Abstract

Prezenta inventie se refera la un arc de frictiune constituit dintr-o carcasa telescopica etansa în interiorul careia se afla o coloana de arc formata din inele interioare care conlucreaza cu niste inele exterioare prin intermediul unor suprafete conice de contact lubrifiate. Arcul de frictiune, conform inventiei, în scopul asigurarii unei cît mai bune ungeri a inelelor de arc în toate regimurile de solicitare si al prelungirii duratei de serviciu a arcului, prezinta o coloana de arc prevazuta în interiorul spatiului delimitat de suprafetele interioare ale unor inele interioare si exterioare cu o piesa tubulara constituita cu o coloana cilindrica dintr-un material deformabil elastic, ca de exemplu cauciuc expandat, cu un diametru mai mic exterior mai mic decît diametrul interior al inelelor interioare, în spatiul inelar creat între suprafata exterioara a coloanei cilindrice si suprafata interioara a inelelor interioare fiind introdusa o cantitate suplimentara de lubrifiant suficienta pentru toate conditiile mecanice sau termice de functionare a arcului.
