Abstract
L'INVENTION SE RAPPORTE A UN DISPOSITIF DE MESURE INDIRECTE DE L'USURE DES GARNITURES D'EMBRAYAGES DE VEHICULES AUTOMOBILES, DANS LEQUEL UNE TIGE-POUSSOIR 4 APPUYEE CONTRE LA FOURCHETTE DE DEBRAYAGE 5 PRESENTE UN SEGMENT CONIQUE 3, DONT LA POSITION, QUI DEPEND DE L'USURE DE LA GARNITURE D'EMBRAYAGE, EST REPEREE AU MOYEN D'UNE JAUGE 8.THE INVENTION RELATES TO A DEVICE FOR INDIRECT MEASURING OF THE WEAR OF THE CLUTCH LININGS OF MOTOR VEHICLES, IN WHICH A PUSH-ROD 4 PRESSED AGAINST THE CLUTCH FORK 5 HAS A CONICAL SEGMENT 3, WHOSE POSITION, WHICH OF THE CLUTCH LINING WEAR IS IDENTIFIED BY MEANS OF A GAUGE 8.
Description
L'invention se rapporte à un dispositif pour la mesure indirecte deThe invention relates to a device for the indirect measurement of
l'usure des garnitures des embrayages, notamment pour embrayages de véhicules automobiles, comprenant un dispositif d'actionnement d'embrayage qui comprend une tige-poussoir agissant sur une fourchette de débrayaqe et se déplaçant en translation en fonction de la course motrice de la pédale d'embrayage, et qui est muni d'un segment de tige conique pouvant être palpé au moyen d'une jauge dans la région d'une zone de mesure de sorte que, dans la position embrayée de l'embrayage, wear of the clutch linings, in particular for motor vehicle clutches, comprising a clutch actuation device which comprises a push rod acting on a clutch release fork and moving in translation as a function of the driving stroke of the pedal clutch, and which is provided with a segment of conical rod which can be palpated by means of a gauge in the region of a measurement zone so that, in the engaged position of the clutch,
l'extrémité de la fourchette de débrayage côté tige- end of declutching fork on rod side -

ment de l'usure des garnitures, en direction de la tige-poussoir à partir d'une position initiale, et qu'une variation de diamètre constatée par la jauge wear of the linings, in the direction of the push rod from an initial position, and a variation in diameter noted by the gauge
signale l'usure des garnitures de l'embrayage. signals the wear of the clutch linings.
Dans un dispositif de ce genre connu par le brevet en Allemagne Fédérale DE-30 44 746, le segment conique de la tige-poussoir est formé par un manchon In a device of this kind known by the patent in Federal Germany DE-30 44 746, the conical segment of the push rod is formed by a sleeve
conique monté mobile en translation sur la tige- conical mounted movable in translation on the rod-
poussoir et qui coulisse sous l'action d'une butée solidaire du carter, au moment du premier débrayage de l'embrayage, pour prendre une position fixe pusher and which slides under the action of a stop integral with the casing, at the time of the first disengagement of the clutch, to assume a fixed position
qui correspond à la pleine épaisseur des garnitures. which corresponds to the full thickness of the linings.
Etant donné que le manchon conique n'est relié à la tige-poussoir que par une liaison par friction, il n'est pas possible d'exclure avec certitude le risque Since the conical sleeve is only connected to the push rod by a friction connection, it is not possible to exclude with certainty the risk
de voir le manchon changer de position sur la tige- to see the sleeve change position on the rod-
poussoir pendant la durée de service du véhicule Il n'est pas possible d'observer ce processus de l'extérieur de l'embrayage et le résultat est que des mesures d'usure donnent des résultats de mesure erronnés. L'invention vise à éliminer les inconvénients précités et, pour résoudre ce problème, l'invention consiste en ce que le segment conique de la tigepoussoir est constitué par la tige-poussoir elle-même. Grâce à l'invention, on obtient que, lorsque l'embrayage est embrayé, dans un véhicule neuf, ou après le renouvellement des garnitures d'embrayage ou encore après le remplacement de l'embrayage, et indépendamment des tolérances de fabrication et de montage, on peut déterminer la position de départ de la tige-poussoir au moyen de la jauge d'une façon simple par le fait que, lorsque la jauge est appuyée contre le segment conique de la tige-poussoir, on repère sa position relativement à une partie fixe push button during vehicle service life It is not possible to observe this process from outside the clutch and the result is that wear measurements give erroneous measurement results. The invention aims to eliminate the aforementioned drawbacks and, to solve this problem, the invention consists in that the conical segment of the push rod consists of the push rod itself. Thanks to the invention, it is obtained that, when the clutch is engaged, in a new vehicle, or after the renewal of the clutch linings or even after the replacement of the clutch, and independently of the manufacturing and mounting tolerances , the starting position of the push rod can be determined by means of the gauge in a simple manner by the fact that, when the gauge is pressed against the conical segment of the push rod, its position is identified relative to a fixed part
du carter pour former une marque de zéro ou d'origine. of the housing to form a zero or origin mark.
L'usure des garnitures éventuellement constatée ulté- The wear on the linings, if any, found later
rieurement peut alors être mesurée à partir de cette laughter can then be measured from this
marque de zéro.zero mark.
Selon une forme avantageuse de réalisation de l'invention, dans la zone de mesure la jauge peut être disposée à coulissement dans une glissière et encadrer la tige-poussoir, de telle sorte que la jauge reste toujours dans la zone de mesure et qu'on n'ait pas à la conserver séparément La jauge peut être munie d'un arrêtoir, par exemple constitué par des saillies latérales, à l'aide duquel elle est maintenue par conjugaison de formes dans une position According to an advantageous embodiment of the invention, in the measurement zone the gauge can be arranged to slide in a slide and frame the push rod, so that the gauge always remains in the measurement zone and that does not have to keep it separately The gauge can be provided with a retainer, for example constituted by lateral projections, with the help of which it is maintained by conjugation of shapes in a position
déterminée à l'intérieur de sa glissière. determined inside its slide.
