Abstract
Description
La présente invention concerne les instruments de frei- nage permettent le ralentissement ou l'arrêt d'un organe robile entraîne par le mouvement circulaire d'un ou de plusieurs axes. The present invention relates to braking instruments allowing the slowing or stopping of a movable member driven by the circular movement of one or more axes.
Dons les diffrrer,ts dispositifs de ce genre, on note divers procédés que l'on peut regrouper en deux grandes familles
le frein à tambour
le frein à disque
Dans la prémière famille, on note un nombre très impor- tant de procédés de fonctionnement, ainsi qu'une diversité de point- techniques qui ont fait évoluer sensiblem.ent cette technique. Le principe de base en reste neanrroins le même.Let’s differ them, such devices, we note various processes that can be grouped into two large families
the drum brake
the disc brake
In the first family, there is a very large number of operating procedures, as well as a diversity of technical points which have made this technique evolve sensibly. The basic principle remains the same.
Le terbour est forme d'un cylindre de hauteur faible par rap- port au diamètre, solidaire de l'organe mobile et contre le quel viennent frotter des garnitures montées sur des segments de freins, aux-mêmes portés par des supports solidaires d'un organe fixe par rapport @ l'axe rotatif.The terbour is in the form of a cylinder of low height compared to the diameter, integral with the movable member and against which come to rub linings mounted on brake shoes, in themselves carried by supports integral with a member fixed relative to the rotary axis.
Le principaux handicaps de c type de frein sont la mauvoise répartition des pressions sur toute la surface de frottent des garnitures ce qui entraîne une usure irrégulière et la néccesité de réglages fréquents, les garnitures traveillant enfermées dans le cylindre le manque de ventillation et de refroidissement entraîne des déformations du plan intérieur (bands de freinage) du tambour, et les dilatations occasionnées par l'échauffement, l'éloignement des surfaces frottantes. The main handicaps of this type of brake are the poor distribution of pressures over the entire surface of the friction of the linings which leads to irregular wear and the need for frequent adjustments, the linings trapping trapped in the cylinder the lack of ventilation and cooling causes deformations of the internal plane (braking bands) of the drum, and expansions caused by heating, distance from the friction surfaces.
Dans la deuxième famille, on ncte la aussi une très grande diversite de procédés de fonctionnement autour de deux grands principes 1' Le frein È disque enfermé ru rependu, n'offrant pas d'avantage per rarport au frein é disque liure et ayant l'inconvénient d'une plus mauvaise évacuation des calories 2V Le frein à disque libre
Son principe an opposition au frein c tambour est d'exercer des forces de serrages dans le sens axial, c'est-à-dire parallèle à l'axe de rotation, le disque est solidaire de l'arbre et le merrage sur les deux f-ces du disque s'effectue Far un sabot solidaire d'un organe fixe et -uni de deux patins venant incer le disque sur un secteur limité.In the second family, there is also a very wide variety of operating methods around two main principles 1 'The enclosed disc brake ru split, offering no per rarport advantage to the disc brake disc and having the disadvantage of a worse evacuation of calories 2V The free disc brake
Its principle in opposition to the drum brake is to exert clamping forces in the axial direction, that is to say parallel to the axis of rotation, the disc is integral with the shaft and the wetting on both f - these discs are carried out Far a shoe secured to a fixed member and - provided with two pads which incer the disc on a limited sector.
Le dispositif de freinage selon l'invention que nous appelons frein conique permet de corriger les inconvénients des principes de freinage précités en apportant en plus un surcroît de puissance 3UX freins existants. The braking device according to the invention which we call conical brake makes it possible to correct the drawbacks of the abovementioned braking principles by bringing in addition an increase in power to 3UX existing brakes.
En effet, tout sn travaillant lui aussi à l'air libre, tout comme le frein à disque, assurant ainsi une parfaite ventilation et un refroidissement maximum, le cône offre l'avant-ge de porter sur 360 et donc d'éviter tout effort de réac- tion sur las roulements de moyeux, d'éliminer les vibrations grâce au repprochement des surfaces de contact avec l'axe de rotation, et d'augmenter considérablement la surface de frottenant t donc d'augmenter la puissance de freinage tout en di minuant l'usure et les contrôles frÉquents. Il est à noter que 1- portes de contect et donc la puissance du frein peut tre modifiés en jouant sur 1 hauteur ou sur la pente du cens. Indeed, any sn also working in the open air, like the disc brake, thus ensuring perfect ventilation and maximum cooling, the cone offers the advantage of wearing on 360 and therefore avoiding any effort of reaction on the hub bearings, eliminating vibrations by bringing the contact surfaces closer to the axis of rotation, and considerably increasing the friction surface t therefore increasing the braking power while di reducing wear and frequent checks. It should be noted that 1- contect doors and therefore the brake power can be modified by playing on 1 height or on the slope of the cens.
