Description

La présente invention concerne le domaine des machines tournantes notamment pour véhicules automobiles et en particulier les machines tournantes à collecteur tels que les démarreurs, alternateurs et alterno-démarreurs.The present invention relates to the field of rotating machinery, in particular for motor vehicles, and in particular rotating commutator machines such as starters, alternators and alternator-starters.

Il est connu dans l'état de la technique d'utiliser un ou plusieurs balais de contact électrique associés au stator et destinés à venir en contact avec un collecteur associé au rotor pour alimenter le bobinage du rotor via les pistes du collecteur. Pour permettre le contact entre le balai de contact électrique et le collecteur, des ressorts sont utilisés pour contraindre les balais contre le collecteur.It is known in the state of the art to use one or more electric contact brushes associated with the stator and intended to come into contact with a collector associated with the rotor for supplying the rotor winding via the collector tracks. To allow contact between the electrical contact mop and the collector, springs are used to constrain the brushes against the collector.

Le document US 6 232 695 décrit des balais pour moteur à courant continu commuté. Ce document décrit le préambule de la revendication 1.The document US 6,232,695 describes brushes for DC motor switched. This document describes the preamble of claim 1.

Par ailleurs, lors du fonctionnement de la machine tournante à collecteur, le frottement entre le balai de contact électrique et le collecteur entraîne une usure du balai de contact dont la hauteur de vie, c'est-à-dire la dimension du balai perpendiculaire à la face active qui est en contact avec le collecteur, diminue de sorte que la force exercée par le ressort sur le balai de contact électrique pour le maintenir contre le collecteur diminue.Moreover, during the operation of the rotating machine with collector, the friction between the electrical contact mop and the collector causes wear of the contact broom whose life height, that is to say the dimension of the broom perpendicular to the active face which is in contact with the collector decreases so that the force exerted by the spring on the electric contact mop to hold it against the collector decreases.

Cette diminution de la force et donc de la pression entre le balai de contact électrique et le collecteur entraîne des pertes au niveau de la machine tournante.This reduction in the force and therefore the pressure between the electric contact broom and the collector causes losses in the rotating machine.

Il convient donc de trouver une solution permettant d'obtenir une pression sensiblement constante entre le balai de contact électrique et le collecteur.It is therefore necessary to find a solution to obtain a substantially constant pressure between the electric contact broom and the collector.

A cet effet, la présente invention a pour objet un balai de machine tournante à collecteur d'un véhicule automobile selon la revendication 1. Ce balai comprend notamment :

  • une première partie, dite partie d'usure, comprenant une face active destinée à être au moins partiellement en contact avec le collecteur pour alimenter le bobinage d'un rotor, la première partie comprenant une hauteur de vie qui est une dimension perpendiculaire à la face active qui est en contact avec le collecteur,
dans lequel la section de la première partie du balai, dans un plan parallèle à la face active, dite section efficace, diminue, au moins par paliers, selon la hauteur de vie du balai en s'éloignant de la face active.For this purpose, the subject of the present invention is a rotating machine broom with a collector of a motor vehicle according to claim 1. This broom comprises in particular:
  • a first part, called the wear part, comprising an active face intended to be at least partially in contact with the collector for feeding the winding of a rotor, the first part comprising a height of life which is a dimension perpendicular to the face active which is in contact with the collector,
wherein the section of the first portion of the blade, in a plane parallel to the active face, said effective section, decreases, at least stepwise, according to the life of the blade away from the active face.

On obtient donc une surface active ou surface de contact qui diminue pendant au moins une partie de la durée de vie du balai. La diminution, au moins par paliers, de la section efficace sur la partie d'usure du balai permet de réduire la surface de la face active au cours du temps lors de l'usure du balai de sorte que la réduction de la surface active permet de compenser la diminution de la force exercée par un élément élastique tel qu'un ressort et ainsi d'obtenir une pression sensiblement constante au cours du temps entre le balai et le collecteur lors de l'usure du balai.An active surface or contact surface is thus obtained which decreases during at least part of the life of the blade. The reduction, at least in steps, of the effective section on the wear portion of the blade reduces the surface of the active face over time during the wear of the blade so that the reduction of the active surface allows to compensate for the decrease of the force exerted by an elastic element such as a spring and thus to obtain a substantially constant pressure over time between the blade and the commutator during the wear of the blade.

