Abstract

The coupling element has a radial shape with holes at the ends of the arms, sleeved and lined with elastic compound. The arms bolt to similar arms in the other shaft section, and to its own shaft via a central sleeved hole (12). The radial arms and sleeves provide an elastic coupling element with a failsafe drive if the elastic layers are damaged. In this case the drive is via the metal sleeves.

La présente invention concerne un joint de couplage entre une colonne de direction et l'essieu à crémaillère des roues, dont application sur les véhicules est d'une réali station et d1un fonctionnement particulièrement faciles On connaît bien l'importance de cet élément pour la trans- mission du mouvement de direction;; mais habituellement, il est réalisé en matériau élastomère, , ce qui nécessite d'y noyer un grillage de fil synthétique ou meme méLallique, afin d'améliorer sa résistance aux sollicitations mécaniques
Cette solution laborieuse présente en outre divers inconv6- nients, dont la plus grave est l'inaptitude fonctionnelle en cas de rupture, avec les graves conséquences que cela comporte pour la stabilité du véhicule.The present invention relates to a coupling joint between a steering column and the rack-and-pinion axle of the wheels, the application of which on vehicles is particularly practical and easy to operate. The importance of this element is well known for the trans - mission of the management movement; but usually it is made of elastomeric material, which necessitates drowning a mesh of synthetic or even metallic wire therein, in order to improve its resistance to mechanical stresses.
This laborious solution also has various drawbacks, the most serious of which is functional incapacity in the event of a breakdown, with the serious consequences that this has for the stability of the vehicle.

La réalisation en est de plus remarquablement anti-économique, en raison notamment du type de matériau élastique employé, qui nécessite des traitements et la mise en place compliquée de l'insert de renforcement
Le but de l'invention est de remédier à cet inconvénient en faisant appel à un dispositif qui assure une plus grande sécurité de fonctionnement même en cas de détérioration, de construction simple, facile et rapide, d'un usage prolongé dans le temps,et présentant ainsi un avantage économique.The production is moreover remarkably uneconomic, in particular because of the type of elastic material used, which requires treatments and the complicated installation of the reinforcement insert.
The object of the invention is to remedy this drawback by using a device which provides greater operational safety even in the event of deterioration, of simple, easy and rapid construction, of prolonged use over time, and thus presenting an economic advantage.

Ces avantages, et d'autres qui apparaîtront dans la description détaillée qui suit, sont obtenus grâce à un joint caractérisé en ce qu'il est réalisé en matériau plastique estampé et durci,~et muni en outre de bossages appropriés ménagés directement sur des lobes disposés en croisillon et équidis- tants entre eux, lesdits bossages étant aptes à loger des moyens destinés à recevoir des organes de liaison.These advantages, and others which will appear in the detailed description which follows, are obtained thanks to a seal characterized in that it is made of stamped and hardened plastic material, ~ and further provided with suitable bosses formed directly on lobes. arranged in a cross and equidistant from each other, said bosses being capable of accommodating means intended to receive connecting members.

D'autres caractéristiques de l'invention ressortiront de la description donnée ci-après, à titre illustratif et non limitatif, dtun mode de réalisation préféré, et des dessins annexés, dans lesquels la figure i représente- schématiquement, à échelle réduite, un système de direction incorporant un joint selon l'invention; la figure 2 est une vue frontale du joint; la figure 3 est une rue en coupe selon la ligne- 111-111 de la figure 2.Other characteristics of the invention will emerge from the description given below, by way of nonlimiting illustration, of a preferred embodiment, and of the appended drawings, in which FIG. 1 schematically represents, on a reduced scale, a system steering incorporating a seal according to the invention; Figure 2 is a front view of the seal; Figure 3 is a sectional street along the line 111-111 of Figure 2.

En se référant aux figures,1 et 2 désignent des barres liées entre elles par un joint à cardan 3 et formant la colonne de direction connue d'un véhicule automobile.Referring to the figures, 1 and 2 denote bars linked together by a universal joint 3 and forming the known steering column of a motor vehicle.

Traditionnellement, le mouvement de direction est transmis de la colonne à l'essieu des roues antérieures par l'inter- médiaire d'une crémaillère transversale engrenant avec un pignon couplé à son tour à la denture interne 4 d'un manchon 4a positionné en alignement axial avec la colonne de direction.Traditionally, the steering movement is transmitted from the column to the axle of the front wheels via a transverse rack meshing with a pinion in turn coupled to the internal toothing 4 of a sleeve 4a positioned in alignment axial with the steering column.

