La presente invention concerne, de facon generale, les systemes de direction pour vehicules automobiles. Wile se rapporte, plus particulierement, aux directions a cremaillere, avec un pigeon de direction venant en prise avec la cremaillere, I'ensemble etant loge dans un carter de direction. Encore plus specialement, I'invention s'interesse a un dispositif qui, pour ce genre de d i rection, assure un equilibrage entre les press ion s d' ai r a l' interieur de la direction et l'exterieur de celle-ci. Cette invention est applicable aux directions The present invention relates, in general, to steering systems for motor vehicles. Wile relates, more particularly, to rack-and-pinion steering, with a steering pigeon engaging the rack, the assembly being housed in a steering housing. Even more specifically, the invention is concerned with a device which, for this kind of direction, ensures a balance between the pressure s to have inside the direction and the outside of it. This invention is applicable to directions
manuelles, ainsi qutaux directions a assistance hydraulique ou electrique. manual, as well as hydraulic or electric power steering.
Une direction a cremaillere de vehicule automobile est habituellement realisee de facon totalement etanche, afin d'eviter toute entree A rack and pinion steering of a motor vehicle is usually carried out in a completely sealed manner, in order to avoid any entry
indesirable d'eau ou d'humidite a l'interieur de la direction. undesirable water or humidity inside the direction.
Ceci pose toutefois des problemes de surpression ou de depression dans la direction, en fonction de ['augmentation ou de la baisse de temperature environnante. En particulier, en cas de changements brutaux de la temperature, la surpression ou depression entrane une deformation exageree des soufflets de la direction, situes autour des extremites de la cremaillere, However, this poses problems of overpressure or depression in the direction, depending on the increase or decrease in the surrounding temperature. In particular, in the event of sudden changes in temperature, the overpressure or depression causes an exaggerated deformation of the steering bellows, located around the ends of the rack,
avec pour consequence une deterioration ou une destruction de ces soufflets. with consequent deterioration or destruction of these bellows.
Pour eviter cette deformation des soufflets, il a ete deja envisage de realiser des directions avec soufflets "respirants", qui permettent une circulation d'air entre l'interieur de la direction et l'exterieur, done une sortie ou une entree d'air, selon le cas (surpression ou depression). Cette solution connue necessite toutefois une fabrication speciale, done complexe et couteuse, des soufflets. De plus, elle ne permet pas la "respiration" de la direction lors d'une immersion (par exemple au passage d'un gue), et une To avoid this deformation of the bellows, it has already been envisaged to produce directions with "breathable" bellows, which allow air circulation between the inside of the direction and the outside, therefore an air outlet or inlet , depending on the case (overpressure or depression). This known solution, however, requires a special, therefore complex and expensive, manufacture of bellows. In addition, it does not allow the "breathing" of the steering during an immersion (for example when passing a gue), and a
depression qui se forme alors peut deformer et deteriorer les soufflets. depression which forms then can deform and deteriorate the bellows.
La presente invention a pour but de fournir une direction a cremaillere avec dispositif d'equilibrage des pressions entre l'interieur et l'exterieur de la direction, en vue d'eviter la deformation et la deterioration des soufflets, ce dispositif etant obtenu par une adaptation particulierement simple The present invention aims to provide a rack and pinion steering with pressure balancing device between the inside and the outside of the steering, in order to avoid the deformation and deterioration of the bellows, this device being obtained by a particularly simple adaptation
et economique de la structure de la direction. and economic management structure.
A cet effet, I'invention a pour objet une direction a cremaillere de vehicule automobile, comprenant un pigeon de direction en prise avec la cremaillere, I'ensemble etant loge dans un carter de direction, cette direction etant essentiellement caracterisee en ce que le carter de directiion, ou une partie de carter, est conforme et/ou prolonge de maniere a atteindre l'habitacle du vehicule concerne, ou du moins la paroi de cet habitacle, et en ce qutau moins une communication autorisant le passage de l'air est realisee en un point du carter de direction ou de ladite partie de carter atteignant l'habitacle, de tel le sorte qutune communication autorisant une circulation de l'air est To this end, the invention relates to a rack and pinion steering of a motor vehicle, comprising a steering pigeon in engagement with the rack and pinion, the assembly being housed in a steering housing, this steering being essentially characterized in that the housing direction, or part of the casing, conforms and / or extends so as to reach the passenger compartment of the vehicle concerned, or at least the wall of this passenger compartment, and in that at least one communication allowing the passage of air is carried out at a point on the steering gear or of said gear part reaching the passenger compartment, so that a communication allowing air circulation is
real isee entre l' interieur de la direction et l' habitacle du vehicul e. made between the interior of the steering and the passenger compartment of the vehicle.
