Description

DESCRIPTION DESCRIPTION
TITRE DE L’INVENTION : DISPOSITIF DE FREINAGE A TAMBOUR COMPORTANT PLUSIEURS AIMANTS TITLE OF THE INVENTION: DRUM BRAKING DEVICE COMPRISING SEVERAL MAGNETS
La présente invention revendique la priorité de la demande française 2106681 déposée le 23 juin 2021 , dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application 2106681 filed on June 23, 2021, the content of which (text, drawings and claims) is incorporated herein by reference.
La présente invention concerne un dispositif de freinage pour un véhicule qui comporte un frein à tambour adapté pour collecter des particules magnétiques de poussière de freinage émise lors du freinage du véhicule. La présente invention concerne plus particulièrement un tel dispositif de freinage pour un véhicule qui comporte un frein à tambour comportant une première partie destinée à être fixé sur un train roulant dudit véhicule et une seconde partie formant un support pour fixer une roue dudit train roulant, la première partie comportant un plateau métallique dont la paroi intérieure forme un support pour deux segments déplaçables, chaque segment étant munis d’une garniture de freinage, la seconde partie comportant un tambour dont la paroi intérieur latérale est adaptée pour former une surface d’appui aux garnitures de freinage lors d’une phase de freinage, la fiction des garnitures de freinage contre le tambour créant des particules magnétiques de poussière de freinage, le frein à tambour comportant des aimants adaptés pour retenir au moins une partie desdites particules magnétiques de poussière de freinage. The present invention relates to a braking device for a vehicle which comprises a drum brake adapted to collect magnetic particles of braking dust emitted during braking of the vehicle. The present invention relates more particularly to such a braking device for a vehicle which comprises a drum brake comprising a first part intended to be fixed to a running gear of said vehicle and a second part forming a support for fixing a wheel of said running gear, the first part comprising a metal plate, the inner wall of which forms a support for two movable segments, each segment being provided with a brake lining, the second part comprising a drum, the inner side wall of which is adapted to form a bearing surface for the brake linings during a braking phase, the fiction of the brake linings against the drum creating magnetic particles of braking dust, the drum brake comprising magnets adapted to retain at least a part of said magnetic particles of braking dust .
Est divulgué dans le document brevet FR-A1 -3101385 une installation où est positionné dans la partie centrale du tambour un réceptacle comportant des aimants sur lesquelles des particules magnétiques de poussière de freinage viennent se coller. Is disclosed in the patent document FR-A1 -3101385 an installation where is positioned in the central part of the drum a receptacle comprising magnets on which magnetic particles of braking dust come to stick.
Une telle solution est certes passive, mais elle complexifie et alourdit le dispositif de freinage et en outre, elle ne permet de collecter que les particules qui sont parvenues dans le réceptacle, lesquelles sont peu nombreuses du fait de la distance séparant leur lieu de production de l’aimant et des obstacles à franchir sur le trajet (étages, orifices étroits). Such a solution is certainly passive, but it complicates and weighs down the braking device and moreover, it only makes it possible to collect the particles which have reached the receptacle, which are few in number due to the distance separating their place of production from the magnet and the obstacles to be overcome on the way (floors, narrow openings).
Le dispositif selon l’invention permet de remédier à cet inconvénient. Il comporte en effet, selon l’invention, un dispositif de freinage pour un véhicule qui comporte un frein à tambour comportant une première partie destinée à être fixé sur un train roulant dudit véhicule et une seconde partie formant un support pour fixer une roue dudit train roulant, la première partie comportant un plateau métallique dont la paroi intérieure forme un support pour deux segments déplaçables, chaque segment étant munis d’une garniture de freinage, la seconde partie comportant un tambour dont la paroi intérieur latérale est adaptée pour former une surface d’appui aux garnitures de freinage lors d’une phase de freinage, la fiction des garnitures de freinage contre le tambour créant des particules magnétiques de poussière de freinage, le frein à tambour comportant des aimants adaptés pour retenir au moins une partie desdites particules magnétiques de poussière de freinage, tel que les aimants sont positionnés le long de son bord périphérique du plateau. The device according to the invention overcomes this drawback. It comprises in fact, according to the invention, a braking device for a vehicle which comprises a drum brake comprising a first part intended to be fixed on a running gear of said vehicle and a second part forming a support for fixing a wheel of said train roller, the first part comprising a metal plate, the inner wall of which forms a support for two movable segments, each segment being provided with a brake lining, the second part comprising a drum, the lateral inner wall of which is adapted to form a surface of support for the brake linings during a braking phase, the fiction of the brake linings against the drum creating magnetic particles of braking dust, the drum brake comprising magnets adapted to retain at least a part of said magnetic particles of brake dust, such that magnets are positioned along its peripheral edge of the platter.
Selon une première caractéristique de l’invention, en périphérie du frein à tambour, entre la première partie et la seconde partie, est formée une ouverture périphérique, les aimants étant positionnés en bordure de ladite ouverture périphérique. According to a first characteristic of the invention, on the periphery of the drum brake, between the first part and the second part, is formed a peripheral opening, the magnets being positioned at the edge of said peripheral opening.
Selon une deuxième caractéristique de l’invention, les aimants sont positionnés dans des logements positionnés à l’extérieure du frein à tambour. According to a second feature of the invention, the magnets are positioned in housings positioned outside the drum brake.
Selon une troisième caractéristique de l’invention, des ouvertures sont formées le long de la bordure du plateau en correspondance desdits logements pour le passage des particules magnétiques de poussière de freinage vers les aimants, préférentiellement, les logements sont séparés deux à deux d’un secteur angulaire égal à 60 degrés, mais un secteur angulaire plus petit peu aussi être envisagé, cela augmente le prix de production du dispositif de freinage et son poids, mais cela augmente la quantité de particules magnétiques de poussière de freinage qui sont récupérés dans les logements. Préférentiellement, les logements sont amovibles permettant de les retirer pour enlever les particules magnétiques de poussière de freinage sans démonter le frein à tambour. According to a third characteristic of the invention, openings are formed along the edge of the plate in correspondence of said housings for the passage of the magnetic particles of braking dust towards the magnets, preferably, the housings are separated two by two by a angular sector equal to 60 degrees, but a smaller angular sector can also be envisaged, this increases the production cost of the braking device and its weight, but this increases the quantity of magnetic particles of braking dust which are collected in the housings . Preferably, the housings are removable, allowing them to be removed in order to remove the magnetic particles of braking dust without dismantling the drum brake.
De tels logements sont préférentiellement en métal. Such housings are preferably made of metal.
La présente invention concerne aussi un train roulant de véhicule automobile comportant un dispositif de freinage qui comporte au moins une des caractéristiques précédentes. Elle concerne aussi un véhicule qui comporte au moins un tel train roulant, un tel train roulant constituant généralement un train arrière du véhicule. Les dessins annexés illustrent l’invention : The present invention also relates to a motor vehicle running gear comprising a braking device which comprises at least one of the preceding characteristics.
