Description
La présente invention concerne un outil de prise de mesure permettantThe present invention relates to a measuring tool enabling
d'obtenir l'épaisseur d'un disque de frein automobile sans démontage d'aucune pièce du véhicule et en particulier des roues. to obtain the thickness of an automobile brake disc without dismantling any part of the vehicle and in particular the wheels.
Nombre de garagistes,au dire des fabricants de système de freins, ne changeraient pas les disques de freins lors du remplacement des plaquettes de frein bien que la cote minimale du disque soit atteinte voire dépassée. En général ils ne possèdent pas l'outil adéquat pour prendre la mesure rapidement et en présence du client. L'utilisation d'un pied à coulisse ou d'un micromètre impose le démontage de la roue. Leur lecture et leur utilisation ne sont pas aisees. Many garage owners, according to the brake system manufacturers, would not change the brake discs when replacing the brake pads even though the minimum disc rating was reached or exceeded. In general, they do not have the right tool to take measurements quickly and in the presence of the client. The use of a caliper or a micrometer requires disassembly of the wheel. Their reading and their use are not easy.
Lors du contrôle technique automobile obligatoire,la cote de ces disques n'est pas vérifiée non plus faute d'outil adapté, seul un contrôle visuel est opéré et ne peut certifier le bon état des disques, pièces essentielles au freinage. During the mandatory vehicle inspection, the rating of these discs is not checked either for lack of a suitable tool, only a visual check is made and can not certify the good condition of the discs, essential parts for braking.
L'invention qui concerne un outil de mesure permet de pallier à cette difficulté sur la plupart des véhicules. Cet outil permet par son ergonomie d'être aisément positionné sur le disque de frein du véhicule en passant au travers de la jante de la roue, si celle ci est ajourée, ou par le coté intérieur de la roue. L'utilisateur en actionnant l'outil va pincer le disque de frein en plusieurs points de son rayon sans être faussé ou gêné par l'épaulement caractéristique sur la circonférence du disque de frein et sans descendre au dessous de la surface d'appui des plaquettes de frein. L'outil gardant en mémoire la mesure la plus faible, l'utilisateur peut le retirer et pratiquer la lecture sur le cadran prévu a cette effet. The invention relates to a measurement tool makes it possible to overcome this difficulty on most vehicles. This tool allows its ergonomics to be easily positioned on the brake disc of the vehicle passing through the rim of the wheel, if it is perforated, or by the inner side of the wheel. The user by operating the tool will pinch the brake disc at several points of its radius without being distorted or obstructed by the characteristic shoulder on the circumference of the brake disc and without descending below the bearing surface of the pads of brake. The tool keeping in memory the weakest measurement, the user can remove it and practice reading on the dial provided for this purpose.
Cette opération simple et rapide permettra au garagiste d'indiquer immédiatement à son client l'état des disques, ou au 30 contrôleur technique d'en vérifier la conformité. This simple and fast operation will allow the garage owner to immediately inform his client of the condition of the discs, or the technical controller to verify their conformity.
L'outil comporte un corps de forme cylindrique sur lequel se trouve un compteur sur son coté et il est prolongé d'une tige rigide, solidaire, en forme d'étrier d'un déport axial de 40 millimètres et un retour de 8 millimètres se terminant en pointe de contact. The tool comprises a cylindrical body on which is a counter on its side and is extended by a rigid rod, integral, stirrup-shaped an axial offset of 40 millimeters and a return of 8 millimeters is ending in contact tip.
Le corps est traversé dans son centre par une tige mobile rectangulaire dont une des faces est dentée sur sa longueur et au 2/3 de sa largeur. Les dents sont centrées sur la tige et ne dépassent pas du bord de la tige. La tige a une pointe de contact d'un coté et un bouton d'appui de l'autre. La pointe de la tige mobile est face à la pointe de l'étrier. Une butée fixée sur la tige mobile coté pointe limite sa course. Un ressort se positionne sur la tige mobile entre le bouton d'appui et le corps. Le ressort est fixé d'un coté sur le corps et de l'autre sur le bouton d'appui. Sa longueur et son élasticité font que lorsque l'outil est au repos la tige mobile est maintenue dans une position où la distance entre le corps et la butée est égale ou supérieure à la distance entre la pointe de la tige mobile et la pointe de l'étrier. Cette distance est d'environ 4.5 centimètres. The body is crossed in its center by a rectangular movable rod, one side is toothed along its length and 2/3 of its width. The teeth are centered on the stem and do not protrude from the edge of the stem. The stem has a contact tip on one side and a push button on the other. The tip of the movable rod is facing the tip of the stirrup. A stop fixed on the movable rod on the tip side limits its course. A spring is positioned on the movable rod between the support button and the body. The spring is fixed on one side on the body and on the other on the button of support. Its length and elasticity mean that when the tool is at rest the movable rod is held in a position where the distance between the body and the abutment is equal to or greater than the distance between the tip of the movable rod and the tip of the rod. 'stirrup. This distance is about 4.5 centimeters.
