Abstract

The device comprises a tube (3) with a curved portion (3c) and is mounted on the cable sheath (2). The internal diameter of the tubular element and its curvature are such that the sheath is held by simple deformation. The tube with the curved portion may be prolonged at its ends by rectilinear portions that are not parallel to each other. The tube also has a rectilinear entry portion (3a), a rectilinear exit portion (3b) coaxial to the entry portion and a central portion (3c). USE - Absorbing vibrations in sheathed cable.

Description

La présente invention a pour objet un dispositif pour amortir les vibrations auxquelles peut être soumis un câble à gaine.The present invention relates to a device for damping the vibrations to which a sheathed cable can be subjected.

Ce dispositif est caractérisé en ce qu'il est constitué par un élément tubulaire rigide qui comprend au moins une portion courbe et est monté sur la gaine, le diamètre interne de l'élément tubulaire et sa courbure étant tels que la gaine soit maintenue par simple déformation.This device is characterized in that it consists of a rigid tubular element which comprises at least one curved portion and is mounted on the sheath, the internal diameter of the tubular element and its curvature being such that the sheath is held by simple deformation.

L'élément tubulaire capte les vibrations imprimées au câble et les dissipe par suite de sa masse.The tubular element captures the vibrations impressed on the cable and dissipates them as a result of its mass.

Dans un mode de réalisation, l'élément tubulaire comprend une portion d'entrée rectiligne, une portion de sortie rectiligne coaxiale à la portion d'entrée et une portion centrale courbe se raccordant aux portions d'entrée et de sortie. Ce mode de réalisation est destiné à être monté sur une partie rectiligne du câble.In one embodiment, the tubular element includes a straight inlet portion, a straight outlet portion coaxial with the inlet portion and a curved central portion connecting to the inlet and outlet portions. This embodiment is intended to be mounted on a straight part of the cable.

Dans un autre mode de réalisation, l'élément tubulaire comprend une portion courbe prolongée à ses extrémités par des portions rectilignes non parallèles l'une à l'autre . Ce mode de réalisation améliore le cheminement du câble dans un angle.In another embodiment, the tubular element comprises a curved portion extended at its ends by rectilinear portions not parallel to each other. This embodiment improves the routing of the cable in a corner.

L'invention est particulièrement applicable au câble de commande d'accélérateur d'un véhicule automobile pour éviter une transmission dans l'habitacle des vibrations du groupe moto-propulseur.The invention is particularly applicable to the accelerator control cable of a motor vehicle to avoid transmission in the passenger compartment of the vibrations of the powertrain.

On a décrit ci-après, à titre d'exemples non limitatifs, des modes de réalisation du dispositif amortisseur selon l'invention avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en coupe d'un premier
mode de réalisation;
La Figure 2 est une vue en élévation d'un second
mode de réalisation;
La Figure 3 est une vue en élévation d'un
troisième mode de réalisation.Embodiments of the damping device according to the invention have been described below, by way of nonlimiting examples, with reference to the appended drawings in which
Figure 1 is a sectional view of a first
embodiment;
Figure 2 is an elevational view of a second
embodiment;
Figure 3 is an elevational view of a
third embodiment.

Aux dessins, on voit un câble constitué par une âme métallique 1 pouvant coulisser dans une gaine 2. Cette dernière peut être en matière plastique; elle peut également être formée par des spires d'acier enroulées sur un fourreau en matière plastique, telle que le nylon.In the drawings, we see a cable consisting of a metal core 1 which can slide in a sheath 2. The latter can be made of plastic; it can also be formed by turns of steel wound on a plastic sheath, such as nylon.

Un dispositif amortisseur de vibrations 3 est monté sur le câble 1-2. A la Figure 1, il est monté sur une partie initialement rectiligne du câble et est constitué par un tube comprenant une portion d'entrée rectiligne 3a, une portion de sortie rectiligne 3b coaxiale à la portion 3a et une portion centrale courbe 3c se raccordant aux portions rectilignes 3a et 3b par des portions courbes 3d et 3e dont la courbure est inverse de celle de la portion 3c; le tube est symétrique par rapport à un plan perpendiculaire à l'axe des portions 3a et 3b.A vibration damping device 3 is mounted on the cable 1-2. In FIG. 1, it is mounted on an initially rectilinear part of the cable and is constituted by a tube comprising a rectilinear inlet portion 3a, a rectilinear outlet portion 3b coaxial with the portion 3a and a central curved portion 3c connecting to the rectilinear portions 3a and 3b by curved portions 3d and 3e whose curvature is opposite to that of the portion 3c; the tube is symmetrical with respect to a plane perpendicular to the axis of the portions 3a and 3b.

La mise en place du dispositif se fait en y faisant glisser la gaine 2 avec son câble 1; la gaine se déforme en venant au contact en 4d et 4e avec les portions 3d et 3e et en 4c avec la portion 3c, cette portion 4c étant située à l'opposé des portions 4d et 4e par rapport à l'axe du câble.The device is put in place by sliding the sheath 2 therewith with its cable 1; the sheath deforms by coming into contact in 4d and 4th with the 3d and 3rd portions and in 4c with the portion 3c, this portion 4c being located opposite the portions 4d and 4e with respect to the axis of the cable.

Le mode de réalisation de la Figure 2 est semblable dans ses grandes lignes à celui de la Figure 1, mais l'une des portions d'extrémité 3a et 3b porte une masse auxiliaire rapportée 5. En variante, cette portion d'extrémité pourrait présenter une épaisseur supérieure à celle du restant de l'élément tubulaire. The embodiment of Figure 2 is broadly similar to that of Figure 1, but one of the end portions 3a and 3b carries an auxiliary auxiliary mass 5. Alternatively, this end portion could have a thickness greater than that of the remainder of the tubular element.

Dans le mode de réalisation de la Figure 3, le dispositif 6 est constitué par un tube dont la partie centrale Ga est en arc de cercle prolongée à ses extrémités par des portions rectilignes 6b et 6c non parallèles l'une à l'autre.In the embodiment of Figure 3, the device 6 is constituted by a tube whose central part Ga is in an arc extended at its ends by rectilinear portions 6b and 6c not parallel to each other.

Ainsi, l'invention permet de placer et de fixer facilement et rapidement une masse donnée en un endroit approprié du câble.Thus, the invention makes it possible to easily and quickly place and fix a given mass at an appropriate location on the cable.

Il va de soi que la présente invention ne doit pas être considérée comme limitée aux trois modes de réalisation décrits et représentés mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the three embodiments described and shown but, on the contrary, covers all variants thereof.
