AND ELASTOMETRIC TRACK

Industrial vehicles with undercarriage with elastomeric tracks are frequently used in agriculture and forestry, which is connected with moving on deformable ground. A friction method of transmitting the drive between a drive pulley and a track, which is often applied, is sensitive to adverse ambient conditions, whereas the influence of the ground on friction feedback conditions in the area of the ground working on the drive system is significant. Deformable ground may be a source of contamination, which considerably reduces a friction coefficient on wrap of a drive pulley. The article includes the analysis of deformable ground influence on the volume of driving moment transmitted between a drive pulley and elastomeric track. It has been demonstrated that the influence of deformable ground, as a result of additional pressures working on wrap of a drive pulley may, in some circumstances, considerably increase the moment transmitted by means of friction feedback of a drive pulley with elastomeric track. Increase of driving moment may be higher than 50%. The analysis includes limited applicability of Euler and Entelwein’s law in the description of transmitting the moment between a drive pulley with elastomeric lining and elastomeric track
