Abstract
Description
"Contacteur de commande hydromécanique pour installation
de réglage d'éclairage b distance de phares de véhicules
automobiles."
L'invention concerne un contacteur de commande hydro-mécanique pour installations de réglage dléclairage à longue distance de phares de véhicules automobiles avec un piston à double effet coulissant dans un carter et présentant au moins un écrou fileté, et une broche, actionnable à la main, pourvued'un filetage extérieur, qui coopère avec le filetage de l'écrou, et qui est supportée dans le carter pour pouvoir tourner sans possibilité de déplacement axial, un élément A ressort étant prévu pour accroître le couple de rotation de la broche filetée."Hydromechanical control switch for installation
lighting control b distance of vehicle headlights
automobiles. "
The invention relates to a hydro-mechanical control switch for long-distance lighting control installations for motor vehicle headlights with a double-acting piston sliding in a casing and having at least one threaded nut, and one spindle, operable by hand. , provided with an external thread, which cooperates with the thread of the nut, and which is supported in the casing so as to be able to rotate without the possibility of axial displacement, a spring element being provided to increase the torque of the threaded spindle.
Bn vue de s opposer à un positionnement non prévu de la broche filetée, notamment dans le cas de secousses du véhicule automobile et, d'autre part, pour compenser les tolérances de fabrication des pièces coopérant entre elles, il est nécessaire que la broche filetée soit appliquée contre le carter avec une force égale à au moins 60 Newton en direction axiale. Cette force est obtenue, dans le cas de contacteurs de commande, par un dis- que ondulé interposé entre la broche filetée et le carter. Bn view of opposing an unforeseen positioning of the threaded spindle, in particular in the case of jolts of the motor vehicle and, on the other hand, to compensate for the manufacturing tolerances of the parts cooperating with each other, it is necessary that the threaded spindle is applied against the casing with a force equal to at least 60 Newton in the axial direction. This force is obtained, in the case of control switches, by a corrugated disc interposed between the threaded spindle and the casing.
L'utilisation d'un disque ondulé de ce genre dans ces contacteurs de commande exige, en fait, une faible dimension de construction en direction axiale et moins de dépense technique. Cependant, la constante d'élasticité relativement grande du disque ondulé donne lieu, le plus eouvent, à une force de ressort irrégulière qui compromet le fonctionnement du contacteur de commande. The use of a corrugated disc of this kind in these control switches requires, in fact, a small dimension of construction in the axial direction and less technical expense. However, the relatively large elastic constant of the corrugated disc gives rise, most often, to an irregular spring force which compromises the operation of the control switch.
La présente invention a pour objet un contacteur de commande du type décrit, caractérisé en ce que la broche est une broche filetée creuse et présente un épaulement axial intérieur, le carter étant pourvu d'une douille qui stavance dans la broche filetée creuse avec un épaulement axial intérieur, ment à ressort étant constitué par un ressort hélicotdal de compression qui est tendu entre l'épaulement axial de la broche filetée et lépaule- ment axial de la douille. The present invention relates to a control switch of the type described, characterized in that the pin is a hollow threaded pin and has an internal axial shoulder, the casing being provided with a socket which stavance in the hollow threaded pin with a shoulder axial internal, spring-loaded being constituted by a helical compression spring which is tensioned between the axial shoulder of the threaded spindle and the axial shoulder of the sleeve.
L'avantage de l'invention réside notamment en ce que le changement du contacteur de commande d'un disque ondulé en un ressort hélicoïdal de compression n'a pour conséquence qu'une faible dépense technique pour la modification de l'outillage de fabrication. The advantage of the invention lies in particular in that the change of the contactor for controlling a corrugated disc into a helical compression spring only results in a low technical expense for the modification of the manufacturing tool.
L'invention prévoit divers modes de réalisation avantageux. Il est prévu notamment que 1' épaulement axial de la broche filetée creuse a une forme bombée de telle sorte que l'appui du disque d 'acier sur la broche filetée est ponctuel. Cet appui ponctuel a pour conséquence que le déplacement relatif, lors de l'actionnement du contacteur de commande de manière volontaire, a lieu seulement entre cet épaulement axial bombé et le disque d'acier appliqué sur lui. The invention provides various advantageous embodiments. Provision is made in particular for the axial shoulder of the hollow threaded spindle to have a domed shape so that the support of the steel disc on the threaded spindle is punctual. This punctual support has the consequence that the relative movement, when the control switch is actuated on a voluntary basis, takes place only between this convex axial shoulder and the steel disc applied to it.
Un exemple de réalisation est représenté dans les desseins annexés et est expliqué dans la description ciaprès. Dans ces dessins :
- la figure i est une représentation schématique en perspective d'une disposition pour phare de véhicule automobile avec une installation de réglage de 1' éclai- rage à longue distance,
- la figure 2 est une vue en élévation latérale, coupée par moitié, d'un contacteur de commande, à échelle agrandie.An exemplary embodiment is shown in the appended drawings and is explained in the description below. In these drawings:
FIG. i is a schematic perspective representation of an arrangement for a headlight of a motor vehicle with an installation for adjusting the lighting at long distance,
- Figure 2 is a side elevational view, cut in half, of a control switch, on an enlarged scale.
