IT1252887B - Automobile which simultaneously tilts the chassis L and the wheels M, N, O, P, shifting the weight internally to the curves via the joints A, B, C, D, E, F, G, H, I, the movable vertical steering ailerons S, T, and the movable horizontal negative-lift ailerons Q, R - Google Patents

Abstract

Different arrangement of the four wheels, two of which M, N are for reverse steering with vertical steering ailerons S, T and two are motorised wheels O, P at the centre, for support when tilting with the movable horizontal negative-lift ailerons Q, R. Placed on a circle, it faithfully follows it by virtue of the two wheels M, N, and the two support wheels O, P furnish a pivot for the steering movements, by tilting it in proportion to the velocity and the radius of the curve. By gradually reducing the tilt and the diameter of the circle down to the spacing of the two steering wheels M, N, the automobile turns on itself, reducing the manoeuvring space equal to its length without having to reverse from a parking space. There is dual steering thanks to the two wheels M, N and the tilting provides better sensitivity when steering. By shifting its entire weight inside the curve, the automobile avoids the risk of exceeding the tyre traction limits. Thanks to the greater load bearing on the wheels owing to the central movable negative-lift ailerons Q, R, it is possible to eliminate skidding of the tyres when coming out of a curve. In these situations, the driver's body is no longer subjected to lateral stresses. <IMAGE>
