PURPOSE:To improve durability, by providing a means for communicating fluid spring chambers on the right and left hands through a valve each other and closing the valve when an automobile travels at a speed greater than a set speed and a steering angle or acceleration in the right and left direction of the automobile is greater than a set value. CONSTITUTION:An acceleration sensor 39 senses acceleration in the right and left directions applied to a body and an automobile speed sensor 38 senses an automobile speed. Further, a steering sensor 41 senses a steering state of a steering wheel 42. When the sensor 41 or 39 senses a steering speed angle greater than a set value or acceleration greater than a set value in the case that the automobile speed sensed is grater than a set value, the communication of the air spring chamber 7 on the left suspension with the air spring chamber 7 on the right suspension is shut off. With this arrangement, a solenoid valve as a communicating means of the air spring chambers 7 is not forcibly energized continuously, whereby its durability can be improved. |
