DIN 27204-7
State of railway vehicles - Running gear - Part 7: Bogie and equipment
Zustand der Eisenbahnfahrzeuge - Fahrwerk - Teil 7: Drehgestell und Ausrüstungsteile
Overview
behaviour, the operating parameters and the current state of the railway vehicles as well as the economic efficiency, a maintenance system shall be defined which ensures that the required technical target state is maintained. This standard DIN 27204-7 "State of railway vehicles - Running gear - Part 7: Bogie and equipment" has been prepared by Subcommittee NA 087-00-15-04 UA "Running gear" of Working Committee NA 087-00-15 AA "Zustand der Eisenbahnfahrzeuge" ("State of railway vehicles") of the DIN Standards Committee Railway (FSF), in coordination with other FSF working committees and the German Commission for Electrical, Electronic and Information Technologies (DKE). The standards of the overall work "State of railway vehicles" represent a uniform and system-compatible normative work which defines the limit state for safe operation as well as processes for compliance with the target state of railway vehicles of standard gauge. The general scope of this standard is therefore defined in DIN 27200:2011-11 in Clause 1 and Subclause 3.1. All documents of the complete work are listed in DIN 27200 Supplement 1. DIN 27204 "State of railway vehicles - Running gear" consists of: - Part 1: remains open - Part 2: remains open - Part 3: Wheel-set bearings and wheel-set bearing guide (withdrawn) - Part 4: Steel springing - Part 5: Rubber suspension systems - Part 6: Pneumatic suspension system - Part 7: Bogie and equipment - Part 8: Tilting technology (withdrawn) - Part 9: remains open - Part 10: Vehicles without bogies. This standard DIN 27204-7 specifies the technical target state for bogies and their equipment. The specifications made in this standard refer to the bogie with the associated functional components unless separately regulated as a standard in the DIN 27204 series of standards. This standard shall apply mutatis mutandis in the case of designs deviating from those specified. This standard differs from DIN 27204-7:2006-04 as follows: a) adaptation of the foreword; b) adaptation of the scope of application; c) side bearers added as Position 12 in Figure 7; d) Figure 4 spring suspension newly included using the example of a double shackle; e) Table 1 completely revised, among other things: 1) serial no. 1 - grinding marks specified, 2) serial no. 7 - requirements for spring eye and spring bolt as well as state of link suspension newly included, 3) serial no. 8 - requirements amended by references according to DIN 27204-4, 4) serial no. 9 - grooves specified, 5) serial no. 10 - fasteners and safeguard devices as new serial no. 11 and renumbered, 6) serial no. 11 - Requirements for fasteners and safeguard devices renumbered, 7) serial no. 12 - with regard to welding defects, reference is made to the assessment classes of EN ISO 5817, 8) serial no. 13 - requirements for lateral play limitation included as new serial no.13, 9) serial no. 15 - references to DIN VDE 0119-206-5 and DIN VDE 0119-206-7 included in remark; f) editorial changes.