Le frein conique selon l'invention est compos d'un cône "plein" appelé cône mobile, solidaire de l'organe mobile et donc axe de rotation est confondu avec l'axe mobile et d'un cône "vide" appelé ene de pression rigoureusement symetrique quant à la pente et s'emboîtent selon le principe mâle-femelle. The conical brake according to the invention is composed of a "full" cone called a movable cone, integral with the movable member and therefore the axis of rotation coincides with the movable axis and of an "empty" cone called a pressure cone. rigorously symmetrical with regard to the slope and fit together according to the male-female principle.
Le cens de pression se déplacé dans le sens axial à l'in- trieur d'un corps cylindrique solidaire d'un organe fixe, comportant des rainures de guidage empêchant le mouvement circulaire du cône sur l'axe. The pressure censor moves in the axial direction inside a cylindrical body integral with a fixed member, having guide grooves preventing the circular movement of the cone on the axis.
Ce cône de pression psut répondre à la demande de freinage par se pression sur le cône mobile et ce soit pr un système hydraulique avec des cylindres récepteurs et des pistons, scit par un système conique avec levier, câble, ou autres. This pressure cone can meet the braking demand by pressing on the movable cone and it is pr a hydraulic system with receiving cylinders and pistons, scit by a conical system with lever, cable, or others.
I1 est È noter que dans le cas du frein conique le rappel hydraulique OU mécanique du cône de pression n'est pas obligatoire, la force centrifuge du mouvement circulaire du cône mobile empêchent tout contact impromptu. It should be noted that in the case of the conical brake, the hydraulic OR mechanical return of the pressure cone is not compulsory, the centrifugal force of the circular movement of the mobile cone prevents any impromptu contact.
Le cône mobile tout comme le frein à disque, peut outre carté de la roue, ou, comme dans le principe général du frein È tambour, porteur ds la roue. The movable cone, like the disc brake, can, apart from the wheel housing, or, as in the general principle of the drum brake, support the wheel.

FIG. 2 showing the pressure cone from the front, in two parts to allow on the one hand, quick disassembly and on the other hand, easier relining.
Tel qu'il est représenté, le cône mobile 1, solidaire de l'axe mobile 2, est enveloppé par le cône de pression 3, contenu dans la cylindre 4, et pouvant se déplacer axialement dans les rainures de guidage 5, lui permettant de rentrer en contact avec le cane mobile 1, st ce, grace à la poussée des pistons 7, se mouvant dans les cylindres récepteurs 8, dont l'étanchétté est assurée par les coupelles 10, la commande du freinage étant transmis par l'arrivée du liquide de frein par la canal 9. As shown, the mobile cone 1, integral with the mobile axis 2, is enveloped by the pressure cone 3, contained in the cylinder 4, and which can move axially in the guide grooves 5, allowing it to come into contact with the movable rod 1, st this, thanks to the thrust of the pistons 7, moving in the receiving cylinders 8, the sealing of which is ensured by the cups 10, the braking command being transmitted by the arrival of the brake fluid through channel 9.
Lors de la mise sou pression du liquide de frein arrivant dans les cylindres récèpteurs 8 les pistons 7, poussent le cône de pression 3, recouvert sur ses pantes de garniture de frein 6, vers la cône mobile 2. La mise en contact des deux cônes entrains la ralentissement puis l'arrêt du cône mobile, le cdns de pression étant retenu dans le sens circulaire par les rainures de guidage 5. During the pressurization of the brake fluid arriving in the receiving cylinders 8 the pistons 7, push the pressure cone 3, covered on its pads with brake lining 6, towards the movable cone 2. The contacting of the two cones cause the mobile cone to slow down and then stop, the pressure cdns being retained in the circular direction by the guide grooves 5.
Le dispositif, objet de l'invention, peut outre utilisé dans tous les cas de freinage d'engin utilisant le mouvement circulaire d'un ou de plusieurs axes et notamment sur tous les engins exigeant un freinage puissant. The device which is the subject of the invention can also be used in all cases of vehicle braking using the circular movement of one or more axes and in particular on all vehicles requiring powerful braking.
De plus, le dispositif suivant l'invention doit permettre d'améliorer considérablement le problème des vibrations. In addition, the device according to the invention must make it possible to considerably improve the problem of vibrations.
Des applications particulièrement intéressantes peuvent être l'utilisation en automobiles et en véhicules lourds et dans des domaines tres divers comme l'industrie, la mécanique l'aviation, etc... Particularly interesting applications can be the use in automobiles and heavy vehicles and in very diverse fields such as industry, mechanics, aviation, etc.