Ainsi, I'idee inventive consiste ici a realiser une direction a cremaillere qui ntest pas entierement etanche, mais dont l'interieur communique seulement avec l'habitacle du vehicule, c'est-a-dire le compartiment reserve aux passagers, lequel n'est pas soumis aux intemperies et aux projections de liquides divers, ni au risque d'immersion lors d'un passage a gue. Pour atteindre l'habitacle, il suffit d'ajuster une partie de carter pour qu'elle jouxte cet habitacle, et de modifier legerement ladite partie de carter, notamment en realisant un simple alesage qui la traverse sur toute son epaisseur, et qui permet ainsi une circulation d'air entre l'habitacle et l'interieur de la direction. La solution proposee par la presente invention pour rendre la direction "respirante" s'avere, de la sorte, particulierement simple et economlque. Selon une forme de realisation de ['invention, la partie de carter atteignant l'habitacle est la partie de carter traversee par l'arbre d'entree de la direction, c'est-a-die l'arbre couple exterieurement a la colonne de direction, et interieurement au pigeon de direction. Dans ce cas, la communication autorisant le passage de l'air est realisee sous la forme d'un alesage ou d'un autre conduit analogue, menage dans ladite partie de carter sur le cote de l'arbre d'entree. Cette forme de realisation est plus particulierement applicable a une direction manuelle, ou a une direction avec assistance agissant sur la Thus, the inventive idea here consists in realizing a rack and pinion steering which is not entirely sealed, but whose interior communicates only with the passenger compartment of the vehicle, that is to say the compartment reserved for passengers, which does not is not subject to bad weather and splashes of liquids, nor to the risk of immersion during a passage to gue. To reach the passenger compartment, it suffices to adjust a part of the casing so that it adjoins this passenger compartment, and to slightly modify said part of the casing, in particular by making a simple bore which passes through it over its entire thickness, and which thus allows air circulation between the passenger compartment and the interior of the steering. The solution proposed by the present invention to make the steering "breathable" proves, in this way, particularly simple and economical. According to one embodiment of the invention, the part of the casing reaching the passenger compartment is the part of the casing crossed by the input shaft of the steering, that is to say the shaft couple externally to the column direction, and internally to the direction pigeon. In this case, the communication authorizing the passage of air is carried out in the form of a bore or other similar conduit, formed in said casing part on the side of the input shaft. This embodiment is more particularly applicable to manual steering, or to assisted steering acting on the
colonne de direction.steering column.
Selon une autre possibilite, la partie de carter atteignant l'habitacle est une partie de carter auxiliaire, telle que la carter d'un capteur de couple, ou le carter d'un reducteur, ceci notamment pour une direction a assistance electrique. 3 0 S' il est souhaite que la direction resiste aux eventuelies projections d'eau survenant dans l'habitacle, I'alesage ou autre conduit analogue, menage dans la partie de carter atteignant lthabitacle, peut recevoir un element d'obturation, tel qutune pastille ou un tampon, en une matiere poreuse According to another possibility, the part of the casing reaching the passenger compartment is a part of the auxiliary casing, such as the casing of a torque sensor, or the casing of a reduction gear, this in particular for an electrically assisted steering. 3 0 If it is desired that the management resists possible splashing water occurring in the passenger compartment, the bore or the like duct, arranged in the casing part reaching the passenger compartment, can receive a sealing element, such as lozenge or tampon, of porous material
permeable a l'air mais hydrophobe.air permeable but hydrophobic.
11 peut aussi etre souhaite que la direction stoppose a 1'entree de poussieres en provenance de l'habitacle. Dans ce cas, I' al esage ou autre conduit analogue, menage dans la partie de carter atteignant lthabitacle, peut recevoir un element d'obtu ration tel qu' une pasti l le ou u n tampon, en une matiere poreuse permeable a l'air et eventuellement a l'eau, mais faisant It may also be desirable for the management to stop the entry of dust from the passenger compartment. In this case, the bore or other similar duct, formed in the part of the casing reaching the passenger compartment, can receive a sealing element such as a pad or a pad, made of a porous material permeable to air. and possibly in the water, but doing
barrage aux poussieres.dust barrier.
