Air spring equipment is provided to extend an operation frequency range thereof by improving hardening of an air spring and rapidly falling of damping force. Air spring equipment includes an auxiliary air tank(2), a connecting pipe(3), and an orifice damper(4). The auxiliary air tank is connected to an air spring(1). The connecting pipe connects the auxiliary air tank and the air spring. The orifice damper is installed in the connecting pipe. The orifice damper has an orifice unit with an orifice hole and forward and reverse check valves formed at an outer peripheral part of the orifice unit. The forward check valve is composed of a first hole formed at one side of the outer peripheral part of the orifice unit and a first plate spring fixed to a front part of the orifice unit to elastically close the first hole. The reverse check valve is composed of a second hole formed at the other side of the outer peripheral part of the orifice unit and a second plate spring fixed to a rear part of the orifice unit to elastically close the second hole. |