La tige mobile, entraîne dans son mouvement, via ses dents un ensemble pignon -axe positionné à l'intérieur du corps. Le ressort au repos maintient la pointe de la tige mobile à une distance déterminée de la pointe de l'étrier mesureur équivalente à une rotation de 350 du pignon. L'axe maintient le pignon en contact avec la tige mobile. L'axe est guidé par des alésages dans le corps.L'axe traverse d'un seul coté le corps par le centre du compteur. L'axe est plié à 90" à son extrémité dans le compteur. Le compteur de forme circulaire dont l'embase est formée par le corps, est constitué d'un feutre qui est fixé au fond, sur lequel repose un disque gradué. Le disque gradué est maintenu en place et centré par un guide épaulé emboîté dans le corps. Le disque est freiné en rotation par le guide épaulé et le feutre mais il n'est pas bloqué. Le disque gradué est entraîné en rotation par contact de l'axe sur un plot fixe. L'axe du pignon denté n'est pas solidaire du plot du disque gradué. Le compteur est fermé par un capot transparent. Le capot transparent est emboîté sur l'embase du compteur et peut tourner sur lui même. Un repère est gravé sur le haut du capot transparent face au disque gradué. The movable rod causes in its movement, via its teeth, a pinion-axis assembly positioned inside the body. The idle spring maintains the tip of the movable rod at a determined distance from the tip of the caliper measurement equivalent to a rotation of 350 of the pinion. The axle keeps the pinion in contact with the moving rod. The axis is guided by bores in the body. The axis crosses on one side the body by the center of the meter. The axis is bent 90 "at its end in the meter.The circular counter whose base is formed by the body, consists of a felt which is fixed at the bottom, on which rests a graduated disc. graduated disc is held in place and centered by a shouldered guide fitted into the body, the disc is braked in rotation by the shouldered guide and the felt, but it is not locked in. The graduated disc is rotated by contact with the The axis of the toothed pinion is not fixed to the stud of the graduated disk.The meter is closed by a transparent cover.The transparent cover is nested on the base of the meter and can turn on itself. A mark is engraved on the top of the transparent cover facing the graduated disc.
Selon un mode de réalisation non représenté il peut être 30 rajouté sur le corps un dispositif de blocage de la tige mobile l'empêchant de reculer au delà de sa position repos. According to an embodiment not shown it can be added to the body a locking device of the movable rod preventing it from moving back beyond its rest position.
La mise en oeuvre de l'outil se fait comme suit: Saisir le corps entre l'index et le majeur et appliquer une poussée sur le bouton d'appui de la tige de manière à comprimer le ressort jusqu' au contact de la pointe de la tige mobile et de celle de l'étrier. Maintenir ce contact et de l'autre main étalonner le compteur en amenant par rotation le repère du capot transparent face au zéro du disque gradué .Relâcher le bouton d'appui et tirer la tige mobile en arrière jusqu'au contact de sa butée sur le corps. Ce mouvement permet d'emmener le disque gradué de sa position zéro à sa position maximum de prise de cote, environ 4.5 centimètres.Relâcher la tige.L'outil est prêt à prendre une mesure. The implementation of the tool is as follows: Grasp the body between the index finger and the middle finger and apply a push on the support button of the rod so as to compress the spring until contact with the tip of the movable rod and that of the stirrup. Hold this contact and with the other hand calibrate the counter by rotating the mark of the transparent cover towards the zero of the graduated disc. Release the support button and pull the movable rod backwards until the stop reaches the stop. body. This movement takes the graduated disc from its zero position to its maximum stance position, about 4.5 centimeters. Releasing the rod.The tool is ready to take a measurement.
Positionner l'outil sur le disque de frein. Porter au contact du disque la pointe de 1' étrier d'un coté et par une pression du pouce, pincer le disque en emmenant en contact, sur son autre face, la pointe de la tige mobile. Position the tool on the brake disc. Wear the tip of the stirrup on one side with the thumb of the disc and pinch the disc, bringing the tip of the movable rod into contact with its other side.
Relâcher légèrement la pression et répéter l'opération 4 a 5 fois sur lo plusieurs points du rayon du disque pour obtenir l'épaisseur la plus juste en cas d'usure irrégulière de sa surface. Slowly release the pressure and repeat the operation 4 to 5 times over several points of the radius of the disc to obtain the most accurate thickness in case of irregular wear of its surface.
En effet,le disque gradué n'étant pas solidaire de l'axe qui l'entraîne va garder en mémoire la cote minimale trouvée sur le disque. Le feutre placé entre le corps et le disque gradué évite toute rotation inopportune du disque gradué en cas de choc sur l'outil durant l'opération de mesure. Indeed, the graduated disc is not integral with the axis that drives it will keep in memory the minimum score found on the disc. The felt placed between the body and the graduated disc avoids any untimely rotation of the graduated disc in the event of impact on the tool during the measuring operation.
Relâcher le bouton d'appui et retirer l'outil. La lecture de la cote est maintenant possible sur le disque gradué au travers du capot transparent via son repère. Release the button and remove the tool. The reading of the dimension is now possible on the graduated disc through the transparent cover via its mark.