Enfin, on notera que la partie de carter atteignant l'habitacle peut Finally, it should be noted that the part of the casing reaching the passenger compartment can
etre appliquee contre la paroi de cet habitacle avec interposition d'un joint. be applied against the wall of this cabin with the interposition of a seal.
L'invention sera de toute facon mieux comprise a ['aide de la The invention will in any case be better understood using the
description qui suit, en reference au dessin schematique annexe representant, description which follows, with reference to the diagrammatic annex drawing representing,
a titre d'exemple, une forme d'execution de cette direction a cremaillere de as an example, a form of execution of this rack and pinion direction

Figure 1 est une vue generale, exterieure, d'une direction a cremaillere conforme a ['invention; Figure 2 est une vue partielle a plus grande echelle de cette direction, suivant la fleche F de figure 1; Figure 3 est une vue en coupe suivant la ligne - de figure 2. La figure 1 represente exterieurement une direction a cremaillere, et plus particulierement une direction assistee electrique, equipant un vehicule automobile. Cette figure indique le compartiment moteur 2 du vehicule, et son habitacle ou compartiment passagers 3, compartiments qui vent separes l'un Figure 1 is a general view, outside, of a rack-and-pinion steering according to the invention; Figure 2 is a partial view on a larger scale of this direction, along the arrow F of Figure 1; Figure 3 is a sectional view along the line - of Figure 2. Figure 1 externally represents a rack-and-pinion steering, and more particularly an electric power steering, equipping a motor vehicle. This figure shows the engine compartment 2 of the vehicle, and its passenger compartment or compartment 3, compartments which separate one
de l'autre par une paroi 4.on the other by a wall 4.
La direction elle-meme comporte un carter central tubulaire 5, dans lequel est montee coulissante la cremaillere 6 (voir aussi figure 3). Les extremites droite et gauche de la cremaillere 6, exterieures au carter 5, vent accouplees a des biellettes 7. Deux soufflets 8, raccordes respectivement aux deux extremites du carter 5, recouvrent et protegent les zones d'extremite de la The steering itself comprises a tubular central casing 5, in which the rack 6 is slidably mounted (see also Figure 3). The right and left ends of the rack 6, outside the casing 5, are coupled to the rods 7. Two bellows 8, connected respectively to the two ends of the casing 5, cover and protect the end zones of the
cremaillere 6.rack 6.
La cremaillere 6 est en prise avec un pigeon de direction 9 (voir figure 3), lie en rotation a un arbre d'entree du mouvement 10. L'arbre d'entree 10 traverse une partie 5A du carter 5, la partie exterieure de cet arbre 10 etant The rack 6 is engaged with a steering pigeon 9 (see FIG. 3), linked in rotation to an input shaft of the movement 10. The input shaft 10 passes through a part 5A of the casing 5, the external part of this tree 10 being
couplee a la colonne de direction avec volant de conduite (non representee). coupled to the steering column with steering wheel (not shown).
S'agissant ici d'une direction assistee electrique, celle-ci comprend encore un moteur electrique d'assistance 11, qui par l'intermediaire d'un As this is an electric power steering, it also includes an electric assistance motor 11, which by means of a
reducteur mecanique 12 agit ici au niveau du pigeon de direction 9. mechanical reducer 12 acts here at the level of the steering pigeon 9.
La partie de carter 5A, traversee par l'arbre d'entree 10, est ajustee de man i ere a attei ndre l'habitacle 3, ou du moi ns la pa ro i 4 l i m itrophe de cet habitacle 3, avec interposition d'un joint 16. L'arbre d'entree 10 atteint ainsi The casing part 5A, crossed by the input shaft 10, is adjusted so as to reach the passenger compartment 3, or from the bottom of the body to the adjacent limp of this passenger compartment 3, with interposition of a seal 16. The input shaft 10 thus reaches
l'habitacle 5, par une ouverture 13 menagee dans la paroi separatrice 4. the passenger compartment 5, through an opening 13 in the separating wall 4.
En se referent a la figure 2 et surtout a la figure 3, la partie de carter 5A presente, sur le cote de l'arbre d'entree 10, un alesage 14 qui la traverse sur toute son epaisseur, et qui debouche dans ltouverture 13, de sorte que l'interieur de ia partie de carter 5A, done l'interieur de la direction, est en Referring to Figure 2 and especially in Figure 3, the housing part 5A has, on the side of the input shaft 10, a bore 14 which passes through it over its entire thickness, and which opens into the opening 13 , so that the interior of the housing part 5A, therefore the interior of the steering, is in
communication avec l'habitacle 3, done avec ltexterieur. communication with the passenger compartment 3, therefore with the exterior.
