CONTROL DEVICE DRIVE MECHANISM Russian patent published in 2024 - IPC F16H37/08 F16H48/00 F16D27/00 

FIELD: machine building.

SUBSTANCE: control device drive mechanism includes two electric motors with reduction gears, an output link, a differential mechanism with a central shaft, two stops, at least two mechanical switches, a return spring, an electromagnetic clutch, two self-braking worm gears and a power reduction gear. Input shaft of the power reduction gear is connected to the central shaft of the differential mechanism through an electromagnetic clutch which includes an electromagnet with two excitation windings, a spring-loaded armature, two cam half-couplings, one of which is installed on the input shaft of the power gear, and the other half-coupling is rigidly fixed on the armature. Output link is made in the form of a lever and is rigidly fixed on the output shaft of the power reduction gear with the possibility of rotation between the stops. One end of the return spring, which is a torsion spring, is connected to the housing, and the other end is connected to the output shaft of the power reduction gear. Every motor is connected with differential gear via self-braking worm gear. Cam is installed on the shaft connected to the input and output shafts of the power reduction gear. Gear ratio between shafts of power reduction gear is greater than gear ratio between cam shaft and input shaft of power reduction gear.

EFFECT: improved operational characteristics and high functional reliability.
