METHOD OF ATTACHMENT OF FITTINGS TO TUBE OF CONNECTING HOSE FOR ROLLING STOCK BRAKES AND CONNECTING HOSE Russian patent published in 2025 - IPC B60T17/04 

FIELD: railways.

SUBSTANCE: group of inventions relates to the field of railway transport, namely to a method of fixing fittings to a tube on a connecting hose and a connecting hose for rolling stock brakes. Method of attachment of fittings to tube on connecting hose for rolling stock brakes is carried out using clamps, which are installed on ends of tube at the location of the fittings, covering tube from outside. Clamp consists of a metal tape and a steel retainer made in the form of a single-slot buckle, wherein the steel strip of the clamp is installed on the tube at least in two envelopes and is attached to the buckle by bending so that the inner end of the strip is pressed to the tube for a length of at least half the length of the retainer, wherein tape length makes 2.2-3.2 of tube outer circumference, tape width makes 10-20 mm and tape thickness makes 0.5-1.2 mm. Connecting hose is made in the form of a tube, equipped on both ends with clamps installed on the ends of the tube in the place intended for the fittings, covering the tube from the outside, wherein the steel band of the clamp is installed on the tube in at least two envelopes and is attached to the buckle by a bend so that the inner end of the strip is pressed to the tube for a length of at least half the length of the retainer, wherein tape length makes 2.2-3.2 of tube outer circumference, tape width makes 10-20 mm and tape thickness makes 0.5-1.2 mm.

EFFECT: providing fast, reliable and safer fixation of fittings including a tip and a connecting head on a tube of a connecting hose for a rolling stock with simultaneous reduction of labour intensity of this process.
