SUSPENSION DEVICE

摘要

A suspension device from which problems involved in conventional dampers and rubber members are eliminated. A suspension device (101) is provided, for example, with a damper (50), a suspension spring (60), an upper seat (70), and a spring (1). The spring (1) is an elastic member disposed between the upper end of a piston section (51) and the lower surface of the upper seat (70) and is subjected to a load from the damper (50). Hysteresis does not occur in the load characteristics of the spring (1), and as a result, the dynamic spring constant of the spring (1) can be reduced. This can reduce the transmission of vibration in a high-frequency band and a small amplitude region. Also, in the spring (1), the body section (10) functions as a disc spring section. This increases the spring constant of the damper (50) in the vertical direction along the axis thereof to in turn increase the rigidity in the vertical direction along the axis. As a result, driving comfort can be improved and driving stability can be ensured.
