Abstract
Description
ta présente invention a pour objet un soufflet pour joint homocinétique muni d'une valve à lèvre dspo- sée à proximité de la zone de montage du soufflet sur le demi-arbre. The subject of your present invention is a bellows for constant velocity joint provided with a lip valve placed close to the zone for mounting the bellows on the half-shaft.
I1 est connu, depuis longtemps, que les soufflets actuellement utilisés présentent l'inconvénient de subir des appels d'air en fonctionnement, ce qui crée des déformations qui réduisent la durée qu'on peut obtenir de ces soufflets. I1 has long been known that the bellows currently used have the drawback of undergoing air draws in operation, which creates deformations which reduce the duration that can be obtained from these bellows.
Ces inconvénients ont par conséquent pour effet, en premier lieu, de compromettre l'intégrité du soufflet et de porter préjudice à son fonctionnement et, en deuxième lieu, de compromettre l'intégrité du joint et d'entraîner sa détérioration prématurée. These drawbacks therefore have the effect, firstly, of compromising the integrity of the bellows and of prejudicing its operation and, secondly, of compromising the integrity of the seal and of causing its premature deterioration.
Afin d'éliminer les inconvénients précités, la présente invention se propose de réaliser un soufflet pour joint homocinétique caractérisé en ce qu'il comprend une valve à livre disposée à proximité de la zone de montage du soufflet sur le demi-arbre, de manière à éviter la sortie de la graisse et à permettre l'entrée de l'air lorsqu'il se crée une dépression à l'intérieur du soufflet. In order to eliminate the aforementioned drawbacks, the present invention proposes to produce a bellows for constant velocity joint characterized in that it comprises a book valve disposed near the zone for mounting the bellows on the half-shaft, so as to avoid the exit of the grease and allow the entry of air when a vacuum is created inside the bellows.
En outre, plusieurs rainures axiales et/ou plusieurs trous, convenablement pratiqués, mettent la chambre située en avant de la valve à livre en communication avec l'atmosphère. In addition, several axial grooves and / or several holes, suitably made, put the chamber located in front of the book valve in communication with the atmosphere.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une vue en coupe du soufflet objet de l'invention avec des trous convenablement pratiqués entre la zone de montage et la valve à lèvre
la figure 2 est une vue en coupe du soufflet selon l'invention, avec des rainures axiales convenablement pratiquées sur la zone de montage sur le demi-ar bre
la figure 3 est une vue en coupe selon la ligne
A-A de la figure 2.Other characteristics and advantages of the invention will appear during the description which follows, of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is a sectional view of the bellows object of the invention with holes suitably formed between the mounting area and the lip valve
Figure 2 is a sectional view of the bellows according to the invention, with axial grooves suitably formed on the mounting area on the half-shaft
Figure 3 is a sectional view along the line
AA in Figure 2.
Sur la figure 1, on a indiqué en C un soufflet, des trous traversants convenablement pratiqués entre la zone de montage 3 et la valve à lèvre 4 du soufflet C, en 5 et 5a, on a indiqué des ondulations qui caractérisent le profil du soufflet C disposé sur le demi-arbre, non représenté sur le dessin. In FIG. 1, there has been indicated at C a bellows, through holes suitably formed between the mounting zone 3 and the lip valve 4 of bellows C, at 5 and 5a, corrugations which characterize the profile of the bellows have been indicated. C arranged on the half-shaft, not shown in the drawing.
La valve à lèvre 4 est pratiquée, à l'intérieur du soufflet C, de façon à éviter la sortie de la graisse et à permettre en outre l'entrée de l'air lorsqu'il se crée une dépression à l'intérieur du soufflet. The lip valve 4 is made, inside the bellows C, so as to avoid the exit of the grease and in addition to allow the entry of air when a vacuum is created inside the bellows .
tes trous 2 et 2a d'entrée et de sortie de l'air mettent la chambre située en avant de la valve à lèvre 4 en communication avec l'atmosphère. your air inlet and outlet holes 2 and 2a place the chamber located in front of the lip valve 4 in communication with the atmosphere.
Sur la figure 2, on a indiqué par les mêmes numéros de référence les caractéristiques de la présente invention qui ont été décrites sur la figure 1, avec la seule différence consistant dans la zone de montage 3 du soufflet sur le demi-arbre, dans laquelle on a convenablement pratiqué des rainures axiales, qui sont représentées sur le dessin par au moins l'une d'elles, la rainure 2b, en remplacement des trous 2 et 2a, ces rainures assurant la même fonction que celle qui a été décrite plus haut à propos des trous 2 et 2a décrits sur la figure 1. In FIG. 2, the characteristics of the present invention have been indicated by the same reference numbers, which have been described in FIG. 1, with the only difference consisting in the mounting zone 3 of the bellows on the half-shaft, in which axial grooves have been suitably practiced, which are represented in the drawing by at least one of them, the groove 2b, replacing the holes 2 and 2a, these grooves ensuring the same function as that which has been described above about the holes 2 and 2a described in figure 1.
Sur la figure 3, on a indiqué en 1, 2 et 3 des rainures axiales, d'entrée et de sortie de l'air, pratiquées sur la zone 3 de montage sur le demi-arbre et qui servent à mettre la chambre -située en avant de la valve à lèvre 4 en communication avec l'atmosphère. In Figure 3, there are indicated in 1, 2 and 3 axial grooves, air inlet and outlet, made on the mounting area 3 on the half-shaft and which serve to put the chamber -located in front of the lip valve 4 in communication with the atmosphere.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif gui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described by way of non-limiting example without departing from the scope of the invention.
