Abstract

The invention relates to a transmission belt 1. The internal part of the belt 1 has a V section. The external part is toothed. Application: a first connection is provided between the groove pulleys 9 and 10. A second connection drives the toothed wheel 11. Particular case of a supercharging compressor 20 retrofitted to an internal combustion engine 16.

Description

La présente invention est relative à une courroie de transmie scion d'un type nouveau, destinée notamment à l'industrie mécanique, en particulier à l'équipement des mocteurs thermiques.The present invention relates to a scion transmission belt of a new type, intended in particular for the mechanical industry, in particular for equipping thermal engines.

On connait par exemple par la demande de brevet français 87.04.918, déposée le 3 Avril I987 au nom du présent demandeur pour: n Suralimenteur d'air pour moteurs à combustion i entrainement par courroie ", une transmission par courroie sans fin à section trapézoldale. Cette transmission connue est spécialement prévue pour équiper après coup un moteur thermique atmosphérique, en permettant d'y adapter un compresseur de suralimen- tation. We know for example by the French patent application 87.04.918, filed on April 3, I987 in the name of the present applicant for: n Air supercharger for combustion engines i belt drive ", an endless belt transmission with trapezoidal section This known transmission is specially designed to retrofit an atmospheric heat engine, making it possible to adapt a supercharging compressor to it.

En pratique, on constate que ce compresseur doit titre générale mengbn compresseur volumètrique dont le fonctionnement fait apparaître de micro-vibrations dans la courroie; ce qui peut éventuellement conduire à des glissements de plus ou moins grande amplitude.In practice, it can be seen that this compressor must generally have a volumetric compressor whose operation reveals micro-vibrations in the belt; which can eventually lead to slippages of greater or lesser amplitude.

La présente invention a pour but d'éviter ces inconvénients en réalisant une courroie de transmission à'un type nouveau, sus- ceptible de supprimer tout risque de glissement, mdme dans une transmission soumise à de micro-vibrations.The object of the present invention is to avoid these drawbacks by producing a transmission belt of a new type, capable of eliminating any risk of slipping, even in a transmission subjected to micro-vibrations.

Une courroie de transmission selon l'invention est une courroie
sans fin dont la partie intérieure possède une section trapézoidale, et elle est caractérisé en ce que sa partie extérieure, ou "dos de la courroie" est crantée pour coopérer avec au moins une roue crantée avec laquelle elle assure une liaison de transmission sans glissement.A transmission belt according to the invention is a belt
endless whose inner part has a trapezoidal section, and it is characterized in that its outer part, or "back of the belt" is notched to cooperate with at least one notched wheel with which it provides a transmission link without sliding.

Le dessin annexé, donné à titre d'éxemple non limitatif, permettra de mieux comprendre l'invention et les avantages qu'elle est susceptible de procurer.The appended drawing, given by way of nonlimiting example, will allow a better understanding of the invention and the advantages which it is likely to provide.

Fiff=zre 2: Est une vue de face d'une courroie selon l'invention assurant l'entrainement du -compresseur de suralimentation sur un moteur thermique. Fiff = zre 2: Is a front view of a belt according to the invention ensuring the drive of the supercharger on a heat engine.

Figures: montre en perspective et coupe partielle la structure de cette transmission. Figures: shows in perspective and partial section the structure of this transmission.

Onxreprésenté sus les dessins une courroie sans fin (I) selon l'invention, qui présente les caractéristiques suivantes: -Sa partie intérieure (2) présente une section trapézoïdale (3) qui définit deux flancs obliques (4) situés de part et d'autre d'un fond plat (5). The drawings show an endless belt (I) according to the invention, which has the following characteristics: -Its interior part (2) has a trapezoidal section (3) which defines two oblique sides (4) located on either side another of a flat bottom (5).

-Sa partie extérieure (6) ou"dos de la courroie" est crantée, c'est-à-dire que le long de ce dos (6) alternent des rainures transversales (7) et des reliefs transversaux (8) Fig: I.-Its external part (6) or "back of the belt" is notched, that is to say that along this back (6) alternate transverse grooves (7) and transverse reliefs (8) Fig: I .

Brize à cette disposition, on peut monter la courroie (I) à la façon illustrée sur les figures 2 et 3. Dans ce cas elle circule sans fin entre deux poulies (9) et (IO) à gorge trapézoldale, cependant que son dos cranté (6) coopère avec une roue crantée (II) contre laquelle il circule. Brize to this arrangement, the belt (I) can be mounted as illustrated in Figures 2 and 3. In this case it circulates endlessly between two pulleys (9) and (IO) with trapezoidal groove, however its notched back (6) cooperates with a toothed wheel (II) against which it circulates.

Pour améliorer le contact avec la roue crantée (II), on SrOvoit, de part et d'autre de celle-ci, deux galets (I2) portés chacun par un étrier (I3) articulé sur un axe fixe (I4).To improve the contact with the toothed wheel (II), on SrOvoit, on either side of the latter, two rollers (I2) each carried by a stirrup (I3) articulated on a fixed axis (I4).

Un moyen de rappel élastique (I5), ressort ou analogue, relie les deux étriers.An elastic return means (I5), spring or the like, connects the two stirrups.

Dans le cas particulier de la figure 2, la poulie (9) est calée sur l'axe du villebrequin d'un moteur thermique (I6) dont l'alternateur (I7) est entraîné par la poulie (IO). In the particular case of Figure 2, the pulley (9) is wedged on the axis of the crankshaft of a heat engine (I6) whose alternator (I7) is driven by the pulley (IO).

Le support (I8) de l'alternateur porte par ailleurs l'axe (I4) des étriers tendeurs (I3) gràce auxquels les galets (I2) appuient sur la partie intérieure (2) de la courroie (I), comme schématisé par les flèches situées de part et d'autre de la roue crantée (II).The support (I8) of the alternator also carries the axis (I4) of the tensioning stirrups (I3) thanks to which the rollers (I2) press on the internal part (2) of the belt (I), as shown schematically by the arrows located on either side of the toothed wheel (II).

Cette dernière estraine le ou les rotors d'un compresseur de suralimentation (20); lequel peut entre de tous types connus; notamment: -Une turbine -Ou bien un compresseur volumétrique, et notamment un compresseur à deux rotors engrenant l'un dans l'autre. The latter drives the rotor (s) of a supercharging compressor (20); which can be of any known type; in particular: -A turbine -Or a positive displacement compressor, and in particular a compressor with two rotors meshing one in the other.

Le fonctionr.ement est le suivant: -Par sa partie intérieure trapézosdale (2), la courroie (I) entraine à la manière connue l'alternateur (I7) du moteur (I6).The function is as follows: -By its trapezoidal internal part (2), the belt (I) drives the alternator (I7) of the engine (I6) in the known manner.

-Par ailleurs, sa partie extérieure crantée (6) assure une liaison de transmission sans glissement avec la roue (II) du compresseur (20) qu'elle entraine. -In addition, its notched outer part (6) provides a non-slip transmission link with the wheel (II) of the compressor (20) which it drives.
