TOROIDAL PROPULSION DEVICE FOR VEHICLES

WIPO Patent Application WO/1998/010975

A1

The present invention relates to a toroidal propulsion device for vehicles that comprises at least one resilient chamber (6) in the shape on a cylindrical sleeve having its ends turned inside out and sealed together. When filled with a pressurised fluid medium, the chamber (6) takes the shape of a singular torus comprising two internal layers (7, 8) as well as two opposite surfaces (9, 10), wherein said chamber (6) is mounted through the first of said surfaces on a support surface (11). The propulsion unit also comprises an endless driving belt (1) that extends between the two internal layers (7, 8) of the chamber, surrounds said chamber (6) on the side of its second external surface (9) and is brought into contact with driving rollers (3). The endless driving belt (1) is made in the shape of a hose connected to a source of pressurised fluid medium, wherein the cavity of said hose comprises two chambers (12, 13) for the fluid medium at an increased pressure. These chambers (12, 13) are joined to the toroidal resilient chamber (6) at the opposite ends thereof in the region of their initial contact with two diametrically opposed rollers (3), wherein said rollers are surrounded by the endless driving belt (1), one of them being rigidly mounted on the vehicle frame (2).
