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.
