Abstract
A liquid-filled suspension device having an inner cylinder, an outer cylinder, and an elastic member connecting these cylinders to each other. A connecting member is arranged on the cylinder, a closed liquid chamber formed inside at least one of the inner and outer cylinders, a restricted passage formed in the middle portion of the closed liquid chamber, and a flexible membrane member arranged in the closed liquid chamber. An electroviscous liquid is filled in the closed liquid chamber, and two electrode plates arranged in the restricted passage. In this suspension device is used a control device having sensors arranged on these cylinders, and arithmetic decision logic operated by signals from these sensors, and a high-voltage generating circuit operated by signal from the arithmetic decision logic.
