Description

  

  Roue avec     freùi   <B>à</B> disque         Uinvention    a pour objet une roue avec frein<B>à</B>  disque, pour véhicule, comprenant au moins un  cylindre, dans lequel coulisse un piston, pour     l'ac-          tionnement    du frein au moyen d'un fluide sous pres  sion, air ou huile. Cette roue pourrait être une roue  d'avions, par exemple.  



  Selon les réalisations connues de telles roues,  l'ensemble constitué par le disque ou le groupe des  disques, solidaires en rotation de la roue<B>à</B> freiner, et  les patins de frein     déplaçables        axialement    par le  cylindre hydraulique, est logé<B>à</B> l'intérieur de la roue,  sous la jante, tandis que ledit cylindre est extérieur  <B>à</B> celles-ci et est porté par une branche du support  fixe de frein, également extérieure au corps de roue  et<B>à</B> la jante.  



  Or, il a été constaté que, dans ces conditions,  le ou les disques se refroidissent mal<B>;</B> il en résulte  un échauffement anormal de la jante et, cas échéant,  d'un pneumatique, ce qui entraîne des risques<B>de</B>  détérioration,<B>à</B> la fois des roues en alliage léger et  des chambres<B>à</B> air ou des talons du pneumatique.  



  La présente invention a pour but d'éviter ces  inconvénients et<B>à</B> cet effet la roue avec frein<B>à</B> disque  est caractérisée selon cette invention, par au moins  un cylindre dans lequel coulisse un piston, pour     Pac-          tionnement    du frein au moyen d'un fluide sous pres  sion<B>;</B> caractérisée par au moins un disque porté par  une collerette latérale<B>à</B> la jante de la roue, qui l'en  traîne en rotation, tout en lui permettant un déplace  ment axial<B>;

  </B> et par au moins deux patins     porte-garni-          tures    de friction, ne participant pas<B>à</B> la rotation de  la roue, dont un, celui qui est le plus éloigné du  cylindre     d'actionnement    du frein, prend appui sur un  élément du véhicule, ledit cylindre étant logé entre  le voile de la roue, sa jante et son moyeu.    <B>-</B> Ainsi, la source d'échauffement se trouve repor  tée dans une zone extérieure au profil<B>de</B> la jante et  cas échéant d'un pneumatique.  



  Le dessin annexé représente,<B>à</B> titre d'exemple,  une forme d'exécution de la roue selon l'invention.  La     fig.   <B>1</B> représente, en coupe, la roue<B>à</B> frein       monodisque.     



  Les     fig.    2 et<B>3</B> sont des vues partielles, respec  tivement de face et par-dessus, montrant un exemple  de     solidarisation    en rotation de la collerette, donc de  la roue, et du disque.  



  Les     fig.    4 et<B>5</B> sont des vues correspondantes  pour une variante d'exécution.  



  Sur ces figures<B>:</B>  <B>1</B> désigne le corps de roue<B>;</B> 2, la jante<B>; 3,</B> le  pneumatique<B>;</B> 4, le support fixe de frein, réduit<B>à</B>  une seule branche largement engagée sous la jante<B>;</B>  <B>-</B> cette branche porte les cylindres hydrauliques ou  pneumatiques,     5a-5b.     



  Dans chacun de ceux-ci est mobile le piston<B>6,</B>  qui attaque un patin,<B>7,</B> portant une garniture de  frein<B>8,</B> vis-à-vis de laquelle se présente le disque<B>9,</B>  (ou la série des disques, s'il s'agit d'un frein     multi-          disques).    Le disque<B>9</B> se trouve<B>à</B> l'aplomb d'une  collerette,<B>10,</B> saillant latéralement de la jante et il  est entraîné en rotation par cette collerette formée  de tenons venus de la jante qui     coopùrent    avec des  saillants prévus<B>à</B> la périphérie du disque et laissant  au disque une liberté de translation axiale.  



  Vis-à-vis de la face extérieure du disque se pré  sente une seconde garniture,<B>11,</B> portée par un  patin 12.      Dans la forme     d7exécution    représentant une roue  d'avion, ce patin 12, situé<B>à</B> l'opposé du cylindre de  frein,     s    'appuie contre la structure,<B>13,</B> de     Patterris-          seur.   <B>De</B> même, pour tout autre véhicule, ledit patin  s'appuiera sur la structure fixe de celui-ci.  



  La disposition représentée permet de gagner suf  fisamment de place     axialement    pour ne pas aug  menter la longueur<B>d</B> représentant l'encombrement  total: jambe de     l'atterrisseur    plus pneumatique.  



  Dans un cas comme dans l'autre, la branche  extérieure habituelle du support de frein se trouve  supprimée.  



  On voit que la ventilation du disque de frein  s'effectue dans des conditions beaucoup plus favo  rables (flèches     f)    que dans le cas des freins<B>à</B> disque  classiques<B>:</B> l'air échauffé par     raction    de freinage  n'est pas, comme dans ceux-ci, concentré sous la  jante et,     eautre    part, les effets de     conductibilité        ther-          inique    intéressant la collerette, sont pratiquement dis  sipés grâce<B>à</B> l'aération de cette dernière, largement  balayée par l'air libre.  



