Title:
摩擦緩和材の収容装置及び摩擦緩和装置
Document Type and Number:
Japanese Patent JP4291088
Kind Code:
B2
Abstract:
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.
The storage device 9 stores the friction relaxation material C1containing a carbon based material as a main component and the storage device 10 stores a thickener C2comprising a ceramic particle for increasing friction coefficient. When the vehicle passes through a sharp curved line, the friction relaxation material C1flows 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 C1having 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 C1and is recovered in a lower storage part.
