車両の懸架装置。The axles of the front and rear wheels are suspended from the body frame via springs, and a hydraulic cylinder is interposed between the body frame and the suspension spring to form a bypass passage connecting the upper and lower oil chambers of the hydraulic cylinder. A throttle passage that provides resistance to the flow of oil and a switching valve that connects and shuts off the bypass passage are interposed in the middle of the oil chamber, while one of the oil chambers is connected to a reservoir tank, and the other is connected to a hydraulic source via a check valve. A suspension system for a large special vehicle such as a crane-car, characterized in that it is selectively connected to a reservoir tank via a switching valve.
