Description
Summary:The use of modern energy-rich equipment in agricultural production led to the increase in the operating speeds of machine-tractor aggregates (MTA), and, accordingly, to the further increase in dynamic loads in the engine-transmission unit. This also influenced the increase in hook load fluctuations relative to the average value up to 30 … 35%, which led to the occurrence of negative phenomena in the tractor running system interaction with the road. The installation of elastically damping elements in the tractor structure is one of the ways to reduce hook load fluctuations in the tractor transmission during road works [3, 6]. The presence of the elastic element in the tractor structure reduces the transmission shafts stiffness by 5 … 10 times. In this case, dynamic loads in transient modes are reduced by 1.1 … 1.28 times, and with the clutch sharp engagement - by 1.6 times.