Entre le manchon 4a et la bride d'extrémité 5 incorporée à la barre 1 de la colonne de direction, est relié, au moyen d'organes de blocage traditionnels tels que des boulons 6, un joint désigné dans son ensemble par 7 et destiné spéciale- ment à la transmission du mouvement entre ces parties (voir en particulier la figure 1). Between the sleeve 4a and the end flange 5 incorporated in the bar 1 of the steering column, is connected, by means of traditional locking members such as bolts 6, a seal designated as a whole by 7 and intended for special - ment to the transmission of movement between these parts (see in particular Figure 1).

Selon la caractéristique essentielle de l'invention, le joint 7 est réalisé en matériau plastique estampé et durci, et présente une configuration structurale en croisillon, avec quatre lobes (8) ayant entre eux des distances angulaires égales.According to the essential characteristic of the invention, the seal 7 is made of stamped and hardened plastic material, and has a structural configuration in cross, with four lobes (8) having between them equal angular distances.

A l'extrémité extérieure de chaque lobe 8 est ménagé un bossage 9 muni d'un siège cylindrique apte à logex directement, avec intervention d'une liaison inamovible, un petit tube métallique 10, lequel reçoit la tige du boulon 6, réa- lisant le blocage sur la colonne de direction. Les petits tubes 10 ont tous les mêmes dimensions, ainsi que les bossages 9.At the outer end of each lobe 8 is provided a boss 9 provided with a cylindrical seat suitable for logex directly, with the intervention of an irremovable link, a small metal tube 10, which receives the rod bolt 6, making blocking on the steering column. The small tubes 10 all have the same dimensions, as do the bosses 9.

Sur une platine centrale 11 d'épaisseur accrue par rapport aux lobes 8 est rrnénagée une protubérance cylindrique 12 des tinée au montage du joint 7 sur un appendice 13 d l'extrémité axialement interne du manchon 4a. Le bossage 12 a des dimensions légèrement plus grandes que les bossages périphériques 9.On a central plate 11 of increased thickness compared to the lobes 8, a cylindrical protuberance 12 is arranged for mounting the seal 7 on an appendage 13 of the axially internal end of the sleeve 4a. The boss 12 has slightly larger dimensions than the peripheral bosses 9.

Tous les bossages 9 et 12 présentent des trous axiaux traver- sants et font saillie symétriquement dans une mesure égale par rapport à la platine de retenue il (voir les figures 2 et 3).All the bosses 9 and 12 have transverse axial holes and project symmetrically in an equal measure with respect to the retaining plate il (see FIGS. 2 and 3).

Le joint ainsi réalisé est avantageusement revêtu d'ùne enveloppe traditionnelle en matériau synthétique.The joint thus produced is advantageously coated with a traditional envelope of synthetic material.

Il ressort de la description et des dessins, outre la sécurité de conduite, qui permet, même dans le cas toujours à craindre d'une rupture du joint, grâce à sa réalisation en matériau plastique, un fonctionnement apportant -une garantie appréciable contre les accidents aux usagers du véhicule, également la facilité et la simplicité de construction, obtenues par une structure monolithique et une certaine uniformité dimensionnelle et par des inserts métalliques tubulaires modulaires, constitués par des petits tubes montés facilement et rapidement dans les sièges des bossages.It emerges from the description and the drawings, in addition to driving safety, which allows, even in the case always to be feared of a rupture of the joint, thanks to its realization in plastic material, an operation bringing -an appreciable guarantee against accidents. to vehicle users, also the ease and simplicity of construction, obtained by a monolithic structure and a certain dimensional uniformity and by modular tubular metal inserts, constituted by small tubes mounted easily and quickly in the seats of the bosses.

A titre d'avantage supplémentaire, l'application du joint objet de l'invention peut s'étendre à divers autres.;secteurs, tels par;exemple que la transmission du mouvement tant aux essieux de véhicules qu'aux arbres d'outillages fixes de divers types.As an additional advantage, the application of the seal that is the subject of the invention can extend to various other sectors; such as, for example, the transmission of movement both to vehicle axles and to fixed tool shafts of various types.

L'invention n'est pas limitée à la réalisation décrite, mais s'étend aux équivalents et aux variantes tendant à apporter des améliorations techniques et économiques, sans pour cela s'écarter de l'esprit de l'invention. The invention is not limited to the embodiment described, but extends to equivalents and variants tending to bring technical and economic improvements, without thereby departing from the spirit of the invention.
