するエアサスペンシヨンの車高調整機構。[Scope of Claim for Utility Model Registration] (1) In an air suspension in which gas is sealed together with hydraulic oil, a large-diameter piston case is provided at the upper end of the inner tube of this suspension, and a free piston is mounted within this piston case. The free piston is slidably fitted to define a large-diameter gas chamber and an independent oil chamber, and the large-diameter gas chamber is communicated with the gas chamber at the upper part of the inner tube through a through hole formed in the shaft of the free piston. Furthermore, a vehicle height detection means for detecting vehicle height, a hydraulic circuit for supplying and recovering hydraulic oil to the independent oil chamber, and a vehicle height control circuit for controlling the hydraulic circuit based on the detection result of the vehicle height detection means. An air suspension vehicle height adjustment mechanism characterized by the following: (2) In an air suspension in which gas is sealed together with hydraulic oil, a piston case is provided on the outside of the outer tube of this suspension, and a free piston is slidably fitted into this piston case, making it independent from the communicating oil chamber. an oil chamber, the communicating oil chamber communicates with the suspension internal oil chamber, further comprising a vehicle height detection means for detecting vehicle height, and a hydraulic circuit for supplying and recovering hydraulic oil to and from the independent oil chamber. ,
A vehicle height adjustment mechanism for an air suspension, comprising a vehicle height control circuit that controls a hydraulic circuit based on the detection result of the vehicle height detection means.
