PURELY MECHANICAL DEVICE FOR CONTROLLING THE INCLINATION OF A TILTING VEHICLE HAVING AT LEAST THREE WHEELS

摘要

The invention relates to a purely mechanical device for controlling the inclination of a narrow tilting vehicle such as to guarantee equilibrium regardless of speed. The device is formed by a nacelle (1) suspended by two pivots (2 and 3) from two half-frames (4 and 5) that can be moved apart from the nacelle like the arms of a compass. A mechanical system (12) controls the respective angles of the two half-frames (4 and 5) and the nacelle (1). A steering system (16) allows a greater turning angle to be applied to the inner wheel than the outer wheel on turns and a correction is made by the mechanical system (14), by means of which the steered wheels (6 and 7) are toed-in or -out depending on whether the nacelle is over- or under-inclined in relation to its equilibrium. The device of the invention is particularly suitable for the production of narrow tilting vehicles, offering the circulation capabilities of a two-wheeled vehicle without the steering difficulties.