La présente invention peut également être définie par un balai de contact comprenant :

  • une face active comprenant une surface de contact destinée à venir en contact avec le collecteur,
  • une face avant comprenant une hauteur de vie et des largeurs mesurées perpendiculairement à la hauteur de vie et en ce que la face avant comprend une largeur plus petite qu'une largeur de la face avant mesurée plus proche de la face active,
ou par,
un balai de contact de machines tournantes à collecteur d'un véhicule automobile comprenant :
  • une première partie, dite partie d'usure, comprenant une face active destinée à être au moins partiellement en contact avec le collecteur pour alimenter le bobinage d'un rotor,
dans lequel le profil du balai selon un plan sensiblement normal à la face active, dit profil d'usure, présente une forme convergente en s'éloignant de la face active.The present invention can also be defined by a contact broom comprising:
  • an active face comprising a contact surface intended to come into contact with the collector,
  • a front face comprising a height of life and widths measured perpendicularly to the height of life and in that the front face comprises a width smaller than a width of the measured front face closer to the active face,
or by,
a contact broom of rotating machines with collector of a motor vehicle comprising:
  • a first part, called the wear part, comprising an active face intended to be at least partially in contact with the collector for supplying the winding of a rotor,
wherein the profile of the brush in a plane substantially normal to the active face, said wear profile, has a convergent shape away from the active face.

Selon un autre aspect de la présente invention, le balai comprend également une deuxième partie, dite partie de maintien, opposée à la face active de la première partie et configurée pour permettre le maintien du balai.According to another aspect of the present invention, the blade also comprises a second portion, said holding portion, opposite to the active face of the first portion and configured to allow the maintenance of the blade.

La partie de maintien permet de conserver une section fixe à l'arrière du balai et ainsi permettre la coopération avec un porte-balai standard.The holding part makes it possible to keep a fixed section at the rear of the blade and thus allow cooperation with a standard brush holder.

Selon un aspect additionnel de la présente invention, la diminution est continue sur la hauteur de vie du balai.According to an additional aspect of the present invention, the decrease is continuous over the life of the blade.

Une diminution continue de la section efficace sur la hauteur de vie du balai permet de compenser la diminution de la force de l'élément élastique durant toute la durée de vie du balai.Continuous reduction of the cross-section over the life of the blade makes it possible to compensate for the decrease in the strength of the elastic element during the entire life of the blade.

Selon un aspect additionnel de la présente invention, la diminution est linéaire sur la hauteur de vie du balai.According to an additional aspect of the present invention, the decrease is linear over the life of the blade.

Une diminution linéaire permet de compenser au mieux la diminution linéaire de la force appliquée par l'élément élastique.A linear decrease makes it possible to better compensate for the linear decrease in the force applied by the elastic element.

Selon un aspect supplémentaire de la présente invention, le rapport entre la section efficace du balai au niveau de l'extrémité de la première partie opposée à la face active et la section efficace du balai au niveau de la face active est égale au rapport de la force de l'élément élastique en début sur le balai sur la force du ressort sur le balai à l'état d'usure du balai au niveau de l'extrémité de la première partie de manière à diminuer une variation de la pression du balai sur le collecteur lors de sa durée de vie.According to a further aspect of the present invention, the ratio between the effective section of the blade at the end of the first portion opposite the active face and the effective section of the blade at the active face is equal to the ratio of the the force of the elastic element at the beginning of the blade on the force of the spring on the blade in the state of wear of the blade at the end of the first part so as to reduce a variation of the pressure of the blade on the collector during its lifetime.

Selon la présente invention, le balai comprend une face avant adjacente à la face active au niveau d'un bord d'attaque et une face arrière adjacente à la face active au niveau d'un bord de fuite, la face avant et la face arrière étant reliées par une première et une deuxième faces latérales, dans lequel au moins deux des faces parmi :

  • la face avant,
  • la face arrière,
  • la première face latérale et,
  • la deuxième face latérale
s'étendent perpendiculairement à la face active, les, au moins deux, faces s'étendant perpendiculairement à la face active comprennent la face avant et la face arrière.According to the present invention, the blade comprises a front face adjacent to the active face at a leading edge and a rear face adjacent to the active face at a trailing edge, the front face and the rear face. being connected by first and second side faces, wherein at least two of the faces of:
  • the front,
  • the back side,
  • the first side face and,
  • the second side face
extend perpendicularly to the active face, the at least two faces extending perpendicularly to the active face comprise the front face and the rear face.

