Bicycle air spring

摘要

An air spring comprising a pressurized first chamber including a gas, a first piston adjacent the first chamber and configured to slideably move relative to the first chamber, pressurized second chamber adjacent the first piston and opposite the first chamber, the air spring configured such that the first piston moves towards the first chamber during compression of the air spring and the first piston moves away from the first chamber during extension of the air spring, wherein as said first piston moves towards the first chamber during compression of the air spring, said first piston pushes at least a portion of said gas within said first chamber in a direction opposite said first piston, a second piston configured to slideably move relative to the first chamber, a pressurized third chamber adjacent the second piston and opposite the first chamber.

主权项

1. An air spring comprising:
a first member and a second member, wherein the second member slideably moves relative to the first member when the air spring is compressed or extended; a pressurized first chamber including a gas, the first chamber located substantially within the first member; a first piston affixed to the second member and configured to slideably move relative to the first chamber; a pressurized second chamber adjacent the first piston and opposite the first chamber; wherein the first piston is configured to seal the first chamber from the second chamber; the air spring configured such that the first piston moves towards the first chamber during compression of the air spring and the first piston moves away from the first chamber during extension of the air spring, wherein as said first piston moves towards the first chamber during compression of the air spring, said first piston pushes at least a portion of said gas within said first chamber in a direction opposite said first piston; a second piston disposed within the first member and configured to slideably move relative to the first chamber; a third member disposed within the first member and positioned external to the second member, the third member comprising a pressurized third chamber adjacent the second piston; wherein the second piston is configured to seal the first chamber from the third chamber; and wherein the air spring is configured such that the at least a portion of the gas within the first chamber moved by the first piston in a direction opposite the first piston moves the second piston away from the first chamber when the pressure inside the first chamber is greater than the pressure inside the third chamber.
