Abstract

Inventia se refera la un dispozitiv pentru verificarea patinelor electromagnetice de franâ pe sina, care sunt utilizate frecvent în transportul electric urban pentru frânarea tramvaielor. Dispozitivul, conform inventiei, este constituit dintr-o sina de proba sectionata longitudinal în doua parti si anume o parte superioara ca o ciuperca pe care se aseaza o patina de verificat si o parte inferioara talpa, articulata la un capat cu un bolt astfel, încât este posibila departarea lor manuala cu ajutorul unui mâner pentru a se putea masura coeficientul de frecare cu ajutorul unei rigle gradate fixate pe talpa sinei si a unui reper montat pe ciuperca sinei, pe care este fixat, totodata, un mecanism cu surub actionat de o manivela care tensioneaza un dinamometru sustinut în doua suporturi care prin intermediul unui taler prevazut cu o garnitura elastica actioneaza orizontal asupra patinei de proba alimentata de la o sursa de tensiune constanta, cu o forta care sa nu permita alunecarea patinei stabilind astfel forta de frecare pe sina.The invention relates to a device for checking electromagnetic rail friction on the track, which are frequently used in urban electric transport for tram braking. According to the invention, the device comprises a sample track longitudinally sectioned in two parts, namely a top as a fungus on which a test pad is placed and a bottom sole, articulated at one end with a bolt such that it is possible to remove them manually by means of a handle to measure the coefficient of friction by means of a graduated gauge fixed to the rack and a marker mounted on the rail of the rail, on which is also fastened a screw mechanism actuated by a crank which tensions a sustained dynamometer in two supports which, by means of a magazine provided with an elastic gasket, act horizontally on the test patch fed from a constant voltage source with a force that does not allow the skid to slip, thus stabilizing the friction force on the rail.
