Description

  

  Ressort<B>à</B> lames    La présente invention est relative<B>à</B> un ressort  <B>à</B> lames, qui convient particulièrement aux véhicules  <B>à</B> moteur.  



  Le ressort<B>à</B> lames selon l'invention est carac  térisé en ce que les lames du ressort sont séparées  par des bandes de polyéthylène poreux imprégné de  lubrifiant.  



  Le dessin annexé représente,<B>à</B> titre      & exemple,     une forme d'exécution de     Fobjct    de l'invention.  



  La     fig.   <B>1</B> est une vue en coupe transversale d'un  ressort<B>à</B>     la-mes   <B>;</B>  la     fig.    2 est une vue en coupe longitudinale  d'un fragment du ressort, suivant la ligne     A-A    de la  <B>f</B>     ig.   <B>3,</B> et  la     fig.   <B>3</B> est une vue en coupe transversale du  ressort.  



  Abstraction faite des feuilles intercalaires en  polyéthylène poreux, qui seront décrites ci-après, le  ressort<B>à</B> lames est du type classique et comporte  un certain nombre de lames de ressort<B>1.</B> Ces lames  sont séparées les unes des autres par des bandes<B>3</B>  de polyéthylène     microporeux    de haute densité impré  gné du lubrifiant connu sous le nom<B>e</B>     Vyon   <B> .</B>  



  L'imprégnation de la matière plastique poreuse  avec du lubrifiant a pour effet de réduire le frotte  ment entre les lames et favorise     l'élimination#    du  grincement des ressorts. Le polyéthylène poreux im  prégné de lubrifiant agit également comme agent  d'amortissement vis-à-vis des vibrations transmises  par l'intermédiaire du système<B>de</B> ressorts.  



  Les bandes<B>3</B> présentent chacune un profil en  auge<B>,</B> les lames sont logées dans les auges, dont les  parois empêchent le déplacement des bandes.    Les lames sont assemblées au voisinage<B>de</B> leurs  extrémités, où il<B>y</B> a seulement quatre     la-mes,   <B>à</B> l'aide  d'un étrier<B>5,</B> qui entoure ces lames.     L76trier    est fixé  <B>à</B> la lame inférieure par un rivet<B>7</B> et :est espacé de  la lame supérieure par une pièce<B>11</B> en polyéthylène  poreux     (fig.    2 et<B>3).</B> La pièce<B>11</B>     es-t    pourvue d'une  rainure<B>13,</B> dans laquelle sont logées les extrémités  supérieures<B>15</B> de l'étrier. La rainure<B>13</B> empêche  ainsi les déplacements de la pièce<B>11.</B>



  <B> Leaf </B> Spring The present invention relates <B> to </B> a <B> </B> leaf spring, which is particularly suitable for <B> motor </B> vehicles.



  The <B> leaf </B> spring according to the invention is characterized in that the leaves of the spring are separated by strips of porous polyethylene impregnated with lubricant.



  The accompanying drawing shows, <B> by </B> title & example, an embodiment of the object of the invention.



  Fig. <B> 1 </B> is a cross-sectional view of a spring <B> at </B> the-mes <B>; </B> in fig. 2 is a longitudinal sectional view of a fragment of the spring, taken along line A-A of <B> f </B> ig. <B> 3, </B> and fig. <B> 3 </B> is a cross-sectional view of the spring.



  Apart from the porous polyethylene interleaves, which will be described below, the <B> </B> leaf spring is of the conventional type and comprises a number of <B> 1 leaf springs. </B> These The blades are separated from each other by strips of high density microporous polyethylene <B> 3 </B> impregnated with the lubricant known as <B> e </B> Vyon <B>. </B>



  Impregnation of the porous plastic material with lubricant has the effect of reducing the friction between the blades and aids the elimination of the squeaking of the springs. The porous polyethylene impregnated with lubricant also acts as a damping agent against vibrations transmitted through the <B> </B> spring system.



  The bands <B> 3 </B> each have a trough profile <B>, </B> the slats are housed in the troughs, the walls of which prevent the bands from moving. The boards are assembled near their ends, <B> there </B> only four leaves, <B> with </B> using a stirrup < B> 5, </B> which surrounds these blades. The caliper is fixed <B> to </B> the lower blade by a rivet <B> 7 </B> and: is spaced from the upper blade by a piece <B> 11 </B> of porous polyethylene (fig. 2 and <B> 3). </B> The part <B> 11 </B> is provided with a groove <B> 13, </B> in which the upper ends are housed <B> 15 </B> of the caliper. The <B> 13 </B> groove thus prevents movement of the part <B> 11. </B>
