SEAT VIBRATION DAMPING SUSPENSION Russian patent published in 1999 - IPC

FIELD: mechanical engineering; protection of operator from vibration. SUBSTANCE: suspension features improved damping characteristics provided by introduction of special dampers into design of flexible hanger. Each damper consists of length of cable one end of which is hinge-secured on suspended support. Other end of cable can move in double-cone hole of carrying support. Lobe spring is secured on this end of cable. Lobes of spring are pressed to side surface of hole for flexible displacement together with end of cable in longitudinal and cross directions. Double-cone hole in carrying support is made in form of two truncated round cones connected through larger bases. This improves damping at heavy resonance vibrations of suspended support. Hinge mounting of damper cable suspended support reduces influence of elastic characteristics of damper cables onto rigidity of flexible hanger at displacement of suspended support relative to carrying support in horizontal direction. EFFECT: enhanced damping. 4 dwg
