DISTRIBUTION-CORRECTING DRAWBAR FOR A SEMI-FRAME TRACTOR Russian patent published in 2022 - IPC B60B39/00 B62D53/04 

FIELD: auxiliary devices.

SUBSTANCE: invention relates to additionally installed auxiliary devices to reduce tractor slippage. The distributing-correcting traction coupling device for a semi-frame tractor is made in the form of a set of two curly rods connected by a cardan joint at the point of horizontal displacement of the semi-frames in a turn. The end of the first figured link is bolted in the central part of the transverse beam, installed in the technological holes of the brackets on the lower part of the front semi-frame of the tractor and additionally fastened to the semi-frame with a supporting bracket. The second rod passes under the lower part of the rear half-frame, supported by a support bracket. At the end of the second thrust, a towing device of the “draw fork” type is installed.

EFFECT: uniform distribution of the weight load of the trailer on the supports of the coupled tractor in motion is achieved to reduce slippage, increase tractive effort and agricultural maneuverability, stabilize the unit in motion, increase the productivity and safety of operation of the coupled wheeled semi-frame tractors.
