One of the wheeled tractors use effectiveness essential indicators in agricultural production is the indicator of their traction and grip qualities, due primarily to the interaction of the driving wheels with the rolling surface on different soil backgrounds and the slip coefficient. As the result of the wheel propellers interaction with the soil, the latter one is compacted and intensively destroyed. Uneven soil density increases traction resistance and increases the energy consumption for the machine-tractor unit movement (MTU). The possibility of the most effective reduction of hook load fluctuations corresponding to an intensive increase in slipping is provided by the elastic pneumohydraulic element, which has the ability to regulate optimal parameters in a wide range of elastic properties.

驱动轮运动数学模型
轮式拖拉机在农业生产中使用有效性的基本指标之一是其牵引力和抓地力的指标,这主要是由于驱动轮与不同土壤背景上的滚动表面的相互作用和滑移系数。由于轮式螺旋桨与土壤相互作用,后者被压实并严重破坏。不均匀的土壤密度会增加牵引阻力并增加机器-拖拉机单元运动 (MTU) 的能耗。弹性气动液压元件提供了最有效地减少与滑动强度增加相对应的吊钩负载波动的可能性,该元件能够在广泛的弹性特性中调节最佳参数。
