Description
« Guide de glissement de patin de garniture pour réduction du freinage résiduel » L'invention se rapporte à un guide de coulissement de patin de frein à disque pour véhicule, notamment routier, agencé pour générer un effort plus important quand le patin coulisse dans le sens du serrage que dans le sens du desserrage.The invention relates to a sliding guide for a disk brake shoe for a vehicle, in particular a road vehicle, designed to generate a greater force when the shoe slides in the direction of travel. tightening only in the direction of loosening.
Etat de la techniqueState of the art
Les freins à disque de véhicule comprennent généralement un organe fixe en rotation qui coiffe le disque ou rotor sur une portion de sa périphérie. A l'intérieur des branches de cet étrier est disposée au moins une paire de patins ou garnitures de freinage disposées de part et d'autre du disque et se faisant face, au niveau de deux pistes de freinage annulaires formées sur les deux faces du disque. Pour réaliser le freinage, un ou plusieurs pistons se déplacent vers le disque pour appliquer un effort de serrage qui rapproche l’une de l’autre les garnitures d'une même paire, ce qui les amène à frotter sur les pistes de frottement du disque et ainsi à en ralentir la rotation. Sur leur périphérie, les garnitures sont dotées chacune de deux oreilles disposées en deux emplacements sensiblement opposés, chaque oreille coulissante dans une cavité ménagée l'organe fixe.The vehicle disc brakes generally comprise a fixed rotating member which covers the disc or rotor on a portion of its periphery. Inside the branches of this stirrup is disposed at least one pair of brake shoes or pads disposed on either side of the disc and facing each other, at two annular braking tracks formed on both sides of the disc. . To carry out the braking, one or more pistons move towards the disk to apply a tightening force which brings the packings of the same pair closer to one another, which causes them to rub on the friction tracks of the disc. and thus to slow down the rotation. On their periphery, the fittings each have two lugs arranged in two substantially opposite positions, each ear sliding in a cavity formed the fixed member.
Dans les freins à disque aussi bien « à étrier fixe » que « à étrier coulissant » avec chape, et telles que décrit dans les documents respectivement US20130068573 et FR3005127, il est connu d'interposer des guides de glissement à l'intérieur des cavités afin de faciliter la translation des garnitures de freinage au sein de la cavité de l'organe fixe, en minimisant les frottement. Lors du freinage, l’appui des garnitures sur l'organe fixe est alors transmis par les guides de glissement qui subissent une compression dans le sens de leur épaisseur. A l'issue d'un freinage, il peut se subsister un freinage "résiduel", c'est à dire engendré par un frottement qui subsiste entre le disque et la garniture du patin si celle-ci est encore en contact avec le disque. Ce freinage résiduel est source de divers inconvénients, par exemple surconsommation, bruits, émissions de poussières.In disc brakes as well "with fixed caliper" and "sliding caliper" with clevis, and as described in documents respectively US20130068573 and FR3005127, it is known to interpose sliding guides inside the cavities so to facilitate the translation of the brake linings within the cavity of the fixed member, minimizing friction. During braking, the support of the linings on the fixed member is then transmitted by the sliding guides which undergo compression in the direction of their thickness. At the end of braking, there may be a "residual" braking, that is generated by a friction which remains between the disc and the lining of the pad if it is still in contact with the disc. This residual braking is a source of various disadvantages, for example overconsumption, noise, dust emissions.
Pour réduire le couple de freinage résiduel, la démarche actuelle est de réduire les efforts nécessaires à faire coulisser le patin. Donc l'énergie nécessaire pour écarter le patin du disque, transmise par le disque au patin, est réduite : le couple résiduel est réduit. Cependant, on note qu'un faible effort de coulissement permet aussi au patin d'être plus libre de ses mouvements, il peut alors revenir en contact avec le disque à cause des conditions de route ou de conduite (accélération latérale, vibration...), ou par restitution, générant du couple résiduel.To reduce the residual braking torque, the current approach is to reduce the effort required to slide the pad. So the energy required to move the disc pad, transmitted by the disk to the pad, is reduced: the residual torque is reduced. However, it is noted that a low sliding force also allows the pad to be more free of its movements, it can then come into contact with the disc because of road conditions or driving (lateral acceleration, vibration ... ), or by restitution, generating residual torque.
Un but de l'invention est de pallier tout ou partie des inconvénients de l'art antérieur, et en particulier de diminuer le freinage résiduel en durée et/ou en intensité, tout en maintenant ou amélioration la simplicité et la fiabilité de fabrication et de fonctionnement.An object of the invention is to overcome all or part of the disadvantages of the prior art, and in particular to reduce the residual braking time and / or intensity, while maintaining or improve the simplicity and reliability of manufacture and operation.
Exposé de l'invention L'invention propose un guide de coulissement de patin ("slider" en terminologie anglaise) qui permet et facilite le retour du patin par un effort de coulissement au plus faible, de façon égale ou similaire aux performances actuelles, mais est agencé pour générer un effort plus important quand le patin coulisse dans l'autre sens c'est à dire dans le sens du serrage.DESCRIPTION OF THE INVENTION The invention proposes a sliding slider guide which allows and facilitates the return of the slider by a sliding force at the lowest, in a manner equal to or similar to current performance, but is arranged to generate a greater force when the pad slides in the other direction that is to say in the direction of tightening.
Ce guide empêche ainsi le patin de pouvoir revenir vers le disque et donc de générer des nuisances, par exemple couple résiduel de freinage, bruit, ou usure prématurée.This guide thus prevents the pad from being able to return to the disk and thus generate nuisances, for example residual braking torque, noise, or premature wear.
Ce comportement peut être généré par différents moyens : - ressort radial avec anti-retour (voir FIGURE la à FIGURE le), un segment vient se planter et se comprimer quand le patin est avancé, ce qui augmente les efforts de coulissement dans ce sens et crée un restitution vers l'extérieur (en plus) - réalisation du guide de coulissement en une matière portant à sa surface des reliefs non symétriques et anti-retour, par exemple de type écailles de poisson, ou autres textures qui présente un faible coefficient de friction dans un sens, et élevé dans l'autre sens. - réalisation du guide de coulissement en une matière avec des reliefs, progressifs dans la direction du recul patin, plus agressifs dans le sens d'avancée du patin (FIGURE 2) - frange d'un coté en inox fournissant faible coefficient de frottement, et caoutchouc de l'autre côté, positionné sur la partie de reprise d'effort du patin.This behavior can be generated by various means: - radial spring with anti-return (FIGURE FIGURE 1 FIGURE 1), a segment is planted and compress when the pad is advanced, which increases the sliding forces in this direction and creates a return to the outside (in addition) - realization of the sliding guide in a material carrying on its surface non-symmetrical reliefs and non-return, for example fish scales, or other textures that has a low coefficient of friction in one direction, and elevated in the other direction. - Realization of the sliding guide in a material with reliefs, progressive in the direction of the retreating pad, more aggressive in the direction of advance of the pad (FIGURE 2) - a fringe on one side stainless steel providing low coefficient of friction, and rubber on the other side, positioned on the recovery part of the shoe.
Dans le cas d'un étrier coulissant, un tel patin est de préférence utilisé du côté du piston, mais peut aussi être utilisé du côté des doigts d'étrier.In the case of a sliding caliper, such a pad is preferably used on the piston side, but may also be used on the caliper fingers side.
