THE INFLUENCE OF THE OPERATIONAL PROPERTIES OF THE WORKING FLUID ON THE RELIABILITY OF HYDROMECHANICAL TRANSMISSIONS OF CARS

Аннотация

This article is devoted to the analysis of the influence of the operational properties of the hydraulic transmission fluid on reliability. Based on the analytical review and operational observations made by the authors of the article, it is recommended to introduce high-performance filters for cleaning the working fluid (oil) with a drop-out fineness of no more than 10 microns into the hydraulic system. Also recommended for hot climate conditions is the frequency of oil change, which should be 15-20% lower compared to non-hot climate conditions. KEYWORDS Hydromechanical transmission, viscosity, oil oxidation, friction force, additives, boundary layer.
