Description

SYSTEME DE FREINAGE D'UN VEHICULE  BRAKING SYSTEM OF A VEHICLE
L'invention se rapporte à un système de freinage d'un véhicule. Généralement un tel système comprend une pédale de frein située au niveau des pieds du conducteur et émergeant dans un espace libre placé à l'avant du siège conducteur, ainsi qu'un contacteur destiné à allumer les feux stop lorsque ladite pédale est enfoncée pour assurer une phase de freinage. Bien qu'un système de freinage selon l'invention soit particulièrement adapté à un véhicule automobile, il peut également être monté sur tout type de véhicule terrestre doté de roues. L'invention se rapporte plus spécialement à un système de freinage protégé. The invention relates to a braking system of a vehicle. Generally such a system comprises a brake pedal located at the driver's feet and emerging in a free space at the front of the driver's seat, and a switch for switching on the brake lights when said pedal is depressed to ensure a braking phase. Although a braking system according to the invention is particularly suitable for a motor vehicle, it can also be mounted on any type of land vehicle with wheels. The invention relates more specifically to a protected braking system.
Le contacteur permettant d'allumer les feux stop à l'arrière du véhicule pour signaler une phase de freinage, est généralement placé au-dessus de la pédale de frein. Or, il n'est pas rare qu'un conducteur désirant attraper un objet dans la boite à gants ou dans un rangement de la portière du passager, percute par inadvertance ledit contacteur avec son pied, en se penchant sur son siège. Le contacteur est alors endommagé, et ne peut plus être utilisé pour allumer les feux stop. Ce type d'événement engendre, par conséquent, des situations de danger en phase de roulage, dont les conséquences peuvent être dramatiques. The switch to turn on the brake lights at the rear of the vehicle to signal a braking phase, is usually placed above the brake pedal. However, it is not uncommon for a driver wishing to catch an object in the glove box or in a storage of the passenger door, inadvertently struck said contactor with his foot, leaning on his seat. The switch is damaged and can no longer be used to turn on the brake lights. This type of event therefore generates dangerous situations during the driving phase, the consequences of which can be dramatic.
En se référant à la figure 1, une solution qui est couramment retenue pour protéger le contacteur 1, consiste à fixer un écran 2 d'interposition sur un support de pédalier 3 dans lequel est montée en rotation la pédale de frein 4, pour empêcher le pied 5 du conducteur de venir percuter ledit contacteur 1 et l'endommager. Ce type d'écran est souvent fixé de façon systématique dans le véhicule et très tôt dans la chaîne de fabrication dudit véhicule, pour pouvoir accéder à son lieu d'implantation sur celui-ci. Cette fixation est irréversible. Or, il existe certains types de véhicule pour lesquelles la présence d'un écran de protection ne s'impose pas, lorsque par exemple, le contacteur est déjà protégé par une autre pièce ou lorsqu'il est dans une position sensiblement verticale et ne craint pas d'être endommagé par le pied du conducteur. Dans ce cas, la présence d'un écran de protection est inutile et a tendance à alourdir et encombrer inutilement le véhicule. Referring to Figure 1, a solution that is commonly adopted to protect the contactor 1, is to fix a display 2 of interposition on a bottom bracket 3 in which is mounted in rotation the brake pedal 4, to prevent the foot 5 of the driver to hit said contactor 1 and damage it. This type of screen is often set systematically in the vehicle and very early in the production line of said vehicle, to be able to access its location on it. This fixation is irreversible. However, there are certain types of vehicle for which the presence of a protective screen is not required, when for example, the switch is already protected by another part or when it is in a substantially vertical position and feared not to be damaged by the driver's foot. In in this case, the presence of a protective screen is unnecessary and tends to weigh down and unnecessarily clutter the vehicle.
Les systèmes de freinage selon l'invention mettent en œuvre un écran de protection pouvant être implanté à tout moment sur une chaîne de fabrication d'un véhicule, en fonction d'un besoin réel de protection du contacteur. The braking systems according to the invention implement a protective screen that can be installed at any time on a production line of a vehicle, according to a real need for protection of the contactor.
