[0001] The utility model relates to the technical field of thermal stress elimination, in particular to an aircraft tire thermal stress elimination device. Background Art

[0002] Thermal stress is the stress generated when an object's temperature changes, due to external constraints and the mutual constraints between its internal parts, preventing it from fully expanding or contracting. This stress is also known as variable temperature stress or temperature stress. To improve the safety of aircraft tires during use, it is necessary to eliminate this thermal stress.

[0003] In the existing thermal stress elimination technology, for example, the existing technology with application number CN202310281568.4 includes a movable guide rail mounting plate, a first movable guide rail, a second movable guide rail, a pressure plate, an oil cylinder, a transition plate, a piston, an expansion tube, a fixing rod, an L-shaped pressure plate, a fixed guide rail and a magnetic iron, etc. The thermal stress causes the α angle between the movable guide rail panel and the transition plate to automatically return to zero.
