Abstract

The invention has the effect of braking the snow scooter by itself, in the event of its rider falling off. The braking action is set off by the single fact that the driver and the machine have become separated. This emergency brake also serves as a parking brake when the driver after having stopped moves from the machine. In both cases, it is the detachable cord joining machine and rider together which will actuate the hydraulic slide valve before detaching.

Description

La présente invention a pour objet de stopper le véhicule enThe object of the present invention is to stop the vehicle by

cas de chute accidentelle ou volontaire du conducteur, ou d'être utilisé en tant que frein de parking.  accidental or intentional fall of the driver, or to be used as a parking brake.

Toutes les motoneiges sont freinées par actionnement d'une poignée de frein fixée sur le guidon de la machine. Pour que la machine soit freinée, la poignée doit obligatoirement être  All snowmobiles are braked by actuating a brake handle attached to the handlebars of the machine. For the machine to be braked, the handle must be

actionnée par le conducteur, et verrouillée "fermée" mécanique- ment dans le cas d'usage en frein de parking.  actuated by the driver, and mechanically locked "closed" in the event of use as a parking brake.

A noter, quand cas de fuite d'huile sur le circuit hydraulique  Please note, when there is an oil leak on the hydraulic circuit

de freinage, le freinage normal ou de parking s'en trouverait réduit à néant.  braking, normal or parking braking would be reduced to nothing.

A noter également que le défaut énnoncé ci-dessus ne se produi-  Note also that the above-mentioned defect does not occur.

rait pas si le freinage était commandé par cable, à condition qu'il n'y ait pas de rupture de celui-ci, ou de ses amarres.  not if the braking was controlled by cable, provided that there is no rupture of the latter, or of its moorings.

Disons aussi que toutes les motoneiges sont freinées par un frein situé en amont de la chaîne ou train de pignons d'entraî-  Let's also say that all snowmobiles are braked by a brake located upstream of the chain or chain of sprockets

nement de la chenille, ce qui signifie quand cas de rupture de cet élément la motoneige ne peut plus être freinée.  track, which means when this element breaks, the snowmobile can no longer be braked.

L'invention consiste à freiner directement la motoneige par sa arbre d' chenille, et au niveau de sor-entraînement par un frein monté solidairement sur celui-ci, lequel à l'état de repos se trouve  The invention consists in braking the snowmobile directly by its track shaft, and at the sor-drive level by a brake mounted integrally on the latter, which in the rest state is

en position "freiné" par la seule détente du ressort qui le bloc.  in the "braked" position by the mere relaxation of the spring blocking it.

Fonctionnement de l'inventionHow the invention works

Une poignée hydraulique de freinage ou appelée aussi maître-  A hydraulic brake handle or also called master-

cylindre est fixée au guidon de la machine, envoie de l'huile dans le piston d'ouverture du frein de secours, lorsque celle-ci  cylinder is fixed to the handlebar of the machine, sends oil in the opening piston of the emergency brake, when the latter

est manoeuvrée manuellement de plusieurs pompages.  is manually operated by several pumps.

- 2- Sur la conduite hydraulique reliant poignée hydraulique et piston d'ouverture se trouve un appareil dôté d'un clapet anti-retour30 qui permet au fluide de passer que dans le sens poignée- piston. Cet appareil comprend également un tiroir hydraulique  - 2- On the hydraulic line connecting the hydraulic handle and the opening piston is a device fitted with a non-return valve30 which allows the fluid to pass only in the handle-piston direction. This appliance also includes a hydraulic drawer

de commande complèté d'un cordon non tendu, dont une extrémité est détachable du tiroir et l'autre extrémité accrochée au conducteur.  control complete with a non-stretched cord, one end of which is detachable from the drawer and the other end attached to the conductor.

Pour que le détachement du cordon se fasse après déplacement du tiroir hydraulique jusqu'à la position "tiré", la force néces-  To detach the cord after moving the hydraulic slide valve to the "pulled" position, the force required

saire de détachement du cordon est supérieure à la force de déplacement du tiroir.  the detachment of the cord is greater than the displacement force of the drawer.

Ce tiroir hydraulique a deux fonctions: La première, lorsqu'il est en position "poussé", le clapet anti- retour exerce sa fonction, c'est à dire donner la possibilité  This hydraulic drawer has two functions: The first, when it is in the "pushed" position, the non-return valve performs its function, ie giving the possibility

d'ouvrir hydrauliquement le frein de secours et comprimer son ressort en pompant par la poignée hydraulique jusqu'à ne plus pouvoir, ce qui signifie que le frein de secours est débloqué.  hydraulically open the emergency brake and compress its spring by pumping through the hydraulic handle until no longer able, which means that the emergency brake is released.

Deuxième fonction. Lorsque le tiroir hydraulique est en position "tiré", il annule la fonction d'anti-retour. Le fluide peut passer dans le sens piston-poignée hydraulique. Dès cet instant,  Second function. When the hydraulic slide valve is in the "pulled out" position, it cancels the non-return function. Fluid can flow in the piston-hydraulic handle direction. From this moment,

le ressort de freinage préalablement comprimé se détend pour bloquer le frein de secours, et en même temps repousser le pis-50 ton qui tenait le frein ouvert, et par conséquence, repousser aussi le fluide dans la poignée hydraulique.  the previously compressed brake spring relaxes to block the emergency brake, and at the same time push back the pis-50 ton which held the brake open, and consequently push back the fluid in the hydraulic handle as well.

Cette deuxième fonction s'établira d'elle même, lorsqu'en cas -de chute du conducteur, ou du fait qu'il quitte volontairement la machine, le cordon accroché au conducteur va d'abord se tendre,  This second function will be established by itself, when in the event of a fall of the driver, or the fact that he voluntarily leaves the machine, the cord hung on the driver will first be tightened,

ensuite actionner le tiroir hydraulique jusqu'à position "tiré", puis se détacher de celui-ci.  then activate the hydraulic slide valve to the "pulled" position, then detach from it.
