Description

DISPOSITIF DE LIAISON D'UN ENSEMBLE DE BIELLETTES AVEC
UNE CREMAILLERE DE DIRECTION.DEVICE FOR CONNECTING A CONNECTING ROD ASSEMBLY WITH
A STEERING RACK.

L'invention concerne un dispositif de liaison d'un ensemble de biellettes avec une crémaillère de direction respectivement montées pivotantes autour d'un axe et dans lequel des manchons élastiques sont disposés entre la tête de l'une de ces biellettes et l'axe.The invention relates to a device for connecting a set of rods with a steering rack respectively pivotally mounted about an axis and in which elastic sleeves are arranged between the head of one of these rods and the axis.

On sait que la position du poste de conduite dans le véhicule détermine la position de l'arbre de direction qui relie le volant au pignon d'attaque de la crémaillère. Lorsque la crémaillère est reliée aux leviers des porte-fusées droit et gauche du train directeur du véhicule, il est connu d'articuler les têtes de chaque biellette autour d'un axe porté par un bras rigidement fixé à la crémaillère.It is known that the position of the driving position in the vehicle determines the position of the steering shaft which connects the steering wheel to the driving pinion of the rack. When the rack is connected to the levers of the right and left stub axle carriers of the steering train of the vehicle, it is known to articulate the heads of each link around an axis carried by an arm rigidly fixed to the rack.

L'un des buts de l'invention est de réaliser une articulation de biellettes possédant un nombre de pièces plus réduit et dont le montage est simplifié.One of the objects of the invention is to produce a link articulation having a smaller number of parts and the mounting of which is simplified.

A cet effet, le dispositif de solidarisation d'un ensemble de deux biellettes à un bras actionné par la crémaillère, du type comportant des manchons élastiques disposés entre ledit bras et la tête d'une biellette, est caractérisé par le fait que les manchons sont de façon en soi connue coaxiaux et concentriques et sont séparés par une douille intermédiaire dont une extrémité est conformée en un flasque radial de fixation solidarisé avec le bras actionné par la crémaillère.To this end, the device for securing a set of two rods to an arm actuated by the rack, of the type comprising elastic sleeves disposed between said arm and the head of a rod, is characterized in that the sleeves are in a manner known per se coaxial and concentric and are separated by an intermediate bushing, one end of which is shaped as a radial fixing flange secured to the arm actuated by the rack.

Le dispositif ainsi réalisé facilite le préassemblage de l'ensemble des biellettes avant leur solidarisation avec la crémaillère. The device thus produced facilitates the pre-assembly of all the rods before they are joined to the rack.

La disposition relative des biellettes avec interposition d'un ensemble de manchons élastiques assure également l'amortissement des mouvements d'oscillation longitudinaux ou de rotation tout en permettant un mouvement de rotation relatif entre les biellettes.The relative arrangement of the rods with the interposition of a set of elastic sleeves also ensures the damping of the longitudinal oscillation or rotational movements while allowing relative rotational movement between the rods.

D'autres caractéristiques de l'invention ressortiront de la description qui suit faite en référence au dessin annexé dans lequel - la figure 1 est une vue en coupe axiale du dispo
sitif - la figure 2 est une vue en coupe axiale d'une
variante de réalisation du dispositif.Other characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing in which - FIG. 1 is a view in axial section of the device.
sitif - Figure 2 is an axial sectional view of a
variant of the device.

La figure 1 représente un ensemble de deux biellettes 1, 2 rendues solidaires d'une crémaillère de direction 3 au moyen d'un bras 4. Le bras -4 rigidement relié à la crémaillère 3 est réalisé sous la forme d'un étrier en tôle pliée dont les branches latérales 5 sont accolées à deux flancs parallèles de la crémaillère 3. Le plancher 6 du bras 4 comporte l'ouverture de passage 7 d'une douille intermédiaire 8 dont l'extrémité est conformée en un flasque radial 9 solidarisé au moyen de rivets 10 avec le bras 4. Sur la surface cylindrique de l'alésage de la douille est vulcanisé un manchon élastique 11 comprimé radialement et allongé axialement entre une douille centrale 12 et la douille intermédiaire 8. La douille intérieure 12 est traversée par un axe d'articulation 13.FIG. 1 represents a set of two rods 1, 2 made integral with a steering rack 3 by means of an arm 4. The arm -4 rigidly connected to the rack 3 is produced in the form of a sheet metal stirrup folded, the lateral branches 5 of which are attached to two parallel sides of the rack 3. The floor 6 of the arm 4 has the passage opening 7 of an intermediate sleeve 8, the end of which is shaped as a radial flange 9 secured to the means of rivets 10 with the arm 4. On the cylindrical surface of the bore of the sleeve is vulcanized an elastic sleeve 11 compressed radially and elongated axially between a central sleeve 12 and the intermediate sleeve 8. The inner sleeve 12 is crossed by an axis hinge 13.

Selon le mode de réalisation représenté à la figure 1, l'axe 13 est constitué par un boulon engagé dans une fourche de retenue 14 qui constitue la tête 15 d'une biellette 1 . La tête 17 de l'autre biellette 2 porte intérieurement un deuxième manchon élastique 18 solidarisé extérieurement et intérieurement avec deux douilles 19, 20 entre lesquelles il est aussi comprimé radialement et allongé axialement. L'ensemble du manchon 18 et des douilles 19, 20 est disposé coaxialement et concentriquement sur la douille intermédiaire 8.According to the embodiment shown in FIG. 1, the axis 13 is constituted by a bolt engaged in a retaining fork 14 which constitutes the head 15 of a link 1. The head 17 of the other link 2 internally carries a second elastic sleeve 18 secured externally and internally with two sockets 19, 20 between which it is also compressed radially and elongated axially. The assembly of the sleeve 18 and of the sockets 19, 20 is arranged coaxially and concentrically on the intermediate socket 8.

Sur la figure 2 qui représente une variante de réalisation du dispositif de liaison, l'axe d'articulation 213 de la tête 214 de biellette 215 est rigidement relié à l'autre biellette 216. Les autres organes du dispositif possèdent la même fonction et sont agencés identiquement aux organes décrits en référence à la figure 1.In FIG. 2 which represents an alternative embodiment of the connection device, the articulation axis 213 of the head 214 of link rod 215 is rigidly connected to the other link 216. The other members of the device have the same function and are arranged identically to the organs described with reference to FIG. 1.

Les manchons élastiques et les différentes douilles portent de ce fait les repères présentement utilisés lors de la description de la figure 1. The elastic sleeves and the different sockets therefore bear the marks presently used in the description of FIG. 1.