L'invention a pour objet un système de freinage d'un véhicule comprenant un support de pédalier, une pédale de frein et un contacteur fixé audit support et destiné à assurer l'allumage des feux stop lorsque ladite pédale est enfoncée pour assurer le freinage du véhicule. The invention relates to a vehicle braking system comprising a bottom bracket, a brake pedal and a contactor fixed to said support and intended to ensure the ignition of the brake lights when said pedal is depressed to ensure the braking of the vehicle. vehicle.
La principale caractéristique d'un système de freinage selon l'invention, est qu'il comprend un élément de protection dudit contacteur, apte à venir se fixer de façon autonome sur ledit support, au moyen d'un système d'attache rapide, ledit élément étant placé sur ledit support de manière à s'interposer entre le contacteur et le pied du conducteur. De cette manière, l'élément de protection du contacteur peut être implanté à n'importe quelle étape de la chaîne de fabrication d'un véhicule pour répondre à un besoin particulier et réel de protection du contacteur. Cela peut, par exemple, être le cas sur un modèle particulier de véhicule appartenant à une plateforme commune. L'expression « de façon autonome » signifie que l'élément de protection peut venir se fixer dans le véhicule, sans avoir à faire subir audit véhicule ou à son procédé de fabrication une quelconque modification. Il vient juste s'ajouter aux autres pièces déjà présentes. Préférentiellement, le système d'attache rapide ne nécessite pas l'utilisation d'un outil particulier, et s'effectue au moyen d'une simple manipulation et sans effort soutenu. L'élément de protection peut, soit venir se fixer directement sur le support, soit venir s'arrimer à une pièce d'interface, elle-même fixée audit support. L'élément de protection peut être représenté par tout type d'objet rigide ayant une bonne résistance mécanique. Cet élément peut également revêtir toute forme, l'essentiel étant qu'il serve de butée d'arrêt au pied du conducteur afin qu'il ne vienne pas percuter le contacteur, et qu'il ne soit pas trop encombrant. Avantageusement, un système de freinage selon l'invention comprend une embase fixée au support de pédalier, l'élément de protection venant s'arrimer sur ladite embase. De cette manière, il est plus aisé de concevoir des moyens de fixation sur une embase indépendante que sur un support de pédalier, lesdits moyens étant aptes à coopérer avec des moyens de fixation complémentaires de l'élément de protection. L'embase est préférentiellement constituée par une pièce de faible épaisseur et qui est donc peu encombrante. The main characteristic of a braking system according to the invention is that it comprises a protection element of said contactor, adapted to be fixed autonomously on said support, by means of a quick coupling system, said element being placed on said support so as to be interposed between the switch and the driver's foot. In this way, the protection element of the contactor can be implanted at any stage of the production line of a vehicle to meet a particular need and real protection of the contactor. This may, for example, be the case on a particular model of vehicle belonging to a common platform. The expression "independently" means that the protective element can be fixed in the vehicle, without having to subject to said vehicle or its manufacturing process any modification. It just adds to the other pieces already present. Preferably, the quick hitch system does not require the use of a particular tool, and is carried out by means of a simple manipulation and without sustained effort. The protection element can either be fixed directly on the support or come to dock with an interface part, itself attached to said support. The protective element can be represented by any type of rigid object having good mechanical strength. This element can also take any form, the main thing is that it serves as a stop at the foot of the driver so that it does not hit the contactor, and it is not too bulky. Advantageously, a braking system according to the invention comprises a base fixed to the bottom bracket support, the protection element coming to rest on said base. In this way, it is easier to design fastening means on an independent base than on a bottom bracket, said means being adapted to cooperate with complementary fixing means of the protection element. The base is preferably constituted by a thin piece and which is therefore compact.
De façon préférentielle, l'embase possède une ouverture et est placée autour du contacteur de manière à ce que le contacteur passe à travers ladite ouverture. Il s'agit d'une configuration compacte pour laquelle l'embase ne déborde que modérément autour du contacteur. Preferably, the base has an opening and is placed around the contactor so that the contactor passes through said opening. This is a compact configuration for which the base protrudes only moderately around the contactor.
