Description
La présente invention concerne une masselotte d'équilibrage dynamique d'un organe tournant et notamment pour l'équilibrage d'un organe de transmission de véhicule automobile. The present invention relates to a weight for dynamic balancing of a rotating member and in particular for balancing a transmission member of a motor vehicle.
Afin notamment de réduire le poids des transmissions, il a été proposé de réaliser divers composants de ces transmissions, qui étaient préalablement réalisés en métal, en matériau composite synthétique. In particular in order to reduce the weight of the transmissions, it has been proposed to produce various components of these transmissions, which were previously made of metal, of synthetic composite material.
Un exemple de cette nouvelle conception est décrit et représenté dans le document EP-A-0335781 qui illustre un corps de joint de transmission de structure composite synthétique dont l'enveloppe externe comporte au moins une portion de surface périphérique dont la matrice est en matériau synthétique à base de résine thermoplastique. An example of this new design is described and represented in document EP-A-0335781 which illustrates a transmission joint body of synthetic composite structure, the external envelope of which comprises at least one portion of peripheral surface, the matrix of which is of synthetic material. based on thermoplastic resin.
L'équilibrage dynamique d'une transmission de véhicule automobile, ou d'une portion de celle-ci, s'effectue sur un banc d'équilibrage en venant fixer sur au moins un composant de la transmission, une ou plusieurs masselottes d'équilibrage dynamique selon une technique connue. Dynamic balancing of a motor vehicle transmission, or a portion of it, is carried out on a balancing bench by fixing one or more balancing weights on at least one component of the transmission. dynamic according to a known technique.
Lorsque, selon l'état de la technique, les différents composants de la transmission sont métalliques, la fixation de chaque masselotte d'équilibrage peut être réalisée par sertissage mécanique ou par soudage de chaque masselotte qui est constituée par une simple masse pesante métallique. When, according to the state of the art, the various components of the transmission are metallic, the fixing of each counterweight can be carried out by mechanical crimping or by welding of each counterweight which is constituted by a simple heavy metal mass.
Le métal de la masse pesante est généralement choisi pour ses propriétés de soudabilité. The metal of the heavy mass is generally chosen for its weldability properties.
La réalisation du composant qui reçoit habituellement les masselottes d'équilibrage en matériau synthétique ne permet pas d'y fixer directement et de manière fiable une masse pesante métallique selon les techniques classiques. The production of the component which usually receives the balancing weights made of synthetic material does not allow a heavy metal mass to be fixed directly and reliably therein according to conventional techniques.
Afin de remédier à cet inconvénient, la présente invention propose une masselotte d'équilibrage pour un organe tournant comportant une surface périphérique en matériau synthétique à base de résine thermoplastique, caractérisée en ce qu'elle comporte au moins une partie en matière thermoplastique qui est prévue pour être fixée par soudage sur la surface périphérique de l'organe. In order to overcome this drawback, the present invention provides a balancing weight for a rotating member comprising a peripheral surface of synthetic material based on thermoplastic resin, characterized in that it comprises at least one part made of thermoplastic material which is provided to be fixed by welding on the peripheral surface of the member.

On reconnaît à la figure 1 un corps de joint de transmission 10 dont l'enveloppe 12, conformément aux enseignements du document EP-A-0335781 est réalisée en matériau synthétique et comporte par exemple une matrice en matière thermoplastique renforcée le cas échéant de fibres ou de particules. Recognizing in Figure 1 a transmission joint body 10 whose casing 12, in accordance with the teachings of document EP-A-0335781 is made of synthetic material and comprises for example a matrix of thermoplastic material reinforced where appropriate with fibers or of particles.
Afin de réaliser l'équilibrage dynamique d'un tel corps de joint de transmission, ou d'une partie d'une ligne de transmission à laquelle est incorporé ce corps de joint de transmission, il est proposé d'utiliser une masselotte d'équilibrage 14 telle qu'elle est illustrée aux figures 1 à 3. In order to carry out dynamic balancing of such a transmission joint body, or of a part of a transmission line in which this transmission joint body is incorporated, it is proposed to use a balancing weight 14 as illustrated in FIGS. 1 to 3.
La masselotte 14 comporte une masse pesante d'équilibrage 16 réalisée ici sous la forme d'une plaquette métallique et, conformément aux enseignements de l'invention, une partie de fixation 18 en matière thermoplastique. The counterweight 14 comprises a heavy balancing mass 16 produced here in the form of a metal plate and, in accordance with the teachings of the invention, a fixing part 18 made of thermoplastic material.
