Abstract
A suspension for a vehicle comprises a shock absorber for damping vibration given from a wheel including a cylinder, a piston dividing the inside of the cylinder into two liquid chambers and a piston rod connected to the piston and having a bypass path for affording communication between two liquid chambers, a bushing interposed between the piston rod and a car body and having two fluid chambers spaced from each other axially of the piston rod and an air spring having two air chambers for damping the vibration given from the wheel in cooperation with the shock absorber. The damping force of the shock absorber, the spring constant and damping force of the bushing and the spring constant of the air spring can be adjusted by an actuator from the outside in three or two steps.
Claims15
