ROUE PHONIQUE, PROCÉDÉ DE FABRICATION ET DISPOSITIFPHONIC WHEEL, MANUFACTURING METHOD, AND DEVICE

ROTATIF ÉQUIPÉ D’UNE TELLE ROUEROTARY EQUIPPED WITH SUCH A WHEEL

Domaine techniqueTechnical area

L’invention se rapporte au domaine des chaînes de transmission de véhicule automobile et concerne plus particulièrement un dispositif d’une chaîne de transmission de véhicule automobile qui est équipé d’une roue phonique destinée à être disposée en regard d’un capteur.The invention relates to the field of motor vehicle transmission chains and relates more particularly to a device of a motor vehicle transmission chain which is equipped with a tone wheel intended to be placed facing a sensor.

Arrière-plan technologiqueTechnological background

Les documents DE102008023869 et DE102011102001 divulguent un volant primaire d’un double volant amortisseur équipé d’une roue phonique. La roue phonique comporte un flasque d’orientation radiale qui est fixé contre le couvercle du volant primaire et une pluralité de doigts qui s’étendent axialement depuis la périphérie externe du flasque, tout autour d’une jupe cylindrique du volant primaire. Ainsi, lorsque le double volant amortisseur est entraîné en rotation, les doigts génèrent des variations de champ magnétique susceptibles d’être détectées par un capteur disposé en regard de la roue phonique. Un tel capteur est ainsi apte à délivrer un signal représentatif de la position angulaire et/ou de la vitesse de la roue phonique.Documents DE102008023869 and DE102011102001 disclose a primary flywheel of a double damping flywheel equipped with a tone wheel. The tone wheel has a flange of radial orientation which is fixed against the cover of the primary flywheel and a plurality of fingers which extend axially from the external periphery of the flange, all around a cylindrical skirt of the primary flywheel. Thus, when the double damping flywheel is rotated, the fingers generate variations in the magnetic field capable of being detected by a sensor placed opposite the tone wheel. Such a sensor is thus able to deliver a signal representative of the angular position and / or of the speed of the tone wheel.

Lors de la fabrication il est nécessaire de faire subir une déformation plastique aux doigts de la roue phonique. Les doigts doivent se tenir en parallèle à l’axe de rotation.During manufacture, it is necessary to subject the fingers of the tone wheel to plastic deformation. The fingers should stand parallel to the axis of rotation.

L’étape finale du procès de fabrication est un roulement. Afin de tenir compte de l’élasticité du matériau, il est nécessaire de laisser une espace entre la jupe cylindrique et les doigts. Cependant en même temps il faut aussi éviter des déformations des doigts lors du montage ou d’un transport éventuel. Deux solutions sont donc proposées dans l’art antérieur :The final step in the manufacturing process is a rollover. In order to take into account the elasticity of the material, it is necessary to leave a space between the cylindrical skirt and the fingers. However at the same time it is also necessary to avoid deformations of the fingers during assembly or possible transport. Two solutions are therefore proposed in the prior art:

Soit ajouter après roulement un voile de protection. Il faut alors une pièce supplémentaire. Mais une pièce supplémentaire engendre aussi une phase de montage supplémentaire, donc des coûts et du temps de production supplémentaires.Or add a protective veil after rolling. An additional room is then required. But an additional part also generates an additional assembly phase, therefore additional costs and production time.

Soit usiner sur la jupe cylindrique une excroissance radiale qui empêchera toute déformation indésirable des doigts, suite à des impacts latéraux éventuels.Either machine a radial protuberance on the cylindrical skirt which will prevent any undesirable deformation of the fingers, due to possible lateral impacts.

Mais comme on a pu voir ci-dessus les conséquences sont un aboutissement insatisfaisant concernant la déformation plastique nécessaire des doigts, dû à l’élasticité du matériau.But as we have seen above the consequences are an unsatisfactory outcome concerning the necessary plastic deformation of the fingers, due to the elasticity of the material.

InventionInvention

L’invention vise une solution aux problèmes précités :The invention aims to solve the above problems:

Une roue phonique pour dispositif de chaîne de transmission de véhicule comportant une couronne annulaire qui s’étend axialement, la couronne annulaire comportant des doigts qui s’étendent parallèlement à l’axe (X) de ladite roue, et lesdits doigts comportent au moins un relief.A tone wheel for a vehicle transmission chain device comprising an annular crown which extends axially, the annular crown comprising fingers which extend parallel to the axis (X) of said wheel, and said fingers comprise at least one relief.

Au sens de la présente demande :Within the meaning of this request:

- « axialement >> signifie « parallèlement à l’axe de la roue >>,- "axially" means "parallel to the axis of the wheel",

- « radialement >> signifie « le long d’un axe appartenant à un plan orthogonal à l’axe de rotation de la roue et coupant cet axe de rotation >>.- "radially" means "along an axis belonging to a plane orthogonal to the axis of rotation of the wheel and intersecting this axis of rotation".

La roue phonique, modifiée ainsi, comporte donc plusieurs avantages :The tone wheel, thus modified, therefore has several advantages:

La déformation des doigts est facilitée sans phase de montage supplémentaire.The deformation of the fingers is facilitated without additional mounting phase.

Le risque de déformation des doigts pendant le montage et le transport est limité.The risk of deformation of the fingers during assembly and transport is limited.

Figures 11a et b sont des vues de différentes roues phoniques selon l’inventionFigures 11a and b are views of different tone wheels according to the invention

Les figures 1 et 2a montrent une roue phonique (10), comportant en outre :Figures 1 and 2a show a tone wheel (10), further comprising:

- une jupe cylindrique (14) qui est mobile en rotation par rapport à l’élément rotatif et qui est interposé axialement entre la portion formant couvercle (11) et la portion radiale de l’élément rotatif ; et- A cylindrical skirt (14) which is movable in rotation relative to the rotary element and which is axially interposed between the cover portion (11) and the radial portion of the rotary element; and

- des organes élastiques (15) qui sont logés dans la chambre annulaire (16) et qui sont chacun interposés circonférentiellement entre une patte d’appui solidaire en rotation du voile et un siège d’appui solidaire en rotation de l’élément rotatif.- elastic members (15) which are housed in the annular chamber (16) and which are each interposed circumferentially between a support tab integral in rotation with the web and a support seat integral in rotation with the rotary element.

La jupe cylindrique (14) comporte des excroissances radiales (2). Le contact permanent entre les doigts (12) de la roue phonique (10) et le volant primaire (19) crée une liaison rigide et protège les doigts (12) contre des chocs frontaux et latéraux. Les doigts (12) sont ainsi protégés contre des déformations indésirables lors du montage ou du transport.The cylindrical skirt (14) has radial protuberances (2). The permanent contact between the fingers (12) of the tone wheel (10) and the primary flywheel (19) creates a rigid connection and protects the fingers (12) against frontal and lateral impacts. The fingers (12) are thus protected against undesirable deformations during assembly or transport.

Près de la courbure (17) à la base des doigts (12) se trouve le relief (1), qui facilite le pliage des doigts.Near the curvature (17) at the base of the fingers (12) is the relief (1), which facilitates the bending of the fingers.

There is a margin between the fingertip (3) and the radial protrusion (2) of the cylindrical skirt. In addition to the relief, this allows the rolling capacity to be increased during the finalization of the phonic wheel manufacturing process , while avoiding involuntary deformation of the finger (12).

La figure 6 représente un autre mode de réalisation de l’invention. La profondeur du relief est augmentée, elle varie de 1/3 à 2/3 de l'épaisseur du doigt (12).
