Abstract
Description
La présente invention a pour objet un dispositif de réglage de la chasse d'un véhicule, notamment d'un kart.The present invention relates to a device for adjusting the hunting of a vehicle, in particular a kart.
On sait que les véhicules ont des réglages particuliers en fonction de la conception de leur châssis et que les performances, notamment de tenue de route, dépendent essentiellement de ces réglages.We know that vehicles have specific settings depending on the design of their chassis and that performance, including handling, depends mainly on these settings.
Il en est ainsi de la chasse qui correspond à l'inclinaison du support de la roue directrice par rapport à la verticale, dans le sens de déplacement.This is the case with hunting, which corresponds to the inclination of the support of the steering wheel with respect to the vertical, in the direction of movement.
Dans le cas du kart, l'élément de suspension est inexistant puisque ces véhicules, par le règlement même imposé par la Fédération, en sont dépourvus, néanmoins les réglages restent très importants..In the case of the kart, the suspension element is nonexistent since these vehicles, by the same regulations imposed by the Federation, do not, however the settings are very important.
Le châssis comprend un triangle inférieur fixe, solidaire de ce châssis, un triangle supérieur articulé par rapport au châssis, et un bras de direction interposé entre ces deux triangles dont les extrémités sont munies de rotules.The chassis comprises a fixed lower triangle, integral with this chassis, an upper triangle articulated with respect to the chassis, and a steering arm interposed between these two triangles, the ends of which are provided with ball joints.
De façon connue, le bras de direction est relié au moyen d'une tringle à la colonne de direction.In known manner, the steering arm is connected by means of a rod to the steering column.
Le triangle supérieur est monté à rotation autour d'un axe orienté sensiblement parallèlement à la direction de déplacement du véhicule.The upper triangle is mounted for rotation about an axis oriented substantially parallel to the direction of movement of the vehicle.
Cet axe est monté entre les deux oreilles d'une chape et il comprend des filetages à ses extrémités de façon à pouvoir déplacer le triangle entre ces deux oreilles ce qui conduit au réglage de la chasse.This axis is mounted between the two ears of a yoke and it includes threads at its ends so as to be able to move the triangle between these two ears which leads to the adjustment of the flush.
Ce type de réglage reste délicat à effectuer et il est difficilement reproductible. De plus, dans certaines conditions de course ou d'essai, il faut pouvoir modifier très rapidement le réglage de la chasse tout en conservant la précision nécessaire à ce type de réglage. This type of adjustment remains difficult to perform and it is difficult to reproduce. In addition, under certain race or test conditions, it must be possible to modify the hunting setting very quickly while retaining the precision necessary for this type of setting.
La présente invention a pour objet un dispositif de réglage de la chasse d'un véhicule qui est simple, qui est parfaitement reproductible, qui est précis, qui est d'un prix de revient peu élevé, qui ntengen- dre que très peu de modifications du véhicule, qui, pour certaines variantes, est très rapide à effectuer et qui n'altère pas la fiabilité du véhicule.The subject of the present invention is a device for adjusting the hunting of a vehicle which is simple, which is perfectly reproducible, which is precise, which has a low cost price, which results in very few modifications. of the vehicle, which, for some variants, is very quick to perform and which does not affect the reliability of the vehicle.
A cet effet, le dispositif de réglage de la chasse d'un véhicule avec une suspension éventuelle, notamment d'un kart comprenant un châssis avec un triangle supérieur support de rotule de direction, monté pivotant par rapport à ce châssis autour d'un axe de pivotement sensiblement parallèle à la direction de déplacement du véhicule caractérisé en ce que le triangle supérieur comprend des moyens de réglage en translation suivant l'axe de pivotement
Selon une autre caractéristique de l'invention, le triangle est monté pivotant dans une chape autour d'un axe amovible, des cales étant interposées entre les oreilles de la chape et la base du triangle, autour de l'axe.To this end, the device for adjusting the hunting of a vehicle with a possible suspension, in particular of a kart comprising a chassis with an upper triangle, support for a ball joint, pivotally mounted relative to this chassis around an axis. pivot substantially parallel to the direction of movement of the vehicle characterized in that the upper triangle comprises means for adjusting in translation along the pivot axis
According to another characteristic of the invention, the triangle is pivotally mounted in a yoke around a removable axis, wedges being interposed between the ears of the yoke and the base of the triangle, around the axis.
Selon une variante, les cales sont des rondelles fendues radialement.Alternatively, the shims are radially split washers.
Selon un mode de réalisation préférentiel de l'invention, les rondelles comprennent un logement axial et un prolongement axial en saillie prévus pour coo pérer lorsque deux rondelles sont juxtaposées.According to a preferred embodiment of the invention, the washers comprise an axial housing and an axial protruding extension provided to co-operate when two washers are juxtaposed.
De façon à faciliter les réglages, les cales ont une épaisseur donnée qui permet un réglage de l'angle par pas de valeur fixe, par exemple un degré.In order to facilitate adjustments, the shims have a given thickness which allows adjustment of the angle in steps of a fixed value, for example a degree.
Les réglages de la chasse selon l'invention couvrent une plage de 50 à 15 de façon à couvrir la quasi totalité des véhicules. The hunting settings according to the invention cover a range of 50 to 15 so as to cover almost all of the vehicles.
L'invention est décrite ci-après selon un mode de réalisation particulier et une variante, ceci en regard des dessins annexés qui représentent - la figure 1 une vue en perspective d'un demi-train avant d'un kart, et - la figure 2 une vue de détail d'une rondelle de calage.The invention is described below according to a particular embodiment and a variant, this with reference to the appended drawings which represent - FIG. 1 a perspective view of a front undercarriage of a kart, and - FIG. 2 a detail view of a timing washer.
