Traktoriaus agregatų prikabinimo aukščio ir posūkio kampo įtaka ratų apkrovoms

Abstract

The main purpose for agricultural tractors are to pull variuos implements. Static and dyna-mic loads effecting tractor wheels are the basic factor for which varies tractor work efficiency and its performance. The bigger the static load the better wheel and surface interaction tractor can get. Tyre pressure markedly effects wheel and surface interaction. Moreover static load effects wheel slippage. Increasing static load you can reach smaller values of slippage. Thats why agricultural tractors are equipped with ballast weights. So this research is to find out dependence of tractor static wheel load distribution and pulling force, simulating pull of implement with variuos hitching heights and turn angles. Research shows that increasing pulling force, static load of rear wheels of tractor also increases and load from front wheels decreases.
