MECHANISM OF TRACTOR HOOK FORCE DAMPING IN COMPOSITION OF MACHINE AND TRACTOR UNIT Russian patent published in 2017 - IPC A01B61/02 A01B59/06 

FIELD: agriculture.

SUBSTANCE: mechanism of the tractor hook force damping in the composition of the machine and tractor unit comprises a rigid, a flexible and a resilient power connection. The resilient power connection comprises a spring-type element attached on both sides by the brackets to the horizontal extension drawbars, which, in turn, are rigidly fixed on the tractor frame. In the resilient element center, the device for connection to the trailed machine is positioned. Support U-shaped arms embracing the spring, whose horizontal position is changed by the transversal adjustment bar, to which the inertial damper frame is rigidly fixed, are rigidly connected with the tractor frame. The inertial damper comprises the mechanical transmission made in the form of an inertial mechanism, having the flywheel rigidly fixed on the shaft, which via the flexible coupling is rigidly fixed on the gear cooperating with the rack supported by the clamping device. The gear rack is rigidly fixed on the device for connecting to the trailed machine, and the flywheel is connected by the butt with the brake device housing via the friction brake belt, with adjusting the force of the adjustment mechanism impact.

EFFECT: reduction of the MTU oscillation process during tillage operations.
