Abstract

This gear lever collar for motor vehicles, which consists of a gaiter made from elastic material, comprises on those of its internal surfaces 11 and 12 which face in the sound-penetration direction 10 a great number of ribs or tabs 13 projecting a long way which are offset by 90 DEG from one another.

Description

L'invention concerne une manchette de levier de vitesse pour véhicules automobiles réalisée sous la forme d'un soufflet en matière élastique. The invention relates to a gear lever sleeve for motor vehicles produced in the form of a bellows made of elastic material.

On connatt déjà, par la DE-A-23 27 283, une manchette de levier de vitesses réalisée sous la forme d'un soufflet en matière élastique, qui doit assurer, en dehors de sa fonction normale d'étanchéité, également une fonction de ressort et une fonction d'atténuation des bruits. Cette manchette de levier de vitesses a une paroi très épaisse, comparativement à une manchette de levier de vitesses traditionnelle, de sorte que la matière élastique de la manchette du levier de vitesses peut assurer, d'une part la fonction de ressort et, d'autre part, en même temps, grâce à sa plus forte épaisseur de paroi, une bonne atténuation des bruits. We already know, from DE-A-23 27 283, a shifter sleeve made in the form of a bellows of elastic material, which must ensure, apart from its normal sealing function, also a function of spring and a noise reduction function. This gear lever sleeve has a very thick wall, compared to a traditional gear lever sleeve, so that the elastic material of the gear lever sleeve can, on the one hand, act as a spring and, on the other hand, at the same time, thanks to its greater wall thickness, good attenuation of noise.

Toutefois, cette manchette de levier de vitesses déjà connue présente l'inconvénient que l'effet de ressort qu'elle assure doit être surmonté par les mouvements de changements de vitesses du levier de vitesses et que, l'effort nécessaire pour cela peut être beaucoup plus important qu'on ne le désirerait aux basses températures et, lorsque la matière élastique est donc plus raide. However, this already known shifter sleeve has the disadvantage that the spring effect which it provides must be overcome by the gear shift movements of the gear lever and that the effort required for this can be much more important than you would like at low temperatures and when the elastic material is therefore stiffer.

La simplicité de la construction et la bonne atténuation des bruits sont donc compensées par un inconvénient gênant. The simplicity of the construction and the good attenuation of the noises are therefore compensated by an annoying drawback.

Le but de l'invention est donc de perfectionner une manchette de levier de vitesses du genre cité ci-dessus de manière qu'elle assure, d'une façon connue, une fonction élastique minimum mais qu'elle permette une atténuation des bruits considérablement améliorée comparativement aux manchettes de leviers de vitesses simples et à paroi mince. The object of the invention is therefore to improve a gear lever cuff of the kind mentioned above so that it provides, in a known manner, a minimum elastic function but that it allows a considerably improved noise attenuation. compared to the sleeves of thin and thin walled gear levers.

Cette invention a pour objet une manchette de levier. This invention relates to a lever cuff.

de vitesses qui a la forme d'un soufflet en matière plastique et dont les surfaces internes qui font face à la direction de pénétration des sons sont munies d'un grand nombre de nervures ou languettes fortement saillantes, décalées de 900 les unes par rapport aux autres.gear which has the shape of a plastic bellows and the internal surfaces of which face the direction of sound penetration are provided with a large number of highly protruding ribs or tongues, offset by 900 relative to the other.

Grâce à cette réalisation des plis de la manchette les ondes sonores qui entrent sont empêchées , par réflexion sur les nervures, de pénétrer dans l'habitacle du véhicule. Thanks to this embodiment of the folds of the cuff, the sound waves which enter are prevented, by reflection on the ribs, from entering the passenger compartment of the vehicle.

A la place du grand nombre de nervures, il est également possible de prévoir un grand nombre de bossages en forme de doigts. Instead of the large number of ribs, it is also possible to provide a large number of finger-shaped bosses.

De même il est avantageux de munir les surfaces considérées d'une matière textile par flocage électrostatique. Likewise, it is advantageous to provide the surfaces under consideration with a textile material by electrostatic flocking.

Les caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre. The characteristics and advantages of the invention will become apparent during the description which follows.

