Bondarenko A. Improvement of processes of modulation pressure in a pneumatic brake drive of cars

The research object is transients in the pneumatic brake drive of car with ABS. A research purpose is diminishing of expense of working body due to the improvement of processes of modulation of pressure in the pneumatic brake drive of cars. The research subject are conformities to the law of influence of communicating sections of keyer of pressure on the expense of supplies of the compressed air and adjusting quality. The theoretical (mathematical design, decisions of equalizations and their analysis) and experimental (model tests of object) methods of researches are utilized. Scientific novelty: the quantitative estimation of influence of communicating sections of keyer of pressure on the expense of supplies of the compressed air is first executed at latitudinal-impulsive modulation; optimizations of communicating sections of keyer of pressure with variable communicating sections and coefficients of trial influence and sensitiveness are executed; developed recommendation on forming of pulsating signal at braking of vehicle with a pneumatic brake drive (ABS is equipped with latitudinal-impulsive modulation) for the increase of brake efficiency, divisibility and stability of car. Got subsequent development of determination of influence of layout and construction of keyer of pressure in a time of wearing-out of pneumatic brake drive chart and expense of supplies of the compressed air at latitudinal-impulsive modulation. Practical value: job performances are applied in DNVP of "Association Communard" at drafting of requirement specification for development of ABS for the truck of KRAZ. Sphere of the use: in organizations which are engaged in planning of new and lead through of modernization of existent ABS for cars with a pneumatic brake drive.
