31、equirements of UIC leaflet 812-3.In order to be able to adapt 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
32、wheel design shall meet to be accepted on a European network. 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. A
33、t least four aspects are described with different purposes: 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 en
34、sure that no fatigue cracks occur in the web; an acoustical 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 wh
35、eel under study. This standard does not cover assessment of the hub nor of the static mechanical dimensioning of the wheel. DIN EN 13979-1:2011-06 EN 13979-1:2003+A2:2011 (E) 6 1 Scope The aim of this European Standard is to define the requirements that a monobloc wheel of a freight of passenger rai
36、lway 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 the customer and supplier
37、 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 applicable to forged and ro
38、lled wheels for which the quality requirements are defined in !EN 13262“. 2 Normative references !The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referen

If the application parameters are changed for an approved wheel, the customer and supplier sha
41、ll review 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 requirem
42、ents the 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; the tread profile outside the conical part of the tread; DIN EN 13979-1:2011-06 EN 13979-1:2003+A2:2011 (E) 7 the position of the rim
43、 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 equipment. 3.1.2 Assembly requirements the bore diameter; the hub length to
44、 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 machines; the position and shape of the hole and groove for displacement under o
45、il 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 created by the friction of the brake shoes on the rail surface. This energ
46、y may be defined by a power Pa, a time taand a train speed Vaduring 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 and the supplier; the type of brake shoes applied to the wheel (nature, dimensio
47、ns and number). !NOTE For interoperable freight rolling stock, the thermomechanical behavior does not need to be verified when braking to a stop, but only drag braking, because of the lower energy in stop braking.“3.3 Parameters for mechanical assessment The application shall be defined by: the maxi
48、mum 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 t
49、he wheel, in kilometres. DIN EN 13979-1:2011-06 EN 13979-1:2003+A2:2011 (E) 8 3.4 Parameters for acoustic assessment The application shall be defined by all the parameters influencing the noise emitted by the wheel and not directly involved in the design of the wheel to be approved, such as: the reference track on which the wheel is to run; the reference wheel to which the design will be compared; the reference rolling stock and one or more reference speeds; one or two surface roughness spectra representative of the r
