BRAKING DEVICE Russian patent published in 2011 - IPC B61K7/02 B61H7/12 

FIELD: transport.

SUBSTANCE: invention relates to machine building, particularly to brakes of structures running on rails in antifriction bearings. Proposed braking device comprises show embracing rail head to move there along, shoe having its front part provided with wedge-like recess, and wedge made from elastoplastic material with surface coated by antifriction composition. Wedge and insert are secured, inside the show at the inlet of wedge-like recess with a gap relative to rail head, by means of locking elements sheared at preset force exceeding that of inertia acting on said elements in motion. Shoe walls have through opposed slots. Aforesaid insert incorporates at least two blades extending from said through slots to move there along in interacting with blocks made form low-density material and attached nearby rail in symmetry about each other at the point of braking start.

EFFECT: jogless braking of rocket train burnt-out stage, reduced costs on experiments with rocket trains.
