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

FIELD: transport.

SUBSTANCE: invention relates to machine building. Suspension comprises main flexible element 2 and additional flexible element fitted inside the former and aligned with it, additional flexible element representing hollow plunger 4 divided by piston 5 into two spaces. Rod 6 is fitted in cover 3 of main flexible element 2. Plunger bottom space is communicated via channel 7 and gas feed electrically driven air valve 8 with receiver 9 at the start of every compression stroke and with atmosphere in rebound stroke. Plunger bottom space is communicated via channel 10 and gas feed electrically driven air valve 11 with receiver 9 at the start of every compression stroke and with atmosphere in rebound stroke. Rod 6 of piston 5 is made solid. Switching devices (12, 13) of electrically drive air valve (8, 11) are controlled by control unit (14) that comprises transducer (15) of main flexible element travel and is connected with relative speed signal generator (16).

EFFECT: higher efficiency of damping.