Dans le premier mode de réalisation illustré aux figures 1 à 3, la partie de fixation 18 est illustrée sous la forme d'un pion ou insert en matière thermoplastique qui est reçu dans un trou 20 formé sensiblement au centre de la plaquette métallique 16. In the first embodiment illustrated in FIGS. 1 to 3, the fixing part 18 is illustrated in the form of a peg or insert of thermoplastic material which is received in a hole 20 formed substantially in the center of the metal plate 16.
La fixation de la masselotte 14 sur la surface périphérique externe 13 de l'enveloppe 12 est réalisée par soudage des matières thermoplastiques compatibles constituant la matrice de l'enveloppe 12 et l'insert de fixation 18. The weight 14 is fixed to the external peripheral surface 13 of the casing 12 by welding the compatible thermoplastic materials constituting the matrix of the casing 12 and the fixing insert 18.
Il est ainsi possible de procéder à la fixation des masselotte d'équilibrage au point souhaité du corps de joint de transmission 10 par une opération de thermosoudage de l'insert 18 sur la surface périphérique externe 13 du corps de joint 12, la fusion partielle des matières en contact permettant d'une part d'assurer la fixation rigide de la masselotte 14 et, d'autre part, de s'assurer que la plaquette métallique 16 est correctement positionnée à proximité de la surface 13. It is thus possible to fix the balancing weights at the desired point of the transmission joint body 10 by a heat-sealing operation of the insert 18 on the external peripheral surface 13 of the joint body 12, the partial melting of the materials in contact making it possible on the one hand to ensure the rigid fixing of the counterweight 14 and, on the other hand, to ensure that the metal plate 16 is correctly positioned near the surface 13.
Initialement, c'est-à-dire avant l'opération de soudage de la masselotte 14, l'insert ou pion 18 peut se présenter sous la forme d'une tête élargie 20 et d'un corps de section constante 22 correspondant aux dimensions du trou 20, la forme élargie de la partie inférieure 24 résultant de l'opération de soudage. Initially, that is to say before the welding operation of the counterweight 14, the insert or pin 18 may be in the form of an enlarged head 20 and a body of constant section 22 corresponding to the dimensions of the hole 20, the enlarged shape of the lower part 24 resulting from the welding operation.
Dans la variante de réalisation illustrée à la figure 4, la masselotte 14 est également constituée d'une plaquette métallique 16 qui est entièrement enrobée par un revêtement en matière thermoplastique 18 dont la face inférieure 24 est fixée par thermosoudage sur la surface externe 13. In the variant embodiment illustrated in FIG. 4, the counterweight 14 also consists of a metal plate 16 which is entirely coated with a coating of thermoplastic material 18, the lower face 24 of which is fixed by heat sealing on the external surface 13.
Ce mode de réalisation a pour avantage de protéger la plaquette métallique 16 contre les phénomènes de corrosion. This embodiment has the advantage of protecting the metal plate 16 against corrosion phenomena.
Enfin, dans le mode de réalisation illustré aux figures 5 et 6, la plaquette métallique 16 est entourée par deux ceintures en matériau thermoplastique 18A et 18B reçues dans des encoches complémentaires formées dans la plaquette 16 et dont les faces inférieure 24A et 24B sont fixées à la surface externe 13 par soudage. Finally, in the embodiment illustrated in FIGS. 5 and 6, the metal plate 16 is surrounded by two belts of thermoplastic material 18A and 18B received in complementary notches formed in the plate 16 and whose lower faces 24A and 24B are fixed to the outer surface 13 by welding.
Toutes les techniques de soudage des matières thermoplastiques peuvent être utilisées sans sortir du cadre de l'invention. All the welding techniques for thermoplastics can be used without departing from the scope of the invention.
Le fait que la masse pesante 16 soit métallique permet notamment d'utiliser les techniques de soudage avec apport indirect de chaleur et par exemple le soudage par chauffage par induction de la masse métallique 16. The fact that the heavy mass 16 is metallic makes it possible in particular to use welding techniques with indirect heat input and for example welding by induction heating of the metallic mass 16.
La conception de la masselotte d'équilibrage selon l'invention permet également de choisir pour la masse pesante un métal de très haute densité, tel que par exemple du tungstène fritté, et ceci indépendamment de ses caractéristiques métallurgiques, et notamment de soudabilité. The design of the balancing weight according to the invention also makes it possible to choose for the heavy mass a metal of very high density, such as for example sintered tungsten, and this independently of its metallurgical characteristics, and in particular of weldability.
