The invention stems from the need to develop a suspension system as light as possible for a solar competition vehicle, where the lightweight of the systems represents a fundamental added value, all other functional conditions being equal.

The invention stems from the need to develop a suspension system as light as possible for a solar competition vehicle, where the lightweight of the systems underlies the added value, being all other functional conditions equal. The fiber joint appears as a single webbing with a ring connection complying with any pin of sufficient diameter to enter it. It offers the advantage of adapting more easily to almost all installation environments, while its price is approximately five times lower than that of the closest mechanical alternative. Thus, the patented joint is an innovative promising solution for the automotive industry and sports.

Applications:

  • Automotive and motorcycle industry (suspension, transmission and damping systems);
  • Precision mechanics (anti-tear arm safety systems, end-of-stroke systems such as damper spring and similar solutions).

 

Compared to conventional solutions, it has countless advantages:

  • Extreme lightness given the specific resistance;
  • Extreme resistance given the high yield strength compared to normal loads;
  • Low friction coefficient given the surface properties of the material;
  • Precision in the direction of transmission of forces due to flexibility;
  • Design flexibility due to the wide variety of models and sizes available;
  • Practical positioning given the simplicity of the fixing systems;
  • Economy, given the much lower prices.
