Abstract
An air spring may include a first end member and a second end member spaced from each other; a flexible bellows having a first end portion airtightly coupled to the first end member, a second end portion airtightly coupled to the second end member, and a jacket mounted on the circumference of the flexible bellows and configured to support the flexible bellows.
Claims19
An air spring apparatus comprising:
- a first end member and a second end member spaced from each other;
- a flexible bellows having a first end portion airtightly coupled to the first end member, a second end portion airtightly coupled to the second end member, a fluid chamber formed in the flexible bellows, and a motion portion, wherein the flexible bellows disposed between the first end member and the second end member is extendable further than the second end member so that a length of the flexible bellows is longer than a distance between the first end member and the second end member, and is bent to the second end member to be coupled to the second end member to form the motion portion;
- and
- a jacket mounted on a circumference of the flexible bellows and configured to support the flexible bellows,
- wherein the flexible bellows includes:
- inner cords formed in the flexible bellows at a side of the fluid chamber;
- and
- external cords formed outward than the internal cords in the flexible bellows,
- wherein the internal cords and the external cord are aligned to extend in parallel to each other in the flexible bellows other than the motion portion, and
- wherein in the motion portion, the internal cords are aligned to obliquely extend a first direction and the external cords are aligned to obliquely extend in a second direction which is a direction opposite to the first direction.

An air spring apparatus comprising:
- a first end member and a second end member spaced from each other;
- a flexible bellows having a first end portion airtightly coupled to the first end member, a second end portion airtightly coupled to the second end member, a fluid chamber formed in the flexible bellows, and including a plurality of rubber layers and cords, wherein the flexible bellows includes:
- a first portion extending from the first end member and passing the second end member with a predetermined distance to be formed longer than a distance between the first end member and the second end member;
- a motion portion extending from the first portion in a first direction and being formed to change a direction thereof toward the second end member in a second direction;
- and
- a second portion extending from the motion portion in the second direction and coupled to the second end member;
- a jacket mounted on a circumference of the flexible bellows and configured to support the flexible bellows;
- a temperature sensor disposed adjacent to the motion portion;
- and
- a cold air supply unit configured to supply air to an interior of the jacket when a temperature measured by the temperature sensor is greater than a predetermined temperature.
