PNEUMATIC SHOCK ABSORBER Russian patent published in 2011 - IPC F16F9/04 B60G13/14 F16F6/00 F16F15/03 

FIELD: machine building.

SUBSTANCE: pneumatic shock absorber consists of sleeve (1) and puncheon (2) interconnected with elastic element (3). An electro-magnetic oscillating drive is installed inside puncheon (2). The drive consists of asynchronous electric engine (4) with rotor (5) and a stator, of transfer element with rim (6) mounted on fulcrum pin (9). Rotor (5) is rigidly connected with the transfer element, while rim (6) is rigidly coupled with rod (7). Rod (7) is rigidly tied with ferrule (1). Coils (8) are positioned on rotor (5). Facing each other surfaces of rotor (5) and stator (4) are made as cylinder sectors. Rotor (5) is placed beyond plane of transfer element rolling. Stator coils of electric engine (4) are connected to control unit (11).

EFFECT: raised efficiency of oscillation damping.
