Abstract

A device for preventing excessive increase of an internal pressure of a rolling assembly, the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, comprises a cold spot placed in the inner cavity of the rolling assembly for condensing vapor contained in a gas filled in the inner cavity.

Claims (32)

1. A system for preparing a rolling assembly before usage, the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, the system comprising:

a circulator for circulating a gas in the inner cavity;

a dryer for drying the gas to be circulated in the inner cavity;

an intake mean for introducing the gas to be circulated in the inner cavity; and

an exhaust mean for exhausting the gas circulated in the inner cavity and for guiding the gas exhausted to the circulator and to the dryer.

2. The system according to claim 1 , wherein the intake mean and the exhaust mean are placed coaxially, and

wherein the gas to be circulated in the inner cavity is introduced and is exhausted through a valve hole provided on the wheel.

3. The system according to claim 1 , wherein the wheel is provided with at least two valve holes, and

wherein the intake mean and the exhaust mean are connected to different valve holes.

4. The system according to claim 3 , wherein the system further comprises a connecting mean connecting the inner cavity of one rolling assembly and the inner cavity of another rolling assembly.

5. The system according to claim 1 , wherein the system further comprises a heating blanket wrapped around an outer circumference of the rolling assembly.

6. The system according to claim 1 , wherein the system further comprises a heating mean for heating the gas dried or the gas to be dried.

7. The system according to claim 1 , wherein the dryer is a heating oven capable of storing the rolling assembly inside of the dryer.

8. The system according to claim 1 , wherein at least one of the intake mean or the exhaust mean further comprises a tap for shutting the gas circulation off.

9. A method for preparing a rolling assembly before usage, the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, comprising:

a step for drying a gas to be circulated in the inner cavity;

a step for circulating, using a circulator, the gas after the gas is dried;

a step for introducing the gas to be circulated in the inner cavity;

a step for exhausting the gas introduced and circulated in the inner cavity; and a step for guiding the gas exhausted to the circulator and a mean for drying the gas.

10. The method according to claim 9 , wherein the method further comprises a step for heating an outer circumference of the rolling assembly.

11. The method according to claim 9 , wherein the method further comprises a step for heating the gas dried or the gas to be dried.

12. The method according to claim 9 , wherein the method further comprises a step for storing the rolling assembly inside of a heating oven.

13. A method for preparing at least two rolling assemblies simultaneously before usage, each the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, comprising:

a step for drying a gas to be circulated in the inner cavity;

a step for circulating, using a circulator, the gas after the gas is dried;

a step for introducing the gas to be circulated in the inner cavity of one rolling assembly;

a step for circulating the gas circulated in one rolling assembly to another rolling assembly;

a step for exhausting the gas introduced and circulated in the inner cavities of the at least two rolling assemblies; and

a step for guiding the gas exhausted to the circulator and a mean for drying the gas.

14. The method according to claim 13 , wherein the method further comprises a step for heating an outer circumference of the rolling assembly.

15. The method according to claim 13 , wherein the method further comprises a step for heating the gas dried or the gas to be dried.

16. The method according to claim 13 , wherein the method further comprises a step for storing the rolling assembly inside of a heating oven.
