Abstract
The tire for a vehicle comprises a main body of the tire made from a rubber composite material and a rim to form a toroidal space therein, accommodates a toroidal pneumatic tube expandable due to its elasticity in the space for liquid, and the pneumatic tube has a smaller volume than that of a form obtained by depressing the space for liquid to a desired level by a road surface at the point of time when the tube is filled with air at a specified pressure required for supporting a load imposed on the tire, and the space for liquid in the depressed form which is outside of the tube is filled with liquid so that a desired ground contact area of the tire can be obtained under the load.
Claims7
A vehicle tire comprising a rim, a tire shell made of a rubber composite material and provided on said rim such that a toroidal liquid space formed in the tire shell is enclosed by the tire shell and the rim and a toroidal pneumatic air tube accommodated in the toroidal liquid space, said pneumatic air tube containing air and said toroidal liquid space containing a liquid for supporting a load imposed on the tire and obtaining a desired ground contact area of the tire, wherein said pneumatic air tube has a volume when it is filled with air at a specified pressure for supporting a specified load imposed on the tire which is less than the volume of said liquid space when said tire is depressed to a desired level by a road surface.
A vehicle tire comprising a rim, a tire shell provided on said rim such that a toroidal liquid space formed in the tire shell is enclosed by the tire shell and the rim and an elastically expandable toroidal membrane accommodated in the toroidal liquid space, the toroidal membrane having edges thereof airtightly connected to an inner peripheral wall of the tire such that a toroidal air space is formed between the membrane and the rim, said toroidal air space containing air and the toroidal liquid space containing a liquid for supporting a load imposed on the tire and obtaining a desired ground contact area of the tire, wherein said toroidal air space has a volume when it is filled with air at a specified pressure for supporting a specified load imposed on the tire which is less than the volume of said liquid space when said tire is depressed to a desired level by a road surface.
A vehicle tire comprising a rim, a tire shell provided on said rim such that a toroidal liquid space formed in the tire shell is enclosed by the tire shell and the rim and a toroidal membrane provided in the toroidal liquid space, the toroidal membrane having edges thereof airtightly connected to an inner peripheral wall of the tire adjacent to bead portions thereof such that a toroidal air space is formed between the membrane and the rim, said toroidal air space containing air and said toroidal liquid space containing a liquid for supporting a load imposed on the tire and obtaining a desired ground contact area of the tires, wherein said toroidal air space has a volume when it is filled with air at a specified pressure for supporting a specified load imposed on the tire which is less than the volume of said liquid space when said tire is depressed to a desired level by a road surface.
