Device for reducing the impact energy of tire and rim fragments
This invention relates to a device for reducing the impact energy of tire and rim fragments, comprising a rim with pneumatic tire mounted thereto, whose cavity is filled with a gas volume, wherein a displacer connected with the rim is arranged inside the tire cavity, and the displacer does not come into contact with the tire.
1 . A device for reducing an impact energy of tire and rim fragments, the device comprising:
a rim with a pneumatic tire mounted thereto;
wherein the pneumatic tire has a cavity which is filled with a gas volume;
a displacer connected to the rim; wherein the displacer is arranged inside the tire cavity; and
wherein the displacer is adapted such that there is no contact to the tire.
2 . The device of claim 1 , wherein the displacer is dimensioned to take up the greatest possible share of the gas volume in the tire cavity and simultaneously essentially preclude contact between the displacer and the tire during operation of the device in vehicles.
3 . The device according to claims 1 or 2 , wherein the displacer occupies up to 90% of the gas volume in the tire, the gas volume being pressurized.
4 . The device of claim 1 , wherein the displacer is made of a material selected from the group consisting of a resilient material, a rigid material, an openly porous material and a closed porous material.
5 . The device of claim 1 , wherein the displacer and the rim are arranged as a single, integral component.
6 . The device of claim 1 , wherein the vehicle is an aircraft or a land vehicle.
7 . A method for reducing the impact energy of tire or rim fragments given a burst tire or rim failure comprising providing a displacer inside a tire cavity in a vehicle having a rim with a gas-filled tire mounted thereto.
8 . The method of claim 7 , wherein the vehicle wheel is an aircraft wheel or a land vehicle wheel.
9 . The method of claim 7 , wherein the displacer is connected to the rim without coming into contact with the gas-filled tire.
