To eliminate this effect, before installing the steel bar 4 and filling with filler 6, the inner surface of the load-bearing elements is covered with liquid rubber (not shown).

  • the inner surfaces of the power elements 1, 2, 3 are covered with liquid rubber by cold spraying through technological holes located on the surface of the power elements.
  • a steel bar 4 is installed in the power element through the technological hole with centering elements 5 placed on it, giving the bar a preliminary shape of the power element. Then, at the points of contact of 8 steel bars with each other, they are welded.
  • the proposed technical solution for the design of the load-bearing cage of the passenger compartment is also applicable for strengthening the cabin of a cargo vehicle and the passenger compartment of a bus.
  • the monolithic rigid and durable load-bearing frame of the vehicle interior increases its passive safety. In any collision - frontal, side, rear impact, the displacement of the vehicle's structural elements into the passenger compartment will be absent or minimized. This will not only reduce the severity of bodily injury, but also help save human lives.

Abstract

Ce modèle d'utilité se rapporte au domaine de la construction automobile, concerne notamment un dispositif de carrosserie avec une carcasse de force de l'habitacle sous forme d'une structure tridimensionnelle faite d'éléments de force creux soudés entre eux (1, 2, 3), et a pour but d'augmenter la sécurité du conducteur en cas d'évènement lors de la conduite sur route. Dans chacun des éléments (1, 2, 3) se trouve une barre en acier (4) ayant une surface striée. Des éléments de centrage (5) assurent le positionnement de la barre (4) en termes d'orientation par rapport au centre de l'élément de force. Les barres (4) aux endroits de contact (8) les unes avec les autres sont connectées par soudure. L'espace libre entre les éléments (1, 2, 3) est rempli d'une matière de charge (8) consistant en du plastique structurel préalablement chauffé jusqu'à l'état d'écoulement. La surface interne des éléments (1, 2, 3) est recouverte de caoutchouc liquide afin d'exclure tout jour entre ces derniers et la matière de charge (6). La carcasse de force de l'habitacle du moyen de transport consiste en une cellule de force rigide et d'une grande résistance de protection contre l'écrasement et les explosions en cas d'accident. On augmente ainsi la sécurité passive du moyen de transport.
