The article discusses the sequence of assembly operations for some design options for limiting torque couplings, which are used to transfer torque M from the engine to the actuator until M does not exceed the limit value. In addition, the assembly sequence of various types of fl exible couplings is shown.

A digital equipment monitoring system has been developed and implemented, which includes dynamic recording of the number of wear products and oil temperature with original modern recording devices, followed by the technology of their processing and use. The system also includes methods for fi nding the necessary information in large data sets useful and necessary in theoretical and practical terms with a similar technique controlled by a digital monitoring system. The advantages of monitoring system are the ability to predict the reliability of the equipment; reduce production risks and significantly reduce inefficient costs.

The issues of the quality of assembly and repair of the vehicle on the basis of noise and energy characteristics are considered. The level of assembly and repair quality depends on the stability of the geometric dimensions and the material used, the constancy of allowances, the displacement of the centers of cylindrical parts and other defects; the possibility of performing some technological operations with one installation of the product; the distribution of the technological process into separate operations, ensuring approximately equal productivity on each of them; synchronization of technological operations The results of measurements of parts, the density of interfaces of internal combustion engine elements are presented. An estimated indicator of the quality of assembly and repair of the vehicle is given.

The tribo-induced effect of increasing the antifriction properties of lubricants with the combined use of cholesterol compounds and oil-soluble complexones is considered. It was found that the formation of boundary films is due to the following processes: the formation of complex compounds between ethanolamines and iron ions of the surface oxide film; removal of complexes from the friction surface; the interaction of the base of the lubricant with unoxidized iron; the formation of epitropic structured layers with cholesterol esters.

The PUMA lubricant with the use of additives has been investigated. The principle of their interaction with rubbing surfaces is analyzed in order to evaluate their effectiveness as antifriction agents and their infl uence on the structure of layers. The effect of an organophosphate and organosulfi de additive on surface wear compared. The infrared analysis revealed an increase in the concentration of iron in the spent lubricant and a decrease in the concentration of organic base oil in the system. The infl uence of functional groups and surface wettability on the formation of protective fi lms during friction, was revealed.
