Description

La présente invention concerne un système d'antiblocage de roue pourThe present invention relates to an anti-lock wheel system for

véhicule à deux roues de type par exemple scooter.  two-wheeled vehicle type for example scooter.

Il existe déjà dans l'état de la technique, des systèmes de ce type qui comportent une cible associée en rotation à la roue du véhicule et un capteur correspondant adapté pour délivrer une information de vitesse de rotation de la roue à un calculateur du système d'antiblocage.  There already exist in the state of the art, systems of this type which comprise a target associated in rotation with the wheel of the vehicle and a corresponding sensor adapted to deliver a rotational speed information of the wheel to a computer of the system. antilock.

Dans les systèmes de l'état de la technique, la cible est formée sur une pièce rapportée par exemple sur le moyeu de la roue et le capteur est disposé axialement par rapport à cette cible pour détecter par exemple des indentations axiales de cette cible et délivrer un signal correspondant.  In systems of the state of the art, the target is formed on an insert for example on the hub of the wheel and the sensor is disposed axially with respect to this target to detect, for example, axial indentations of this target and to deliver a corresponding signal.

On conçoit cependant que cette structure présente un certain nombre d'inconvénients, notamment au niveau du nombre de pièces utilisées, de son montage et de son encombrement.  However, it is understood that this structure has a number of disadvantages, particularly in terms of the number of parts used, its assembly and its size.

Le but de l'invention est donc de résoudre ces problèmes.  The object of the invention is therefore to solve these problems.

A cet effet, l'invention a pour objet un système d'antiblocage de roue pour véhicule à deux roues de type scooter, comportant une cible associée en rotation à la roue du véhicule et un capteur correspondant pour délivrer une information de vitesse de rotation de la roue, caractérisé en ce que la cible est formée par une portion périphérique crénelée d'un disque de frein associé à la roue et en ce que le capteur est disposé radialement en regard de cette portion périphérique crénelée du disque.  To this end, the subject of the invention is a wheel anti-lock system for a scooter-type two-wheeled vehicle, comprising a target associated in rotation with the wheel of the vehicle and a corresponding sensor for delivering a rotational speed information of the wheel, characterized in that the target is formed by a crenellated peripheral portion of a brake disk associated with the wheel and in that the sensor is disposed radially facing this crenellated peripheral portion of the disk.

Suivant des modes particuliers de réalisation, le système comporte une ou plusieurs des caractéristiques suivantes: - la portion périphérique crénelée du disque est obtenue par découpe par emboutissage de celui-ci; le capteur est porté par un support relié à un jambage de fourche du véhicule; et - le capteur est porté par un support relié à un étrier de frein associé au disque.  According to particular embodiments, the system comprises one or more of the following characteristics: the crenellated peripheral portion of the disk is obtained by cutting by stamping it; the sensor is carried by a support connected to a fork leg of the vehicle; and the sensor is carried by a support connected to a brake caliper associated with the disk.

L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels: - la Fig. 1 représente une vue en perspective d'un premier exemple de réalisation d'un système d'antiblocage de roue selon l'invention; et - la Fig. 2 représente une vue de côté illustrant un second exemple de réalisation d'un tel système.  The invention will be better understood from the following description given solely by way of example and with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a first embodiment of an anti-lock wheel system according to the invention; and - FIG. 2 shows a side view illustrating a second embodiment of such a system.

On a en effet illustré sur la figure 1, une roue, par exemple avant, d'un véhicule à deux roues de type scooter par exemple.  It has indeed shown in Figure 1, a wheel, for example before, a two-wheeled vehicle like scooter for example.

Cette roue est désignée par la référence générale 1 et est portée par exemple par une fourche désignée par la référence générale 2.  This wheel is designated by the general reference 1 and is carried for example by a fork designated by the general reference 2.

Cette roue est également associée à au moins un disque de frein désigné par la référence générale 3, lui-même associé à un étrier de frein de type classique désigné par la référence générale 4, porté par exemple par l'un des jambages de la fourche désigné par la référence générale 5.  This wheel is also associated with at least one brake disc designated by the general reference 3, itself associated with a brake caliper of the conventional type designated by the general reference 4, worn for example by one of the legs of the fork designated by general reference 5.

De façon classique, ce systèrne d'antiblocage de roue comporte une cible associée en rotation à la roue du véhicule et un capteur correspondant pour délivrer une information de vitesse de rotation de la roue.  In a conventional manner, this anti-lock wheel system comprises a target associated in rotation with the vehicle wheel and a corresponding sensor for delivering information on the speed of rotation of the wheel.

Selon l'invention, la cible est formée par une portion périphérique crénelée du disque de frein 3 associé à la roue 1, cette portion crénelée étant désignée par la référence générale 6 sur cette figure 1.  According to the invention, the target is formed by a crenellated peripheral portion of the brake disk 3 associated with the wheel 1, this crenellated portion being designated by the general reference 6 in this FIG.

De plus, le capteur correspondant désigné par la référence générale 7 sur cette figure, est disposé radialement en regard de cette portion périphérique crénelée 6 du disque, pour être en regard des indentations radiales de celle-ci.  In addition, the corresponding sensor designated by the general reference 7 in this figure, is arranged radially facing this crenellated peripheral portion 6 of the disk, to be opposite the radial indentations thereof.

Dans l'exemple illustré sur cette figure 1, le capteur est porté par un support associé au jambage de fourche 5.  In the example illustrated in this FIG. 1, the sensor is carried by a support associated with the fork leg 5.

Bien entendu, d'autres dispositions de ce capteur peuvent être envisagées, comme cela est illustré sur la figure 2, dans laquelle des numéros de référence identiques désignent des pièces identiques ou analogues à celles illustrées sur la figure 1.  Of course, other arrangements of this sensor can be envisaged, as illustrated in FIG. 2, in which like reference numerals designate parts that are identical or similar to those illustrated in FIG.

C'est ainsi en effet que l'on reconnaît sur cette figure 2, la roue 1, la fourche 2, le disque de frein 3, l'étrier 4, le jambage de fourche 5, la portion crénelée 6 du disque et le capteur correspondant désigné par la référence générale 7.  This is indeed what is recognized in Figure 2, the wheel 1, the fork 2, the brake disc 3, the stirrup 4, the fork leg 5, the crenellated portion 6 of the disc and the sensor correspondent designated by general reference 7.

Cependant, sur cette figure 2, le capteur 7 n'est plus porté par un support relié au jambage de fourche mais par un support associé à l'étrier de frein 4.  However, in this FIG. 2, the sensor 7 is no longer carried by a support connected to the fork leg but by a support associated with the brake caliper 4.

Bien entendu, d'autres dispositions encore peuvent être envisagées.  Of course, still other arrangements can be envisaged.

On notera que de préférence la portion périphérique crénelée 6 du disque de frein 3 est obtenue par découpe par emboutissage de celui-ci, cette portion étant alors venue de matière avec le reste de ce disque.  Note that preferably the crenelated peripheral portion 6 of the brake disc 3 is obtained by cutting by stamping thereof, this portion then being integral with the rest of this disc.

On notera également que le capteur peut quant à lui être, de façon 5 classique, par exemple un capteur à effet Hall ou autre.  It will also be appreciated that the sensor may be, for example, typically a Hall effect sensor or the like.

On conçoit alors qu'une telle structure présente un certain nombre d'avantages, notamment au niveau du nombre de pièces et de l'encombrement réduits d'un tel système.  It is conceivable that such a structure has a number of advantages, particularly in terms of the number of parts and the reduced size of such a system.
