Description

       

  Suspension de cylindres hydrauliques de freinage, en particulier pour véhicules de chemin de fer.

  
Dans le cas de freins hydrauliques, en particulier

  
 <EMI ID=1.1> 

  
 <EMI ID=2.1> 

  
posé de disposer le cylindre de freinage de façon permettant le coulissement dans la direction de l'axe mais pour le reste de façon souple sur le sabot de freinage. Cette fixation peut

  
 <EMI ID=3.1> 

  
transmet des chocs par l'intermédiaire des sabots de frein

  
au piston de pression et qu'alors naturellement le cylindre fixe est détaché.

  
La présente invention évite ces inconvénients.Elle consiste en ce que le piston aotionné hydrauliquëment, portant le sabot de frein, est suspendu à une extrémité élastiquement et à l'autre extrémité est guidé dans le cylindre de pression monté de façon à pouvoir tourner à son extrémité libre. On obtient ainsi que les chocs exercés,par la roue sur le sabot de frein sont supportés par la suspension élastique du sabot

  Suspension of hydraulic brake cylinders, in particular for railway vehicles.

  
In the case of hydraulic brakes, in particular

  
 <EMI ID = 1.1>

  
 <EMI ID = 2.1>

  
posed to arrange the brake cylinder so as to allow sliding in the direction of the axis but for the rest in a flexible manner on the brake shoe. This attachment can

  
 <EMI ID = 3.1>

  
transmits shocks through the brake shoes

  
to the pressure piston and then naturally the fixed cylinder is detached.

  
The present invention avoids these drawbacks. It consists in that the hydraulically actuated piston, carrying the brake shoe, is suspended at one end elastically and at the other end is guided in the pressure cylinder mounted so as to be able to rotate at its own. free end. It is thus obtained that the shocks exerted by the wheel on the brake shoe are supported by the elastic suspension of the shoe.
