Description

  

  Joint universel    La présente invention se rapporte<B>à</B> un joint uni  versel comportant deux fourches engagées respecti  vement dans deux gorges méridiennes perpendicu  laires d'une rotule centrale.  



  En général, dans des joints de ce type, on prévoit  une encoche sur une ou deux fourches pour permet  tre le montage du joint. L'existence de cette encoche  sur une fourche constitue un point faible pour la  résistance<B>à</B> la torsion, aux chocs et en marche alter  née.  



  La présente invention a pour objet un joint uni  versel qui est exempt de cet inconvénient.  



  Le joint universel, objet de l'invention, est ca  ractérisé en ce que chaque fourche comporte un ar  ceau     d7engagement    ininterrompu, tandis que des  moyens sont prévus pour     renclenchement    des extré  mités de chaque arceau dans une gorge, en sorte que  l'étendue d'engagement dépasse d'un demi-cercle  pour empêcher un démontage intempestif du joint.  



  Une forme     dexécution   <B>de</B> l'objet de l'invention  sera décrite,<B>à</B> titre d'exemple, en référence au dessin  annexé dans lequel<B>:</B>  La     fig.   <B>1</B> est une vue en élévation frontale du  joint universel<B>;</B>  la     fig.    2 est une vue en élévation latérale suivant  les flèches     II-II    de la     fig.   <B>1 ;</B>  la     fig.   <B>3</B> est une vue analogue<B>à</B> la     fig.   <B>1</B> mais  montre le joint en élévation éclatée<B>;

  </B>  la     fig.    4 est une vue en coupe transversale sui  vant la ligne     IV-IV    de la     fig.    2<B>, -</B>  la     fig.   <B>5</B> est une vue de la rotule centrale suivant  les flèches     V-V    de la     fig.   <B>3 ;</B>    les     fig.   <B>6 à</B> 12 illustrent les diverses phases de  montage du joint.  



  Un joint universel comporte     (fig.   <B>1,</B> 2, 4 et 12)  deux fourches<B>1</B> et 2, engagées respectivement dans  deux gorges méridiennes perpendiculaires<B>3</B> et 4  d'une rotule centrale<B>5.</B>  



  Chaque fourche<B>1,</B> 2     (fig.   <B>3)</B> comporte un arceau  d'engagement ininterrompu<B>6</B> dont l'étendue dépasse  un demi-cercle avant montage du joint. Les extrémi  tés de chaque arceau<B>6</B> sont constituées par des fa  cettes convergentes<B>7.</B>  



  Une cuvette oblongue<B>8</B> est ménagée dans les  gorges<B>3</B> et 4 pour l'enclenchement des extrémités<B>7</B>  de chaque arceau<B>6</B> dans une gorge<B>3</B> ou 4.  



  La cuvette<B>8</B>     (fig.   <B>5)</B> présente deux zones<B>9</B> et<B>10</B>  destinées<B>à</B> coopérer respectivement avec les fourches  <B>1</B> et 2 pour l'enclenchement successif de celles-ci. La  zone<B>9</B>     (fig.   <B>5)</B> est placée<B>à</B> un croisement des deux  gorges<B>3</B> et 4, tandis que la zone<B>10</B> s'étend     latérale-          lement   <B>à</B> partir de la zone<B>9</B> dans la gorge 4.  



  Le montage du joint s'effectue<B>de</B> la manière sui  vante.  



  On présente     (fig.   <B>6)</B> la fourche<B>1</B> en regard de la  rotule<B>5</B> et l'on engage une des extrémités<B>7 de</B> la  fourche<B>1</B>     (fig.   <B>7)</B> dans la zone<B>9</B> de la cuvette<B>8.</B>  Puis l'on fait tourner la fourche<B>1</B> dans le sens de la  flèche F<B>de</B> la     fig.   <B>7</B> en prenant appui par l'extré  mité<B>7</B> dans la zone<B>9</B> de, la cuvette<B>8,</B> ce qui permet  d'enclencher l'arceau<B>6</B> de la fourche<B>1</B> dans la gorge  <B>3</B>     (fig.   <B>8).</B>  



  Puis l'on fait tourner la rotule<B>5</B> dans<B>le</B> sens de  la flèche FI de la     fig.   <B>3.</B> Cette rotation est guidée par  l'engagement de la gorge<B>3</B> sur l'arceau<B>6</B> de la four  che<B>1.</B> On amène ainsi la rotule<B>5</B> dans la position  <B>de</B> la     fig.   <B>9</B> où la cuvette<B>8</B> se trouve dans l'axe<B>de</B>      la fourche<B>1,</B> la zone<B>10 de</B> la cuvette<B>8</B> étant démas  quée latéralement.  



  Dans cette zone<B>10</B> de la cuvette<B>8,</B> en engage  une extrémité<B>7</B> de la fourche 2     (fig.   <B>10)</B> puis l'on  exerce une action sur la fourche 2 par rapport<B>à</B> la  fourche<B>1</B> dans le sens de la flèche     F2        (fig.   <B>11)</B> qui  tend<B>à</B> enclencher l'arceau<B>6</B> de la fourche 2 dans  la gorge 4. Lorsque cet enclenchement est effectué, le  joint est définitivement monté     (fig.    12) et ne peut se  défaire intempestivement.  



  On peut toutefois, si besoin est, démonter vo  lontairement le joint, par le processus inverse de ce  lui qui vient     d7être    décrit.  



