Description

5130 2GB 2 och två sidoflänsar 17,18, dvs den har en kulle 14-16 vändinåt fordonet. Locket 12 har ett antal platta partier 20-24 och dessa partier är svetsade till hattbalkens sidoflänsar 17 ,1 8. hattbalken är svagt böjd, vilket framgår av figur 3 som visar lockets 12 böjning. 5130 2GB 2 and two side flanges 17,18, ie it has a hill 14-16 facing the vehicle. The lid 12 has a number of flat portions 20-24 and these portions are welded to the side beams 17, 18 of the hat beam. The hat beam is slightly bent, as can be seen from Figure 3 which shows the bend of the lid 12.

Mellan de platta partierna 20-24 har locket inbuktningar 25-28 som når nästan ända ner till hattbalkens centralfläns 14 och är svetsade liven 15,16, dvs svetsade till insidan på hattbalkens kulle. Inbuktningama 25-28 bör anligga mot hattbalkens innerytor och vara svetsade längs ariliggningen, företrädesvis längs hela anliggningen som anges med _ hänvisningsbeteckningarna 30,31. Figur 7 visar en alternativ form på locket l2 som har flikar 33,34,35 parvis i varje inbuktning. Dessa flikar kan fästas mot hattbalken med punktsvetsning. Hela anliggningen mot liven är således i detta fall inte svetsad och även med linj esvetsning kan man ha uppehåll i svetsen och ändå fâ tillfredställande vridstyvhet. Till och med utan att svetsa inbuktningarna till insidan på hattbalken iår man en mycket förbättrad vridstyvhet.Between the flat portions 20-24, the lid has indentations 25-28 which reach almost all the way down to the center beam 14 of the hat beam and are welded to the webs 15,16, ie welded to the inside of the hat beam hill. The indentations 25-28 should abut against the inner surfaces of the hat beam and be welded along the abutment, preferably along the entire abutment indicated by the reference numerals 30,31. Figure 7 shows an alternative shape of the lid 12 having tabs 33,34,35 in pairs in each indentation. These tabs can be attached to the hat beam with spot welding. The entire abutment against the web is thus in this case not welded and even with line welding you can have a break in the weld and still get satisfactory torsional rigidity. Even without welding the indentations to the inside of the hat beam, this year a much improved torsional rigidity.

Den visade stötfångarbalken får en signifikant förbättrad vridstyvhet utan att vikten ökar särskilt mycket i förhållande till en motsvarande stötfångarbalk med slätt lock.The bumper beam shown has a significantly improved torsional rigidity without the weight increasing particularly much in relation to a corresponding bumper beam with a smooth lid.

Stötfângarbalken kan fästas mot fordonet på olika sätt. Centralflänsen 14 kan exempelvis ha hål för skruvar som fästs i en fàstplatta på fordonet. Locket 12 har då hål 36,37 för att medge åtdragning av skruvarna.The bumper beam can be attached to the vehicle in different ways. The central shaft 14 may, for example, have holes for screws which are fastened to a mounting plate on the vehicle. The cover 12 then has holes 36,37 to allow tightening of the screws.
