Partikeluppsamlarkoncept för tågskivbroms (English)
Abstract [sv]

Vid användandet av en skivbroms på ett tåg frigörs partiklar i friktionskontakten mellan skiva och belägg. Beroende på den aerodynamiska diametern blir partiklar luftburna, och de anses vara farliga för människans andningssystem. Att fånga upp partiklarna och på så vis förbättra luftkvaliteten är därför fördelaktigt.Olika metoder för uppsamling av de luftburna partiklarna utvärderades och den mest lämpliga valdes för vidareutveckling. En konceptuell lösning, för applicering av denna metod på en Reginaboggi, genererades och utformades.Resultatet är en partikelfångare som renar luft med hjälp av filter med tillräcklig uppsamlingseffektivitet. En central uppsamlingsenhet monteras på boggin, och ansluts med rörledningar till insug monterade vid bromsbeläggen. En fläkt genererar ett luftflöde som transporterar partiklarna genom rörsystemet och filtren.

Abstract [en]

In a train disc brake, the frictional contact will generate wear particles in different size ranges. Depending on the aerodynamic diameter some of the particles become airborne; these are considered to be harmful to the human respiratory system. It is therefore beneficial to collect the airborne particles to improve the air quality.Different methods of gathering airborne particles were evaluated and the most suitable was selected. A conceptual solution in how to apply this on a Regina train bogie was then formulated and designed.The result is a particle collector that purifies the air using filters with sufficient efficiency for the application. A central collection unit is fitted on the bogie, connected by tubes to intakes mounted at the brake pads. The system utilizes airflow created by a fan to transport the particles through the tubing and filters.
