ser entre les bagues de roulement extérieures une bague intermédiaire .lui sert au guidage-'la ferai des faces radiales, tournées l'une vers l'autre, des corps de roulement.

  
palier de boite d'essieu suivant la présente invention se distingue des formes de réalisation connues par le fait que pour le guidage axial plus complet des corps de roulement,les bagues de roulement extérieures sont appliquées, par leurs cotés tournés en sens opposé, contre des épaulements fixes, tandis que les épaulements se troucant sur les côtés tournés l'un vers l'autre sont formés par des surfaces d'une bague intermédiaire disposée entre les bagues de roulement extérieures

  
On obtien t ainsi cet avantage que lors de l'enlèvement de la boite d'essieu de la bague de roulement intérieure,les corps de roulement sont maintenus en position sans pouvoir bouger et qu'il ne peut se produire un basculement de ces cors qui pourrait provoquer un coincement.

 <EMI ID = 4.1>

  
movible is designed to allow easy removal of the axle box with the bearing bodies and the ex-

simple stage and conversely a simple assembly of the bearing.

  
 <EMI ID = 6.1> <EMI ID = 7.1>

  
ser between the outer rolling rings an intermediate ring .lui serves for guiding-'la will make the radial faces, facing one another, of the rolling bodies.

  
Axle box bearing according to the present invention differs from known embodiments by the fact that for the more complete axial guidance of the rolling bodies, the outer rolling rings are applied, by their sides turned in opposite directions, against fixed shoulders, while the shoulders opening on the sides facing each other are formed by surfaces of an intermediate ring disposed between the outer bearing rings

  
This advantage is thus obtained that when the axle box is removed from the inner rolling ring, the rolling bodies are held in position without being able to move and that there can be no tilting of these cores which could cause jamming.

  
The drawing represents the object of the invention in two exemplary embodiments for electric tram vehicles &#65533;

no shoulder. The rollers are guided axially at these latter points by the front faces of the guide ring 8 so that all the rollers therefore have impeccable axial guidance on both sides * A disc 11 is fixed by means of

  
of three bolts 12 to the journal 2 and thus press the ring

 <EMI ID = 23.1>

  
The rings 6 and 7 and the intermediate ring 8 are driven by the shoulder 17a and the rolling bodies with the cages are also removed and remain in their correct position in the removed housing. The assembly is done by sliding the
