| description | The invention relates to rail transport, specifically to brake shoes for freight rail vehicles, said brake shoes forming a friction pair with a tread of a rail wheel. The aim of the present invention consists in maintaining the desired operational characteristics of a shoe not only when used on a wheel not exhibiting tread wear, but also when used on wheels exhibiting tread wear close to a maximum permissible value. The aforementioned technical result is achieved by manufacturing a railway brake shoe comprising a metal frame and a composite polymeric friction element that is provided with a recess at its center on the same side as the working surface of the shoe, the depth of said recess being greater than half the thickness of the shoe. The shoe is made to be flexible in the area of the recess, which, under the operational forces of the brake shoe being pressed by means of a bracket to a wheel exhibiting tread wear close to a maximum permissible value, provides a mutual overlap coefficient of the brake shoe-wheel friction pairing that is from 0.08 to 0.12.
L'invention concerne le transport ferroviaire et notamment des mâchoires de frein de moyens de transport ferroviaires de marchandises, qui forment un couple de frottement avec la surface de roulement d'une roue de chemin de fer. L'invention vise à assurer des caractéristiques d'exploitation désirées d'une mâchoire non seulement lors du montage sur une roue sans usure mais aussi sur celles dont l'usure approche les valeurs limites admissibles. Ce résultat est obtenu par la fabrication d'une mâchoire de frein de moyen de transport ferroviaire, qui comprend une carcasse métallique et un élément de frottement composite polymérique au centre duquel on a réalisé, du côté de la surface de travail de la mâchoire, un renfoncement dont la profondeur représente plus de la moitié de l'épaisseur de la mâchoire. La mâchoire possède une flexibilité dans la zone du renfoncement qui assure, lors des efforts de fonctionnement, une compression par le sabot de la mâchoire contre une roue dont le kilométrage approche du maximum admissible, la valeur du chevauchement réciproque du couple de frottement mâchoire-roue allant de 0,08 à 0,12.

Изобретение относится к железнодорожному транспорту, а именно, к тормозным колодкам грузовых железнодорожных транспортных средств, образующим фрикционную пару с поверхностью катания железнодорожного колеса. Целью данного изобретения является обеспечение необходимых эксплуатационных характеристик колодки не только при установке на колесо без проката, но и на колеса, прокат которых близок к максимально допустимому значению. Указанный технический результат достигается изготовлением тормозной колодки железнодорожного транспортного средства, включающей металлический каркас и полимерный композиционный фрикционный элемент, в центре которого со стороны рабочей поверхности колодки выполнено углубление, глубина которого более половины толщины колодки. Колодка выполнена с гибкостью в зоне углубления, обеспечивающей при эксплуатационных усилиях прижатия башмаком колодки к колесу, имеющему прокат, близкий к максимально допустимому, величину коэффициента взаимного перекрытия пары трения колодка - колесо от 0,08 до 0,12.</description><language>eng ; fre ; rus</language><subject>ARRANGEMENTS OR DISPOSITIONS OF BRAKES OR OTHER RETARDINGAPPARATUS IN RAIL VEHICLES ; BLASTING ; BRAKES ; BRAKES OR OTHER RETARDING APPARATUS PECULIAR TO RAILVEHICLES ; CLUTCHES ; COUPLINGS FOR TRANSMITTING ROTATION ; ENGINEERING ELEMENTS AND UNITS ; GENERAL MEASURES FOR PRODUCING AND MAINTAINING EFFECTIVEFUNCTIONING OF MACHINES OR INSTALLATIONS ; HEATING ; LIGHTING ; MECHANICAL ENGINEERING ; PERFORMING OPERATIONS ; RAILWAYS ; THERMAL INSULATION IN GENERAL ; TRANSPORTING ; WEAPONS</subject><creationdate>2019</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20191205&DB=EPODOC&CC=WO&NR=2019231353A1$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76289</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20191205&DB=EPODOC&CC=WO&NR=2019231353A1$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>ROMANCHENKO, Vitaliy Valerievich</creatorcontrib><creatorcontrib>KUZMINYIKH, Andrey Germanovich</creatorcontrib><creatorcontrib>SUKHAREV, Evgeniy Albertovich</creatorcontrib><title>BRAKE SHOE FOR A RAIL VEHICLE</title><description>The invention relates to rail transport, specifically to brake shoes for freight rail vehicles, said brake shoes forming a friction pair with a tread of a rail wheel.
