Description

Federelement 1 Die vorliegende Neuerung bezißh sieh auf ein Feder- element,eidemzwischenzweilattexLeine elastische Zwischenlage festgeheftet iat tmd daß Wesentliche be- steht darin, daß zwischen den die Ober-und Unterseite des Federelements bildenden Platten eine eine Schaum- ieohenlage tcmssaaeiRd Schicht &s laeenfreiem Poly- urethan vorgesehen ist< Damit wiTd eyreieh,. daß an der Außenseitedes Siements keinerlei 3 ? oren TThanden sind und so das Ele : ment vor Verschmu--tzung"Eindringen von Öl und dgl. gesehützt ist. AnBerdes kann diese Mantelschicht auchnoch uy Veränderung der ßederearakteristik des ge- samtenElements herangezogen werden. Eineweitere Auseestaltung besteht bel dee Neuerung darin daß aas e&erelement eine sittlere Bopang asf- weist,bei der Polyurethan mit sehsa&aytige Btr&tur die iRnenwaBung der Bohrung bildet. Wird bei einem der- artigen Element ein mittlerer Borlzen vorgesehene der in seinem Durehmesser dey iBneehyag entsricht so liegt 4 MLSE hA md liegt tiesr Schaumsehicht gseh&tzt, da die Ober-un& Unt, e2platte das Eindringen vou Söhmutz odee-61 verhütet. Saoh iner anderen AusfShrungsöjpm ist soch vorgesehene daß bei Verhandensein der mittlen Behrsg aue di@ In&enwanUng aUß blasenfreiem-Polyurethan besteht Damit wirddann der Schutz und die Glattwandigk-eit.. genau wie im Falle der Mantelsohlight, auch fürdi-e ; Enntu- bohrungerzielt. Eineweitere nsgestaltung der Neuerna keNzeiehaet sich dadurch,. daß die =manteinde-schicht und/oder die Schicht derInaenbehrn o gegesSer der Qbep--and Qhterlatte hochelastisch Polyureth= la, esteht& Durch die unterschiedliche Elastizität der Santelsehieht bzw. der Schicht der inneren Schwung läßt sich bei Druc-und son- stigen Beanspruchungen die gleiche Pedercharakteristik er- zielene wie bei dem Elemente bei dem die Zwischenlage als schaumartige Struktur hervortritt es kann aber auch, je nach Änderung der Elastizität, durch die Einstellung der Härte die Mantel-bzw. Innengehicht eine steilere Feder- kurve erzielt werden. Die Zeichnung veranschaulicht die. Seneruag an swei Ans- führungebefspfelen und zwar zeigt Abb ein Federelement im Schnitt'' Abb. 2 ein Federelement im Schnitt mifgegen- über Abb* t geänderter Ausfuhrungsform In Abb 1 ist eine Oberplatte 1 und eine Shterpl&tte 2 aus hart eingestelltem Polyurethan hergestellt bzw. kam ! auch irgendein anderer fester St&fi zmr ? erwendung komen'Eine Zwischenschicht 3 hingegen besteht aus vorwiegend linearen Hydroxylpolyestern) Diisocyanaten md aus emetzem herge- atelltem Polyurethan, mit schaumartiger Struktur. Die Platten 1 und 2 sind durch eine Mantelechicht 4 miteinander v-er- boden und diese Mantelsehieht besteht aus blasenfreiem Polyurethan das jedoch geenSber den Hatten nd 2 falls diese aus Polyurethan hergestellt sind, weicher dh. ela- optischereingestellt ist* Das ederelement weiät eine mitt- lere Bohrung 5 aufy die zur Aufnahme irgendeines Bolzens odersonstigen Teiles dienen kann. Rierbei tritt die Schattm- struktur 3 auch an der Innenseite der Böhrang herVor. Nach Abt nach derem linken eil die chas&schieht 3 durch die Manteleehieht 4 geschützt. Be der Innenbohrung 5 ist hingegen eine Schicht 6 aus blasenfreiea, elastischen Polyurethan gleicher Art und gleicher Struktur wie Schicht 4 vorgesehen*Sei der rechten Seite ist die jSantelschieht 4 fortgelassenund die schaumartige Struktur 3 der Mittelschicht tritt hier an die Oberfläche. Spring element 1 The present innovation with regard to a spring element, silk between two lattex line elastic Intermediate layer stapled iat tmd that essentials says that between the top and bottom of the spring element forming plates a foam tcmssaaeiRd layer & slaeenfree poly- urethane is provided <So wiTd eyreieh ,. that at the Outside of the Siement no 3? oren TThare and so the element against pollution "penetration of oil and the like. Is protected. In addition, this cladding layer also change the ßederearakteristik of the ge velvet elements are used. There is also a further development in that aas e & erelement a civil Bopang asf- shows, in the case of polyurethane with visually appealing btr & tur the inner wall of the bore forms. If one of the like element a middle Borlzen provided the in his Durehmesser dey iBneehyag arises like that lies 4 MLSE hA md lies the deep foam layer, as the upper and Unt, e2platte the penetration of Söhmutz odee-61 prevented. Another embodiment is also planned that when negotiating the middle Behrsg aue di @ There is therefore no bubble-free polyurethane then the protection and the smooth walling ... exactly as in the case of the Mantelsohlight, also for di-e; Enntu- drilling achieved. A further design of the Neuerna is not a thing of the past through this,. that the = manteinde-layer and / or the layer the inaccessibility against the Qbep and Qhter staff highly elastic polyurethane = la, stands & through different elasticity of the Santelehsehen or the Layer of inner momentum can be determined with pressure and other the same peder characteristics under constant stress aim as in the case of the element in which the intermediate layer is used as Foam-like structure emerges but it can also, depending after changing the elasticity, by adjusting the Hardness of the coat or Inner gait a steeper feather curve can be achieved. The drawing illustrates the. Seneruag to swei ans- Leadership unspecified and that shows Fig. A spring element in section '' Fig. 2 a spring element in section with Above Fig * t modified embodiment In Fig. 1 a top plate 1 and a bottom plate 2 are shown hard-adjusted polyurethane manufactured or came! even any other solid st & fi zmr? use komen'a Interlayer 3, on the other hand, consists of predominantly linear ones Hydroxyl polyesters) diisocyanates made from emetzem atellem polyurethane, with a foam-like structure. The plates 1 and 2 are connected to one another by a jacket layer 4 bottom and this coat is made of bubble-free Polyurethane, however, is better than the hats and 2 cases these are made of polyurethane, softer ie. ela- is optically adjusted * The ederelement white a middle lere hole 5 to accommodate any bolt or other part can serve. The shadow comes close structure 3 also on the inside of the Böhrang. After the abbot after their left hurry the chas & happens 3 protected by the jacket 4. Be the inner hole 5 is, however, a layer 6 made of bubble-free, elastic Polyurethane of the same type and structure as layer 4 provided * On the right-hand side is the jacket layer 4 omitted and the foam-like structure 3 of the middle layer comes to the surface here.