Sur les dessins annexés, donnés uniquement à titre d'exemple;
la Fig 1 est une coupe verticale d'une manchette de levier de vitesse selon l'invention ;
la Fig. 2 est une vue de dessus de l'une des surfaces internes de la manchette de levier de vitesse, prise dans le sens de la flèche II de la Fig. 1.
In the accompanying drawings, given only by way of example;
Fig 1 is a vertical section of a gear lever cuff according to the invention;
Fig. 2 is a top view of one of the internal surfaces of the gear lever sleeve, taken in the direction of arrow II in FIG. 1.

La manchette de levier de Vitesses 1 représentée sur la Fig. 1 présente de façon connue la forme d'un soufflet en matière élastique. The gear lever cuff 1 shown in FIG. 1 has in known manner the shape of a bellows of elastic material.

A l'intérieur de la manchette de levier de vitesses, se trouve un levier de vitesses 2 qui dans sa partie inférieure est agencé de manière à pouvoir osciller latéralement et dans la direction longitudinale grace à une articulation 3. Un ressort 4 ramène le levier de vitesses à sa position de point mort lorsque la marche arrière n'est pas enclenchée. Inside the gear lever sleeve, there is a gear lever 2 which in its lower part is arranged so that it can oscillate laterally and in the longitudinal direction thanks to a hinge 3. A spring 4 brings the lever gears to its neutral position when reverse gear is not engaged.

La manchette de levier de vitesses 7 comporte une partie tubulaire 5, une partie plissée en soufflet 6 et une partie de pied 7. La partie tubulaire 5 renferme le levier de vitesse 2 tandis que la partie plissée 6 entoure essentiellement la région de l'articulation 3 et du ressort 4 et que le pied 7 est montée sur une ouverture 8 de la tôle 9 du plancher à travers laquelle les ondes sonores provenant de la botte de 7vitesses du véhicule automobile, dont la direction est indiquée par des flèches 10, peuvent pénétrer dans la région de la manchette du levier de vitesses située dans l'habitacle du véhicule. The gear lever sleeve 7 comprises a tubular part 5, a pleated bellows part 6 and a foot part 7. The tubular part 5 encloses the gear lever 2 while the pleated part 6 essentially surrounds the region of the joint. 3 and the spring 4 and that the foot 7 is mounted on an opening 8 of the sheet metal 9 of the floor through which the sound waves from the boot of 7 gears of the motor vehicle, the direction of which is indicated by arrows 10, can penetrate in the region of the shifter cuff located in the passenger compartment of the vehicle.

Selon l'invention, les surfaces 11 de la partie tubulaire 5 et les surfaces 12 de la partie plissée 6 qui font face à la direction 10 de pénétration des sons sont garnies d'un grand nombre de nervures ou languettes 13 fortement saillantes , qui sont décalées de 900 les unes par rapport aux autres. According to the invention, the surfaces 11 of the tubular part 5 and the surfaces 12 of the pleated part 6 which face the direction 10 of sound penetration are provided with a large number of highly protruding ribs or tongues 13, which are offset by 900 from each other.

La disposition décalée de 900 est bien visible sur la Fig. 2. The offset arrangement of 900 is clearly visible in FIG. 2.

De manière analogue, des saillies en forme de tige peuvent être disposées avec un faible écartement è la place des nervures ou languettes 13, ou encore les surfaces peuvent être munies d'un flocage en matiere textile déposé par voie électrostatique. Similarly, rod-shaped protrusions can be arranged with a small spacing in place of the ribs or tongues 13, or else the surfaces can be provided with a flocking of textile material deposited electrostatically.

Les ondes sonores arrivant selon la direction 10 de pénétration des sons sont atténuées ou détruites par les nervures,languettes ou doigts composés d'une matière dlasti- que, d'une part par absorption et d1autrepart, par réflexion e dans une mesure suffisante pour qu'aucun bruit gênant ne soit plus transmis à l'habitacle. The sound waves arriving in the direction of penetration of the sounds are attenuated or destroyed by the ribs, tongues or fingers composed of a elastic material, on the one hand by absorption and on the other hand, by reflection and to a sufficient extent so that '' no annoying noise is transmitted to the passenger compartment.

Etant donné que la manchette de levier de vitesse 1 est constituée par un élément élastique à paroi mince, comme dans la technique antérieure, on a plus à crainre qu ' elle fasse obstacle aux efforts de changement de vitesse.  Since the gear lever sleeve 1 is constituted by an elastic element with a thin wall, as in the prior art, there is more reason to fear that it will obstruct the efforts of gear changing.
