Abstract

The device has reflectors (1) installed on brake calipers, and sensors (2) installed at a running gear on a support parallel to a chassis of a motor vehicle. The sensors determine a gap separating the sensors, and cables (6) connect the sensors towards a microcontroller (3) which exactly calculates position of wheels of the vehicle. The microcontroller sends the calculated data towards a sound producing unit and to a display (4) which permits the visual reading of the data.

Description

La présente invention concerne un dispositif permettant d'être informé àThe present invention relates to a device for being informed at

tout moment sur l'alignement (parallélisme) des roues d'un véhicule depuis l'habitacle pendant la conduite. Plus précisément sur leurs positions par rapport à des lignes verticales et parallèles imaginaires sous chaque roue. L'alignement des roues  any time on the alignment (parallelism) of the wheels of a vehicle from the cockpit while driving. More precisely on their positions relative to imaginary vertical and parallel lines under each wheel. Wheel alignment

pendant la conduite doit être parfait et selon les côtes du constructeur du véhicule bien sûr.  while driving must be perfect and according to the ribs of the vehicle manufacturer of course.

Un défaut de parallélisme entraîne une augmentation de la consommation de carburant du fait que le moteur doit exercer une force plus importante pour entraîner les roues du véhicule et surtout une usure irrégulière et prématurée des pneumatiques coté intérieur ou extérieur selon le défaut du train avant. Ce système permet donc de pouvoir le constater dès que le défaut est perçu par l'électronique, sans avoir besoin de connaissance technique dans ce domaine. A ce jour, il n'existe aucun moyen de se rendre compte immédiatement de ce problème. C'est seulement lorsque le pneu a commencé à s'user irrégulièrement que l'on constate ce dérèglement, mais il est déjà trop tard.  A lack of parallelism leads to an increase in fuel consumption because the engine must exert a greater force to drive the wheels of the vehicle and especially uneven and premature tire wear on the inside or outside of the tire according to the defect of the front axle. This system makes it possible to be able to see it as soon as the defect is perceived by the electronics, without needing any technical knowledge in this field. To date, there is no way to immediately realize this problem. It is only when the tire has begun to wear off irregularly that we notice this disturbance, but it is already too late.

Le but de cette invention est d'informer le conducteur dès l'instant où le problème est présent, afin de faire régler rapidement le train chez un spécialiste, ce qui évite des frais plus élevés de carburant et ceux liés à l'usure prématurée et uniforme des pneus qui sont beaucoup plus conséquents.  The purpose of this invention is to inform the driver as soon as the problem is present, in order to quickly adjust the train to a specialist, which avoids higher fuel costs and those related to premature wear and tear. uniform tires that are much more consistent.

Le système comporte en effet selon une première caractéristique: Des moyens de réflexion installés sur les étriers de freins ou sur l'endroit le plus adapté selon le véhicule en face, des moyens de détection et de mesure servant à déterminer l'écart séparant ces derniers installés au train roulant sur un support parallèle au châssis du véhicule, un moyen de réflexion servant de repère logé dans la colonne de direction installé sur l'axe du volant croise un moyen de détection et de mesure, par rapport aux informations envoyées par ce dernier ainsi que celles envoyées par les autres moyens de dits détection et mesure tous reliés entre eux par un moyen de connexion jusqu'au moyen de traitement de données qui effectue un calcul exact de la position des roues puis renvoie ces données sur moyen de production sonore non illustré sur le dessin et sur un afficheur relié au système sous forme éventuellement de bip sonore suivi d'un message d'alerte, un moyen de nettoyage non illustré adapté au dispositif sert a nettoyer les dits moyens de réflexion et les dits moyens de détection et de mesure.  The system comprises in fact according to a first characteristic: reflection means installed on the brake calipers or on the most suitable place according to the vehicle in front, detection and measurement means for determining the difference separating them installed in the running gear on a support parallel to the chassis of the vehicle, a reflection means serving as a marker housed in the steering column installed on the axis of the wheel crosses a detection and measurement means, compared to the information sent by the latter as well as those sent by the other means of said detection and measurement all interconnected by means of connection to the data processing means which performs an exact calculation of the position of the wheels and then returns these data on means of sound production not illustrated on the drawing and on a display connected to the system in the form of beep sound followed by a warning message, a means of non-illustrated cleaning adapted to the device serves to clean said so-called reflection means and said detection and measurement means.
