Each manufacturer is therefo

27、re 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. BS EN 14535-1:2005+A1:2011EN 14535-1:2005+A1:2011 (E) 6 1 Scope This European Standard specifies requirements for the d

28、esign, 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 rin

29、gs, 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

30、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 Standard, the following terms and definitions apply. 3.1 brake disc ro

31、tor 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 of the brake energy. NOTE 2 This definition is identical to 4.9.7

32、.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 rings constructed from homogenous material between the friction fa

33、ces 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 surface, the hub bore, for interference fit engagement with the ax

34、le 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. BS EN 14535-1:2005+A1:2011EN 14535-1:2005+A1:2011 (E) 7 3.5 non-ventilated disc disc having a continuity of material or materials allowing in that vo

35、lume 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 1 The air flow is usually occasioned by the rotation of the disc. 3.7 single disc disc in which one brake ring is a

36、ssociated 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 the disc friction face NOTE The temperatures are measured by six sensors as shown in Annex A. 3.10 maximum permissi

37、ble 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. 3.11 maximum permissible rotational speed highest rotational speed related to the application 3.12 direct actuation

44、 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 par

45、t 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 permis

46、sible 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 diam

47、eter; 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

48、; 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 re

49、placement 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.
