Description

  

  Dispositif de fixation d'une roue     auxiliaire    sur une roue de véhicule    La présente invention a pour objet un dispositif  de fixation d'une roue auxiliaire sur une roue de  véhicule.  



  Ce dispositif est caractérisé par des     chevilles          portées    par l'une au moins des deux roues et s'en  gageant dans. des brides,     portées    par l'autre, les che  villes étant     maintenues    en engagement dans les bri  des par un dispositif de verrouillage.  



       Le    dessin annexé représente, à titre d'exemple,  une forme d'exécution du dispositif selon l'invention.  La     fig.    1 est une vue en élévation d'une roue  d'un véhicule agricole     munie    de brides du     dispositif     de     cette    forme d'exécution.  



  La     fig.    2 en est une vue en coupe selon     II-II     de la     fig.    1.  



  La     fig.    3 est une vue en élévation d'une roue  auxiliaire, munie d'un bandage en caoutchouc, et  des chevilles du     dispositif    de fixation, et destinée à  être     montée    sur la roue représentée à la     fig.    1.  



  La     fig.    4 en est une vue en coupe selon IV-IV  de la     fig.    3.  



  Pour fixer chacune des roues auxiliaires sur les  roues du véhicule, on     munit    lesdites roues 1 du  véhicule de deux traverses 3 disposées de part et  d'autre de leur moyeu, lesdites traverses. présentant  chacune une paire de brides 4 faisant saillie sur la  face externe des roues. 1, lesdites brides 4 de l'une  des traverses étant, d'autre     part,        réunies    par une  entretoise 3' présentant dans sa partie     médiane    un  orifice 5, dont le but sera décrit plus loin.

   Les roues       auxiliaires    7 représentées à la     fig.    3 sont     également     munies de traverses 8 disposées de     part    et d'autre    de leur moyeu, lesdites traverses 8 présentent le  même     écartement    que les traverses 3 des roues 1  et sont munies,     chacune    d'une paire de chevilles 9  destinées à s'engager dans les brides 4 des roues 1.

    L'une des traverses est, d'autre     part,    munie d'une  tige 8' disposée entre ces chevilles 9 et présentant  dans sa partie médiane une partie     filetée    10 destinée  à s'engager     dans        l'orifice    5 de l'entretoise 3' de la  roue 1. Les roues 7 sont, d'autre part, munies d'un  bandage en caoutchouc naturel ou synthétique.  



  Le montage des roues 7 sur les roues 1 peut       s'effectuer,    de façon très, simple: la roue 1 se trou  vant dans la position représentée à la     fig.    1, on intro  duit les chevilles 9 de la roue 7 dans ses brides 4 et  l'on déplace le véhicule en avant ou en arrière d'un  demi-tour de roue. A ce moment, les chevilles 9 sont  engagées à fond dans les brides 4 et la roue 1 repo  sant sur les traverses 8 de la roue 7 ne touche plus  le sol.  



  La partie filetée 10 de la tige est également en  gagée à fond dans l'orifice 5 de l'entretoise 3' et sera  munie d'un écrou 11 afin, que la roue 1 ne retombe  pas sur le sol lorsqu'elle se retrouvera dans la posi  tion représentée à la     fig.    1. Pour démonter la roue       auxiliaire    7, il     suffira        d'effectuer    une opération  inverse de celle qui vient d'être     décrite.  



  Device for fixing an auxiliary wheel on a vehicle wheel The present invention relates to a device for fixing an auxiliary wheel on a vehicle wheel.



  This device is characterized by pegs carried by at least one of the two wheels and engaging them in. flanges, carried by the other, the che towns being held in engagement in the bri des by a locking device.



       The appended drawing represents, by way of example, an embodiment of the device according to the invention. Fig. 1 is an elevational view of a wheel of an agricultural vehicle provided with flanges of the device of this embodiment.



  Fig. 2 is a sectional view along II-II of FIG. 1.



  Fig. 3 is an elevational view of an auxiliary wheel, provided with a rubber tire, and the pins of the fixing device, and intended to be mounted on the wheel shown in FIG. 1.



  Fig. 4 is a sectional view along IV-IV of FIG. 3.



  In order to fix each of the auxiliary wheels on the wheels of the vehicle, said wheels 1 of the vehicle are provided with two cross members 3 arranged on either side of their hub, said cross members. each having a pair of flanges 4 projecting from the outer face of the wheels. 1, said flanges 4 of one of the sleepers being, on the other hand, joined by a spacer 3 'having in its middle part an orifice 5, the purpose of which will be described later.

   The auxiliary wheels 7 shown in FIG. 3 are also provided with sleepers 8 arranged on either side of their hub, said sleepers 8 have the same spacing as the sleepers 3 of the wheels 1 and are each provided with a pair of pegs 9 intended to engage in the flanges 4 of the wheels 1.

    One of the crosspieces is, on the other hand, provided with a rod 8 'arranged between these pins 9 and having in its middle part a threaded part 10 intended to engage in the orifice 5 of the spacer 3' of the wheel 1. The wheels 7 are, on the other hand, provided with a natural or synthetic rubber tire.



  The assembly of the wheels 7 on the wheels 1 can be carried out very simply: the wheel 1 is in the position shown in FIG. 1, the pegs 9 of the wheel 7 are introduced into its flanges 4 and the vehicle is moved forward or backward by half a turn of the wheel. At this time, the pegs 9 are fully engaged in the flanges 4 and the wheel 1 resting on the cross members 8 of the wheel 7 no longer touches the ground.



  The threaded part 10 of the rod is also fully engaged in the orifice 5 of the spacer 3 'and will be provided with a nut 11 so that the wheel 1 does not fall to the ground when it finds itself in the position shown in fig. 1. To remove the auxiliary wheel 7, it will suffice to perform an operation in reverse to that which has just been described.
