Title: Variable damping type viscosity fluid damper
Inventor: JOJIMA HIROYUKI
IPC: F16F9/53
Filed: 1993-11-12
Abstract: PURPOSE:To control damping force by partitioning the inside of a damper in which liquid crystal is filled as viscosity fluid into upper and lower chambers by two electrode plates arranged at an interval, and drilling a hole in each electrode plate so as to form a passage between the upper and lower chambers. CONSTITUTION:An small interval is provided by means of an insulating spacer 4 on the center barrel part of the damper 1 of a hollow rubber shaped elastic body made of styrene TPE member and the like and two electrode plates 3a, 3b are arranged horizontally and in parallel oppositely to each other, the outside thereof is sealed by flanges 2a, 2b, and the inside of the damper 1 is partitioned into upper and lower chambers. Holes 8a, 8b are drilled in the electrode plates 3a, 3b in those positions shifted from each other, and liquid crystal 6 is sealed as viscosity fluid in the damper 1. Vibration is transferred to the upper part of the damper 1, and the liquid crystal 6 passes in a flow passage 7. At this time, since an electric field is generated in the flow passage 7 by the electrode plates 3a, 3b to which voltage is applied, viscosity of the liquid crystal 6 in the flow passage 7 is increased so as to change fluid resistance. The fluid resistance is thus varied, so that optimal vibration proof effect may be created optionally.
