22、by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards sha
23、ll be withdrawn at the latest by June 2006. This European Standard has been prepared under a mandate given to CEN/CENELEC/ETSI by the European Commission and the European Free Trade Association, and supports Essential Requirements of EU Directive 96/48 and EU Directive 2001/16. For relationship with
24、 EU Directive(s), see informative Annexes ZA and ZB, which are an integral part of this European Standard. This EN 14535 consists of the following parts: Part 1: Brake discs pressed or shrunk onto the axle or drive-shaft, dimensions and quality requirements; Part 21): Brake discs mounted onto the wh
25、eel rim, wheel web or wheel hub, dimensions and quality requirements; Part 31): Brake discs, performance of the disc and of the pad and disc friction couple, classification. Until Part 3 is made publicly available, the existing relevant national standards or other suitable regulations should be used
26、 as an interim solution where prEN 14535-3 is referenced in this document. NOTE On publication of Part 3, Part 1 may be reviewed to take into account any necessary changes. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to
27、 implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Ki

Each manufactur
29、er is therefore responsible for taking every necessary step to make sure that the quality of design, workmanship and construction is such as to ensure accordance with good engineering practice.

30、 1 Scope 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 f
31、it. 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 pr
32、ivate 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. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this European Standa
33、rd, the following terms and definitions apply. 3.1 brake disc rotor having one or more co-planar annular friction faces for the engagement of brake pads and means of transmitting rotation between itself and the associated axle or drive shaft element NOTE 1 It may absorb and dissipate at least part o
34、f the brake energy. NOTE 2 This definition is identical to 4.9.7.10 in EN 14478:2005. 3.2 friction face radially and circumferentially extending planar surface of the disc available for frictional engagement of the brake pad(s) 3.3 brake ring portion of the disc having friction faces NOTE 1 Brake ri
35、ngs constructed from homogenous material between the friction faces are ”homogenous” or otherwise ”non-homogenous”. 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 su
36、rface, 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.

37、EN 14535-1:2005 (E) 7 3.5 non-ventilated disc disc having a continuity of material or materials allowing in that volume no flow of air between the friction faces 3.6 ventilated disc disc in which passages to conduct a flow of cooling air are located between the friction faces of the brake ring NOTE
38、1 The air flow is usually occasioned by the rotation of the disc. 3.7 single disc disc in which one brake ring is associated with one hub 3.8 double disc disc in which one hub supports two axially spaced brake rings 3.9 brake disc temperature arithmetic average value of the measured temperatures of
39、the disc friction face NOTE The temperatures are measured by six sensors as shown in Annex A. 3.10 maximum permissible disc temperature highest operation temperature related to the application NOTE This may be expressed as an absolute peak value or as a nominal value over a defined period of time. 3

47、 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 pre
48、viously; 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 ma
49、nufacture 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 in
