САЖЕТАК / ABSTRACT:
Wheel loaders are mobile machines where vibrations occur during transport of loaded material. One common cause is an imbalance in the load being carried, especially when the load is unevenly distributed in the bucket, when the center of gravity shifts. Paper presents the concepts of hydrostatic systems for vibration regulation of the wheel loaders during transport of loaded material in working cycle of the machine. The motion regulation is based on the ability to change the volume of the hydraulic oil in the hoses and in hydro-cylinders for manipulation of the wheel loader’s arm. Whereby, hydro-cylinders of arm are acts as a „hydraulic spring“, whose dynamic characteristics is changing by the change of hydraulic oil volume thus stabilizing the movement of the machine.
