The article examines the dynamics of demand for innovative products in the pharmaceutical industry based on the logistics curve “S-shaped”. In the course of the research, the General mathematical model of logistic curvature, its geometric change and parameter estimation were considered. At the end of the work, an empirical equation of the demand curve was determined based on numerical values in various variants and the obtained scientific conclusions were generalized.

Subject of the inquiry: steering wheel of self-driven energetic vehicle means.
Aim of the inquiry: the aim of this inquiry is to rise the stability of the motion and conducting of self-driven means by rational choice of transmission ratio of the steering wheel.
Methods of inquiry : the analytical and experimental research methods are used in the work based on methods of automatic regulation theory.
The results achieved and their novelty: the character of the influence of the transmission ratio quantity on the sensitiveness of the machines the control and stability of the motion are used
The mathematical models for calculation of parameters of the motion of selfdriven energetic means with hydro-huged characters of the steering wheel and the choice of mounting coordinates of carried out hydrocylinders are worked out.
Practical value: the recommendations on the choice of transmission ratio of steering wheel and mounting coordinates of carried-out hydrocylinders rising stability of the motion and improving conduction of self-driven energetic means are worked out.
Mathematical models allowing to realize rational choice of parameters of steering wheel on the stage of project are created.
Degree of embed and economic effectiveness: recommendations on the choice of the quantity of transmission ratio of steering wheel and calculated definition of rational parameters of mounting hydrocylinders of the wheel implement are accepted for the usage in SSC (GAO) "Tashkent Tractor Plant".
Sphere of usage: tractor and agricultural machine-building.
