Abstract
A vehicle suspension system has liquid pressure cylinder devices provided between the respective wheels and the vehicle body. Supply and discharge of hydraulic liquid to and from the liquid pressure cylinder devices is controlled according to the running condition of the vehicle. Each of the liquid pressure cylinder devices communicates with a pair of gas springs, each having a gas chamber and a liquid chamber parted from each other by a movable member. The liquid chamber communicates with the liquid pressure chamber of the liquid pressure cylinder device by way of a communicating passage, and the gas chamber is filled with gas. The initial pressure of one of the gas springs is higher than that of the other.
