Experimental tests on rolling resistance of road wheels in rubber tracked undercarriages

Abstract eng:
Double flange road wheels are often applied in undercarriages with rubber tracks and belts because of numerous advantages. Research on energy efficiency of rubber track systems conducted by the Department of Off-Road Machine and Vehicle Engineering (Wrocław University of Science and Technology) indicates that the amount of energy lost due to interaction between double flange roller and rubber track or belt is influenced by contact pressure distribution between the roller and the track. In order to minimize motion resistance of the rollers, the pressure distribution should be possibly uniform, which has been shown in the following article on the basis of experiments. Consequently, it might be concluded that application of suspension systems enabling double flange rollers to oscillate in transverse vehicle plane might contribute to an increase in energy efficiency of undercarriages with rubber tracks and belts.
