DEVICE TO REDUCE RIGIDITY OF TRANSMISSION OF MACHINE-AND-TRACTOR UNITS Russian patent published in 2005 - IPC

FIELD: mechanical engineering; machine building hydraulics.

SUBSTANCE: invention can be used on vehicles and machine-and-tractor units operating under unsteady conditions of movement. Proposed device contains planetary train 1, reactive link 3 connected with drive gear of oil pump 5. Planetary train is connected through carrier shaft with gearbox 9 and is set into operation by engine 11. Two-step adjustable restrictor 12 is installed in pressure main line of pump. Safety valve 14 and control cock 15 are connected to input of adjustable restrictor, being also installed in pressure main line of pump pneumohydraulic accumulator, being end member of pressure main line, is provided with three spaces. It consists of hydraulic cylinder, free piston, piston with rod, piston position regulator, oil line and oil channel. Space between pistons is filled with oil which regulates volume.

EFFECT: reduced influence of vibrations of external traction load onto functioning of machine-and-tractor unit.
