FIELD: agricultural engineering. ^ SUBSTANCE: proposed mechanism designed for balancing load to support surface of crawler tractor 1 by means of hydraulic system to control position of mounted implements 2 has distributor, regulator 7 and signal mixer 6. front and rear carriages 3, 4 of tractor running gear suspension from side of one of crawler gear sides is equipped with springs connected with flexible tie-rods 5 consisting of bar and sheathing. Deformation of springs is proportional to load on carriages. Bar is hinge-connected from one side to one balancer of carriage, and sheathing is connected to other balancer. Bar is connected from other side to power or positioning lever of signal mixer shaft, and sheathing is connected to signal mixer housing. Signal mixer is connected through mechanical tie-rod with control spool of regulator of position of rod of power cylinder 8 controlling operation of implement. ^ EFFECT: balancing of load between carriages of tractor, reduced compacting action of crawler gear on soil. ^ 1 dwg |
