AUTOMOTIVE PNEUMATIC SUSPENSION

摘要

FIELD: transport.SUBSTANCE: invention relates to automotive industry. Pneumatic suspension comprises top piston and bottom cylindrical barrel, elastic element and damper. Said barrel and piston are made of rigid structural material. Barrel diameter exceeds that of piston. Said elastic element and damper are composed of cylindrical and elongated torus-shape shells with their chambers communicated with barrel air channels. Torus-shape shell envelopes piston end surfaces by internal unclosed surface. Piston end features surface hyperbolic shape with respect to piston vertical axis. Soft shells are filled with gas in working state. Constricted cross-section is composed of air channel in valve communicating said shells via air ducts. Gas is used as a working body of damper.EFFECT: decreased harmful effects on environments, simplified design.2 cl, 6 dwg
