Compressed air suspension for buses and lorries

摘要

The compressed air suspension has two parabola-shaped sheets (2) of shallow curvature. It has two half leaf springs (1) and two compressed air pistons (6). The suspension system includes an overflow valve (10), a pressure reducing valve (9), two levelling valves (8), two upper and two lower holders for the pistons, two elastic attachments and two skids formed by elastic buffers. The two parabolic sheets are fitted to the axle of the vehicle on which the entire suspension, consisting of the above-named parts, is fitted.
