Abstract
The article poses a scientific problem, which is solved by using electromechanical mechanisms with an automatic control scheme and tracking the tension of the caterpillar within the required limits. The analysis of scientific papers revealed a number of disadvantages that are inherent in tracked propellers with existing track tensioning mechanisms: a significant drop in the efficiency at high speeds of a track with a rubber-metal hinge due to high stretching coefficients, which leads to a decrease in the coefficient of adhesion of the track; significant deterioration in maneuverability due to the possibility of the decrease of the track from the idler wheel under certain conditions; the inability to change the tension of the tracks when turning the machine, the inability to automatically respond to a change in the type of soil. Summing up the results of the literature review on the topic, we can single out a part of the previously unsolved problem, namely: the problem of matching the track tension to the external and internal operating conditions of the tracked mover is multifactorial, and its solution is a complex technical problem. Such mechanisms use widely adjustable DC motors with built-in electromagnetic brakes. It is obvious that the installation of these electric motors will provide the necessary speed, automatic or in accordance with the signals of the human operator, the necessary regulation of the tension of the tracks. which will significantly increase the controllability of the tracked vehicle at high speeds, significantly increase the patency of the tracked vehicle, obtain a positive effect on the dynamic performance of the tracked vehicle, achieve the maximum increase in the maximum speed, increase the efficiency of the tracked propeller up to 10% depending on the driving conditions by reducing the caterpillar bypass, reduce fuel consumption by up to 6% by increasing the efficiency of the caterpillar mover, increase the durability of the tracks.
