Pimonov I. Increase in operational efficiency of hydro drives for construction and road machines by improving the onboard diagnostics.

Hydro drives of build machines. Perfection of the cushion diagnosing which allows to promote efficiency of exploita-tion of hydro drives of build and road machines. Substan-tive provisions of technical diagnostics and zakonі hydrau-lics. The cushion diagnosing of hydro drives of build ma-chines is developed by measuring of determining diagnostic parameter in one point; communication is set between the structural and diagnostic parameters of devices of hydro drives and the system of diagnostic parameters for the cushion diagnosing is certain; conformities to the law, de-termining forming of communication between the error of the cushion diagnosing of devices of hydro drive and their constituents in the case of vagueness of values of gaps in the devices of hydro drive, are first set. Decline of cost of diagnosing on 80...90% on comparison with a poagregatnim method at saving of necessary information about the technical being of gidroagregata; basic results of theoretical and eksperementalnih researches7.090214 "lifting-transport, build, road, meliorativnie machines andequipment" of the Kharkov national motor-car-road university are used in an educational process on speciality; introduction in the eksluatatsionnih terms of the cushion diagnosing from one point of gidroprivoda allows a pluchit annual economic effect on one machine 1000...1200grn. disertatsionnoy job performances are inculcated in "SUMR" Harkovspetsstroy DP.
