Abstract

The bumper comprises a cap profile with a cover (10) on its front side. The bumper has a middle section (22) with a lower profile than the side sections (20, 21). The middle section is reinforced by a folded edge (23, 24) extending along at least one of the cap profile side flanges (14, 15).

sauce ~ 523 502 2 o Figurerna 7 och 8 är tvärsektioner i större skala tagna utmed linjerna 7-7 respektive 8-8 i figur 5 och figur 6 och de visar också ett lock som utelämnats i figurerna 5 och 6 . sauce ~ 523 502 2 o Figures 7 and 8 are large-scale cross-sections taken along lines 7-7 and 8-8, respectively, in Figure 5 and Figure 6, and they also show a lid omitted in Figures 5 and 6.

Detaljbeskrivning av visade och föredragna utförlngsformer av uppfinningen Den i figurerna 1-4 visade stötfängarskenan har en hattprofil med en central fläns 11 och två liv 12,13. Liven avslutas med sidoflänsar 14,15. Liven har veck 16,17 som fungerar som deformationstrigger för att initiera ett deformationsförlopp som ger största möjliga energiupptagning. Den centrala flänsen och de tvà liven bildar hattprofilens kulle som kan ha en mer rundad form än visat. Hattprofilen har ett lock 10 som ger stötfàngarskenan en sluten profil, företrädesvis utmed hela hattprofilens längd. Locket 10 visas inte på figurerna 1 och 2.DETAILED DESCRIPTION OF SHOWN AND PREFERRED EMBODIMENTS OF THE INVENTION The bumper rail shown in Figures 1-4 has a hat profile with a central flange 11 and two webs 12,13. The life ends with side flanges 14,15. The waist has folds 16,17 which act as deformation triggers to initiate a deformation process that provides the greatest possible energy uptake. The central flange and the two webs form the hill of the hat profile, which may have a more rounded shape than shown. The hat profile has a lid 10 which gives the bumper rail a closed profile, preferably along the entire length of the hat profile. The lid 10 is not shown in Figures 1 and 2.

Stötfàngarskenan är bàgformad och figur 1 visar stötfàngarskenan infäst som främre stötfàngare med sina sidopartiers 20,21 centrala fläns 11 fäst mot fordonets sidobalkar 18,19 så att stötfàngarskenans öppna sida är vänd utàt fràn fordonet. Stötfångarskenan kan vara direkt fäst i sidobalkarna som visas eller vara fäst i ssidobalkarna med mellanliggande krockboxar.The bumper rail is arcuate and Figure 1 shows the bumper rail attached as a front bumper with the central flange 11 of its side sections 20,21 attached to the side beams 18,19 of the vehicle so that the open side of the bumper rail faces outwards from the vehicle. The bumper rail can be directly attached to the side beams shown or be attached to the side beams with intermediate crash boxes.

Hattprofilen har sin största profilhöjd i sina sidopartier 20,21 såsom visas i figur 4 och den har ett mittparti 22 som har lägre profilhöjd, dvs lägre liv 12,13 såsom visas i figur 3. Mot ändarna utanför infästningarna mof sidobalkarna minskar profilhöjden äter eftersom sidoflänsarna har jämn bàgform. Sidoflänsarna 14,15 är i mittpartiet 22 bredare än i sidopatierna och har sina kanter 23,24 uppvikta och de uppvikta kanterna förstärker mittpartiet 22. Sidoflänsarna 14,15 löper i en jämn bàge medan centralflänsen 11 har fyra böjar 25-28 och en central relativt rak del 29 sà att stötfángarskenan ger plats för fordonets kylare innanför denna raka del 29. Stötfángarskenans design medför att dess stàl kommer att deformeras pà ett sätt som ger effektiv energiupptagning vid en krock och dess vikt blir mindre än vikten pà andra motsvarande stötfàngarskenor med annan design. 523 502 ¿";~°j=_ ggjtf s n u o o u u u - u o n.The hat profile has its largest profile height in its side portions 20,21 as shown in figure 4 and it has a middle portion 22 which has a lower profile height, ie lower waist 12,13 as shown in figure 3. Towards the ends outside the fastenings mof the side beams the profile height decreases because the side flanges has an even arcuate shape. The side flanges 14,15 are wider in the middle portion 22 than in the side patches and have their edges 23,24 folded up and the folded edges reinforce the middle portion 22. The side flanges 14,15 run in a smooth arc while the central flange 11 has four bends 25-28 and a central relative straight part 29 so that the bumper rail provides space for the vehicle's radiator inside this straight part 29. The design of the bumper rail means that its steel will be deformed in a way that provides efficient energy absorption in a collision and its weight will be less than the weight of other corresponding bumper rails with other design . 523 502 ¿"; ~ ° j = _ ggjtf s n u o o u u u - u o n.

