Description
La présente invention se rapporte à un joint à rotu-The present invention relates to a rotary joint
le, notamment destiné à la timonerie de direction de véhicules automobiles, dont le corps et le bras de raccordement forment the, particularly intended for the steering wheel of motor vehicles, whose body and the connecting arm form
un seul bloc, ledit bras de raccordement étant taraudé. a single block, said connecting arm being threaded.
En présence d'un joint dont le corps et le bras de raccordement sont réalisés en un seul bloc à partir d'une pièce préformée venue de forgeage, et dans lequel le taraudage est ménagé dans un alésage borgne prévu de manière habituelle dans ledit bras de raccordement, étant donné que ledit alésage est borgne du côté dudit corps, un intervalle important entre le centre de la rotule et la limite de profondeur maximale de vissage est inévitable et dû à des impératifs techniques de réalisation lorsque ledit taraudage est ménagé dans l'alésage borgne. Dans ces conditions, il est impossible d'obtenir avantageusement une plage de réglage maximale entre le joint et la timonerie de direction. De plus, les joints connus présentent également In the presence of a seal whose body and the connecting arm are made in one piece from a preformed piece forging, and wherein the tapping is formed in a blind bore provided in the usual way in said arm connection, since said bore is blind on the side of said body, a large gap between the center of the ball and the limit of maximum depth of screwing is inevitable and due to technical requirements of realization when said tapping is formed in the bore blind. Under these conditions, it is impossible to advantageously obtain a maximum adjustment range between the seal and the steering linkage. In addition, the known seals also present
l'inconvénient que le taraudage ne peut pas être ménagé propre- the disadvantage that the tapping can not be spared
ment, de sorte que les résidus métalliques résultant de son so that the metal residues resulting from its

La présente invention a donc pour objet un joint à rotule du type précité, permettant une course de réglage aussi grande que possible sans pour autant allonger le bras The present invention therefore relates to a ball joint of the aforementioned type, allowing a control stroke as large as possible without lengthening the arm

Selon d'autres formes de réalisation avantageuses de l'invention, l'espace libre consiste en un orifice According to other advantageous embodiments of the invention, the free space consists of an orifice

ge. L'invention sera décrite plus en détail en regard des dessins annexés à titre d'exemples nullement limitatifs et sur lesquels: *la figure 1 est une vue en élévation illustrant le joint à rotule selon l'invention assujetti à la tige de commande; la figure 2 est une coupe partielle suivant la ligne II-II de la figure 3; la figure 3 est une vue par-dessus dudit joint à rotule; la figure 4 est une coupe suivant la ligne IV-IV de la figure 3; la figure 5 est une vue en élévation illustrant une variante de réalisation du joint selon l'invention; la figure 6 est une coupe suivant la ligne VI-VI la figure 7; la figure 7 est une vue par-dessus du joint de la figure 5; et la figure 8 est une coupe suivant la ligne VIIIVIII ge. The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting examples and in which: FIG. 1 is an elevational view illustrating the ball joint according to the invention, which is fastened to the control rod; Figure 2 is a partial section along the line II-II of Figure 3; Figure 3 is a view over said ball joint; Figure 4 is a section along the line IV-IV of Figure 3; Figure 5 is an elevational view illustrating an alternative embodiment of the seal according to the invention; Figure 6 is a section along the line VI-VI of Figure 7; Figure 7 is a view over the seal of Figure 5; and FIG. 8 is a section along line VIIIVIII
de la figure 7.of Figure 7.
Le joint illustré sur la figure 1 comprend de ma- The seal illustrated in Figure 1 comprises of
nière connue un corps 1 dans lequel est montée la rotule 2 d'une fusée. A son extrémité supérieure en observant la figure, known a body 1 in which is mounted the ball 2 of a rocket. At its upper end by observing the figure,
le corps 1 est fermé par un couvercle 3 et il est rendu étan- the body 1 is closed by a lid 3 and is made
che par un capuchon élastique 4 à son extrémité tournée vers ladite rotule. Ce corps 1 supporte un bras ou manchon 5 qui, che by an elastic cap 4 at its end facing said ball. This body 1 supports an arm or sleeve 5 which,
coudé à angle droit en direction dudit corps, permet le rac- bent at a right angle to said body, allows the connection
cordement à une timonerie de direction,par exemple à une barre d'accouplement 6, et qui, à cet effet, présente un taraudage 7 connection to a steering linkage, for example to a coupling rod 6, and which, for this purpose, has a tapping 7
dans lequel est vissé un filetage 8-de ladite barre d'accouple- in which is screwed a thread 8-of said coupling rod-

Selon la forme de réalisation de la figure 1, dans According to the embodiment of FIG.
la zone de transition 10 du manchon 5 au corps 1, entre l'ex- the transition zone 10 of the sleeve 5 to the body 1, between the former
trémité du taraudage ouvert en direction du corps et la paroi la de ce dernier, est ménagé un espace libre 11 qui s'étend essentiellement perpendiculairement à l'axe dudit alésage et traverse la zone de transition entre ledit corps 1 et ledit manchon 5, comme on le voit en particulier sur la figure 4. De la sorte, il est possible de réduire l'intervalle entre le centre de la rotule ou le corps du joint et la limite de profondeur maximale de vissage de la barre d'accouplement, afin de pouvoir augmenter la plage de réglage. En outre, cette forme de réalisation présente des avantages quant à l'usinage du taraudage car, dorénavant, les résidus métalliques provenant de cet usinage peuvent être évacués facilement par l'extrémité de l'alésage située du côté du corps. the opening of the tapping open towards the body and the wall of the latter, is formed a free space 11 which extends substantially perpendicular to the axis of said bore and passes through the transition zone between said body 1 and said sleeve 5, as this is seen in particular in FIG. 4. In this way, it is possible to reduce the gap between the center of the ball joint or the body of the seal and the limit of maximum depth of screwing of the tie rod, in order to ability to increase the setting range. In addition, this embodiment has advantages in machining the tapping because, from now on, the metal residues from this machining can be easily removed by the end of the boring located on the body side.
La forme de réalisation de la figure 5 ne se distin- The embodiment of Figure 5 is not distinguishable

De ce fait, dans la partie supérieure de ladite zone de transition, est réalisée une liaison 12 en forme de couvercle solidarisant in the form of a recess directed from below upwards. As a result, in the upper part of the transition zone, a connection 12 is formed in the form of a lid