L'utilisation d'un balai comprenant une face avant et une face arrière s'étendant perpendiculairement à la face active permet de maintenir la largeur, entre le bord d'attaque et le bord de fuite, de la face active constante pendant la durée de vie du balai et ainsi assurer le fait que le balai est en contact simultanément avec plusieurs pistes du collecteur tout au long de sa durée de vie.The use of a wiper comprising a front face and a rear face extending perpendicularly to the active face makes it possible to maintain the width, between the leading edge and the trailing edge, of the active face constant for the duration of life of the broom and so ensure the the broom is in contact simultaneously with several tracks of the collector throughout its life.

La présente invention concerne également une machine tournante à collecteur d'un véhicule automobile comprenant au moins un balai selon l'une quelconque des revendications précédentes.The present invention also relates to a rotating machine with a collector of a motor vehicle comprising at least one blade according to any one of the preceding claims.

De simples caractéristiques de différents modes de réalisation peuvent également être combinées pour fournir d'autres réalisations.The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.

La figure 1 représente un schéma d'un ensemble comprenant un balai de contact 1 et un collecteur 7 d'une machine tournante, notamment un démarreur, un alternateur ou un alterno-démarreur, d'un véhicule automobile. Le balai de contact 1 est maintenu par un porte-balai 2 qui entoure partiellement le balai de contact 1. Le porte-balai 2 comprend également un moyen élastique 4, par exemple un ressort métallique, pour contraindre le balai de contact 1 contre le collecteur 7 pour permettre d'alimenter le bobinage d'un rotor de la machine tournante. Le contact entre le balai 1 et le collecteur 7 est réalisé au niveau d'une face dite face active 3 du balai 1. Ainsi, lors de la rotation du collecteur 7 dont le sens de rotation est représenté par la flèche 12, la face active 3 du balai 1 vient successivement en contact avec les différentes pistes 5 du collecteur 7. Le balai 1 est à chaque instant en contact avec au moins deux pistes 5 du collecteur 7.The figure 1 represents a diagram of an assembly comprising a contact broom 1 and a commutator 7 of a rotating machine, in particular a starter, an alternator or an alternator-starter, of a motor vehicle. The contact broom 1 is held by a brush holder 2 which partially surrounds the contact broom 1. The brush holder 2 also comprises an elastic means 4, for example a metal spring, to force the contact broom 1 against the collector 7 to allow powering the winding of a rotor of the rotating machine. The contact between the blade 1 and the manifold 7 is formed at a so-called active face 3 of the blade 1. Thus, during the rotation of the manifold 7 whose direction of rotation is represented by the arrow 12, the active face 3 of the blade 1 comes successively in contact with the different tracks 5 of the collector 7. The brush 1 is in each moment in contact with at least two tracks 5 of the collector 7.

La face active 3 comprend un premier bord dit bord d'attaque 9 qui est le bord par lequel la face active 3 rentre en contact avec une piste 5 lors de la rotation du collecteur 7 et un deuxième bord dit bord de fuite 11 qui est le bord par lequel la face active 3 perd le contact avec une piste 5 du collecteur 7 lors de la rotation du collecteur 7.The active face 3 comprises a first edge called leading edge 9 which is the edge by which the active face 3 comes into contact with a track 5 during the rotation of the collector 7 and a second edge said trailing edge 11 which is the edge by which the active face 3 loses contact with a track 5 of the collector 7 during the rotation of the collector 7.

Dans le cas d'un collecteur 7 cylindrique comme représenté sur les figures 1 et 2a, la face active 3 n'est pas plane mais incurvée (ou s'incurve lors de l'usure du balai 1) du fait de la forme cylindrique du collecteur 7. Cependant dans la suite de la description, on considérera que la face active 5 forme un plan comprenant le bord d'attaque 9 et le bord de fuite 11.In the case of a cylindrical collector 7 as shown in FIGS. figures 1 and 2a , the active face 3 is not flat but curved (or curves when the brush 1 is worn) because of the cylindrical shape of the collector 7. However, in the remainder of the description, it will be considered that the active face 5 forms a plane comprising the leading edge 9 and the trailing edge 11.

Il est également à noter que la présente invention s'étend également aux collecteurs 7 plats comme représenté sur la figure 2b pour lesquels le balai 1 vient en contact avec une surface plane du collecteur 7 comprenant les pistes 5. Dans ce cas, la surface active 3 reste plane lors de l'usure du balai 1.It should also be noted that the present invention also extends to flat collectors as shown in FIG. figure 2b for which the blade 1 comes into contact with a flat surface of the manifold 7 comprising the tracks 5. In this case, the active surface 3 remains flat during the wear of the blade 1.

