Air suspension
This patent describes an air suspension comprising: a shock absorber having a piston rod in which a control rod for adjusting damping force is disposed; an air spring having a main air chamber and an auxiliary air chamber; a valve body for affording and shutting off communication between both air chambers to adjust the spring constant of the air spring; a support connected to a car body and including a rigid member with which the piston rod is coupled and in which the valve body is disposed and a bushing disposed diametrically outward of the rigid member and having a hole for an air passage between the air chambers which is controlled by the valve body; and an actuator disposed above the support to operate the control rod and valve body. The actuator comprises a rotary means, a pair of rods disposed parallel to each other and extended toward the rigid member of the support. One is connected to the control rod and the other connected to the valve body respectively. There is also a means for transmitting the turning force of the rotary to the pair of rods.
