Abstract

The flexible crankshaft (4) for software controllable aircraft wheel drive represents a steel flexible cable (4), located in a flexible plastic-rubber guide which is adapted for the transfer of the torque along all axis, and is connected on one end to a power distributor (11), (or directly to a power generator unit if the construction is with one wheel) and with the other end, i.e. a small drive adapter (5), rests on the tyre of the aircraft wheel. The power distributor (11) receives entry power from the power generator motor (10) (electrical motor with gearshift switches, couplings, etc. Or from air pressure in "pneumatic" construction). The flexible crankshaft rotates moved by the power distributor or the motor (across the redactor, multiplicators, gearshift, valves, couplings, etc.) and transfers the torque through the adapter, to the tyre wheel itself, and in this way rotation of the wheel occurs. The rotation speed is regulated with the aid of a program CPU or own microcontroller, and always turns the wheel at the exact program calculated optimal rotation speed, adjusted for landing.
