Definitions

  • This utility model patent relates to the automotive industry to a warning device introduced in a motor vehicle belt, commonly referred to as a "toothed belt",
  • the timing belt is an extremely important part in a motor vehicle because it acts on the engine of the vehicle by connecting the camshaft to the crankshaft, synchronizing these two parts and causing the intake and exhaust valves to open and close. at the exact moment. It also maintains synchronism between the crankshaft (which transfers engine power to the wheels) and the camshaft (responsible for gas in and out of the cylinder).
  • valves begin to move in a disorderly manner and the pistons keep working (rising and falling) without criteria. The consequence can be catastrophic: pistons and valves can collide, causing valve bending and head damage.
  • Timing belts Today, due to the demands of modern engines, new materials and technologies have been introduced in the manufacture of timing belts in order to improve their performance and durability. Using high strength materials in their rubber compounds and special coatings that protect against external agents to meet these requirements (oils, ozone action, abrasion and heat); Fiberglass traction mesh and molded teeth with precise design and spacing.
  • the present patent is the solution to this problem.
  • This is a narrow strip arranged at the side of the belt, with the same profile as the belt, made of material 20% weaker than the original belt material, to break before the belt and activate a sensor that triggers the alert flashing provided in the vehicle dashboard.
  • the driver has time to stop in a workshop and change the belt avoiding inconvenience and expense with the vehicle, since turning on the flashes alerts the driver will know that the time to change it is approaching because of the mileage round or some engine problem that overloads belt operation.
  • timing belt warning device of a motor vehicle which is the subject of this patent can be better understood by referring to the accompanying figures, which even contain numerical references, together with the following detailed description, without, however, restricting their conformation. as to its dimensions, proportions and any types of finishes inserted.
  • Figure 1 is a front view of the front of the engine assembly showing the positioning of the timing belt with a schematic showing the sensor and its connection to the vehicle dashboard.
  • Figure 2 is a perspective view of a timing belt segment showing the warning band of the coupled device therein.
  • Figure 3 is a cross-sectional view of a belt carrying the band glued to its side.
  • the present invention relates to a motor vehicle timing belt warning device formed by a narrow warning strip (1) containing the same profile as the timing belt (2), Made of a material 20% more fragile than the material of the belt, which is glued to the side of the belt in all its extension.
  • Said toothed belt containing the narrowly pasted warning strip (1) which is monitored by an electrical sensor (3) disposed next to said narrow warning strip (1) to, through of a signal sent to the vehicle dashboard (4) in the form of a flashing light (5), the breakdown of the signal.
  • the warning strip (1) glued next to it, about 20% smaller than the material from which the original belt is made, when broken, triggers the sensor (3) next to it and alerts the driver of the for the imminent breaking of the timing belt (2) by means of a signal sent to a flashing led (4) arranged on the dashboard (.5) of the vehicle cab. In this way the driver can timely change the belt and avoid further damage to his vehicle.

Abstract

Le présent brevet de modèle d'utilité concerne une bande étroite disposée à côté de la courroie, avec le même profil que cette dernière, conçue en un matériau 20% plus fragile que le matériau d'origine de la courroie, de sorte que sa rupture intervienne avant celle de la courroie, ce qui évite la rupture inattendue de cette dernière. L'invention consiste en une bande étroite d'alerte (1) latéralement collée à la courroie dentée du véhicule, surveillée par un capteur électrique (3) joint à ladite bande étroite d'alerte (1), de manière à en indiquer la rupture au moyen d'un signal envoyé au tableau du véhicule (4), sous la forme d'un clignotement (5), ce qui permet au conducteur de changer la courroie en temps utile et d'éviter tout endommagement de son véhicule.
