項に記載のエアサスペンシヨン装置。[Claims for Utility Model Registration] (1) It has a main air chamber, a sub-air chamber, and a control valve for changing the state of communication between the main and sub-air chambers, according to the state of the control valve. An air suspension device configured to change an effective spring constant by changing the effective spring constant, wherein the control valve includes a pair of cylindrical bodies that are coaxial with each other and that slide airtightly into each other, and a member that is outside the cylindrical body. an engaging portion formed in the cylindrical body, an adjusting drive means having an output shaft perpendicular to the axial direction of the cylindrical body, and an adjusting drive means provided at an eccentric position of the output shaft and adapted to engage with the engaging portion. It has a corresponding engagement part,
An air suspension device characterized in that the state of communication between the main and sub air chambers is changed by selectively aligning ports provided in both the cylindrical bodies. (2) A utility model characterized in that the engaging portion comprises a slot provided on the outside of the cylindrical body, and the corresponding engaging portion comprises an eccentric pin protruding from the output shaft in the axial direction. Scope of registration claims 1st
The air suspension device described in section.
