Abstract

The invention relates to a braking device 1, relating to the parking brakes of cars. This device is characterised in that it consists of a compact element, essentially comprising a tensioning element 2 and a drive element 3, mounted facing one another and connected to the parking brakes by means of transmission elements, the drive element 3 being controlled by external means, such that, when the electric, hydraulic, or pneumatic flow to the drive element 3 is cut off, the tensioning element 2 provides sufficient mechanical tension for the parking brake transmission elements, thereby correctly immobilising the car, especially when its engine is stopped, a supply of electrical, hydraulic or pneumatic flow to the drive element 3 unclamping the brakes concerned. The invention relates to cars.

Description

L'invention a trait à un dispositif de freinage se rapportant aux freins de stationnement de voitures. The invention relates to a braking device relating to car parking brakes.

De nos jours,pour immobiliser une voiture en stationnement,le conducteur utilise le frein à main. Nowadays, to stop a parked car, the driver uses the parking brake.

En serrant ce dernier manuellement,on agit sur les freins de stationnement,plus ou moins correctement.By tightening the latter manually, we act on the parking brakes, more or less correctly.

Dans certains cas,on oublie même de le serrer.In some cases, we even forget to tighten it.

Le manque de régularité du serrage du frein à main et de son oubli,peuvent provoquer de très graves accidents.De même,on reproche au système manuel, une utilisation désagréable et pénible pour des personnes ayant peu de force musculaire.The lack of regularity of the tightening of the handbrake and its forgetting, can cause very serious accidents. Similarly, the manual system is criticized for an unpleasant and painful use for people with little muscular strength.

La présente invention a pour but de remédier à ces inconvénients et propose de fournir un dispositif de freinage l,concernant les freins de stationnement de voitures,en assurant un serrage régulier et sans oubli.En effet,l'invention prévoit,qu'à l'arrêt du moteur,les freins sont automatiquement serrés.On peut également adjoindre un système qui desserre seulement les freins de stationnement, lorsque le moteur est en marche et que l'une des vitesses est engagée.Par l'intermédiaire d'une commande,près du volant de la voiture,le conducteur aura la possibilité d'actionner les freins de stationnement.Cela facilitera nettement les manoeuvres de démarrage en côte.De même,l'effort physique à fournir pour commander lesdits freins sera pratiquement nul. The present invention aims to remedy these drawbacks and proposes to provide a braking device, relating to the parking brakes of cars, ensuring a regular tightening and without forgetting. Indeed, the invention provides that 'the engine is stopped, the brakes are automatically tightened.On can also be added a system that only releases the parking brakes, when the engine is running and that one of the speeds is engaged.By order, near the wheel of the car, the driver will be able to actuate the parking brakes. This will greatly facilitate start-up maneuvers. Similarly, the physical effort to provide to control said brakes will be virtually zero.

L'invention sera bien comprise en se référant aux descriptions suivantes,faites à titre d'exemples non limitatifs et aux dessins dans lesquels - la figure 1 est une vue en élévation du dispositif, sans le balancier. The invention will be better understood with reference to the following descriptions, given as non-limiting examples and to the drawings in which - Figure 1 is an elevational view of the device, without the pendulum.

- la figure 2 est une vue de dessus en coupe du dispositif.- Figure 2 is a top view in section of the device.

- la figure 3 est une vue en élévation du dispositif sans le balancier,suivant un autre mode de réalisation. - Figure 3 is an elevational view of the device without the beam, according to another embodiment.

- la figure 4 est une vue de dessus en coupe du dispositif,suivant un autre mode de réalisation.- Figure 4 is a top view in section of the device, according to another embodiment.

On se réfère aux figures 1 et 2
L'élément moteur 3 est un élément électromécanique:soit un électro-aimant travaillant en poussée ou un vérin électrique,qui par manque de courant électrique,fait reculer sa partie active vers son corps, en utilisant éventuellement à cet effet,un ressort ou autre matériel.L'élément moteur 3est solidaire de l'élément tendeur 2 par l'intermédiaire du support de fixation 7,assemblés par des vis du genre 8 ou d'une façon quelconque.Le support 7 est à son tour fixé au chassis ou aux éléments de tôle 9 de la voiture par des boulons 10 et ll.l'élément moteur 3 et l'élément tendeur 2 sont situés face à face l'un de l'autre.Referring to Figures 1 and 2
The motor element 3 is an electromechanical element: either an electromagnet operating in thrust or an electric cylinder, which by lack of electric current, backs its active part towards its body, possibly using for this purpose, a spring or other The motor element 3 is integral with the tensioning element 2 by means of the fixing support 7, assembled by screws of the genus 8 or in any other way. The support 7 is in turn fixed to the frame or 9 of the car by the bolts 10 and 11.The motor element 3 and the tensioning element 2 are located opposite each other.

Lorsque l'élément moteur 3 est mis sous tension électrique,par des moyens extérieurs,la face active 2+ dudit élément pousse la pièce 5,en comprimant le ressort 6
A ce moment,la tige 5 munie d'un disque se déplace dans le trou 22 de la cloche 4 vers ltextérieur du dispositif.Cette action mécanique peut provoquer le déplacementdTunWiancierft2.Ledit balancier 12 est fixé à la tige 5 par une articulation 13.When the motor element 3 is energized by external means, the active face 2+ of said element pushes the workpiece 5, compressing the spring 6
At this moment, the rod 5 provided with a disc moves in the hole 22 of the bell 4 towards the backside of the device.This mechanical action can cause the displacement ofaWiancierft2.This balance 12 is fixed to the rod 5 by a hinge 13.

