Abstract
Within the framework of the state program of import substitution of the Russian Federation, the design of an automatic gearbox and electronic electromagnetic control of the overrunning gear clutch has been developed. The theoretical justification of the coupling operation and the results of bench tests using methods of dynamic monitoring and tribospectral identification of friction processes in heavily loaded friction units are presented. It is proved that the transient characteristic of the overrunning clutch has the required quality ratings – the period of regulation tp and over–regulation σ, and the frequency characteristics correspond to the aperiodic link when it is turned on and the oscillatory one when it is turned off. The design of the automatic gearbox eliminates the phenomenon of interruption of the transmitted power flow and has high reliability indicators.
