|発明の名称||FRICTION RELAXATION MATERIAL, ITS STORAGE DEVICE AND FRICTION RELAXATION DEVICE|
PROBLEM TO BE SOLVED: To provide a friction relaxation material, its storage device and a friction relaxation device capable of relaxing friction resistance between a rail and a wheel by an inexpensive material and stabilizing quality.
SOLUTION: The storage device 9 stores the friction relaxation material C1 containing a carbon based material as a main component and the storage device 10 stores a thickener C2 comprising a ceramic particle for increasing friction coefficient. When the vehicle passes through a sharp curved line, the friction relaxation material C1 flows from a conduit 11a to a conduit 14 with compression gas and is injected from an injection port 15. As a result, friction resistance between a head apex surface 1c of the rail 1a and a step surface 4c of the wheel 4a is relaxed and lateral pressure generated between the rail 1a and the wheel 4a is reduced. The fine powder of the friction relaxation material C1 having a particle diameter smaller than a predetermined value is passed through a mesh part in the storage device 9 and is dropped off to a lower side, and is removed from the friction relaxation material C1 and is recovered in a lower storage part.
