<p>The invention concerns a design for a vehicle wheel characterised in that it consists in adapting double straight or convex blades over their whole length or width joined together on the edges of each fin, so as to form a V-shaped angular space capable of being curved into a U-shape in a specific direction sufficiently to absorb natural air pressure (wind) or that generated by the wheel displacement, to facilitate rotation thereby reducing driving force and saving energy (muscular or fuel). The invention also concerns a bicycle wheel design which consists in fixing the hub to rims with spokes or rods having triangular cross-section forming a hollow angular or curved space for harnessing air pressure when the wheel rotates in a predetermined direction.</p> |
