Description
La présente invention concerne un capteur de vitesse, notamment pourThe present invention relates to a speed sensor, particularly for
véhicule à deux roues de type scooter. two-wheeled scooter type vehicle.
Dans l'état de la technique, les véhicules à deux roues de type scooter sont généralement équipés d'indicateurs de vitesse et d'odomètres électroniques qui nécessitent un capteur de vitesse de rotation notamment de la roue avant du véhicule. In the state of the art, scooter-type two-wheeled vehicles are generally equipped with speed indicators and electronic odometers that require a speed sensor, in particular the front wheel of the vehicle.
Ces capteurs sont très souvent des dispositifs électromécaniques en-traînés par la roue et délivrant des impulsions dont par exemple la fréquence est proportionnelle à la vitesse du véhicule. These sensors are very often electromechanical devices dragged by the wheel and delivering pulses whose frequency, for example, is proportional to the speed of the vehicle.
On conçoit cependant que ceci présente un certain nombre d'inconvénients en raison de l'utilisation de tels dispositifs électromécaniques. However, it is understood that this has a number of disadvantages because of the use of such electromechanical devices.
En effet, de tels dispositifs sont relativement complexes, non seule-ment à fabriquer, mais également à monter, et sont par ailleurs fragiles. Indeed, such devices are relatively complex, not only to manufacture, but also to mount, and are otherwise fragile.
En effet, du fait de leur emplacement, ces capteurs sont régulièrement soumis à des agressions de l'environnement extérieur. Indeed, because of their location, these sensors are regularly subjected to attacks from the outside environment.
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 capteur de vitesse, notamment pour véhicule à deux roues de type scooter, caractérisé en ce qu'il comporte une cible magnétique, portée par une portion d'une jante d'une roue du véhicule, de manière à se déplacer en regard d'un détecteur correspondant, porté par une pièce formant entretoise, fixe en rotation et placée entre la jante de roue et un bras de fourche du véhicule. For this purpose, the subject of the invention is a speed sensor, in particular for a scooter-type two-wheeled vehicle, characterized in that it comprises a magnetic target carried by a portion of a rim of a vehicle wheel. , so as to move with respect to a corresponding detector, carried by a spacer-forming piece, fixed in rotation and placed between the wheel rim and a fork arm of the vehicle.
Suivant d'autres caractéristiques de l'invention: - le détecteur est noyé dans la pièce formant entretoise lors de la fa-25 brication de celle-ci par moulage; - le détecteur est un détecteur à effet Hall; - la cible est placée dans un logement de réception d'un roulement de roue du véhicule; la portion de jante portant la cible magnétique est en saillie axiale 30 dans une gorge correspondante de la pièce formant entretoise, pour former des moyens de protection du capteur et du roulement; - la cible est fixée sur la portion de jante par collage; - la cible est fixée sur la portion de jante par frettage. According to other characteristics of the invention: the detector is embedded in the spacer part when the latter is molded; the detector is a Hall effect detector; the target is placed in a housing for receiving a wheel bearing of the vehicle; the rim portion carrying the magnetic target is projecting axially in a corresponding groove of the spacer piece to form sensor and bearing protection means; the target is fixed on the rim portion by gluing; - The target is fixed on the rim portion of the rim.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant au dessin annexé qui représente une vue en coupe d'une portion de roue avant d'un véhicule équipée d'un capteur selon l'invention. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawing which shows a sectional view of a front wheel portion of a vehicle equipped with a sensor according to the invention.
On a en effet illustré sur cette figure, une portion d'une roue avant de véhicule à deux roues de type scooter. It has indeed shown in this figure, a portion of a front wheel of a two-wheeled vehicle scooter type.
On reconnaît en effet sur cette figure, une portion de jante de roue dé-signée par la référence générale 1, et une portion de bras de fourche désignée par la référence générale 2. In this figure, a wheel rim portion deregistered by the general reference 1 is recognized, and a fork arm portion designated by the general reference 2.
On reconnaît également sur cette figure, un axe de roue désigné par la référence générale 3, et un roulement de roue désigné par la référence générale 4, interposé entre cet axe et la jante de la roue et disposé dans un logement de cette jante. This figure also recognizes a wheel axle designated by the general reference 3, and a wheel bearing designated by the general reference 4, interposed between this axis and the rim of the wheel and disposed in a housing of this rim.
Selon l'invention, le capteur de vitesse comporte une cible magnétique désignée par la référence générale 5 sur cette figure, qui, dans l'exemple décrit, est portée par une portion de la jante dans le prolongement du logement de roulement de roue. Cette portion de jante désignée par la référence générale 6 est par exemple en saillie axiale dans une gorge 7 d'une pièce formant entretoise 8, fixe en rotation et placée entre la jante de roue et le bras de fourche. According to the invention, the speed sensor comprises a magnetic target designated by the general reference 5 in this figure, which, in the example described, is carried by a portion of the rim in the extension of the wheel bearing housing. This rim portion designated by the general reference 6 is for example projecting axially in a groove 7 of a spacer part 8, fixed in rotation and placed between the wheel rim and the fork arm.
Cette disposition permet alors de former des moyens cle protection du roulement 4, en constituant par exemple une chicane devant le logement de réception de ceux-ci. This arrangement then makes it possible to form bearing protection means 4, for example by constituting a baffle in front of the receiving housing thereof.
La cible magnétique est alors placée de manière à se déplacer en regard d'un détecteur correspondant désigné par la référence générale 9. The magnetic target is then positioned to move opposite a corresponding detector designated by the general reference 9.
Ce détecteur est par exemple noyé dans l'entretoise lors de la fabrication de celle-ci par moulage, et peut pair exemple être formé par un détecteur à effet Hall. This detector is for example embedded in the spacer during manufacture thereof by molding, and may for example be formed by a Hall effect detector.
La cible est alors placée dans le logement de réception du roulement de roue du véhicule et peut par exemple être fixée sur la portion en saillie par 30 collage ou encore par frettage. The target is then placed in the receiving housing of the wheel bearing of the vehicle and may for example be fixed on the projecting portion by gluing or by hooping.
Cette cible peut par exemple être constituée par un airnant, par exemple en plasto-ferrite. This target may for example be constituted by an airnant, for example plasto-ferrite.
On conçoit alors qu'une telle structure présente un certain nombre d'avantages, notamment au niveau de la protection non seulement du capteur, mais également du roulement de roue. It is conceivable that such a structure has a number of advantages, particularly in terms of protection not only of the sensor, but also of the wheel bearing.
Par ailleurs, aucune pièce de transmission de mouvement n'est utili-5 sée dans ce capteur, ce qui permet d'en améliorer la fiabilité. Moreover, no motion transmission part is used in this sensor, which makes it possible to improve its reliability.
Le détecteur peut alors être relié de façon classique par exemple par des conducteurs électriques désignés par la référence générale 10, au reste des circuits du véhicule. The detector can then be connected in a conventional manner for example by electrical conductors designated by the general reference 10 to the rest of the circuits of the vehicle.
Bien entendu, d'autres modes de réalisation encore peuvent être envisagés. Of course, other embodiments may be envisaged.
