Title : Assessment of energy losses of a drive wheel equipped with grass type tyres
Key words : tyre, traction efficiency, towing power, skid, rolling resistance, energy balance
Summary :

The study presents the results of traction experiments conducted on three sodded objects differing with seeds sowing norm. The objective of the paper was to compare traction abilities and energy losses of two tyres of different structures. For description of the research conditions, measurements of compactness, maximum shear stress and the moisture of sod soil were carried out. Values of the obtained forces and traction efficiencies were analysed, energy balance of wheels equipped with the researched tyres was also conducted. It was proved that the value of traction forces of wheels were comparable, but generated in a different manner. In case of 36x13.5-15 tyre - no relations between seeds sowing and traction efficiency were proved. 400x55-22.5 tyre could be better used for strength properties of subgrade and for achieving higher efficiency on facilities with a higher norm of seeds sowing. For 36x13.5-15 tyre higher demand for power supplied to the wheel was proved; more power was lost for the rolling resistance. For 400x55-22.5 tyre in order to obtain comparable traction force as for 36x13.5-15 tyre, lower demand for power and higher losses of power for skid were reported.