Le sens de rotation du collecteur 7 est repéré par les flèches 12 sur les figures 2a et 2b.The direction of rotation of the manifold 7 is indicated by the arrows 12 on the Figures 2a and 2b .

La figure 3 représente une vue en perspective d'un balai de contact 1 selon un premier mode de réalisation de la présente invention. Le balai 1 a une forme générale parallélépipédique avec une face avant 13 adjacente à la face active 3 au niveau du bord d'attaque 9 et une face arrière 15 adjacente à la face active 3 au niveau du bord de fuite 11. La balai 1 comprend également une première 17 et une deuxième 19 faces latérales adjacentes à la face active 3 et qui relient la face avant 13 et la face arrière 15. La face arrière 15, la première 17 et la deuxième 19 faces latérales s'étendent perpendiculairement à la face active 3.The figure 3 is a perspective view of a contact broom 1 according to a first embodiment of the present invention. The blade 1 has a parallelepipedal general shape with a front face 13 adjacent to the active face 3 at the leading edge 9 and a rear face 15 adjacent to the active face 3 at the trailing edge 11. The blade 1 comprises also a first 17 and a second 19 side faces adjacent to the active face 3 and which connect the front face 13 and the rear face 15. The rear face 15, the first 17 and the second 19 side faces extend perpendicular to the face active 3.

Le balai de contact 1 peut être divisé en deux parties, une première partie dite partie d'usure 21 comprenant la face active 3. La partie d'usure 21 étant destinée à devenir la face active 3 lors de la durée de vie du balai 1. En effet, le frottement du balai 1 sur le collecteur 7 provoque l'usure du balai 1 dont les particules se déposent sur le collecteur 7 pour former une patine à la surface des pistes 5 du collecteur 7. Ainsi, la hauteur du balai dans une direction perpendiculaire à la face active 3 appelée hauteur de vie H tend à diminuer au cours du temps lors de l'utilisation de la machine tournante.The contact broom 1 can be divided into two parts, a first part called wear portion 21 comprising the active face 3. The wear part 21 being intended to become the active face 3 during the life of the blade 1 Indeed, the friction of the blade 1 on the manifold 7 causes the wear of the blade 1 whose particles are deposited on the manifold 7 to form a patina on the surface of the tracks 5 of the manifold 7. Thus, the height of the blade in a direction perpendicular to the active face 3 called height of life H tends to decrease over time when using the rotating machine.

Le balai de contact 1 comprend également une deuxième partie dite partie de maintien 23 opposée à la face active 3 et destinée au maintien du balai 1 par un porte-balai 2. Les porte-balais 2 étant généralement standard, les dimensions (longueur L et largeur 1) de la partie de maintien 23 sont imposées par le standard. La partie de maintien 23 comprend un fil électrique 24, appelé « shunt » en anglais, destiné à fournir un courant électrique au balai 1 et peut également comprendre un ou plusieurs renfoncements 26 ménagés sur la face opposée à la face active 3 dans lesquels viennent se loger une extrémité des éléments élastiques 4, par exemple des ressorts métalliques, qui assurent la mise en contact entre la balai 1 et le collecteur 7.The contact broom 1 also comprises a second part called holding portion 23 opposite to the active face 3 and intended to hold the blade 1 by a brush holder 2. The brush holders 2 are generally standard, the dimensions (length L and width 1) of the holding portion 23 are imposed by the standard. The holding portion 23 comprises an electric wire 24, called a "shunt" in English, intended to provide an electric current to the blade 1 and may also include one or more recesses 26 formed on the face opposite the active face 3 in which come housing one end of the elastic elements 4, for example metal springs, which ensure the contact between the blade 1 and the collector 7.

La séparation entre la partie d'usure 21 et la partie de maintien 23 est repérée par une ligne en pointillés sur la figure 3. Cette séparation se situe généralement au niveau de la limite du fil électrique 24.The separation between the wear portion 21 and the holding portion 23 is indicated by a dashed line on the figure 3 . This separation is generally at the level of the limit of the electric wire 24.

