Original abstract

The aim of the paper is an analysis of the measured and calculated force effects which act on tractor during tillage. Effects of the forces on individual driving wheels are analysed too. A mathematical model describing the transformation of force effect acting in the three-point linkage to loads in individual tractor wheels is developed. It is shown that the results of performed computations and theoretical analysis are in a good agreement. Based on the model, it is possible to use the measured force effects for precise determination of forces acting on the wheels. The influence of the length of the upper link on the loading of individual wheels and consequently on the traction performance of the tractor is determined.

Czech abstract

V článku je provedena analýza měřených a vypočtených silových účinků působících na traktor během orby. Ovlivnění síl působících na jednotlivá kola hnací kola je rovněž analyzován. Byl vyvinut matematický model, s jehož využitím je provedena transformace silových účinků působících v tříbodovém závěsu na zatížení jednotlivých sil. Je ukázán dobrý soulad provedených výpočtů s teoretickými analýzami. Na základě modelu je možné využít měřených sil k přesnému určení sil působících na kola. Byl určen vliv délky horního táhla na zatížení jednotlivých kol a následně na tahové vlastnosti traktoru.