Dans l'exemple illustre, un element d'obturation 15, en forme de pastille ou de tampon, en une matiere poreuse permeable a l'air mais hydrophobe, est mis en place dans l'alesage 14. La matiere constitutive de ['element d'obturation 15 peut etre une resine polymerique fluoree poreuse, telle que celle commercialisee sous la denomination "PERMEON" (marque In the example illustrated, a sealing element 15, in the form of a pellet or pad, made of a porous material permeable to air but hydrophobic, is placed in the bore 14. The material constituting the element obturation 15 may be a porous fluoropolymer resin, such as that marketed under the name "PERMEON" (brand
enregistree), ou toute autre matiere equivalente. registered), or any other equivalent matter.
La direction est ainsi rendue "respirante", c'est-a-dire qu'une circulation d'air est rendue possible entre l'interieur de la direction et l'exterieur, par l'alesage 14, et en mettant aussi a profit la communication habituellement existante entre les deux soufflets 8, cette direction restart toutefois etanche a lteau, et eventuellement aux poussieres ou autres particules solides, grace a ['element d'obturation 15 qui permet en particulier a cette direction de resister aux projections d'eau ou de liquides. La double fleche F1 de la figure 3 The steering is thus made "breathable", that is to say that an air circulation is made possible between the interior of the management and the exterior, by the bore 14, and also by taking advantage of the communication usually existing between the two bellows 8, this direction restarted, however watertight, and possibly dust or other solid particles, thanks to the shutter element 15 which in particular allows this direction to resist splashing water or liquids. The double arrow F1 in Figure 3
symbolise cette "respiration" de la direction. symbolizes this "breathing" of management.
Dans le cas d'une direction a realiser de facon particulierement economique, et si le debouche de l'alesage 14 se trouve dans une zone de l'habitacle 3 protegee de l'humidite, I'element d'obturation 15 peut etre In the case of a direction to be carried out in a particularly economical manner, and if the opening of the bore 14 is in a zone of the passenger compartment 3 protected from moisture, the shutter element 15 can be

Comme il va de soi, et comme il ressort de ce qui precede, I'invention ne se limite pas a la seule forme d'execution de cette direction a cremaillere qui a ete decrite ci-dessus d'exemple; elle en embrasse, au contrai re, toutes les variantes de real isati on et d' appl i catio n respectant le meme principe. C'est ainsi, notamment, que l'on ne s'eloignerait pas du cadre de ['invention: - en rempla,cant l'alesage 14 par tout conduit ou toute traversee equivalente, permettant la communication desiree; - en pla,cant ou non, dans cet alesage ou conduit analogue, un element d'obturation 15 de toute forme et en toute matiere appropriee, en fonction des exigences particulieres a chaque cas d'application (resistance a l'eau et/ou aux poussieres), cet element d'obturation pouvant etre retenu par tout moyen dans l'alesage ou conduit analogue; en mettant a profit, selon le type de direction concernee, toute partie de carter pouvant etre rapprochee de l'habitacle, en particulier le carter d'un capteur de couple, ou le carter du reducteur 12 dans le cas d'une direction a assistance electrique; en destinant le meme dispositif de "respiration" a des directions;a cremaillere de tous types, qu'il s'agisse d'une direction manuelle As is obvious, and as appears from the above, the invention is not limited to the only form of execution of this rack-and-pinion direction which has been described above by way of example; on the contrary, it embraces all variants of real isati on and appl i catio n respecting the same principle. Thus, in particular, that one would not depart from the framework of the invention: - in place of it, cant the bore 14 by any conduit or any equivalent crossing, allowing the desired communication; - In place, cant or not, in this bore or similar conduit, a closure element 15 of any shape and in any suitable material, according to the requirements specific to each application case (water resistance and / or dust), this sealing element can be retained by any means in the bore or similar conduit; taking advantage, depending on the type of steering involved, any part of the casing which can be brought closer to the passenger compartment, in particular the casing of a torque sensor, or the casing of the reduction gear 12 in the case of power-assisted steering electric; by using the same "breathing" device for directions; rack and pinion of all types, whether it is a manual direction
