FIELD: transport.
SUBSTANCE: invention relates to active vibration insulators used in whatever machinery. Proposed drive comprises active sections arranged inside housing and representing piezo elements coupled with drive rod. Housing consists of coaxial blank cylinders, inner one being furnished with shoulder on outer end and outer one axially displacing. Rod inner end has end and intermediate shoulders interacting with inner and outer cylinder surfaces. Active sections representing annular piezo elements are arranged between end shoulder surface and inner cylinder shoulder.
EFFECT: reduced sizes, increased amplitude of its displacement.
