Abstract

FIELD: mechanical engineering. SUBSTANCE: cooling system is mounted inside the pressure-tight sector space between ribs of the braking block. The system is made up as heat elements composed of two semiconducting rods of p- and n- type conductivities connected in parallel and series. The working surface of the braking drum and end faces of the semiconducting rods that are brought out to be installed flush with the friction linings are a hot junction. The free junction is formed by two other end faces of the semiconducting rods that are in a contact with separated arc-like plates mounted on an electrically insulating layer. A radiator is positioned from the back side of the layer. The inner surface of the space and two semiconducting rods in the body of the friction linings and base of the braking block are electrically insulated. EFFECT: enhanced efficiency of cooling. 2 cl, 2 dwg

Изобретение относится к машиностроению и может быть использовано в тяжело нагруженных барабанно-колодочных тормозах подъемно-транспортных, дорожных и строительных машинах. В настоящем техническом решении поставлена задача повышения эксплуатационных параметров барабанно-колодочного тормоза и ресурса его пар трения путем интенсификации их охлаждения. Для этого система охлаждения барабанно-колодочного тормоза, заключенная в герметизированную секторную полость между ребрами тормозной колодки (ТК), выполненная в виде термоэлементов, состоящих из двух полупроводниковых стержней (ПС) с проводимостями р-типа и n-типа, которые подключены между собой параллельно-последовательно. Горячим спаем в системе является рабочая поверхность тормозного барабана и торцы ПС, выведенные заподлицо фрикционных накладок. Свободный спай образован двумя другими торцами ПС, контактирующих с разделенными дугообразными пластинами, которые покоятся на электроизоляционном слое (ЭС). С обратной стороны последнего расположен радиатор, при этом внутренняя поверхность полости и двух ПС в теле ФН и основания ТК электроизолированы. Применение предложенного технического решения позволит увеличить количество отводимой теплоты от пар трения тормоза, так как с ростом температуры горячего спая двух ПС резко возрастает их удельная электрическая проводимость.The invention relates to mechanical engineering and can be used in heavily loaded drum-shoe brakes of hoisting-and-transport, road and construction vehicles. In this technical solution, the task is to increase the operational parameters of the drum-shoe brake and the resource of its friction pairs by intensifying their cooling. For this, the drum-shoe brake cooling system, enclosed in a sealed sector cavity between the edges of the brake shoes (TC), is made in the form of thermocouples consisting of two semiconductor rods (PS) with p-type and n-type conductivities that are connected in parallel -consecutively. A hot junction in the system is the working surface of the brake drum and the ends of the PS, brought flush with the friction linings. A free junction is formed by two other ends of the PS, in contact with divided arcuate plates, which rest on an electrical insulating layer (ES). The radiator is located on the reverse side of the latter, while the inner surface of the cavity and two PS in the body of the FC and the base of the TC are electrically insulated. Application of the proposed technical solution will increase the amount of heat removed from the friction pairs of the brake, since with increasing temperature of the hot junction of two substrates, their electrical conductivity sharply increases.
