Object of research: control procedure the pneumatic suspension at motion of the automobile. Purpose of research: perfecting of control procedure the pneumatic suspension. Method of research: the analysis of existing works on the pneumatic suspension and analysis of existing controlled systems is conducted, for research of influencing of a level regulator on service properties of the pneumatic suspension the method of mathematical modelling and numerical methods of the solution of differential equations was used, at definition of rational relation of the flow area of the regulator - graphical analytic method, at processing of outcomes of experimental researches - method of correlation analysis. Equipment: fixtures for static researches, control and measuring complex for road tests, computer equipment. Theoretical and practical outcomes: The mathematical model of the controlled pneumatic suspension is designed, which one resolves to allow for heat rejection through walls of pneumatic bellow, separationsof a wheel from a road and breakdowns of the suspension; the technique of definition of the area of bulkhead foramens is offered, which one resolves at the stage of designing to evaluate influencing the regulator on parameters of suspension oscillations and to determine rational relation of the flow area to a fleet angle of its lever. Scientific novelty: the rational relation of the area of flow areas of a level regulator is offered, the mathematical model of the controlled pneumatic suspension is advanced. Degree of application: is adopted in SI MDU "Kharkov automobile repair plant"; branch "Autocomponent" of joint stock company "Poltava autoaggregate plant"; joint stock company "Volchansk aggregate plant". Area of usage: automobile transport.
