Definitions

  • the present invention generally relates to an automobile safety device, and more particularly to a safety device for preventing vehicle side deflection after a tire puncture.
  • BACKGROUND OF THE INVENTION With the construction of highways, the speed of running cars, and the cars running on expressways, the main cause of traffic accidents is the sudden explosion of tires during high-speed operation of automobiles, and the resulting traffic accidents account for major traffic accidents. The vast majority of highway traffic accidents cause heavy losses to people and property. According to some data, 70% of the traffic accidents caused by tires on Chinese highways are caused by punctures. In the United States, the proportion is as high as 80%. In a sense, the puncture has become the "number one killer" on the highway today.
  • the so-called puncture usually means that the tire loses most of the air in a short time (less than 0.1 second). As a result, the car is tilted, and the steering wheel is suddenly pulled by a great force to the side of the puncture. With a slight negligence, the steering wheel is not controlled, and the car will turn 360 degrees backwards. At this time, if the brakes are pressed due to tension, the consequences are even more unimaginable. Because the tires are exhausted, the combination with the steel ring becomes very loose, and the part of the tire that touches the road surface will be deformed and detached from the steel ring. In addition, when the brake is applied, the wheel on the side of the puncture has a large resistance and the speed is reduced to alkyne.

Abstract

L'invention concerne un dispositif de sécurité en cas d'éclatement d'un pneumatique de véhicule, comportant un moyen de détection d'éclatement d'un pneumatique, servant à détecter un signal indiquant l'éclatement du pneumatique, un moyen de commande servant à commander d'autres dispositifs en fonction du signal provenant du moyen de détection, et un moyen de freinage servant à empêcher une embardée du véhicule. Le moyen de commande est doté d'une borne d'entrée reliée à une borne de sortie de signaux du moyen de détection, et d'une borne de sortie reliée à une borne d'entrée de signaux du moyen de freinage. Lors de l'éclatement d'un pneumatique du véhicule équipé du dispositif de sécurité, le moyen de commande commande le moyen de freinage en fonction du signal transmis par le moyen de détection de façon à bloquer l'arbre de direction pendant un intervalle de temps déterminé. Le dispositif de sécurité permet donc d'éviter toute conséquence fâcheuse due à une mauvaise manoeuvre ou au lâcher du volant.