On définit la section de la partie d'usure 21 du balai 1 dans un plan parallèle à la face active 3, c'est à dire selon un plan normal à la hauteur de vie H, comme étant la section efficace et le balai de contact 1 est configuré pour que sa section efficace diminue en s'éloignant de la face active 3, au niveau de la partie d'usure 21. Ainsi, la surface de la face active 3 diminue pendant la durée de vie du balai ce qui permet d'obtenir une pression sensiblement constante entre le balai de contact 3 et le collecteur 7 au cours de la durée de vie du balai 1. En effet, le moyen élastique 4, comme par exemple le ressort métallique, applique une force qui tend à décroître lors de l'usure du balai 1 du fait de la diminution de la hauteur de vie H. La diminution de la section efficace au cours de l'usure du balai 1 permet de contrecarrer ou compenser la diminution de la force appliquée par l'élément élastique 4 et d'obtenir une pression sensiblement constante entre le balai 1 et le collecteur 7.The section of the wear portion 21 of the blade 1 is defined in a plane parallel to the active face 3, ie in a plane normal to the height of life H, as being the effective section and the contact broom. 1 is configured so that its effective cross section decreases away from the active face 3, at the wear portion 21. Thus, the surface of the active face 3 decreases during the life of the brush which allows to get a pressure substantially constant between the contact broom 3 and the collector 7 during the life of the brush 1. Indeed, the resilient means 4, such as the metal spring, applies a force that tends to decrease during wear of the blade 1 because of the decrease in the height of life H. The reduction of the effective section during the wear of the blade 1 can counteract or compensate for the decrease in the force applied by the elastic element 4 and obtain a substantially constant pressure between the broom 1 and the collector 7.

Cette diminution de la section efficace du balai 1 selon la hauteur de vie H en s'éloignant de la face active 3 est par exemple obtenue par une face avant 13 formant un angle aigu avec la face active 3 comme représenté sur la figure 3. L'angle aigu est par exemple déterminé de manière à ce que le rapport de :

  • la section efficace du balai au niveau de l'extrémité de la première partie opposée à la face active sur la section efficace du balai au niveau de la face active,
  • est en fonction de la raideur de l'élément élastique par rapport à l'état d'usure du balai de manière à diminuer la variation de la pression du balai sur le collecteur.
Ce rapport est avantageusement égal au rapport de la force de l'élément élastique en début sur le balai sur la force du ressort sur le balai à l'état d'usure du balai au niveau de l'extrémité de la première partie 21. Cela permet d'avoir une pression constante au niveau de la face active du balai sur le collecteur.
Par exemple, si la pression du ressort sur un balai neuf est de 26N, puis lorsque le balai est usé jusqu' au niveau de l'extrémité de la première partie (par exemple après une course de 15mm) la pression du ressort sur le balai n'est plus que de 21N, le ressort appuie donc seulement 80% des 26N du départ, soit appuie sur le balai 20% moins fort à ce niveau d'extrémité qu'en début de vie, alors le rapport de la section efficace du balai au niveau de l'extrémité de la première partie opposée à la face active et la section efficace du balai au niveau de la face active est de 80% entre la section efficace et la section du balai en fin de vie. Un tel rapport permet d'assurer une surface de contact suffisante entre le balai 1 et le collecteur 7 pour permettre le bon fonctionnement de la machine tournante quelle que soit l'usure du balai 1.This reduction of the effective section of the blade 1 according to the height of life H away from the active face 3 is for example obtained by a front face 13 forming an acute angle with the active face 3 as shown in FIG. figure 3 . The acute angle is for example determined so that the ratio of:
  • the effective section of the blade at the end of the first portion opposite the active face on the effective section of the blade at the active face,
  • is a function of the stiffness of the elastic member with respect to the state of wear of the brush so as to reduce the variation of the pressure of the brush on the manifold.
This ratio is advantageously equal to the ratio of the force of the elastic element at the beginning on the blade to the force of the spring on the blade in the state of wear of the blade at the end of the first part 21. This allows constant pressure at the active side of the broom on the collector.
For example, if the spring pressure on a new broom is 26N, then when the broom is worn up to the end of the first part (eg after a stroke of 15mm) the spring pressure on the broom is now only 21N, so the spring supports only 80% of the 26N at the start, or the 20% lower broom presses at this end level than at the beginning of life, then the ratio of the cross-section of the broom at the end of the first part opposite the active face and the effective section of the broom at the active side is 80% between the effective section and the section of the broom at the end of life. Such ratio ensures a sufficient contact area between the brush 1 and the manifold 7 to allow the smooth operation of the rotating machine regardless of the wear of the blade 1.

