LOW-RESONANCE SHOCK ABSORBER Russian patent published in 2018 - IPC F16F1/04 F16F1/12 F16F3/02 

FIELD: machine building.

SUBSTANCE: invention relates to the field of mechanics, namely to shock absorbers. Low-resonance shock absorber comprises a body, an elastic spring-type element provided with a compensating static load node. Unit compensating the static load is made in the form of a pair of coil springs. Ends of the springs on one side are brought together, rigidly connected to each other and to the support element. Other ends of the coil springs are spread out and fixed to the corresponding spring pulley. Pulley is provided with a rotating shaft mounted in the shock absorber housing on the bearings. On one side of the housing, the bearing is fixed in a rotating bushing. Resilient element is a torsion spring coaxial with the axis of rotation of the pulley. One end of the spring is attached to the pulley, the other to the rotating bushing.

EFFECT: increase in the efficiency of preventing resonance modes of oscillation is achieved.
