Abstract

In the article the necessity of tractor ballasting is over viewed. The analysis of interaction of traction force, forces of weight and slippage of the wheels is presented. A de-pendency of tractor slippage on coefficient of weight utili-zation for driving wheel grip is analyzed. An interaction between tractor ballasting and coefficient of weight utiliza-tion for driving wheel grip is investigated.Equations of dependencies of weight force transferred from front to rear wheel on tractor mass and coefficients of: weight utilization for wheel grip value of transferred weight and rolling resistance are presented. Method for tractor ballasting and setting the value of ballast mass is proposing. The nomogram for setting optimal value of bal-last mass and its fitting place, when medium instantaneous wheel slippage is known is presentedMethods of nomogram usage and revive of utilization possibilities are presented.
