ADJUSTABLE SHOCK ABSORBER Russian patent published in 2005 - IPC

FIELD: transport engineering; vehicle suspensions.

SUBSTANCE: proposed adjustable shock absorber contains piston with double-acting pressure transducer and step electric motor whose armature is stationary secured on rod and inductor is furnished with cover with projecting ring lugs with holes made in lugs. Transducer generates electric signal proportional to speed of piston displacement. Signal is transmitted to control device which generates required number of pulses and conveys them into armature winding of step electric motor. Inductor with cover is turned through angle providing change of passage area of channels in piston to value creating resistance with force which is regulated by program of realized resistance characteristics for specific stroke and speed of displacement of piston.

EFFECT: dispensing with elastic valve members in shock absorbers, enlarged range of resistance characteristic control.
