Detailed Description
[ example 1 ]
As shown in fig. 1 and 2, the left hub 1 and the right hub 1 are sleeved (fixed by bolts after being sleeved, or directly connected by high-strength bolts without adopting a sleeving manner) to form a complete hub 1 (the left hub 1 or the right hub 1 is connected with a spoke, or the left hub 1 and the right hub 1 are connected with the spoke at the same time), and a hub clamping groove 2 is formed at the sleeved position.
When the hub 1 is combined with a tyre: the left wheel hub 1 and the right wheel hub 1 are respectively sleeved from the left side and the right side of the tire, when the left wheel hub 1 is combined with the right wheel hub 1, the middle surface enters the wheel hub clamping groove 2 (an observation hole can be formed in one side, close to the axle, of the wheel hub clamping groove 2, so that the middle surface can accurately enter the wheel hub clamping groove 2 and the installation in place can be confirmed). The middle surface is clamped by the hub clamping groove 2 while the left and right hubs 1 are fixed together (the shape of the cross section of the hub clamping groove 2 is not limited to the trapezoid shown in each figure, and can be other polygons or ellipses capable of clamping the middle surface). The middle surface is tightly combined with the hub clamping groove 2, and the left and right side surfaces 5 of the tire are respectively tightly combined with the left and right flanges of the hub 1 (the same principle as that of the common vacuum tire), so that the left and right cavities of the tire form a closed space (for simplifying the view, the hub flange is not shown in fig. 3, 5, 7, 9, 10 and 11). The outer openings of the valve nozzles of the left cavity and the right cavity are respectively arranged at any position of one side of the left hub 1 and the right hub 1 close to the axle (for convenience of inflation, a channel can be arranged on the hub 1 to lead the outer opening of the valve nozzle of the hub 1 at one side to the hub 1 at the other side). Examples 2, 3, 4, 5 and 6 are the same.
As shown in fig. 3 and 4, the middle surface clamped by the hub clamping groove 2 extends out of an annular plane 3 in the direction of the tread 6, the annular plane 3 extends out of a square wave annular curved surface 4 (as shown in the upper left drawing of fig. 8, the projection of the square wave annular curved surface 4 on the tread 6 is a square wave shaped curve, and the same applies to the following embodiments) in the direction of the tread 6 (the annular plane 3 is gradually stretched or gradually deformed into the wave shaped annular curved surface 4, or the annular plane 3 and the square wave annular curved surface 4 are connected through the middle surface, and the same applies to the following embodiments), and the square wave shaped annular curved surface 4 is connected with the inner side of the tread 6 and is not connected with the tire side surface 5. The annular plane 3, the square wave-shaped annular curved surface 4, the inner side of the tire tread 6, the left side surface 5 of the tire and the left hub 1 enclose a closed space (namely a left cavity), and the inner opening of the valve is arranged at any position (communicated with the left cavity) of the left hub 1 close to one side of the tire; the annular plane 3, the square wave-shaped annular curved surface 4, the inner side of the tire tread 6, the right side surface 5 of the tire and the right wheel hub 1 enclose another closed space (namely a right cavity), and the inner opening of the valve is arranged at any position (communicated with the right cavity) of the right wheel hub 1 close to one side of the tire; the left and right cavities are staggered with respect to each other (for the sake of easy viewing, the left and right lower views in fig. 3, 5, 7, 9, 10, 11 show the staggered left and right cavities separately as disassembled, and the middle plane of the upper right C-direction view in fig. 7, 11 clamped by the hub clamping groove 2 on the disassembled left and right cavities is segmented and shown as < actually connected same plane >).
When the cavity on one side of the tire leaks air, the cavity on the other side supports the tire under the action of air pressure, so that the condition that the tire is seriously deformed instantly to cause the vehicle to be out of control is prevented; the left cavity and the right cavity are mutually staggered at the parts close to the tire tread 6, and the non-air-leakage cavity can support the tire tread 6 of the component surface of the air-leakage cavity staggered between the left cavity and the right cavity while supporting the tire tread 6 of the component surface, so that the tire can keep a larger ground contact area. Examples 2, 3, 4 and 5 are the same.

In the embodiments, after one side or part of the cavity leaks air, the bearing capacity of the tire is lower than that of the tire in an unvulcanized state, so that the condition that the vehicle is out of control due to instant serious deformation of the tire can be prevented, and the vehicle is not suitable for running at high speed or for a long time. In order to prevent a driver from being unable to find out that the tire is air-leaked in time and continue to run at a high speed or for a long time, the tire pressure monitoring device can be additionally arranged, and a warning is sent to the driver when the air pressure of any side of the tire or part of the cavity is reduced.
In the above embodiments, the intermediate surface (including the intermediate surface when present) and the joint surface 7 may be separately manufactured and then subjected to the tire molding process together with other rubber components of the tire. The middle surface (including the middle surface when the middle surface exists) has the same strength as the tire side surface 5 (the strength can be properly reduced according to the requirements of lightening the tire weight and the like); the strength of the joint face 7 is lower than the strength of the middle face.
