Abstract
A wheel with a pneumatic tire, with the tire cavity divided into two fluid-filled reservoirs connected with a passageway (orifice, capillary, or porous material) having a required degree of flow restriction in order to generate a desired damping action when the tire is subjected to a vibratory exertion. The flow in the passageway is maintained at a laminar regime.
Claims13
In an inflated fluid-filled tire adapted to be supported on a vehicle wheel, of the type having a fluid-filled cavity connected with a separate fluid-filled chamber via energy-dissipating passageway,
- the improvement comprising:
- said fluid-filled damping chamber being disposed inside said fluid-filled tire cavity;
- and
- at least one energy-dissipating unrestricted elongated flow passageway connecting said fluid-filled tire cavity with said fluid-filled damping chamber.
In an inflated fluid tire on the vehicle wheel with fluid-filled cavity of said tire connected with a separate fluid damping chamber via energy-dissipating passageway,
- the improvement comprising:
- at least one fluid-filled damping chamber constructed inside said fluid-filled tire cavity thus partitioning said fluid-filled tire cavity into at least two fluid-filled reservoirs;
- and
- at least a part of the wall of said fluid-filled damping chamber separating it from said fluid-filled tire cavity made of a porous material providing calibrated restricted fluid flow between said fluid-filled tire cavity and said fluid-filled damping chamber.
In an inflated fluid tire on the vehicle wheel with fluid-filled cavity of said tire connected with a separate fluid chamber via energy-dissipating passageway,
- the improvement comprising:
- at least one fluid-filled damping chamber constructed inside said fluid-filled tire cavity thus partitioning said fluid-filled cavity into at least two fluid-filled reservoirs;
- at least one fluid-filled vessel supported on the wheel;
- said at least one fluid-filled damping chamber inside said fluid-filled cavity and said at least one fluid-filled vessel supported on the wheel connected by fluid flow passages having low flow resistance;
- and
- at least one energy-dissipating unrestricted elongated passageway connecting said fluid-filled tire cavity with said at least one fluid-filled damping chamber.