Sur la figure 1, on a représenté le châssis 10 sur lequel est rapporté un triangle inférieur 12, fixe et un triangle supérieur 14, articulé par rapport à ce châssis autour d'un axe 16, amovible.In Figure 1, there is shown the frame 10 on which is attached a lower triangle 12, fixed and an upper triangle 14, articulated relative to this frame about an axis 16, removable.
Entre les deux extrémités des triangles, il est monté un bras de direction 18. Des rotules 20, 22 sont interposées entre les extrémités du bras de direction et les extrémités des triangles.Between the two ends of the triangles, a steering arm 18 is mounted. Ball joints 20, 22 are interposed between the ends of the steering arm and the ends of the triangles.
Le bras de direction comprend également un arbre 24 support de roue.The steering arm also includes a wheel support shaft 24.
Une tringle 26 relie le bras de direction avec le système de contrôle de la direction, non représenté.A rod 26 connects the steering arm with the steering control system, not shown.
Le triangle inférieur étant fixe, c'est le triangle supérieur qui est réglable.The lower triangle being fixed, it is the upper triangle which is adjustable.
Ces moyens de réglage 28 comprennent une chape 30 dont les oreilles 32 sont solidaires du châssis.These adjustment means 28 comprise a yoke 30 whose ears 32 are secured to the chassis.
Un axe 34 traverse les oreilles et la base du triangle supérieur 14.An axis 34 crosses the ears and the base of the upper triangle 14.
La largeur de la base du triangle est inférieure à l'espace entre les oreilles et des cales 36 sont interposées de part et d'autre de la base du triangle, entre les oreilles.The width of the base of the triangle is less than the space between the ears and wedges 36 are interposed on either side of the base of the triangle, between the ears.
Il suffit de retirer l'axe, de faire passer cet axe à travers la seule première oreille, de placer les cales d'épaisseur souhaitée d'un côté de la base du triangle, de faire passer l'axe à travers ces cales puis à travers la base du triangle, de placer les cales complémentaires de l'autre côté de la base du triangle, puis de faire passer l'axe à travers ces cales et la seconde oreille de la chape.It is enough to remove the axis, to pass this axis through the first ear only, to place the shims of desired thickness on one side of the base of the triangle, to pass the axis through these shims then to through the base of the triangle, place the complementary shims on the other side of the base of the triangle, then pass the axis through these shims and the second ear of the yoke.
Le serrage de l'écrou 37 sur l'axe assure le blocage du montage.The tightening of the nut 37 on the axis ensures the blocking of the assembly.
Pour modifier le réglage il suffit de modifier le nombre ou l'épaisseur des cales disposées de part et d'autre de la base du triangle supérieur.To modify the setting, it suffices to modify the number or the thickness of the shims arranged on either side of the base of the upper triangle.
Sur la figure 2, on a représenté une variante de réalisation des cales.In Figure 2, there is shown an alternative embodiment of the shims.
Chaque cale telle que représentée, comprend un corps 40, cylindrique comprenant un logement 42, et un prolongement 44, tous deux orientés suivant l'axe longitudinal de l'axe 34.Each wedge as shown, comprises a cylindrical body 40 comprising a housing 42, and an extension 44, both oriented along the longitudinal axis of the axis 34.
Par ailleurs cette cale comprend une fente 46 de largeur supérieure au diamètre de l'axe.Furthermore, this wedge comprises a slot 46 of width greater than the diameter of the axis.
Ces cales évitent le démontage de l'axe. Il suffit de desserrer l'écrou 37 de l'axe 34 pour que les cales puissent être retirées ou mises en place.These shims prevent the disassembly of the axis. It is sufficient to loosen the nut 37 of the axis 34 so that the shims can be removed or put in place.
La fente permet le retrait ou la mise en place perpendiculairement à l'axe.The slot allows removal or installation perpendicular to the axis.
De plus, le prolongement axial de l'une des cales est prévu pour coopérer avec le logement correspondant de la cale qui est juxtaposée, de façon à réaliser une certaine continuité tel un manchon.In addition, the axial extension of one of the shims is provided to cooperate with the corresponding housing of the shim which is juxtaposed, so as to achieve a certain continuity such as a sleeve.
Il suffit de prévoir l'épaisseur des cales en fonction de la géométrie du châssis pour obtenir un réglage degré par degré.It suffices to provide the thickness of the shims as a function of the geometry of the chassis in order to obtain a degree by degree adjustment.
Le montage du triangle supérieur sur l'axe 34 est réalisé au moyen de bagues anti-friction sur lesquelles viennent porter les cales, ce qui évite la détérioration des cales et de la base du triangle lors des mouvements du triangle par rapport au châssis. The mounting of the upper triangle on the axis 34 is carried out by means of anti-friction rings on which the wedges come to bear, which avoids deterioration of the wedges and of the base of the triangle during movements of the triangle relative to the chassis.
De façon avantageuse, les valeurs de l'angle de chasse seront comprises entre 5 et 150 dans le cas du kart.Advantageously, the values of the hunting angle will be between 5 and 150 in the case of the kart.
en ce qui concerne le montage, c'est le triangle inférieur qui est fixe mais il est possible de prévoir un triangle supérieur fixe et un triangle inférieur mobile. as regards the assembly, it is the lower triangle which is fixed but it is possible to provide a fixed upper triangle and a movable lower triangle.
