PNEUMATIC SUSPENSION Russian patent published in 2010 - IPC B60G11/27 F16F9/05 

FIELD: transport.

SUBSTANCE: invention relates to machine building. Proposed suspension comprises primary flexible element arranged between spring and no-spring parts that housed secondary flexible element aligned with it and made up of hollow plunger 4 divided by piston 5 into two chambers. Plunger rod end communicates with receiver 11 via air channel and electric air valve 10 controlled by speed pickup 13 and first switch 14 to feed gas at the start of each stroke and, to discharge the gas, with atmosphere. Plunger head end communicates via bore made in inner plunger bottom with atmosphere. Rod 6 of piston 5 is arranged in cover 3 of the primary flexible element. The bottom of plunger 4 accommodated electromagnetic device controlled by speed pickup 13 and second switch 17. Piston 5 makes the electromagnetic device armature.

EFFECT: higher damping efficiency in entire amplitude-frequency range of external effects.
