DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] as shown in FIG. 1, a foam filled wheel of the present invention 100 comprises: a steel ring 1, connecting a power device of a car (not shown) and having a filling mouth 11 with a filling mouth check valve 12 inside; a tire 2, set outside around the steel ring 1; and filling materials 5 disposed between the steel ring 1 and the tire 2 through the filling mouth 11 of the steel ring 1; it is characterized in that: the filling materials 5 are foaming materials, disposed between the steel ring 1 and the tire 2 through the filling mouth 11 of the steel ring 1. Thereby, the tire will not leak, thence it is achieved that the tire can support the car steadily even in case of damage.

[0030] In the present invention conventional steel ring and tire are used, wherein conventional filling gas is replaced by foaming materials, injected into the tire 2; whereby disadvantages of leaking, puncture in conventional air filled car wheel are avoided. Thence it is achieved that safety is increased.

[0031] Therein, the tire has an inner tire body (not shown) and the filling materials 5 are filled in the said inner tire body.

[0032] Filling materials 5 are foaming polymer materials of low specific gravity, which after solidification become a resilient solid, and comprise: 518 weight % of foaming agents (like HFC-245; 1.1.1.3.3-pentafluoropropane, 925 weight % of antioxidants (likeBHT), 3060 weight of foam stabilizers (like Tegostab B8462) and 2025 weight % of catalysts (like Dabco TMR-4). Since filling materials 5 in the tire 2 are foaming materials, the tire will not leak, thence it is achieved that the tire can support the car steadily even in case of damage.

[0033] Besides, since filling materials 5 in the tire 2 are foaming materials, so the tire cannot leak, is free from hot up and down due to temperature change. Thence, tire pressure is kept stable, and it is achieved, that life of a tire is extended.

[0034] As shown in FIG. 27, the manufacturing method of a foam filled wheel in the present invention comprises the following steps: a. as shown in FIG. 3, taking a steel ring 1 having a filling mouth 11, and a tire 2, set outside around the steel ring 1; b. as shown in FIG. 4, filling materials 5 of foaming materials are injected between the steel ring 1 and the tire 2 through the filling mouth 11 of the steel ring 1; c. as shown in FIG. 5, the filling materials 5 foam and flow into bottom of the tire 2 at the same time; d. as shown in FIG. 6, the tire 2 is filled with the filling materials 5 through the bottom of the tire 2, meanwhile gas in the inner tire 2 is discharged from the filling mouth 11 of the steel ring 1; e. covering the filling mouth check valve after destined time; f. as shown in FIG. 7, space between the steel ring 1 and the tire 2 is filled, after finishing foaming process of the filling materials 5; through the steps mentioned above, the tire will not leak, and it is achieved that the tire can support the car steadily even in case of damage.

[0035] As shown in FIG. 4, as processing the step b, firstly, setting the filling mouth 11 of the steel ring 1 upwards, then injecting the filling materials 5 of foaming materials between the steel ring 1 and the tire 2 through the filling mouth 11 of the steel ring 1, whereby it is easily to export gas in the inner tire thereafter.

[0036] As shown in FIG. 2, after the step 2 firstly processing: b1. after the filling materials 5 are disposed between the steel ring 1 and the tire 2 through the filling mouth 11 of the steel ring 1, injecting destined amount of gas, to avoid the filling materials 5 clogging the filling mouth 11 of the steel ring 1; then processing the step c.

[0037] As shown in FIG. 6A, the destined time of the step e is the same time, as the filling materials 5 process foaming into covering the filling mouth 11 of the steel ring 1. Therein, an operator can cover a filling mouth check valve (not shown), as filling materials 5 emerge at the filling mouth 11 of the steel ring 1.

[0038] As shown in FIG. 3A, outside around the steel ring 1 is further coated with release agent 13, whereby the finish foamed filling materials in the inner tire 2 cannot stick on the steel ring 1. Thence it is achieved, to change tires easily.

[0039] As shown in FIG. 2, after the step a processing firstly: a1. as shown in FIG. 3A, setting the filling mouth 11 of the steel ring 1 upwards and injecting release agent 13 through the filling mouth 11 of the steel ring 1, coating the steel ring outside around with the release agent 13, meanwhile, shaking the tire for increasing the coating area of release agent 13 outside the steel ring. Thereby in application of the present invention to a conventional air filled car wheel, costs for disassembling the tire are saved.

[0040] Therein, the release agent 13 is lipid or wax, which can avoid the filling materials 5 to stick on the steel ring.