  Les     fig.   <B>2-3</B> et 4-5 représentent deux variantes  assurant l'entraînement en rotation du disque,<B>9,</B> par  la jante, 2, tout en conservant au premier sa liberté  de translation axiale.    Dans le cas des     fig.   <B>2-3,</B> seulement un espace sur  deux entre tenons consécutifs est occupé par un sail  lant du disque, les autres,<B>16,</B> restant vides.    Dans la réalisation selon les     fig.    4-5, préférable  <B>à</B> la précédente, tous les espaces entre tenons sont  occupés par un saillant du disque.



  Wheel with <B> </B> disc brake The invention relates to a wheel with <B> </B> disc brake, for a vehicle, comprising at least one cylinder, in which a piston slides, for ac- brake operation by means of pressurized fluid, air or oil. This wheel could be an aircraft wheel, for example.



  According to the known embodiments of such wheels, the assembly formed by the disc or the group of discs, integral in rotation with the wheel <B> to </B> to be braked, and the brake pads movable axially by the hydraulic cylinder, is housed <B> inside </B> the inside of the wheel, under the rim, while said cylinder is outside <B> to </B> these and is carried by a branch of the fixed brake support, also outside the wheel body and <B> to </B> the rim.



  However, it has been observed that, under these conditions, the disc or discs cool poorly <B>; </B> this results in abnormal heating of the rim and, where applicable, of a tire, which causes risks <B> of </B> deterioration, <B> to </B> both the light alloy wheels and the <B> air </B> chambers or the tire beads.



  The object of the present invention is to avoid these drawbacks and <B> to </B> this effect the wheel with <B> disk </B> brake is characterized according to this invention, by at least one cylinder in which slides a piston, for brake actuation by means of a pressurized fluid <B>; </B> characterized by at least one disc carried by a lateral flange <B> at </B> the rim of the wheel, which drags it in rotation, while allowing it an axial displacement <B>;

  </B> and by at least two friction lining-bearing pads, not participating <B> in </B> the rotation of the wheel, one of which is the one furthest from the actuating cylinder of the brake, bears on an element of the vehicle, said cylinder being housed between the web of the wheel, its rim and its hub. <B> - </B> Thus, the heat source is located in a zone outside the profile <B> of </B> the rim and, where applicable, of a tire.



  The appended drawing represents, <B> to </B> by way of example, an embodiment of the wheel according to the invention. Fig. <B> 1 </B> represents, in section, the wheel <B> with </B> single-disc brake.



  Figs. 2 and <B> 3 </B> are partial views, respectively from the front and from above, showing an example of joining in rotation of the collar, therefore of the wheel, and of the disc.



  Figs. 4 and <B> 5 </B> are corresponding views for an execution variant.



  In these figures <B>: </B> <B> 1 </B> designates the wheel body <B>; </B> 2, the rim <B>; 3, </B> the tire <B>; </B> 4, the fixed brake support, reduced <B> to </B> a single branch widely engaged under the rim <B>; </B> < B> - </B> this branch carries the hydraulic or pneumatic cylinders, 5a-5b.



  In each of these is movable the piston <B> 6, </B> which attacks a pad, <B> 7, </B> carrying a brake lining <B> 8, </B> opposite -screw of which the disc <B> 9, </B> is presented (or the series of discs, if it is a multi-disc brake). The disc <B> 9 </B> is located <B> at </B> a flange, <B> 10, </B> projecting laterally from the rim and it is driven in rotation by this flange formed of tenons from the rim which cooperate with projections provided <B> at </B> the periphery of the disc and leaving the disc freedom of axial translation.



  Opposite the outer face of the disc is a second lining, <B> 11, </B> carried by a pad 12. In the embodiment representing an airplane wheel, this pad 12, located < B> at </B> opposite the brake cylinder, rests against the structure, <B> 13, </B> of Patterris- seur. <B> Likewise, for any other vehicle, the said pad will be supported on the fixed structure thereof.



  The arrangement shown makes it possible to save sufficient space axially so as not to increase the length <B> d </B> representing the total bulk: more pneumatic landing gear leg.



  In either case, the usual outer branch of the brake support is omitted.



  It can be seen that the brake disc is ventilated under much more favorable conditions (arrows f) than in the case of conventional <B> </B> disc brakes <B>: </B> air heated by the braking action is not, as in these, concentrated under the rim and, on the other hand, the thermal conductivity effects affecting the collar, are practically dissipated thanks to <B> to </B> l ventilation of the latter, largely swept by the open air.



  Figs. <B> 2-3 </B> and 4-5 represent two variants ensuring the rotational drive of the disc, <B> 9, </B> by the rim, 2, while retaining the first its freedom of translation axial. In the case of fig. <B> 2-3, </B> only every second space between consecutive studs is occupied by a disk sail, the others, <B> 16, </B> remaining empty. In the embodiment according to FIGS. 4-5, preferable <B> to </B> the previous one, all the spaces between tenons are occupied by a protrusion of the disc.
