  • Patent number: 11505221
    Abstract: A floating caliper brake device for a railroad vehicle includes: a support pin that is supported by a cylindrical portion of a support frame in such a manner as to be slidable in a direction X; a caliper; a first and second brake shoe; a pressurizing device that moves the first brake shoe back and forth; an elastic member that is expandable and contractible in the direction X; a stopper member that is immovable relatively to the cylindrical portion in the direction X; and a moving member that is frictionally engaged with the support pin so as to be slidable in the direction X.

  • Patent number: 10670094
    Abstract: A brake lining includes friction structures, back boards fastened to respective the friction structures, a base plate supporting the friction structures. Each of the friction structures includes two adjacent friction portions with a groove formed in the front surface in between, and a thin portion with a smaller thickness than thicknesses of the friction portions, the thin portion located in a position corresponding to the groove. Each of the friction structures is supported by the base plate on two support points located in the two friction portions respectively. The thin portion has a constant length, the length being equal to a maximum width of the friction portions and satisfying a condition that L/D is equal to or greater than 1.1, where D denotes the length of the thin portion and L denotes a distance between the two support points located in the friction portions.
