Description
L'invention concerne un ouvrant de véhicule.The invention relates to a vehicle opening.
L'invention concerne plus particulièrement un dispositif de calage en position fermée d'un ouvrant sur la caisse d'un véhicule, du type comportant une butée et un réceptacle de butée.The invention relates more particularly to a device in the closed position of an opening on the body of a vehicle, of the type comprising a stop and a receptacle of stop.
L'ouvrant d'un véhicule doit être équipé de dispositifs pour remplir trois fonctions.The opening of a vehicle shall be equipped with to fulfill three functions.
La première fonction est la butée en fin de course au « claquement », c'est à dire l'arrêt de l'ouvrant contre la caisse du véhicule, lorsque l'utilisateur referme l'ouvrant.The first function is the stop at the end of the race at "Slamming", ie stopping the opening against the cash register of the vehicle, when the user closes the door.
La seconde fonction est le maintien de l'ouvrant en position fermée contre la caisse pendant le roulage du véhicule.The second function is the maintenance of the opening in closed position against the body while driving the vehicle.
La troisième fonction est le traitement des phénomènes acoustiques de type bourdonnement ou tambourinement que provoquent les petits mouvements de l'ouvrant par rapport à la caisse du véhicule.The third function is the treatment of phenomena acoustic type buzzing or drumming that cause small movements of the opening relative to the vehicle body.
Généralement, les fonctions de butée et de maintien sont assurées par des dispositifs de butée en caoutchouc ou en matériau élastomère.Generally, the stop and hold functions are provided by rubber stop devices or elastomeric material.
Par contre, le traitement des phénomènes acoustiques est réalisé par des dispositifs annexes du type « gâche filtrée », ou du type comportant un élément insonorisant à feuille fusible, ou encore du type à masselotte(s).On the other hand, the treatment of acoustic phenomena is achieved by ancillary devices of the "waste" type "filtered", or of the type incorporating a sound-absorbing element fuse sheet, or the feeder type (s).
La mise en oeuvre de plusieurs dispositifs, pour réaliser les trois fonctions décrites ci-dessus, complique les opérations d'assemblage de l'ouvrant sur la caisse du véhicule, ce qui augmente le coût de fabrication du véhicule.The implementation of several devices, to achieve the three functions described above, complicates the operations assembly of the opening on the vehicle body, which increases the cost of manufacturing the vehicle.
L'invention vise à proposer un dispositif qui permette de remplir les trois fonctions à la fois, de manière économique.The aim of the invention is to propose a device which makes it possible to perform all three functions at once, economically.
Dans ce but, l'invention propose un dispositif de calage du type décrit précédemment, dans lequel la butée comporte une tige fixe qui guide en coulissement axial une tête d'appui, à l'encontre d'un élément élastique, caractérisé en ce que, lorsque la tête d'appui et la surface en vis-à-vis du réceptacle sont en appui axial, la tête d'appui et la surface en vis-à-vis du réceptacle sont en contact linéaire suivant une ligne continue, la tige, la butée et le réceptacle assurant une liaison sensiblement rigide selon la direction radiale entre l'ouvrant et la caisse du véhicule.For this purpose, the invention proposes a wedging device of the type described above, in which the abutment comprises a fixed rod which guides, in axial sliding, a bearing head, against an elastic element, characterized in that when the bearing head and the surface facing the receptacle are axially supported, the bearing head and the surface facing the receptacle are in linear contact along a continuous line, the rod , the abutment and the receptacle ensuring a substantially rigid connection in the radial direction between the opening and the vehicle body.

L'extrémité inférieure de l'organe de guidage est de forme tronconique convexe et elle est complémentaire de la surface tronconique concave du réceptacle. Dans ce document, le contact entre l'organe de guidage et le réceptacle est de nature surfacique : c'est un contact entre une surface tronconique convexe et une surface tronconique concave complémentaires. Ce document ne concerne pas un dispositif de calage mais un dispositif de verrouillage dans lequel il n'est pas prévu un contact suivant une ligne continue.We know certainly in the document WO9807594 a locking device in the closed position of a hood on the body of a vehicle.

The device locking device comprises a centering means in the form of an guide which is slidably mounted on the rod, against a spring, and which cooperates by axial support against an associated receptacle integral with the support. The lower end of the guide member is shaped convex frustoconical and is complementary to the frustoconical surface concave of the receptacle. In this document, the contact between the organ of guiding and the receptacle is of a surface nature: it is a contact between a convex frustoconical surface and a concave frustoconical surface complementary. This document does not concern a rigging device but a locking device in which it is not expected a contact following a continuous line.

