Abstract
Sammandrag En rullformad stotfangarbalk har sluten tvarsektion med utmed langden konstant tvarsektionen som har minst tva slutna kammare (15,16) skilda at av en vasentligen horisontell mellanvagg (14). Varje kammare har en fran fordonet vand sida (19) med minst en utmed hela langden langsgaende konkav del (20,21; 22,23) och en mot fordonet vand sida (24) med minst en utmed hela langden langsgaende konvex del (25,26. 27,28). Efter rullformningen kan man pressa ihop vissa delar av tvarsektionen vertikalt eller horisontellt far att anpassa deformationsegenskaperna.
Description
2 Figur är en sektion tagen utmed linjen 5-5 i figur 3. Figurerna Beskrivning av visade exempel pa uppfinningen Figur 1 visar en statfangarbalk 11 som har tva krockboxar 12,13 fastsvetsade. Statfangaren 11-13 är avsedd som fordonets framre stotfangare och krockboxarna är anpassade aft fastas i fordonets sidobalkar. Figur 2 visar statfangaren sedd framifran och figur 4 visar statfangarbalkens tvarsektion som är konstant utmed hela langden.
Fran ett stalband rullformar man i en kontinuerlig process en profil som sedan kapas i lamplig langd. Man kan rullforma sa aft profilen blir konvex som framgar av figur 1. Alternativt kan man bocka varje langd efter kapningen.
Som framgar av figur 4 rullformar man profilen till aft ha ett vertikalt liv 14, dvs en vasentligen horisontell mellanvagg 14 som avdelar profilen i en ovre och en undre kammare 15,16. Integrerat med rullformningen lasersvetsar man lapande fast profilens langsgaende kanter till profilens sidor vid 17,18 sa aft man far en styv profil. Livet akar bade vridstyvheten och bajstyvheten. Livet är ocksa viktigt far deformationsforloppet och akar energiabsorberingen vid krock. Den sida 19 som är riktad framat, dvs utat fran fordonet, har for var och en av kamrarna en konkav del som bestar av tva vasentligen plana sidodelar 20,21; 22,23 i vinkel mot varandra. Den bakre sidan 24,dvs sidan vand mot fordonet, har en motsvarande konvex del som bestar av vasentligen plana sidodelar 25,26; 27,28 i vinkel mot varandra. Den framatvanda sidan 19 har sina traffytor vasentligen utmed en rat linje som är vasentligen vertikal.
Stattangarbalken enligt figur 3 ar en modifiering av den enligt figur 2. Ett parti 32 av dess langd har tryckts ihop vertikalt sá aft det fatt tvarsektionen visad i figur 5. Framsidan 19 pa vane kammare 15,16 är konvex och baksidan 24 konkav och daft kommer bredden pa tvarsektionen aft Okas vid hoptryckningen vilket akar bojstyvheten lokalt. Den Okade bojstyvheten vid statfangarbalkens mitt som erhalls enligt figur 3 minskar risken for aft det ska bildas eft veck vid krockbelastning rakt framifran, som medfar aft statfangarbalken kollapsar lokalt. Genom horisontell pressning kan man bade andra stotfangarens radie, vilket ofta ar Onskvart vid 3 stOtfangarens andar. Man kan med horisonell pressning ocksa minska bOjstyvheten lokalt aven om man inte Onskar andra stotfangarens radie.
Genom aft pa detta satt trycka ihop delar av stOtfangarbalkens langd kan man till mycket lag kostnad styra stotfangarbalkens beteende vid krockbelastning trots aft perimetern är konstant. Man far ocksa mOjlighet aft anpassa en och samma grundprofil till olika fordon. Man rullformar profilen i en kontinuerlig anlaggning och kapar lampliga langder och Or onskade hoptryckningar av grundprofilen for anpassning till olika fordon. 4
