with the standards prEN 15328 and CEN/TC 256 N 185 covering disc brake linings.

NOTE 2 Brake rings can consist of one or more sectors and can have continuous or non-continuous friction faces. 3.4 hub portion of the disc having an internal cylindrical or conical surface, the hub bore, for interference fit engagement with the axle or drive shaft NOTE The hub can be constructed integrally with the brake ring (monobloc disc) or connected to it by a separate linking arrangement.

EN 14535-1:2005 (E) 9 5 Requirements 5.1 Purpose The discs are intended to be used as part of a friction brake and shall fulfil the following purposes: permit a braking moment or torque to be generated, supported and transmitted to the rail vehicle axle or drive shaft element; permit, by frictional engagement of a brake pad or pads, the conversion into heat of the kinetic and potential energy involved in retarding the vehicle or vehicles which is attributed to the use of the disc brake; absorb part or all of the kinetic and potential energy arising from the process described previously; dissipate the absorbed energy by radiation, convection and conduction. In achieving these requirements the disc shall not suffer damage or degradation other than normal wear of the friction face beyond permissible limits. 5.2 Materials, design and manufacture a) The materials, design and manufacture of the disc shall, for all intended operating conditions, take into account the following: in the case of discs mounted on the axle, the vehicle gauge when the rail wheels are at their minimum permitted diameter; rotational speed; magnitude of the brake moment or torque; quantity of brake energy to be converted and dissipated and its rate of conversion and dissipation; frictional working conditions, especially of the brake pad; self ventilating fan driving losses; noise; mass of disc; imbalance of disc; environmental influence, e.g. storage, transport, climatic, shock and vibration conditions; integrity, life and maintenance requirements of the disc, associated brake components, and brake and vehicle systems. Where a disc consists of more than one constructional element designed for in-service replacement of the brake ring or part of it, the associated parts of that disc shall be interchangeable while the hub or carrier remains installed on the axle or shaft within the vehicle. SIST EN 14535-1:2006
EN 14535-1:2005 (E) 10 Where the purchaser specifies that during maintenance procedures the hub bore is to be enlarged, the design shall accommodate such enlargement. The design shall be such as to prevent the detachment of any part of the disc at any braking conditions and at any rotational speed up to the maximum permissible rotational speed in all degraded conditions (e.g. wear, cracking) up to the limits specified by the supplier. NOTE 1 The purchaser may specify special conditions for manufacture. NOTE 2 The purchaser may specify special characteristics for the materials used, etc. 5.3 Dimensions 5.3.1 Brake disc The disc major dimensioning notation shall be as shown in Figure 1 and the preferred ranges of major interface dimensions as specified in Table 2.