Selon un mode de réalisation préféré d'un système de freinage selon l'invention, l'élément de protection vient se fixer dans l'embase par encliquetage. Selon un autre mode de réalisation préféré d'un système de freinage selon l'invention, l'élément de protection vient se fixer dans l'embase par un dispositif de liaison de type baïonnette. According to a preferred embodiment of a braking system according to the invention, the protection element is fixed in the base by snapping. According to another preferred embodiment of a braking system according to the invention, the protection element is fixed in the base by a bayonet type connection device.
Préférentiellement, l'élément de protection est en plastique. Il participe ainsi à l'allégement du véhicule, tout en assurant efficacement sa fonction de butée grâce à une bonne résistance mécanique. Preferably, the protection element is made of plastic. It thus contributes to the lightening of the vehicle, while effectively providing its stop function thanks to good mechanical strength.
De façon avantageuse, l'élément de protection est un écran de faible épaisseur. Avantageusement, cet écran s'étend sur toute la longueur du contacteur. Advantageously, the protection element is a thin screen. Advantageously, this screen extends over the entire length of the contactor.
De façon préférentielle, l'écran de protection est incurvé autour du contacteur. Ainsi, ledit écran enveloppe étroitement le contacteur en n'offrant aucune possibilité pour le pied du conducteur de venir impacter directement le contacteur. L'invention a pour deuxième objet un kit de protection pour la mise en œuvre d'un système de freinage selon l'invention . Preferably, the protection screen is curved around the contactor. Thus, said screen tightly envelops the contactor by not offering any possibility for the driver's foot to directly impact the contactor. The second object of the invention is a protection kit for implementing a braking system according to the invention.
La principale caractéristique d'un kit de protection selon l'invention, est qu'il comprend un élément de protection d'un contacteur et une embase, ledit élément de protection étant conçu pour venir se fixer sur ladite embase au moyen d'un système d'attache rapide. Avec un tel kit, il est possible de fixer un élément de protection du contacteur, à n'importe quel stade de la chaîne de fabrication du véhicule, car cette fixation s'effectue de façon autonome, c'est-à-dire sans interactions avec les autres pièces déjà présentes dans ledit véhicule. Ce montage s'effectue simplement et rapidement, sans outil et sans effort particulier. The main characteristic of a protection kit according to the invention is that it comprises a protection element of a contactor and a base, said protection element being designed to be fixed on said base by means of a system. fast attachment. With such a kit, it is possible to fix a protective element of the contactor, at any stage of the vehicle production line, because this attachment is carried out autonomously, that is to say without interactions with the other parts already present in said vehicle. This assembly is done simply and quickly, without tools and without special effort.
Avantageusement, un kit de protection selon l'invention comprend des moyens de fixation de l'embase sur le support de pédalier. Ces moyens de fixation peuvent par exemple être constitués par un jeu de vis. Les systèmes de freinage selon l'invention présentent l'avantage d'être souples, en offrant la possibilité d'être implantés rapidement et facilement lorsqu'un besoin réel de protection du contacteur est détecté sur un véhicule. Ils ont de plus l'avantage de pouvoir être implantés facilement et rapidement sans l'aide d'un outil spécifique et sans manipulations contraignantes. On donne ci-après, une description détaillée d'un mode de réalisation préféré d'un système de freinage et d'un kit de protection selon l'invention, en se référant aux figures 1 à 4. Advantageously, a protection kit according to the invention comprises means for fixing the base on the bottom bracket. These fixing means may for example be constituted by a set of screws. The braking systems according to the invention have the advantage of being flexible, offering the possibility of being implanted quickly and easily when a real need for contactor protection is detected on a vehicle. They also have the advantage of being implanted easily and quickly without the aid of a specific tool and without restrictive manipulations. The following is a detailed description of a preferred embodiment of a braking system and a protection kit according to the invention, with reference to FIGS. 1 to 4.

FIG. 3 is a front view of a base of a braking system according to the invention, - Figure 4 is a perspective view of a protective screen of a braking system according to the invention.
La figure 1 a déjà été décrite. Figure 1 has already been described.
