US 2019/0063532 A1 · BRAKE SHOE ABRASION DETECTION UNIT OF RAILWAY VEHICLE, AND BRAKE SHOE ABRASION DETECTION UNIT SET

Abstract

There is provided a configuration that can precisely detect abrasion of brake shoes of a railway vehicle. A brake shoe abrasion detection unit includes: at least one abrasion detection RF tag that is attached at a position of an abrasion limit of a brake shoe of a railway vehicle tread brake or a position closer to a braking surface than the abrasion limit; and a reference RF tag that is attached at a position beyond the abrasion limit of the brake shoe.
