TRAILER Russian patent published in 2017 - IPC B60D1/00 A01B61/02 A01B59/06 

FIELD: agriculture.

SUBSTANCE: trailer contains 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, are rigidly connected with the tractor frame. To the transversal adjustment bar the inertial damper frame is rigidly fixed. 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 to the pressure disc via the friction disc with adjusting the impact force from the adjusting screw with the spring through the clamping fork with a ball bearing.

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