L'installation de réglage d'éclairage à longue distance de phares de véhicule automobile représentée en figure 1, comprend une tringlerie hydro-mécanique 9, qui consiste essentiellement en un organe de commande 10 actionnable à la main, deux organes de réglage de position 12 et une conduite 14 qui relie chaque organe de réglage de position à l'organe de commande. L'organe de commande 10 et les organes de réglage 12 sont fixés sur des portions Il de la carrosserie du véhicule et du carter de phare. The installation for the long-distance lighting control of headlights of a motor vehicle shown in FIG. 1, comprises a hydro-mechanical linkage 9, which essentially consists of a control member 10 operable by hand, two position adjustment members 12 and a pipe 14 which connects each position adjusting member to the control member. The control member 10 and the adjustment members 12 are fixed to portions II of the vehicle body and of the headlight housing.
Chaque organe de réglage de position 12 est articulé, au moyen d'un poussoir 15 sur le réflecteur 13, lequel peut pivoter, autour d'un axe transversal horizontal 16, de quelques degrés angulaires suivant la double flèche 18, lorsqu'on agit sur un volant à main 17 pour déplacer ltor- gane de commande 10 suivant la double flèche 19.Each position adjustment member 12 is articulated, by means of a pusher 15 on the reflector 13, which can pivot, about a horizontal transverse axis 16, by a few angular degrees along the double arrow 18, when acting on a hand wheel 17 for moving the control organ 10 along the double arrow 19.
Le contacteur de commande 10 représenté en figure 2 possède un couvercle de fermeture 21 dans lequel est fixé par vis, de manière non représentée, un carter de cylindre 22 avec deux alésages cylindriques 23, et un couvercle de carter 20 accroché par crans. cintre le carter de cylindre 22 et le couvercle de fermeture 21 est tendue une membrane de partage 24, de telle sorte que sont formées une première et une seconde chambres de pression, chacune étant reliée par un raccord de branchement 28 à la conduite 14. The control switch 10 shown in Figure 2 has a closure cover 21 in which is fixed by screws, not shown, a cylinder housing 22 with two cylindrical bores 23, and a housing cover 20 hooked by notches. bends the cylinder casing 22 and the closure cover 21 is stretched a partition membrane 24, so that a first and a second pressure chamber are formed, each one being connected by a connection fitting 28 to the pipe 14.
Un écrou de déplacement de réglage 30, avec filetage 31, est monté pour pouvoir coulisser, dans le carter de cylindre 22, parallèlement à l'axe 29 et il présente deux pièces de fourche 33 qui coopèrent avec deux pistons de réglage 25. A partir du carter de cylindre 22, s'étend, coaxialement à l'axe 29, une douille 32 pourvue d'un alésage 34 et d'un étanchement axial intérieur 35. An adjustment displacement nut 30, with thread 31, is mounted in order to be able to slide, in the cylinder housing 22, parallel to the axis 29 and it has two fork parts 33 which cooperate with two adjustment pistons 25. From of the cylinder casing 22, extends, coaxial to the axis 29, a sleeve 32 provided with a bore 34 and an internal axial seal 35.
Une broche filetée, constituée comme broche creuse 27, est montée dans le couvercle de carter 20, de manière à pouvoir tourner autour de son axe, mais immobilisée contre un déplacement axial. La broche filetée creuse 27 est pourvue de plusieurs nervures 40 parallèles à l'axe et d'un fond convexe 41 qui forme un épaulement axial intérieur 39. BR outre, la broche 27 comporte un filetage ex- térieur 26, qui coopère avec un écrou fileté 31. A threaded spindle, constituted as a hollow spindle 27, is mounted in the casing cover 20, so as to be able to rotate around its axis, but immobilized against an axial displacement. The hollow threaded spindle 27 is provided with several ribs 40 parallel to the axis and with a convex bottom 41 which forms an internal axial shoulder 39. BR further, the spindle 27 has an external thread 26, which cooperates with a nut threaded 31.
La douille 32 du carter de cylindre 22 est guidée sur les nervures 40 et elle s'appuie, par l'intermé- diaire d'un disque 38, contre'l'épaulement axial 39 de la broche filetée creuse 27, de telle manière que soit réalisée une application ponctuelle du disque 38 contre l'épaulement 39. Un ressort de compression hélicoïdal 37 est monté entre l'épaulement axial 39 de la broche filetée creuse 27 et l'épaulement axial 35 de la douille 32, avec une tension préalable telle que le couple de rotation de la broche soit accru d'une manière prédéterminée. Le ressort hélicoïdal possède une rigidité telle qu'un actionnement du contacteur de commande, c'est-à-dire une rotation de la broche 27, conformément à la double flèche 19, ne provoque pas, même en cas de conditions non favorables, une torsion du ressort hélicoidal 37. Le disque 38 est constitué en métal, notamment en acier. The sleeve 32 of the cylinder housing 22 is guided on the ribs 40 and it is supported, by means of a disc 38, against the axial shoulder 39 of the hollow threaded spindle 27, so that a punctual application of the disc 38 is made against the shoulder 39. A helical compression spring 37 is mounted between the axial shoulder 39 of the hollow threaded pin 27 and the axial shoulder 35 of the sleeve 32, with a prior tension such that the spindle torque is increased in a predetermined manner. The helical spring has a rigidity such that an actuation of the control switch, that is to say a rotation of the spindle 27, in accordance with the double arrow 19, does not cause, even in unfavorable conditions, a torsion of the helical spring 37. The disc 38 is made of metal, in particular steel.
