In the transmission of the 1.4 drawbar category mobile power vehicle on the performance indicators of machine and tractor units

Abstract

The aim of the work is to scientifically substantiate a way to improve the technical, economic and agrotechnological performance indicators of machine-tractor units, compiled on the basis of traction power equipment of category 1.4, the main technological operations in the cultivation of various crops by reducing the level of dynamic processes in their connections. It is established that the elastic damping mechanism with nonlinear characteristics and optimal parameters installed in front of the drive shaft of the power transmission of a traction power tool of category 1.4 provides favorable conditions for the functioning of all links of machine-tractor units for agricultural purposes, with them the main technological operations are performed, which contributes to the improvement of its technical, economic and agrotechnological indicators. The installation of an elastic-damping mechanism with nonlinear characteristics and optimal parameters in front of the drive shaft of the tractor traction category 1.4 provides an increase in productivity by more than 8% while reducing specific fuel consumption by 9% or more, as well as improving the quality performance of machine-tractor units when they perform basic technological operations.
