METHOD OF TESTING OF AUTOMATED BRAKES ON CARGO TRAINS AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2021 - IPC B60T17/22 

FIELD: railway transportation.

SUBSTANCE: invention relates to railway transportation, particularly a method of approbation of automated brakes on cargo trains which includes: a test of free passage of compressed air and of density of the brake main of the train, measurement of pressure in the brake main of the tail car, measurement of break release time of the two last cars after a brake step of 0.05 to 0.06 MPa and reception of information about the starting time of brake shoe retraction from the wheels on reposition of the brake valve into release position, wherein a controlled air release is conducted beforehand from the brake main at the speed of 0.01 MPa/min so that during brake system test the cargo train brake testing time is reduced compared to the regulation, and to an apparatus for implementation of the method, which consists of a body wherein in the top part of the body there is a hole with a flange, a barrel is installed into the hole resting on the flange of the end piece body, the bottom part of the barrel has a hole for free outlet of compressed air, a rod goes through the center of the top part of the barrel, a spring is sat at the top of the rod resting on the barrel and pressing into a shift knob, the bottom part of the rod is anchor-shaped, one of the blades pressing into the bottom part of the barrel, for germetization there are a sealing ring between the rod and the barrel and sealing between the flange of the barrel and the flange of the hole of the valve body.

EFFECT: reduced time for automated brake testing on cargo trains with high-density brake mains.
