SPRING-LEVER CORRECTOR OF ADHESION WEIGHT FOR WHEEL-TYRE TRACTORS Russian patent published in 2017 - IPC B62D53/04 A01B59/04 

FIELD: machine engineering.

SUBSTANCE: spring-lever corrector of the adhesion weight for the wheel-tyre tractor is designed as a trailer reloading device consisting of a hydrocylinder with a forked guide mounted on the bottom of the tractor transmission case, a U-shaped load frame mounted in the hinge of the bearing bracket with the middle part of the pull-rods, and a pressing unloading machine formed of two flat springs of the multi-leaf type, and a transmitting reactive thrust with the rubber bushings. In this case two flat springs are installed at the top and on the bottom of the front steering axle, their adjacent ends are connected through the eyelets by the transmitting reactive thrust with the rubber bushings, and the subsequent end of the upper spring with the eyelet is combined by the bolted joint to the pull rod upper section of the load frame, and the lower spring is installed in the hinge of the bearing bracket fixed by the bolted joints on the tractor frame.

EFFECT: invention increases the passability, resistance to turnover, operating and performance safety, reduces slipping of the wheel-tyre tractors.
