Ways of redistribution of power loads on supporting surfaces of machine-tractor unit

Abstract

Reducing energy costs when using mechanization tools for crop growing is currently a priority for agricultural producers of all forms of ownership. This directly affects the formation of the cost of the resulting product, and, therefore, its competitive ability. At the same time, the main direction of reducing energy costs when growing crops is the use of multi-operation mechanization tools that allow performing several operations at once. This, in turn, as a result, increases the total amount of mechanization tools used, which undercarriages negatively affect the state of the physical and mechanical soil properties. This is especially true for single-axle trailed mechanization implements used in crop growing technology. During the operation of such machines, as the operation is performed, their center of gravity changes due to a change in the total mass, and this affects the distribution of power loads in the supporting bases of the machine and tractor unit used, and in particular the coupling weight of the powertrain. In this regard, it becomes necessary to develop a device that solves the above problem. The studies made it possible to obtain a theoretical dependence of the influence of the proposed device on the redistribution of the power load on the supporting bases of the powertrain and a single-axle trailed machine which allows using it to determine the power load of the soil on the rear (transmitting torque) wheels of the powertrain in the absence of a trailed bogie taking into account the power load on the rear (transmitting torque) wheels of the powertrain created by itself, take into account the power load transmitted to the rear (transmitting torque) wheels of the powertrain from the trailed bogie, take into account the effect of the total weight of the trailer unit, the position of its center of gravity; position of the movable support, and overall size of the trailed bogie.
