Description
449 519 "' 2 Enligt en annan fördelaktig utföringsmöjlighet av uppfinningsföre- målet hålles det direkt anliggande locket slätt, speciellt görs av aluminium- gods till sin helhet. På detta lock påvulkaniseras en plåttäckning i kantområ» det. Därvid kan en flänskant pågjutas för anbringning av varvtalsmätaren, vilken flänskant genom en genomgående urskärning ur den påvulkaniserade plåten säkerställer tillträde utifrån vid monteríngen Denna sistnämnda utföringsmöjlighet behöver visserligen en större materialinsats än den tidigare beskrivna utföringsformen med en flänsram. 449 519 "'2 According to another advantageous embodiment of the object of the invention, the directly adjacent lid is kept smooth, especially made of aluminum goods in its entirety. On this lid a sheet metal cover is vulcanized in the edge area. the speedometer, which flange edge through a continuous cut-out from the vulcanized sheet ensures access from the outside during assembly. The latter embodiment certainly needs a larger material input than the previously described embodiment with a flange frame.
Den utesluter i stället eventuella risker såsom oljeläckage, som kan föreligga vid uppträdande partiell otäthet hos det mjukelastiska mellanskiktet. De minskar därmed kraven på vulkaniseringsprocessens kvalitet. ' Enligt en ytterligare realiseringsmöjlighet kan därvid det stålplåt- look, som dessutom skall anordnas, också vara elastiskt förbundet med det egentliga godslockets ovanyta medelst en skruvförbindning. Därvid anordnas enligt denna utföringsmöjlighet en elastisk skruvförbindning.Instead, it excludes any risks such as oil leakage, which may exist in the event of partial leakage of the soft-elastic intermediate layer. They thus reduce the demands on the quality of the vulcanization process. According to a further realization possibility, the steel plate look, which is also to be arranged, can also be elastically connected to the upper surface of the actual goods lid by means of a screw connection. In this case, an elastic screw connection is arranged according to this embodiment.
Uppfinningeln beskrivs närmare i det följande med hänvisning till den bifogade ritningen, som visar föredragna utföringsformer. Fig. 1 är en partiell sidovy av en grundkonstruktion av ett lock enligt uppfinningen. Fig. 2 är en fragmentarisk sidovyav en elastisk skruvförbindning, som med fördel kan realiseras vid anbringandet av ett lock i överensstämmelse med utfö- ringsformen enligt figur 1.The invention is described in more detail below with reference to the accompanying drawing, which shows preferred embodiments. Fig. 1 is a partial side view of a basic construction of a lid according to the invention. Fig. 2 is a fragmentary side view of an elastic screw connection, which can advantageously be realized when fitting a lid in accordance with the embodiment according to Fig. 1.
I fig. l återges schematiskt en möjlig form av ett styrhjulshus, som skall tillslutas medelst ett lock enligt uppfinningen. Locket är därvid i enlighet med föreliggande uppfinningsförslag utformat med två skikt, nämli- gen av en grunddel 2 och ett huvlock 4. De båda lockskikten 2 och 4 är förbundna med varandra medelst ett mjukelastiskt mellanskikt 3, som är förbundet såväl med grundlocket 2 genom en vulkaniseringsförbindning som med det avslutande locket 4. Grundlocket 2 kan därvid, såsom antyds med streckade linjer 5, utformas som en flänsram, vilken även uppbär axeltätníng- ar. I detta fall måste det mjukelastiska mellanskiktet 3 förlöpa utmed hela flänsramen för att uppnå en tillräcklig avtätning mot utträdande olja.Fig. 1 schematically shows a possible shape of a steering wheel housing, which is to be closed by means of a lid according to the invention. The cover is then in accordance with the present invention proposed formed with two layers, namely of a base part 2 and a hood cover 4. The two cover layers 2 and 4 are connected to each other by means of a soft-elastic intermediate layer 3, which is connected both to the base cover 2 by a vulcanization connection as with the terminating cover 4. The base cover 2 can then, as indicated by dashed lines 5, be designed as a flange frame, which also carries shaft seals. In this case, the soft-elastic intermediate layer 3 must extend along the entire flange frame in order to achieve a sufficient seal against leaking oil.
Vid en annan utföringsform utformas grundlocket 2 som ett slutet plant lock. I detta fall räcker en punktförbindning melllan grundlocket 2 och huvudlocket 4.In another embodiment, the base cover 2 is designed as a closed flat cover. In this case, a point connection between the base cover 2 and the main cover 4 is sufficient.
Såsom framgår av fig. 1 är det fördelaktigt att dra det yttre avslutande locket 4 på sidan runt flänsramen 2 för att dämpa även åt sidan utträdande luftljud.As can be seen from Fig. 1, it is advantageous to pull the outer terminating cover 4 on the side around the flange frame 2 in order to attenuate air noise emanating to the side.
I fig. 2 visas i större skala hur det yttre locket, i detta fall f! 1-7 'W v? 449 519 3 betecknat med hänvisningssiffran 14, kan förbindas mjukelastiskt med grund- locket 12 medelst en skruvförbindning. l detta fail är en skruv 15 förd i en elastisk hylsa 18. Kring den elastiska hylsan 18 anbringas en elastisk ring 16 av en elastomer, pa vilken den yttre hylsan 14 är fastklämd. För att ytterligare säkra och dämpa infogas mellan den mjukelastiska ringen 16 och skruvens 15 huvud en stalskivearmerad underläggskíva 17 av en elastomer.Fig. 2 shows on a larger scale how the outer lid, in this case f! 1-7 'W v? 449 519 3 denoted by the reference numeral 14, can be soft-elastically connected to the base cover 12 by means of a screw connection. In this failure, a screw 15 is inserted in an elastic sleeve 18. Around the elastic sleeve 18, an elastic ring 16 of an elastomer is applied, on which the outer sleeve 14 is clamped. To further secure and dampen, a steel plate-reinforced washer 17 of an elastomer is inserted between the soft-elastic ring 16 and the head of the screw 15.
Av fig. 2 framgar att det kan vara fördelaktigt att den yttre täckningen 14, sasom antyds genom streckade linjer l4', dras runt huset och speciellt grundlocket 12, och att därmed en ytterligare bullerdämpning uppnas.It can be seen from Fig. 2 that it may be advantageous for the outer cover 14, as indicated by dashed lines 14 ', to be drawn around the housing and in particular the base cover 12, and that a further noise reduction is thereby obtained.
Uppfinningen har förklarats med ledning av tre realiserihgsmöjlig- heter. För den pa omradet verksamma fackmannen är det uppenbart att därutöver andra realiseringsmöjligheter för en rnjukelastisk förbindning mel- lan de enskilda skikten av locket är möjlig. Därutöver kan det i det enskilda fallet även vara lämpligt att konstruera locket med tre skikt, varvid alla tre skikten kan vara förbundna genom vulkanisering eller ocksa tva genom en mjukelastisk skruvförbindning och det tredje genom vulkanisering o.s.v.The invention has been explained on the basis of three realization possibilities. It is obvious to the person skilled in the art that in addition other realization possibilities for a knee-elastic connection between the individual layers of the lid are possible. In addition, in the individual case it may also be suitable to construct the cover with three layers, whereby all three layers can be connected by vulcanization or also two by a soft-elastic screw connection and the third by vulcanization and so on.
