30、 Information Centre, 30 March 2004, Uncontrolled Copy, (c) BSIEN 13979-1:2003 (E) 5 Introduction To date, UIC regulations specified that for a wheel to be used in Europe: its design had to be standardized; it had to conform to the quality requirements of UIC leaflet 812-3. In order to be able to ada
31、pt to new railway working conditions, on the one hand, and to facilitate the introduction of new technical solutions, on the other, it has been necessary to replace the concept of standardization with the definition of specifications that a wheel design shall meet to be accepted on a European networ
32、k. The standard covers these specifications and describes precisely how to assess the wheel design. To be able to apply these specifications, it is essential to define the use of the wheel; this standard also states how to define this use. At least four aspects are described with different purposes:
33、 a geometrical aspect: to allow interchangeability of different solutions for the same application; a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to break; a mechanical aspect: to ensure that no fatigue cracks occur in the web; an acoustical
34、 aspect: to ensure that the solution chosen is as good as the reference wheel, for the use in question. For each of these three latter aspects, the rules proposed tend to limit the procedure, the easier the objectives are to attain by the wheel under study. This standard does not cover assessment of
35、 the hub nor of the static mechanical dimensioning of the wheel. Licensed Copy: Wang Bin, ISO/Exchange China Standards Information Centre, 30 March 2004, Uncontrolled Copy, (c) BSIEN 13979-1:2003 (E) 6 1 Scope The aim of this European Standard is to define the requirements that a monobloc wheel of a
36、 freight of passenger railway vehicle non-powered axle shall meet in order to be able to be used on a European network. For wheels of powered axles or wheels with noise dampers, the requirements may be amended or supplemented. For light vehicles and tramways, other standards or documents accepted by
37、 the customer and supplier may be used. This European Standard only applies to wheels of new design. These requirements are intended to assess the validity of the design choice for the proposed use. The assessment of these requirements is the technical approval procedure. This European Standard is a
38、pplicable to forged and rolled wheels for which the quality requirements are defined in prEN 13262. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text
39、 and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies

41、 bogies Wheels - Product requirement. 3 Parameters for the definition of the application covered The application for which the wheel is to be approved shall be defined by the following parameters. If the application parameters are changed for an approved wheel, the customer and supplier shall review
42、 the assessments. 3.1 Parameters for geometrical interchangeability The application shall be defined by geometrical interchangeabliity parameters divided into three categories according to whether they are linked to functional, assembly or maintenance requirements. 3.1.1 Functional requirements the
43、nominal tread diameter that influences the buffer height and the loading gauge; the maximum rim width linked to the points and crossing and the track brakes; Licensed Copy: Wang Bin, ISO/Exchange China Standards Information Centre, 30 March 2004, Uncontrolled Copy, (c) BSIEN 13979-1:2003 (E) 7 the t
44、read profile outside the conical part of the tread; the position of the rim internal surface relative to the corresponding surface of the hub; the conicity of the hub bore; the space required for disc brakes mounted on the wheel; the space needed on the bogie frame, braking equipment and suspension
45、equipment. 3.1.2 Assembly requirements the bore diameter; the hub length to ensure overhanging of the hub on the wheelseat. 3.1.3 Maintenance requirements the wear limit diameter or the last reprofiling diameter; the wear groove shape; the geometry of the area for wheel clamping on reprofiling machi
46、nes; the position and shape of the hole and groove for displacement under oil pressure; the general rim shape to allow ultrasonic measurement of residual stresses in wheels braked by shoes. 3.2 Parameters for thermomechanical assessment The application shall be defined by: the maximum braking energy
47、 created by the friction of the brake shoes on the rail surface. This energy may be defined by a power P a , a time t aand a train speed V aduring drag braking. If it is defined by other parameters (for braking to a stop, for example), these parameters are defined by agreement between the customer a
48、nd the supplier; the type of brake shoes applied to the wheel (nature, dimensions and number). 3.3 Parameters for mechanical assessment The application shall be defined by: the maximum vertical static force per wheelset; the type of service to be provided by the vehicles that will be fitted with the wheels to be approved: description of the lines: geometric quality of the tracks, curve parameters, maximum speeds . ; running times on these lines; the calculated service life of
