Air spring type suspension

The invention refers to an air spring type suspension (30) including: a cylinder (32) including an air chamber (32a); an outer tube (34) surrounding the cylinder (32) and constituting a buffer chamber (34a) outside the cylinder (32), the buffer chamber (34a) connected to the air chamber (32a); a damper (36) capable of being inputted into and outputted from the air chamber (32a); a piston rod (38) in the air chamber (32a) and inserted into the damper (36); and an accumulator module (40) constituting a control chamber (40a) connected to the buffer chamber (34a), wherein a single closed space is constituted by the air chamber (32a), the buffer chamber (34a) and the control chamber (40a), and wherein a pressure change of the air chamber (32a) is induced by a pressure change of the control chamber (40a).
