DIN EN 15329:2015-09 EN 15329:2015(E)5 Introduction The requirements of this European Standard cannot be laid down in such detail as to ensure defect-free design and production without obstructing further development. It is therefore essential f

22、or each manufacturer himself to take all requisite steps to ensure on his part that the quality of design and production are state of the art. DIN EN 15329:2015-09 EN 15329:2015 (E) 6 1 Scope This European Standard applies to brake block holders and brake shoe keys installed on railway vehicles. Bra

23、ke block holders and brake shoe keys made of non-ferrous materials are not subject to this European Standard.

24、brake block holders and brake shoe keys with which the railway vehicles of main-line railways, private railways (regional railways, company railways) are fitted. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for

25、 its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

32、ents shall comply with applicable European Standards. 5.2 Material for brake block holder The brake block holders shall be produced from one of the following: steel (cast, forged or rolled), grey cast iron. Welded designs are permitted subject to agreement between manufacturer and customer. Welding

33、shall only be used for rectification of manufacturing defects, when subject to a formal procedure. 5.3 Material for brake shoe key and brake block key The selection of the material and the manufacturing process are left to the discretion of the manufacturer but they shall comply with the technical s

34、pecifications and/or the drawings approved by the operator. DINEN 15329:2015-09EN 15329:2015 (E) 8 5.4 Corrosion protection If corrosion protection is required, it shall be agreed between manufacturer and customer. It shall not contain any components constituting a hazard for the staff coming into c

35、ontact with them. Should paint colouring be applied, care shall be taken to ensure that bearing points for bolts, bushes and moving parts are free from paint. 6 Design 6.1 Brake block holders 6.1.1 General The purpose of the brake block holders shall provide secure mounting and positioning of the br

36、ake block made of grey cast iron, sintered material or composite material. Sprues, suction heads and sharp edges caused by manufacturing shall be removed. Cast brake block holders shall be normalized. Brake block holders should be designed to accommodate: one brake block (see Figure A.10 and Figure

37、B.11); two brake blocks securely mounted separately in the brake block holder (see Figure A.9 and Figure B.10); two brake blocks mounted separately but with movable supports (see Figure C.1). The curvature of the contact surface of the brake block holder with the brake blocks shall be smooth and hav

38、e the same radius as shown on the figures. The entire length of the contact surface shall be perpendicular to the longitudinal centre plane of the brake block holder so as to ensure large surface contact with the brake block. The same applies to the clearance of the key-hole eyes for guiding the bra

39、ke shoe key and to the recesses for accommodating the brake block mounting cams. The brake block holder shall not become permanently deformed at the maximum brake force. The suitability of the brake block holder shall be demonstrated by determining its fatigue limit by means of the test forces and n

40、umber of cycles stipulated in Clause 8. Repair welding is not permitted. 6.1.2 Dimensional accuracy In order to ensure the interchangeability of the brake block holders and the brake blocks nationally and internationally the main dimensions of the brake block holders shall be as per the circled area

41、s in the figures given in Annexes A and B. 6.2 Brake shoe key/Brake block key 6.2.1 General Some examples of brake shoe keys and brake block keys are given in the figures in Annex C and Annex D. The customer approves the types used. The surfaces shall be smooth and free from corrosion. Burrs and sha

42、rp edges shall be removed before treatment, the required hardness shall be indicated in the technical documentation. 6.2.2 Dimensional requirements The dimensional characteristics shall ensure the interchangeability and shall be agreed between the manufacturer and the customer, and indicated in the

43、drawings. Distortions of the brake block key due to manufacture shall not exceed 2 mm. DIN EN 15329:2015-09 EN 15329:2015 (E) 9 7 Markings 7.1 General Brake block holders, brake shoe keys/insert springs covered by this document shall be provided with permanent markings, as described in 7.2 and 7.3.

44、The marking on the brake block holder shall also be legible when the brake block is fitted. 7.2 Brake block holder The brake block holders shall be marked permanently. The markings shall be applied raised or recessed. The area in which the markings are to be applied shall be shown in the drawing. Th

45、e following details are to be provided: size of the brake blocks employed, e.g. (2 250 mm); outside radius of the brake block, e.g. (560 mm); ownership sign of the railway and year of manufacturing; dimension of the bore-hole for the bushing of the bearing pin, e.g. 60 mm; interchangeability sign an

46、d dimensions of the markings according to Annex G. 7.3 Brake shoe key and brake block key The brake shoe key shall be marked in raised letters in a recessed panel with the markings of the manufacturer and the year of manufacturing. The markings shall not protrude above the surface of the key. For ke

47、ys manufactured by rolling, the markings may also be recessed, but care shall be taken to ensure that the tool used for this purpose does not have any sharp edges which might lead to the creation of fatigue fractures. 8 Type testing 8.1 General 8.1.1 Elements of type testing Type testing consists of

48、 material and component testing. The components presented for acceptance shall comply with the technical documentation for series production (dimensional accuracy, surface conditions but without painting treatment of the surface, material). 8.1.2 Material testing Within the framework of material testing, the manufacturer shall submit all test certificates concerning structural composition and physical/mechanical properties to the customer/user for inspection and approval. The materials used shall exhibit toughness, stip
