BRAKING DEVICE

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to test equipment. Braking device comprises shoe to embrace rail guide head and displace there along. Wedge-like recess with lead-in part oriented along motion direction is made inside said shoe, in front part of its top wall if sent in direction of motion of object to be braked. Wedge made from elastoplastic material and antifriction coat applied on its top surface enters said wedge-like recess in braking. Shoe top wall may remove wedge wear residues from surface of friction between shoe and rail head and wedge deformed section pushed through gap between shoe and rail head via through hole. Said through hole is made in shoe top wall behind wedge-like recess or via gap between shoe top wall face and sliding support. ^ EFFECT: reduced braking distance. ^ 7 cl, 4 dwg
