MECHATRONIC TOWING DEVICE Russian patent published in 2013 - IPC A01B59/06 

FIELD: agriculture.

SUBSTANCE: invention relates to a wheel tractor equipped with a mechanism of towing device with an elastic element, and can be used for different kinds of tillage operations. The mechatronic towing device comprises an elastic element of the multi-leaf type, a damping device filled with damping fluid. In the damping device a stepper motor is mounted, on a shaft of which a swivel washer with orifices is mounted and in the piston the orifices are made concentrically. The mechatronic towing device may comprise force sensors, a temperature sensor of the damping fluid, sensor of angle of position of the swivel washer relative to the piston, which are in turn a part of the adaptive system of adjustment of elastic-damping properties of the towing device. And the adaptive system of adjustment of elastic-damping properties of the towing device comprises a spectrum analyser, a microprocessor, and a principal controller of the stepper motor.

EFFECT: in the towing device the automatic adaptive adjustment of its elastic-damping properties is provided along with the expansion of the adjustment range.
