Železniške naprave - Zavore - Preprečevanje zdrsa koles

Ta evropski standard določa merila za sistemsko sprejemljivost in tipsko odobritev sistema za preprečevanje zdrsa koles (WSP). Določa tudi merila za izvajanje preprečevanja zdrsa koles za posebne železniške naprave in posebne obratovalne pogoje ter zahteve za nadzor vrtenja koles (WRM). To vključuje načrtovanje, preskušanje in oceno kakovosti sistemov za preprečevanje zdrsa koles in za nadzor vrtenja koles ter njihovih sestavnih delov.
Ta evropski standard se ne uporablja za določanje zmogljivosti zaviranja vlaka, opremljenega s sistemom za preprečevanje zdrsa koles, pri vseh okoljskih pogojih.

Introduction

A Wheel Slide Protection (WSP) system is designed to make the best use of available adhesion and to

improve adhesion by a controlled reduction and restoration of the brake force to prevent wheel sets

from locking and uncontrolled sliding due to low adhesion. Thus the braking performance is optimized

and the occurrence of wheelset damage is minimized.

The Wheel Rotation Monitoring (WRM) system is designed to detect locked wheels and to give

immediate information in this case.

Trains fitted with WSP systems may consist of single vehicles, locomotive and trailing vehicles or may

be high speed trains, multiple units, commuter trains, Light Rail Vehicles (LRV) and Tram Trains of any

track gauge, etc.

Such trains will be equipped with friction brakes and may also be equipped with additional braking

systems, e.g. dynamic brakes, wheel/rail adhesion independent brakes, and may also be fitted with

adhesion improving systems, e.g. sanding.

This European Standard is not intended to be used to determine the stopping performance of a WSP

equipped train under all environmental conditions.
