Abstract
Description
La présente invention concerne une barre anti-devers pour véhicules automobiles et plus particulièrement les moyens de raccord des extrémités de ladite barre avec l'embout d'une biellette reliée par ailleurs à la suspension ou aux amortisseurs. The present invention relates to an anti-roll bar for motor vehicles and more particularly to the means for connecting the ends of said bar with the end piece of a rod connected moreover to the suspension or to the shock absorbers.
Généralement, la barre a un profil cintré en U avec deux bras latéraux. Les extrémités de chaque bras sont forgées, percées et taraudées pour former un logement destiné à recevoir directement par vissage, lors du montage, un embout mâle fileté solidaire de la biellette. Generally, the bar has a curved U-shaped profile with two lateral arms. The ends of each arm are forged, drilled and tapped to form a housing intended to receive directly by screwing, during assembly, a threaded male end secured to the link.
Cependant, comme la barre doit être traitée thermiquement et cintrée à chaud, il est impossible de forger ses extrémités après le cintrage car cette nouvelle élévation de température modifierait ses propriétés mécaniques. However, as the bar must be heat treated and bent hot, it is impossible to forge its ends after bending because this new rise in temperature would modify its mechanical properties.
En outre, le logement taraudé des extrémités forgées ne peut supporter ni le traitement thermique ni le cintrage qui risqueraient d'entraîner des déformations irréversibles. In addition, the threaded housing of the forged ends cannot withstand the heat treatment or the bending which would risk causing irreversible deformations.
Dans ces conditions, le traitement thermique et le cintrage ne peuvent être effectués qu'après le forgeage des extrémités de la barre, et avant de réaliser les logements taraudés dans lesdites extrémités forgées. Under these conditions, the heat treatment and the bending can only be carried out after the forging of the ends of the bar, and before making the threaded housings in said forged ends.
Mais la reprise des extrémités forgées pour usinage est une opération très onéreuse. However, the recovery of the forged ends for machining is a very expensive operation.
Au surplus, un recuit desdites extrémités reste dans tous les cas nécessaire, or cette opération modifie les résultats du traitement thermique qui ne sont plus homogènes, ce qui peut entraîner des problèmes de résistance mécanique en service. In addition, annealing of said ends remains necessary in all cases, or this operation modifies the results of the heat treatment which are no longer homogeneous, which can lead to problems of mechanical strength in service.
La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante. The present invention aims to solve these technical problems satisfactorily.
Ce but est atteint selon l'invention, au moyen d'une barre anti-devers pour véhicule dont les extrémités sont pourvues de moyens de raccord amovible avec l'embout d'une biellette reliée, par ailleurs, à la suspension ou aux amortisseurs,
caractérisée en ce que lesdits moyens de raccord comprennent un logement réalisé aux extrémités de ladite barre et dans lequel est fixé un insert taraudé, destiné à coopérer par vissage avec l'embout fileté de ladite biellette. This object is achieved according to the invention, by means of an anti-roll bar for a vehicle, the ends of which are provided with removable connection means with the end piece of a link rod connected, moreover, to the suspension or to the shock absorbers,
characterized in that said connection means comprise a housing produced at the ends of said bar and in which is fixed a threaded insert, intended to cooperate by screwing with the threaded end of said link.
Selon un premier mode de réalisation ledit logement s'étend traversalement à l'extrémité de ladite barre. According to a first embodiment, said housing extends transversely at the end of said bar.
Selon un autre mode de réalisation, ledit logement s'étend dans le prolongement de l'extrémité de ladite barre. According to another embodiment, said housing extends in the extension of the end of said bar.
Ce dernier mode de réalisation est plus particulièrement adapté à des barres tubulaires. This latter embodiment is more particularly suitable for tubular bars.
Selon une variante, ledit logement est cylindrique. According to a variant, said housing is cylindrical.
Selon une autre variante, ledit logement a une section polygonale. According to another variant, said housing has a polygonal section.
Selon une autre caractéristique, ledit insert est fixé dans ledit logement par rivetage ou sertissage. According to another characteristic, said insert is fixed in said housing by riveting or crimping.
La présente invention permet de rapporter le filetage dans un logement ménagé aux extrémités forgées de la barre. The present invention makes it possible to attach the thread to a housing formed at the forged ends of the bar.
Cette disposition autorise l'usinage des extrémités en cours de forgeage, par exemple, par poinçonnage pour former lesdits logements. This arrangement allows the machining of the ends during forging, for example, by punching to form said housings.
On effectue ensuite le cintrage et le traitement thermique de la barre usinée (trempe et revenu) puis on fixe les inserts dans les logements d'extrémités sans qu'il soit nécessaire de procéder à un recuit. The bending and the heat treatment of the machined bar are then carried out (quenching and tempering), then the inserts are fixed in the end housings without the need for annealing.
Un autre avantage de l'invention réside dans la possibilité de modifier ou de réparer rapidement le raccordement de l'embout de biellette avec les extrémités de la barre en désolidarisant et en remplaçant l'insert. Another advantage of the invention lies in the possibility of quickly modifying or repairing the connection of the connecting rod end with the ends of the bar by separating and replacing the insert.
Les opérations de maintenance sont ainsi facilitées. Maintenance operations are thus facilitated.
L'invention sera mieux comprise à la lecture de la description qui va suivre, accompagnée des dessins sur lesquels
- la figure 1 représente une vue schématique d'ensemble et en perspective d'une barre anti-devers traditionnelle avec les moyens de raccord aux biellettes;
- les figures 2a et 2b représentent des vues en coupe partielle d'un mode de réalisation de l'invention;
- la figure 3 représente une vue en perspective d'une variante de réalisation
- la figure 4 représente une vue en coupe partielle d 'un autre mode de réalisation de l'invention.The invention will be better understood on reading the description which follows, accompanied by the drawings on which
- Figure 1 shows a schematic overview and perspective of a traditional anti-roll bar with the connecting means to the rods;
- Figures 2a and 2b show views in partial section of an embodiment of the invention;
- Figure 3 shows a perspective view of an alternative embodiment
- Figure 4 shows a partial sectional view of another embodiment of the invention.
