ACTIVE MONITORING OF COMPLEX ELEMENTS OF HYDROMECHANICAL TRANSMISSIONS
 OF MOBILE MACHINES

Abstract

The issues of active monitoring and diagnosing the technical condition of a mobile machine equipped with a hydromechanical
 transmission are reflected. The factors influencing the decrease in machine efficiency and the deterioration
 of transmission performance are considered. It is noted that the main processes contributing to the loss of performance
 of a hydromechanical transmission are friction and wear of the working surfaces of parts and their interfaces;
 fatigue processes in parts subject to variable loads; aging of materials The causes of defects and the nature of their
 manifestation in hydromechanical transmissions are given, as well as measures for continuous and active monitoring of
 faults in automatic transmissions. It is noted that in order to carry out active monitoring of automated mechanical and
 hydromechanical transmissions that have complex elements of gear interaction, it is necessary to obtain interdependencies
 between diagnostic parameters and criteria for assessing the technical condition in order to implement this information
 in monitoring and diagnostic algorithms for mobile applications.