A chaque extrémité du balancier 12 sont fixées les pièces 14 et 15,dans lesquelles les câbles 20 et 21 sont sertis.Les pièces 14 et 15 sont rendues solidaires du balancier par des écrous 16,17,18 et 19.Les cibles 20 et 21 terminent leur prolongement dans des gaines, aboutissant aux plateaux des roues,pour agir sur les éléments de friction des freins de stationnement.At each end of the balance 12 are fixed the parts 14 and 15, in which the cables 20 and 21 are crimped.The parts 14 and 15 are made integral with the balance by nuts 16, 17, 18 and 19. The targets 20 and 21 terminate their extension in ducts, ending in the wheel trays, to act on the friction elements of the parking brakes.

Ce déplacement précité du balancier 12 provoque le desserrage des freins en question.Lorsque le courant électrique de l'élément moteur 3 est coupé,la partie active 24 dudit élément recule vers son corps et le ressort 6 produit un effet de traction sur les câbles 20 et 21,serrant à leur tour les freins de stationnement.En reculant,la partie active 2+ de l'élément moteur 3 laisse un espace suffisant,afin que la pièce 5 puisse se déplacer librement,sous l'action du ressort 6, dans la cloche 4,en agissant ainsi indirectement et constamment sur les freins en question.This aforementioned displacement of the balance 12 causes the release of the brakes in question.When the electric current of the motor element 3 is cut, the active portion 24 of said element back to its body and the spring 6 produces a traction effect on the cables 20 and 21, in turn tightening the parking brakes.In retreating, the active portion 2+ of the motor element 3 leaves enough space, so that the part 5 can move freely, under the action of the spring 6, in the bell 4, thus acting indirectly and constantly on the brakes in question.

On se réfère aux figures 3 et 4. Referring to Figures 3 and 4.

Suivant un autre mode de réalisation, l'élément moteur 3 est alors un vérin fonctionnant avec un fluide : soit hydraulique ou pneumatique. According to another embodiment, the motor element 3 is then a cylinder operating with a fluid: either hydraulic or pneumatic.

Pour desserrer les freins,on applique une pression sur le fluide à travers le passage 25 de l'élément moteur.To release the brakes, pressure is applied to the fluid through the passage of the motor member.

A ce moment,on applique une pression sur la face 2S, en comprimant le ressort 6.Par cet effet,on desserre les freins de stationnement.Lorsque la pression du fluide tend vers zéro,le ressort 6 agit sur la pièce 5 en serrant par l'intermédiaire d'autres éléments lesdits freins.At this moment, a pressure is applied on the face 2S, by compressing the spring 6.To this effect, the parking brakes are released.When the pressure of the fluid tends towards zero, the spring 6 acts on the part 5 by tightening by through other elements said brakes.

Un autre mode de réalisation prévoit une combinaison d'un levier manuel de commande et dudit dispositif.Ce levier peut être monté en série ou en parallèle avec le dispositif l,dans le but d'savoir une sécurité supplémentaire de ce système de freinage. Another embodiment provides a combination of a manual control lever and said device. This lever can be mounted in series or in parallel with the device 1, for the purpose of knowing additional safety of this braking system.

Ce levier manuel de commande accessible au conducteur, peut comporter une position intermédiaire, permettant - à chaque moment,de serrer ou de desserrer lesqfreins de stationnement,manuellement.This manual control lever accessible to the driver, may include an intermediate position, allowing - at any time, to tighten or loosen the parkingfreques, manually.

Un autre mode d'exécution prévoit la possibilité suivante : que si l'alimentation du fluide électrique ou autre,sous tension ou pression de l'élément moteur 3 est arrêtée,le serrage des freins de st;ation- nement se fasse automatiquement.Ce principe peut être appliqué à l'arrêt du moteur de la voiture,en utilisant soit : la clé de contact en association avec un autre élément,coupant en même temps l'arrivée du fluide ou en utilisant un relais de la voiture. Another embodiment provides the following possibility: that if the power supply of the electric fluid or other, under tension or pressure of the motor element 3 is stopped, the tightening of the staging brakes is done automatically. Principle can be applied to the engine stop of the car, using either: the ignition key in combination with another element, cutting at the same time the arrival of the fluid or using a relay of the car.

Enfin,une autre réalisation consiste à adjoindre un système constitué par divers éléments, empêchant de desserrer les freins de stationnement, si le moteur n'est pas en marche et s'il n'y a pas une vitesse engagée.  Finally, another embodiment consists of adding a system consisting of various elements, preventing the release of the parking brakes, if the engine is not running and if there is no gear engaged.

I1 est possible de réaliser cette sécurité,en utilisant des fins de course électriques ou de vannes commandant le fluide du dispositif 1 ou les divers éléments ensemble. It is possible to achieve this security by using electrical limit switches or valves controlling the fluid of the device 1 or the various elements together.

Bien que l'invention ait été décrite à propos de diverses formes de réalisation particulière, il est bien entendu,qu'elle n > y est nullement limitée et que l'on peut y apporter diverses modifications de formes,de matériaux et de combinaisons de ces divers éléments,sans pour cela s'éloigner du cadre et de l'esprit de l'invention.  Although the invention has been described with respect to various particular embodiments, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations of materials can be made. these various elements, without departing from the framework and the spirit of the invention.