En se référant à la figure 2, un système de freinage 10 selon l'invention comprend un support de pédalier 3, une pédale 4 de frein et un contacteur 1 fixé audit support 3 et destiné à assurer l'allumage des feux stop lorsque ladite pédale 4 est enfoncée pour assurer le freinage du véhicule. Ledit système de freinage 10 comprend en outre une embase 6 et un écran de protection 7 destiné à protéger le contacteur 1 contre un coup de pied intempestif du conducteur. En effet, en se penchant sur son siège pour attraper un objet dans la boite à gant ou dans un rangement de la portière du passager, le conducteur va faire machinalement remonter son pied 5, qui peut venir choquer ledit contacteur 1. Comme le contacteur 1 est un objet sensible, il va aussitôt se détériorer et altérer la fonction de freinage du véhicule. L'écran 7, qui est placé entre le pied 5 du conducteur et le contacteur 1, va servir de butée d'arrêt au pied 5 pour l'empêcher de venir percuter ledit contacteur 1. Referring to Figure 2, a braking system 10 according to the invention comprises a bottom bracket 3, a brake pedal 4 and a contactor 1 fixed to said support 3 and intended to ensure the ignition of the stop lamps when said pedal 4 is depressed to brake the vehicle. Said braking system 10 further comprises a base 6 and a protective screen 7 for protecting the contactor 1 against an inadvertent kick of the driver. Indeed, by leaning over his seat to catch an object in the glove box or in a storage of the passenger door, the driver will mechanically raise his foot 5, which can come to shock said contactor 1. As the contactor 1 is a sensitive object, it will immediately deteriorate and alter the braking function of the vehicle. The screen 7, which is placed between the foot 5 of the driver and the contactor 1, will act as a stop stop to the foot 5 to prevent it from striking said contactor 1.
En se référant à la figure 3, l'embase 6 est assimilable à une plaque de plastique de faible épaisseur, sensiblement carrée et dotée d'une ouverture 8 centrale et circulaire. Cette embase 6 possède également trois ouvertures 9 secondaires, disposées autour de l'ouverture centrale 8 et équidistantes du centre de ladite ouverture centrale 9. Deux ouvertures secondaires 9 se retrouvent ainsi dans deux positions diamétralement opposées par rapport à l'ouverture centrale 8, la troisième ouverture secondaire 9 étant placée sur un axe passant par le milieu de l'axe joignant les deux ouvertures secondaires 9 diamétralement opposées, et qui perpendiculaire audit axe. Referring to Figure 3, the base 6 is similar to a thin plastic plate, substantially square and having a central opening 8 and circular. This base 6 also has three secondary openings 9 arranged around the central opening 8 and equidistant from the center of said central opening 9. Two secondary openings 9 are thus found in two diametrically opposed positions with respect to the central opening 8, the third secondary opening 9 being placed on an axis passing through the middle of the axis joining the two diametrically opposite secondary openings 9, and perpendicular to said axis.
Le contacteur 1 possède un corps cylindrique allongé dont le diamètre est inférieur à celui de l'ouverture centrale 8 de l'embase 6. The contactor 1 has an elongated cylindrical body whose diameter is smaller than that of the central opening 8 of the base 6.
En se référant à la figure 4, l'écran de protection 7 est en plastique et est assimilable à une paroi 11 hémicylindrique de faible épaisseur. Cette paroi 11 possède à l'une de ses extrémités, au niveau de l'un de ses bords 12 recourbés, trois ergots 13 émergeant longitudinalement dudit bord 12. Autrement dit, ces trois ergots 13 saillent dudit bord 12 selon un axe longitudinal de ladite paroi 11. En se référant à la figure 2, l'embase 6 est fixée au support de pédalierReferring to FIG. 4, the protective screen 7 is made of plastic and is comparable to a thin-walled hemi-cylindrical wall 11. This wall 11 has at one of its ends, at one of its curved edges 12, three lugs 13 emerging longitudinally from said edge 12. In other words, these three lugs 13 project from said edge 12 along a longitudinal axis of said wall 11 Referring to Figure 2, the base 6 is attached to the bottom bracket
3 par vissage, dans une position pour laquelle le corps du contacteur 1 passe à travers l'ouverture centrale 8 de ladite embase 6, et pour laquelle plus de la moitié dudit corps saille de ladite embase 6.
