Abstract

Motion transmission linkage 6, especially for operating a gear box. This linkage is characterised in that it includes, over a portion of its length, an elastic filter sleeve 1. This sleeve is advantageously engaged via its ends in two tubular ends 7 of the linkage 6, which are thereby connected together; it can include a rigid core 2 enveloped in an elastic jacket 3.

Description

TRINGLE DE TRANSMISSION DE MOUVEMENT
La présente invention concerne une tringle de transmission de mouvement, notamment pour commande de boîte de vitesses.MOTION TRANSMISSION ROD
The present invention relates to a motion transmission rod, in particular for gearbox control.

Pour éviter la transmission des vibrations de la boîte de vitesses au levier de commande, on peut utiliser des liaisons par câbles, ou l'on peut disposer un joint filtrant à l'extrémité de la tringle de transmission, mais ces solutions sont coûteuses. To avoid transmission of vibrations from the gearbox to the control lever, cable connections can be used, or a filter gasket can be placed at the end of the transmission rod, but these solutions are expensive.

Le but de la présente invention est d'apporter une autre solution à ce problème, qui soit d'un montage simple et peu coûteuse à fabriquer, tout en respectant les impératifs d'encombrement. The object of the present invention is to provide another solution to this problem, which is a simple assembly and inexpensive to manufacture, while respecting the space requirements.

A cet effet, une tringle conforme à l'invention est caractérisée en ce qu'elle comporte, sur une partie de sa longueur, un manchon filtrant élastique, ce manchon étant avantageusement engagé par ses extrémités dans deux extrémités tubulaires de la tringle, qui se trouvent ainsi raccordées l'une à l'autre. To this end, a rod according to the invention is characterized in that it comprises, over part of its length, an elastic filter sleeve, this sleeve being advantageously engaged by its ends in two tubular ends of the rod, which are thus connected to each other.

Ce manchon comportera généralement une âme rigide enrobée d'un revêtement élastique, cette âme étant constituée par exemple par une barre à section rectangulaire ou par un tube à section ronde. This sleeve will generally comprise a rigid core coated with an elastic coating, this core being constituted for example by a bar with rectangular section or by a tube with round section.

Pour faire en sorte que la tringle transmette les déplacements du levier avec précision, tout en filtrant efficacement les vibrations, elle pourra encore se caractériser en ce que ledit manchon présente transversalement différentes raideurs. To ensure that the rod transmits the movements of the lever with precision, while effectively filtering vibrations, it can also be characterized in that said sleeve has transversely different stiffnesses.

Cela pourra être obtenu par la forme de la section de l'âme rigide, et également par le fait que lesdites extrémités tubulaires de la tringle sont aplaties pour produire le serrage dudit manchon. This can be obtained by the shape of the section of the rigid core, and also by the fact that said tubular ends of the rod are flattened to produce the tightening of said sleeve.

Deux modes d'exécution de l'invention vont maintenant être décrits à titre d'exemples nullement limitatifs, avec référence aux figures du dessin annexé dans lequel
- la figure 1 est une vue en coupe axiale du manchon filtrant avant montage dans la tringle, selon la ligne I-I de la figure 2
- la figure 2 est une vue en bout du manchon filtrant
- la figure 3 est une vue de profil d'une tringle de commande de boîte de vitesses équipée, conformément à l'invention, avec le manchon des figures 1 et 2
- la figure 4 est une vue en plan de cette tringle, avec coupe axiale partielle au niveau du manchon filtrant
- la figure 5 est une vue à plus grande échelle de la partie coupée de la figure 4
- la figure 6 est une vue en coupe axiale d'une variante de manchon filtrant selon la ligne VI-VI de la figure 7 ; et
- la figure 7 est une vue en bout de ce manchon filtrant.Two embodiments of the invention will now be described by way of non-limiting examples, with reference to the figures in the appended drawing in which
- Figure 1 is an axial sectional view of the filter sleeve before mounting in the rod, along line II of Figure 2
- Figure 2 is an end view of the filter sleeve
- Figure 3 is a side view of a gearbox control rod fitted, according to the invention, with the sleeve of Figures 1 and 2
- Figure 4 is a plan view of this rod, with partial axial section at the filter sleeve
- Figure 5 is an enlarged view of the cut part of Figure 4
- Figure 6 is an axial sectional view of a variant of the filter sleeve along line VI-VI of Figure 7; and
- Figure 7 is an end view of this filter sleeve.

Le manchon filtrant 1 des figures 1 et 2 comporte une âme rigide métallique pleine 2, à section rectangulaire, enrobée d'un revêtement élastique 3, par exemple en élastomère ou en caoutchouc. Ce revêtement présente en son milieu une gorge 4 et possède de part et d'autre de cette gorge une forme générale cylindrique ou analogue, avec deux méplats latéraux 5, ce qui permettra après montage d'obtenir des raideurs transversales différenciées, selon deux directions orthogonales entre elles et perpendiculaires à l'axe du manchon. The filter sleeve 1 of FIGS. 1 and 2 comprises a rigid solid metallic core 2, of rectangular section, coated with an elastic coating 3, for example made of elastomer or rubber. This coating has in its middle a groove 4 and has on either side of this groove a generally cylindrical shape or the like, with two lateral flats 5, which will allow after assembly to obtain differentiated transverse stiffnesses, in two orthogonal directions between them and perpendicular to the axis of the sleeve.

A la figure 3 on a référencé globalement en 6 une tringle de commande tubulaire. Cette tringle est sectionnée transversalement, et le manchon 1 est engagé dans les deux extrémités tubulaires 7 de la tringle, qui se trouvent ainsi raccordées l'une à l'autre. Ces deux extrémités sont ensuite aplaties (comme visible en comparant les figures 3 et 4), ce qui les solidarise parfaitement du manchon filtrant 1. La présence de la gorge 4 sur le revêtement d'élastomère 3 empêche la formation d'un bourrelet en saillie sur la surface de la tringle, entre les extrémités tubulaires 7. In FIG. 3, a tubular control rod has been generally referenced at 6. This rod is sectioned transversely, and the sleeve 1 is engaged in the two tubular ends 7 of the rod, which are thus connected to one another. These two ends are then flattened (as seen by comparing Figures 3 and 4), which perfectly secures them to the filter sleeve 1. The presence of the groove 4 on the elastomer coating 3 prevents the formation of a protruding bead on the surface of the rod, between the tubular ends 7.

Le manchon filtrant I des figures 6 et 7 peut avoir la même forme extérieure que le précédent, mais son âme pleine 2 est remplacée par une âme tubulaire 2'. The filter sleeve I of FIGS. 6 and 7 can have the same external shape as the previous one, but its solid core 2 is replaced by a tubular core 2 '.

On comprend que les différentes épaisseurs du revêtement élastique 3, combinées à l'aplatissement des extrémités tubulaires 7, permettra de conférer au manchon, après son montage dans la tringle, les raideurs transversales différenciées souhaitées ; la raideur axiale et la raideur torsionnelle pourront de même être réglées à volonté, en choisissant de façon appropriée les épaisseurs du revêtement d'élastomère ainsi que sa longueur.  It is understood that the different thicknesses of the elastic coating 3, combined with the flattening of the tubular ends 7, will make it possible to give the sleeve, after its mounting in the rod, the desired differentiated transverse stiffnesses; the axial stiffness and the torsional stiffness can likewise be adjusted at will, by appropriately choosing the thicknesses of the elastomer coating as well as its length.