Figurerna 1-4 visar en symmetrisk stötfångarskena och figurerna 5-8 visar en modifierad variant som är osymmetrisk. Hänvisningsbeteckningarna är desamma i de båda utföringstormerna enligt uppfinningen och utföringsformen enligt figurerna 5-8 beskrivs enbart i de delar som skiljer sig från utföringsformen enligt figurerna 1-4. För detaljer som saknar beteckningar hänvisas till figurerna 1-4.Figures 1-4 show a symmetrical bumper rail and Figures 5-8 show a modified variant which is asymmetrical. The reference numerals are the same in the two embodiments according to the invention and the embodiment according to Figures 5-8 is described only in the parts which differ from the embodiment according to Figures 1-4. For details that do not have designations, see Figures 1-4.

Stötfångarskenan enligt figurerna 5-8 har den centrala flänsen 11 smalare så att övre livet 13 är indraget i mittpartiet 22 som bäst visas i figur 6 Den undre sidoflänsen 14 är väsentligen rak sedd i horisontalplanet medan den övre sidoflänsen böjer nedåt från sidopartierna 20,21 mot mittpartiet 22. Denna indragning kan i vissa fall behövas om motorhuven är mycket låg så att man med den symmetriska stötfàngarskenan inte kan få ett luftinsläpp på stötfångarsidans ovansida. Den mesta luften till kylaren tas numera in under stötfângarskenan, men ett extra luftinsläpp erfordras oftast även på stötfångarskenans ovansida.The bumper rail of Figures 5-8 has the central flange 11 narrower so that the upper web 13 is retracted into the central portion 22 as best shown in Figure 6. The lower side flange 14 is substantially straight in the horizontal plane while the upper side flange bends downward from the side portions 20,21 towards the middle section 22. This retraction may in some cases be necessary if the bonnet is very low so that the symmetrical bumper rail does not allow air to enter the top of the bumper side. Most of the air to the radiator is now taken in under the bumper rail, but an extra air intake is usually also required on the top of the bumper rail.

När stötfángarskenan är osymmetrisk pà detta sätt kommer deformationen inte att bli symmetrisk och en uppvikt kant på den undre sidoflänsen 14 skulle inte ge så stort tillskott till energiupptagningen. Den övre sidoflänsen 15 har kvar sin uppvikta kant 24 medan den undre sidoflänsen därför saknar uppvikt kant. I vissa fall kan man emellertid i stället vilja ha uppvikt kant på bàda sidoflänsarna eller endast på den undre.When the bumper rail is asymmetrical in this way, the deformation will not be symmetrical and a folded edge of the lower side flange 14 would not provide such a large addition to the energy absorption. The upper side flange 15 still has its folded edge 24 while the lower side flange therefore has no folded edge. In some cases, however, you may instead want to have a folded edge on both side flanges or only on the lower one.

Stötfångarskenans hattprofil kan lämpligen tillverkas med presshärdningsmetoden där ett ämne i härdbart stål, exempelvis borstål, varmformas i kylda verktyg och härdas medan de ligger kvar i verktygen med verktygen som fixtur. Man kan då nå mycket höga hållfastheter med sträckgränser pà upp till och även över 1500 N/mmz. Hattprofilen kan också kallformas i höghállfast kallformningsstál, men då kan normalt inte lika höga hållfastheter uppnås.The cap profile of the bumper rail can suitably be manufactured by the press hardening method where a blank in hardenable steel, for example boron steel, is thermoformed in cooled tools and hardened while remaining in the tools with the tools as fixture. You can then reach very high strengths with yield strengths of up to and also above 1500 N / mmz. The hat profile can also be cold-formed in high-strength cold-forming steel, but then normally not as high strengths can be achieved.
