Cheban A. Improved anti-lock system for vehicles of categories M3 and N3

Object of study - work process of the air break system with ABS of a vehicles. Subject of research - the influence of anti-lock system on the air flow from the supply of compressed air braking system, and ensuring the wheel rolling in braking performance with that prescribed. We used the analytic method of mathematical modeling and numerical methods for solving differential equations. Confirmation of theoretical concepts was carried out by experimental studies and factorial experiment. Scientific novelty lies in the fact that for the first time obtained a rational relationship between the characteristics of stepper motor and ABS modulator parameters of direct action. Further developed the study of pneumatic Brake with ABS, which allowed simulate the ABS modulator of direct action and to take into account the air flow from the culture of the pneumatic brake actuator. The practical significance of the study is that the developed method allows to determine the initial parameters of the electro-pneumatic modulator ABS direct action, which increases the effectiveness of the ABS method of calculating the air flow for a pneumatic brake actuator operates the ABS to determine the limit value for air flow, according to the requirements of the rules № 13 UNECE DSTU UN / ECE R 13-09:2002. Adopted for use at JSC "Volchanskiy aggregate plant", OJSC "Poltava Automobile Units Plant" and NPP "Elon-TT" technique used in the design pnevoaparativ. The practical use of the results aimed at achieving social effect and improve the working conditions of drivers, reducing the number of accidents and improve active safety of vehicles in general. Scope: enterprises that design and manufacture of braking systems for vehicles and units to them.