La figure 4 représente le profil du balai de contact 1 de la figure 3 selon un plan normal aux bords d'attaque 9 et de fuite 11 correspondant à une vue dans la direction de la deuxième face latérale 19. Dans le cas de la figure 3, la section du balai 1 est constante entre la première 17 et la deuxième 19 face latérale, cependant, la présente invention ne se limite pas à une section constante entre la première 17 et la deuxième 19 face latérale.The figure 4 represents the profile of the contact broom 1 of the figure 3 in a plane normal to the leading edges 9 and trailing 11 corresponding to a view in the direction of the second side face 19. In the case of the figure 3 , the section of the blade 1 is constant between the first 17 and the second 19 side face, however, the present invention is not limited to not at a constant section between the first 17 and second 19 side face.

L'inclinaison de la face avant 15 par rapport à la face active 3 permet d'obtenir une réduction de la section normale à la hauteur de vie H.The inclination of the front face 15 with respect to the active face 3 makes it possible to obtain a reduction of the section normal to the height of life H.

Un angle aigu peut également être ménagé entre la face active 3 et la face arrière 15, la face avant 13 étant alors sensiblement normale à la face active 3.An acute angle can also be provided between the active face 3 and the rear face 15, the front face 13 then being substantially normal to the active face 3.

Selon un autre mode de réalisation représenté sur la figure 5, la face avant 13 et la face arrière 15 présentent un angle aigu par rapport à la face active 3.According to another embodiment shown on the figure 5 the front face 13 and the rear face 15 have an acute angle with respect to the active face 3.

Par ailleurs, la réduction de la section efficace au cours de l'usure peut également être obtenue par un balai 1 comprenant un angle aigu entre la face active 3 et la première face latérale 17 ou entre la face active 3 et la deuxième face latérale 19 comme représenté sur la figure 6. Alternativement, la première 17 et la deuxième 19 faces latérales présentent un angle aigu par rapport à la face active 3.Moreover, the reduction of the effective section during wear can also be obtained by a blade 1 comprising an acute angle between the active face 3 and the first lateral face 17 or between the active face 3 and the second lateral face 19 as represented on the figure 6 . Alternatively, the first 17 and second 19 side faces have an acute angle with respect to the active face 3.

Il est également possible de combiner les différents modes de réalisation précédents avec plusieurs faces présentant un angle aigu par rapport à la face active, par exemple la face avant 13 et la première face latérale 17.It is also possible to combine the various previous embodiments with several faces having an acute angle with respect to the active face, for example the front face 13 and the first side face 17.

Par ailleurs, la réduction de la section efficace du balai 1 au cours de son usure peut également être réalisée de façon non linéaire voire non continue. En effet, au lieu de ménager un face présentant un angle aigu par rapport à la face active 3, la face peut présenter une surface convexe ou concave ou toute autre forme présentant une forme divergente vers la face active 3 comme par exemple un profil en escalier comme représenté sur la figure 7. La réduction de la section efficace peut également être obtenue par un ou plusieurs trous ménagés dans le balai 1 et présentant un forme convergente vers la face active 3 du balai de contact 1.Furthermore, the reduction of the effective section of the blade 1 during its wear can also be carried out non-linearly or non-continuously. Indeed, instead of providing a face having an acute angle with respect to the active face 3, the face may have a convex or concave surface or any other shape having a divergent shape towards the active face 3 such as a staircase profile as represented on the figure 7 . The reduction of the cross section can also be obtained by one or more holes formed in the blade 1 and having a shape that converges towards the active face 3 of the contact broom 1.

Ainsi, l'utilisation d'un balai de contact 1 présentant une section efficace qui diminue en s'éloignant de la face active 3 permet de réduire la surface de la face active3, c'est-à-dire la surface en contact avec le collecteur 7 et ainsi obtenir une pression du balai 1 sur le collecteur 7 sensiblement constante au cours du temps durant la durée de vie du balai 1 malgré la diminution de la force exercée par l'élément élastique 4, comme par exemple un ressort métallique, sur le balai 1.Thus, the use of a contact broom 1 having an effective section which decreases away from the active face 3 reduces the surface of the active face 3, that is to say the surface in contact with the manifold 7 and thus obtain a pressure of the brush 1 on the collector 7 substantially constant over time during the life of the blade 1 despite the decrease in the force exerted by the elastic element 4, such as a metal spring, on the broom 1.
