ABSTRACT:
The remote-control device features a servomechanism that transmits the movements of a first control cable or tie rod, which is connected to handgrip or control pedal, to a second cable or tie rod which is connected to an application. The servomechanism features two neutral levers with bodies having a cylindrical sector. The levers are connected, respectively, to the cables or tie rods. This servomechanism features a shaft of a geared motor which is arranged coaxially between two bodies of the levers, features a spiral spring arranged between the two bodies and the shaft, and is tightly wound on the shaft. The spring has opposing ends which face outward and extend between the bodies. The servomechanism further features a transducer which detects the movements of first control cable and actuates an electronic unit which controls the geared motor in such a way that the remote control can be effected electromechanically or, in the event that the electrical components malfunction, mechanically.