  On notera que le joint décrit est facile<B>à</B> fabri  quer et est très robuste grâce aux surfaces étendues  de contact.  



  Ce joint présente une haute résistance dans des  conditions difficiles de fonctionnement, notamment  une haute résistance en marche alternée, aux chocs  et aux vibrations. Son angle maximum de travail<B>A</B>       (fig.   <B>1)</B> est grand et est de l'ordre<B>de</B> 450. En outre  le joint comporte des réserves de graissage impor  tantes.



  Universal joint The present invention relates <B> to </B> a universal joint comprising two forks engaged respectively in two perpendicular meridian grooves of a central ball joint.



  In general, in joints of this type, a notch is provided on one or two forks to enable the joint to be fitted. The existence of this notch on a fork constitutes a weak point for the resistance to <B> to </B> torsion, to shocks and to alternate operation.



  The present invention relates to a universal joint which is free from this drawback.



  The universal joint, object of the invention, is characterized in that each fork has an uninterrupted engagement hoop, while means are provided for engaging the ends of each hoop in a groove, so that the extent of 'engagement protrudes by a semicircle to prevent inadvertent removal of the seal.



  An embodiment <B> of </B> the object of the invention will be described, <B> to </B> by way of example, with reference to the appended drawing in which <B>: </B> The fig. <B> 1 </B> is a front elevational view of the universal joint <B>; </B> in fig. 2 is a side elevational view along arrows II-II of FIG. <B> 1; </B> fig. <B> 3 </B> is a view similar to <B> to </B> FIG. <B> 1 </B> but shows the joint in exploded elevation <B>;

  </B> fig. 4 is a cross-sectional view along the line IV-IV of FIG. 2 <B>, - </B> fig. <B> 5 </B> is a view of the central patella along the arrows V-V in fig. <B> 3; </B> fig. <B> 6 to </B> 12 illustrate the various gasket assembly phases.



  A universal joint comprises (fig. <B> 1, </B> 2, 4 and 12) two forks <B> 1 </B> and 2, respectively engaged in two perpendicular meridian grooves <B> 3 </B> and 4 with a central <B> 5. </B>



  Each fork <B> 1, </B> 2 (fig. <B> 3) </B> has an uninterrupted engagement hoop <B> 6 </B> whose extent exceeds a semicircle before assembly of the seal. The ends of each arch <B> 6 </B> are formed by converging facets <B> 7. </B>



  An oblong bowl <B> 8 </B> is provided in the grooves <B> 3 </B> and 4 for engaging the ends <B> 7 </B> of each arch <B> 6 </ B > in a groove <B> 3 </B> or 4.



  Pit <B> 8 </B> (fig. <B> 5) </B> has two zones <B> 9 </B> and <B> 10 </B> intended for <B> to </ B > cooperate respectively with the forks <B> 1 </B> and 2 for the successive engagement of these. Zone <B> 9 </B> (fig. <B> 5) </B> is placed <B> at </B> a crossing of the two gorges <B> 3 </B> and 4, while zone <B> 10 </B> extends laterally <B> to </B> from zone <B> 9 </B> in throat 4.



  The gasket is fitted <B> in </B> as follows.



  We present (fig. <B> 6) </B> the fork <B> 1 </B> opposite the ball joint <B> 5 </B> and we engage one of the ends <B> 7 of </B> the fork <B> 1 </B> (fig. <B> 7) </B> in zone <B> 9 </B> of the bowl <B> 8. </B> Then the fork <B> 1 </B> is rotated in the direction of arrow F <B> of </B> in fig. <B> 7 </B> by resting by the end <B> 7 </B> in zone <B> 9 </B> of, the basin <B> 8, </B> which allows you to engage the arch <B> 6 </B> of the fork <B> 1 </B> in the groove <B> 3 </B> (fig. <B> 8). </B>



  Then the ball joint <B> 5 </B> is rotated in <B> the </B> direction of the arrow FI in fig. <B> 3. </B> This rotation is guided by the engagement of the groove <B> 3 </B> on the arch <B> 6 </B> of the fork che <B> 1. < / B> The ball joint <B> 5 </B> is thus brought into position <B> of </B> in fig. <B> 9 </B> where the bowl <B> 8 </B> is in the axis <B> of </B> the fork <B> 1, </B> the zone <B> 10 of </B> the bowl <B> 8 </B> being unmasked laterally.



  In this zone <B> 10 </B> of the bowl <B> 8, </B> engages one end <B> 7 </B> of the fork 2 (fig. <B> 10) </ B > then an action is exerted on the fork 2 relative to <B> to </B> the fork <B> 1 </B> in the direction of the arrow F2 (fig. <B> 11) </ B > which tends <B> to </B> engage the arch <B> 6 </B> of the fork 2 in the groove 4. When this engagement is carried out, the seal is permanently fitted (fig. 12) and does not can come undone.



  However, if necessary, the seal can be removed voluntarily, by the reverse process of what has just been described.



  It will be noted that the described gasket is easy <B> to </B> to manufacture and is very robust thanks to the large contact surfaces.



  This seal exhibits high resistance under difficult operating conditions, including high resistance to alternating operation, shock and vibration. Its maximum working angle <B> A </B> (fig. <B> 1) </B> is large and is of the order of <B> of </B> 450. In addition, the joint has reserves lubrication.
