Traktoriaus padangų oro slėgio įtakos pasipriešinimo riedėjimui tyrimas

Abstract

The main purpose of this article was to investigate the dependance of tyre rolling resistance force according to the pressure and tarmac. Furthermore, fuel consumption is dependent on the speed and traction force on different driving surfaces. After analysing various literature sources it has been observed that the pulling force of the tractor depends on the wheel rolling resistance forces. Wheel rolling resistance force is dependent on the tractor bridges in the internal friction of rolling bearings; tire deformation; pavement; speed; tire structure, pressure and diameter. Experimental results show that increasing traction force fuel consumption also increases tractive effort. For example, at 7300 N, fuel consumption was 10.5 l/h. In the meadow, the maximum drawbar pull is at 1.2 bar tyre pressure at a speed of 1.67 m/s.