d'un ouvrant 12 sur la caisse 14 d'un véhicule.FIG. 1 shows a
Pour simplifier la représentation, l'ouvrant 12 et la
caisse 14 ont été représentés partiellement sous la forme d'une
portion de tôle de chacun de ces éléments.To simplify the representation, the
Dans la suite de la description, on utilisera les termes « supérieur » et « inférieur » pour caractériser les éléments qui sont situés respectivement en haut et en bas sur les figures.In the remainder of the description, the terms "Superior" and "inferior" to characterize the elements that are located respectively at the top and bottom in the figures.
Le dispositif de calage 10 comporte une butée 16 sur
l'ouvrant 12 et un réceptacle de butée 18 sur la caisse 14.The
La butée 16 comporte une tête d'appui 20 et un patin
élastique 22 annulaires et coaxiaux d'axe X-X.The
Le patin élastique 22 est interposé entre une face
inférieure 24 de l'ouvrant 12 et une surface radiale annulaire
supérieure 26 de la tête d'appui 20.The
Le patin élastique 22 a la forme d'une rondelle et
comporte un orifice annulaire 28 de diamètre D1.The
La tête d'appui 20 comporte un tronçon supérieur
cylindrique 30 et un tronçon inférieur qui forme une portée
tronconique convexe 32, inclinée vers l'axe X-X et vers le bas.The
La tête d'appui 20 comporte aussi un alésage axial
supérieur 34 de même diamètre D1 que l'orifice annulaire 28 du
patin élastique 22, et un alésage axial inférieur 36 de diamètre
D2.The
Comme le diamètre D2 de l'alésage axial inférieur 36 est
plus grand que le diamètre D1 de l'alésage axial supérieur 34,
les deux alésages 34, 36 délimitent une surface radiale
d'épaulement 38 orientée vers le bas. As the diameter D2 of the lower
Le diamètre D3 de l'extrémité axiale inférieure 40 de la
portée tronconique convexe 32 est plus grand que le diamètre
D2 de l'alésage axial inférieur 36. Ainsi, l'extrémité axiale
inférieure 40 de la portée tronconique convexe 32 délimite avec
l'ouverture axiale inférieure 42 de l'alésage axial inférieur 36
une surface radiale annulaire 44.The diameter D3 of the lower
La surface radiale annulaire 44 doit être suffisamment
large pour permettre de rigidifier l'extrémité axiale inférieure 40
de la portée tronconique convexe 32. En effet, il faut éviter la
déformation de l'extrémité axiale inférieure 40 lorsqu'elle est en
contact avec la portée tronconique concave 60, pour ne pas
nuire à la rigidité radiale recherchée.The annular

inférieure 24 de l'ouvrant 12 au moyen d'une vis de guidage 46
qui est vissée dans un écrou 48.The

La tête de guidage 54 s'appuie axialement sur la surface
d'épaulement 38 de la tête d'appui 20 par sa surface d'appui
56.The
Comme la tête de guidage 54 et l'alésage axial inférieur
36 ont sensiblement le même diamètre D2, la tête de guidage
54 assure une liaison radiale rigide avec la tête d'appui 20, ce
qui empêche tout mouvement radial de la tête d'appui 20.As the
De plus, la tête de guidage 54 guide en coulissement
axial la tête d'appui 20 lorsque cette dernière comprime
axialement le patin élastique 22.In addition, the guide head 54 guides in sliding
Le réceptacle 18 est de forme sensiblement cylindrique
annulaire et il est coaxial à la butée 16 d'axe X-X. The
La face radiale supérieure 58 du réceptacle 18 comporte
une portée tronconique concave 60 d'axe X-X.The upper
L'angle au sommet de la portée tronconique concave 60
est plus important que l'angle au sommet de la portée
tronconique convexe 32 de la tête d'appui 20.The angle at the top of the concave
De plus, le diamètre D3 de l'extrémité axiale inférieure
40 de la portée tronconique convexe 32 est sensiblement égal
au diamètre intermédiaire Di de la portée tronconique concave
60.In addition, the diameter D3 of the lower
Ainsi, lorsque la tête d'appui 20 vient en appui axial
contre le réceptacle 18, la portée tronconique convexe 32 est
en contact linéaire avec la portée tronconique concave 60 au
niveau du diamètre intermédiaire Di.Thus, when the

et le réceptacle 18.Linear contact between the two
Le diamètre D4 de l'extrémité axiale inférieure 62 de la
portée tronconique concave 60 est plus grand que le diamètre
D5 de l'orifice annulaire 64 du réceptacle 18. Ainsi, l'extrémité
axiale inférieure 62 de la portée tronconique concave 60
délimite avec l'ouverture axiale supérieure 66 de l'orifice
annulaire 64 une surface d'appui radiale annulaire 68 orientée
vers le haut.The diameter D4 of the lower
Le réceptacle 18 est fixé sur la face supérieure 70 de la
caisse 14 par une vis de fixation 72 qui est vissée dans un
écrou 74.The
L'écrou 74 s'appuie axialement sur la face inférieure 76
de la caisse 14 par l'intermédiaire d'une rondelle d'appui 78.The