La barre anti-devers 1 représentée sur la figure 1 a un profil en
U avec deux bras latéraux la et lb et un tronçon central 1c fixé sur le châssis (non représenté) au moyen de paliers P. Elle comporte des moyens traditionnels de raccord avec des biellettes 2 articulées, reliées par ailleurs, à la suspension ou aux amortisseurs (non représentés).The anti-roll bar 1 represented in FIG. 1 has a profile in
U with two lateral arms 1a and 1b and a central section 1c fixed to the chassis (not shown) by means of bearings P. It comprises traditional means of connection with articulated links 2, connected moreover, to the suspension or to the shock absorbers (not shown).
Les biellettes 2 sont pourvues d'un embout 20 fileté destiné à venir se verrouiller par vissage dans un logement taraudé 10 ménagé dans les extrémités forgées respectives ld, le des bras la, lb de la barre 1. The rods 2 are provided with a threaded end piece 20 intended to be locked by screwing in a threaded housing 10 formed in the respective forged ends 1d, the of the arms 1a, 1b of the bar 1.
Sur la figure 1, la biellette est déjà montée sur le bras droit lb tandis qu'elle ne l'est pas encore sur le bras gauche la. In FIG. 1, the link is already mounted on the right arm 1b while it is not yet mounted on the left arm 1a.
Les figures 2a et 2b représentent des vues partielles en coupe de l'extrémité forgée ld du bras la de la barre 1 de l'invention, l'extrémité ld est pourvue de moyens de raccord amovible avec l'embout 20 de la biellette 2. Ces moyens de raccord comprennent un logement 10 réalisé par usinage de l'extrémité forgée ld, dans lequel on vient fixer un insert 3 cylindrique pourvu de filets internes 31, réalisés par taraudage et destiné à coopérer par vissage avec l'embout fileté 20. Dans le mode de réalisation représenté sur la figure 2a, le logement 10 s'étend traversalement et de part en part de l'extrémité forgée ld de la barre 1. FIGS. 2a and 2b show partial sectional views of the forged end ld of the arm 1a of the bar 1 of the invention, the end 1d is provided with removable connection means with the end piece 20 of the link 2. These connection means comprise a housing 10 produced by machining the forged end ld, in which a cylindrical insert 3 is provided with internal threads 31, produced by tapping and intended to cooperate by screwing with the threaded end piece 20. In the embodiment shown in FIG. 2a, the housing 10 extends transversely and right through from the forged end 1d of the bar 1.
Sur la figure 2b, l'insert 3 est retenu dans le logement 10 par rivetage ou sertissage en écrasant ses bords longitudinaux 3a, 3b qui font saillie à l'extérieur contre les flancs latéraux externes de l'extrémité ld, autour du logement 10. In FIG. 2b, the insert 3 is retained in the housing 10 by riveting or crimping by crushing its longitudinal edges 3a, 3b which protrude outside against the external lateral flanks of the end ld, around the housing 10.
Dans ce cas, il est nécessaire que la longueur de l'insert 3 soit supérieure à celle du logement transversal 10. In this case, the length of the insert 3 must be greater than that of the transverse housing 10.
On peut également concevoir une variante de réalisation dans laquelle le logement 10 est aveugle. L'insert 3 est alors introduit dans le logement par le côté ouvert puis est éventuellement mis en butée contre le fond dudit logement où il est retenu par déformation, collage, soudure ou tout autre mode de fixation approprié. One can also conceive an alternative embodiment in which the housing 10 is blind. The insert 3 is then introduced into the housing by the open side and is then possibly abutted against the bottom of said housing where it is retained by deformation, gluing, welding or any other suitable method of fixing.
La figure 3 représente une autre variante dans laquelle la barre 1 est tubulaire et dépourvue d'extrémité forgée. FIG. 3 represents another variant in which the bar 1 is tubular and devoid of forged end.
Dans ce cas, le logement 10 s'étend dans le prolongement de l'extrémité tubulaire ld et ici de façon coaxiale. In this case, the housing 10 extends in the extension of the tubular end 1d and here coaxially.
L'insert 3 est représenté avec un fond 30 mais on peut tout aussi bien prévoir de le faire déboucher à ses deux bords longitudinaux. The insert 3 is shown with a bottom 30 but it is equally possible to plan to have it open at its two longitudinal edges.
L'insert 3 est retenu dans le logement 10 par sertissage ou rivetage de son bord externe 3a sur le pourtour de l'orifice du logement 10. The insert 3 is retained in the housing 10 by crimping or riveting its external edge 3a around the periphery of the orifice of the housing 10.
La figure 4 représente un autre mode de réalisation dans lequel l'insert 3 possède une section polygonale qui est ici sensiblement carrée. FIG. 4 represents another embodiment in which the insert 3 has a polygonal section which is here substantially square.
Le logement 10 est transversal et a une section complémentaire permettant l'introduction de l'insert 3, en force avec déformations éventuelles ou par libre coulissement.The housing 10 is transverse and has a complementary section allowing the insertion of the insert 3, in force with possible deformations or by free sliding.
Les filets internes 31 réalisés par taraudage sont, de préférence, coaxiaux à l'axe longitudinal de l'insert. The internal threads 31 produced by tapping are preferably coaxial with the longitudinal axis of the insert.
