ABSTRACT:
An air suspension comprises a shock absorber having a piston rod in which is disposed a control rod for adjusting a damping force, 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 having a rigid member to which the piston rod is fixed and in which the valve body is disposed and connected to a car body and an actuator provided above the support to adjust at the same time the damping force of the shock absorber and the spring constant of the air spring. The actuator is provided with an electric motor, a gear fixed to the motor and a pair of rods arranged parallel to each other and extended toward the rigid member of the support, one rod being coupled with the control rod and the other being coupled with the valve body. The pair of rods are coupled respectively with a pair of tubes supported rotatably by a bracket through pins. A gear is fixed to each tube and at least one of two gears meshes with the gear of the motor.
