FIELD: transport.
SUBSTANCE: group of inventions relates to road vehicle pneumatic suspension system. Pneumatic suspension system with pneumatic springs cylinders (3, 4), arranged on vehicle axis opposite sides, and using connecting pipelines (7, 8), in each case equipped with level control valve (5, 6), can be connected with main pressure pipeline (9) and cut off from it. Main pressure pipeline (9) by means of main discharge valve (10) can be alternatively connected with compressed air source (12) and compressed air receiver (11). Pneumatic springs cylinders (3, 4) connecting pipelines (7, 8) are connected to each other by means of connection pipeline (13), which is equipped with throttle (14) and can be cut off by shutoff valve. Shutoff valve (21) is made with possibility of mechanical control and connected that way with pneumatic spring cylinder (4) level control valve (6), which is located on vehicle side external relative to pavement, that shutoff valve (21) with closed level control valve (6) is open, and with open level control valve (6) is closed.
EFFECT: enabling possibility to adjust road clearance.
