Beskrivelse:Description:
Opfindelsen omfatter et monteringsprincip der med fordel kan anvendes ved ’ fastgørelse af rørhale på afgangsrøret af et udstødningssystem.The invention comprises a mounting principle which can advantageously be used in attaching the tailpipe to the outlet pipe of an exhaust system.
* 5 Rørhalen består af et cylindrisk yderrør (1), der er monteret med et konisk inderrør (2).* 5 The pipe tail consists of a cylindrical outer tube (1) mounted with a conical inner tube (2).
Inderrøret, der er monteret forrest i rørhalen, tvinger afgangsrøret til centrum af rørhalen og man sikrer således en centreret montering af rørhalen.The inner tube, which is mounted in the front of the pipe tail, forces the outlet pipe to the center of the pipe tail and thus ensures a centered installation of the pipe tail.
For at opnå en klemeffekt, er der et par centimeter fra den bageste ende på rørhalen 10 isat et fjederbånd (3), der har en vinkel på 90°. Fjederbåndet sidder i spænd med vinklen op i en udbulning (5) og benene spreder ud mod indersiden af yderrøret. Fjederbåndet er ’’knækket” på langs på det yderste stykke således, at der er opstået skarpe kanter, der kan ’’gribe fat” i afgangsrøret (tegn. 2).To obtain a clamping effect, a few centimeters from the rear end of the pipe tail 10 is inserted a spring band (3) having an angle of 90 °. The spring band is tensioned with the angle up into a bulge (5) and the legs spread out towards the inside of the outer tube. The spring band is '' cracked 'longitudinally on the outermost such that sharp edges are formed which can' 'grip' the discharge tube (Fig. 2).
15 På den modsatte side af fjederbåndet er der monteret to nittebøsninger (4) til eksempelvis pinolskruer, som ved monteringen skal spændes til ind på afgangsrøret.15 On the opposite side of the spring belt, two rivet bushes (4) are mounted for, for example, pin screws, which must be tightened to the discharge pipe during installation.
Dette monteringssystem er tænkt som afløsning af den hidtil kendte metode med spændebånd. Det giver en bedre og sikrere montering idet der er to fikseringspunkter; 20 det koniske inderrør, som centrerer afgangsrøret samt fjederbåndet, som sammen med pinolskrueme holder rørhalen fast bagest.This mounting system is intended as a replacement of the previously known method of strapping. It provides a better and safer mounting as there are two fixing points; 20 the tapered inner tube, which centers the discharge pipe and the spring belt, which together with the pin screws hold the pipe tail firmly in the rear.
Det gamle system med spændebånd havde ulempen, at rørhalen meget let kunne komme til at sidde skævt idet fastgørelsen udelukkende var ved hjælp af 25 sammensnævring i bagenden.The old system of straps had the disadvantage that the pipe tail could very easily sit crooked as the fastening was only by means of 25 narrowing at the rear end.
Opfindelsen forklares nærmere på tegning nr. 1, hvor figur ’’front view” og ’’left view” viser rørhalen set fra siden, det vil sige man ser yderrøret samt placering af nittebøsninger samt udbulning. Figuren ’’top view” viser rørhalen fra oven set fra den 30 forreste ende. Man kan således se yderrøret med inderrøret placeret indeni. Figuren ’’section view A-A” viser et snit gennem fjederbånd og nittebøsningeme/pinolskruerne og man kan ligeledes se fjederbåndets placering ud i udbulningen. Figuren ’’section view B-B” viser et tværsnit på langs ned gennem inderrøret, og illustrerer det koniske, som vil tvinge afgangsrøret mod centrum ved monteringen. Figuren ’’isometric 35 view”viser hele rørhalen set skråt fra bunden. På denne illustrationen kan man se alle rørhalens elementer og sammenhængen mellem disse.The invention is explained in more detail in drawing # 1, where the figure '' front view 'and' 'left view' shows the pipe tail as seen from the side, that is to say the outer tube as well as the location of rivet bushes and bulge. The figure "top view" shows the pipe tail from above from the front 30 end. One can thus see the outer tube with the inner tube located inside. The figure '' section view A-A 'shows a section through the spring belt and the rivet bushes / pin screws and one can also see the position of the spring belt in the bulge. The figure '' section view B-B '' shows a longitudinal cross-section through the inner tube, and illustrates the taper which will force the discharge tube towards the center during mounting. The figure '' isometric 35 view '' shows the entire pipe tail as seen from the bottom. In this illustration you can see all the elements of the pipe hall and the connection between them.
På tegning nr. 2 ses hvorledes fjederbåndet er ’’knækket”. Dette ’’knæk” har denne funktion ved monteringen, at der er opstået skarpe kanter, der ’’griber fat” i 40 afgangsrøret.Drawing # 2 shows how the spring band is '' broken ''. This '' crack '' has this feature when mounting that sharp edges have been formed that '' grab '' the 40 discharge pipe.
