Abstract
An air spring includes a first body; a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body; a pressurized second chamber; a flow passage between the first chamber and the second chamber; and a seal to selectively permit or restrict flow between the first chamber and the second chamber depending on a position of the first piston with respect to the first body.
Claims39
An air spring comprising:
- a first body;
- a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body;
- a pressurized second chamber;
- a flow passage between the first chamber and the second chamber;
- a seal to selectively permit or restrict flow between the first chamber and the second chamber;
- the air spring having a fully extended position and a fully compressed position, the air spring configured such that during the majority of the movement of the air spring from the fully extended position to the fully compressed position flow is permitted from the first chamber to the second chamber and while the air spring is adjacent the fully compressed position, the seal restricts flow between the first chamber and the second chamber.
An air spring comprising:
- a first body;
- a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body;
- a pressurized second chamber;
- a flow passage between the first chamber and the second chamber;
- a seal to selectively permit or restrict flow between the first chamber and the second chamber;
- wherein the compression of the air spring defines a spring curve, wherein the spring curve comprises a bump zone comprising the range of travel of the air spring between 30% compression and 70% compression of the air spring and the spring curve has a variation in the slope of the spring curve in the bump zone of not more than 20%.
