Definitions

  • the present invention relates to a rail transport system supported by hydraulic fluid, where all the mass, without energy consumption for its floating, floats on the fluid, making the friction and friction of the conventional model negligible. by rail.
  • the fluid that supports the full weight of the train remains trapped and under pressure in a piston that slides inside a rail. All the weight of the train will be distributed over the hydraulic fluid, free of friction as well as free of wear. It also proposes a simple solution, which eliminates air resistance in low-speed train.
  • the system is comprised of a pair of rails both having a U-shape, 90 ° inclined throughout. Their openings face each other. These rails must withstand the pressure of the fluid that is caused by the weight of the train, which pressure is distributed on its contact surface.
  • Figure 2 in a top view, represents two rectangular shaped pistons that are connected by two axes, forming a single piece.
  • the pistons are inside the sides of the rails that have a cut in their upper part for better understanding.
  • the areas with curved lines on the pistons represent longitudinally concave hydraulic fluid reservoirs on their upper surface, and on their inner surface there are identical reservoirs.
  • Four rollings attached to the ends of the pistons guide them laterally into the track. Since the side guides do not support any weight, only by guiding the train laterally, friction and wear will be negligible and thus very efficient.
  • FIG. 3 in front section shows the two pistons connected by the shaft inside the rail.
  • Each piston has two concave shaped longitudinal fluid reservoirs.
  • the concave reservoirs on each piston are arranged opposite each other and are opened on their upper and lower surfaces.
  • the fluid contained in the outer reservoirs will connect to the upper piston reservoirs.
  • the upper piston reservoirs will connect to the lower ones.
  • the pressure caused by the weight of the train will act to keep the pistons "floating" between the hydraulic fluid inside the track.
  • the hydraulic pressure in the external reservoir as well as in the lower and upper pistons will be identical. They should fit extremely precisely inside the tracks, as they will run a millimeter distance from them, which should prevent the flow of fluid.
  • the volume of the lower piston shells shall be calculated to be slightly larger than the upper pistons and shall nullify the pressure exerted by the piston weight. In this way the weight of the train presses the fluid at its base, which presses the upper piston reservoirs, which press the lower, causing fluctuation.
  • the present invention in addition to low production costs and low energy consumption, will have low maintenance costs due to the large contact surface of the fluid and the absence of wear. caused by friction. It will serve different purposes, therefore, the diversity of designs and dimensions of the pistons and rails will provide curves with reduced degrees for urban routes. Both low-speed urban transport, long-haul routes and even a high-speed train can be developed.

Abstract

L'invention concerne un système de transport sur rails à sustentation par fluide hydraulique, caractérisé en ce que toute la masse du système flotte sur le fluide, sans consommation d'énergie pour la flottaison, le mécanisme agissant de manière à supprimer le frottement et l'usure causée par les pièces mécaniques mobiles supportant une grande masse en mouvement linéaire, ledit système comprenant en outre un système d'aspiration et d'accélération de l'air à travers des conduits, favorisant l'élimination de la résistance de l'air lorsque des vitesses élevées sont atteintes. Les domaines techniques auxquels la présente invention est destinée sont notamment les secteurs industriels ainsi que le transport ferroviaire.
