28、5 Introduction The requirements given in this European Standard cannot be written in sufficient detail to ensure good workmanship or proper construction. Each manufacturer is therefore responsible for taking every necessary step to make sure that the quality of design, workmanship and construction i
29、s such as to ensure accordance with good engineering practice. DIN EN 14535-1:2011-07 EN 14535-1:2005+A1:2011 (E) 6 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
30、 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 t
31、o 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 bra
32、ke linings. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this European Standard, 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 rotati
33、on between itself and the associated axle or drive shaft element NOTE 1 It may absorb and dissipate at least part of 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
34、 frictional engagement of the brake pad(s) 3.3 brake ring portion of the disc having friction faces NOTE 1 Brake rings 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 co
35、ntinuous 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
36、separate linking arrangement. DIN EN 14535-1:2011-07 EN 14535-1:2005+A1:2011 (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 a
37、re located between the friction faces of the brake ring NOTE 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 temperat
38、ure arithmetic average value of the measured temperatures of 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
39、 value or as a nominal value over a defined period of time. 3.11 maximum permissible rotational speed highest rotational speed related to the application 3.12 direct actuation brake brake in which the brake pad normal force is applied directly 3.13 indirect actuation brake in which the brake pad nor
40、mal force is applied via a lever system 3.14 part assembly or component uniquely identified 3.15 part number number given to the part by the supplier to designate its characteristics and design 3.16 purchaser vehicle and/or bogie builder, owner, operator or his nominated representative DIN EN 14535-

42、fined limits of structural degradation NOTE Discs are categorized into performance classes according to the tests stated in Part 3 of this European Standard: brake discs, performance of the disc and of the pad and disc friction couple, classification. 3.18 braking energy energy dissipated per disc 3

45、ents 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 pad
46、s, 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 radia
47、tion, 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 o
48、perating 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 d
