Abstract

Invenţia se referă la un arc de fricţiune, inelar, care se utilizează pentru amortizare, de exemplu, la vehicule feroviare. Arcul inelar, conorm invenţiei, are în alcătuire, la interiorul inelului exterior despicat (1), două sau mai multe grupuri de inele interioare despicate (2, 3, 4 şi 5, 6 7 şi 8, 9, 10 şi 11, 12, 13), cu secţiune constantă în formă de V, cu suprafeţe de contact conjugate sub un unghi (alfa) prestabilit şi ale căror fante (a, b, c şi d, e, f) sunt decalate între ele cu un unghi (gama) cuprins între 0 -şi180°, prestabilit la montare. Într-o altă variantă constructivă, suprafaţa de contact dintre inelele interioare despicate (5, 6, 7 şi 11, 12, 13) este în formă de "V" multiplu, ce are un unghi (beta) prestabilit. Într-o a treia variantă constructivă, suprafaţa de contact dintre inelele despicate (2, 3, 4 şi 5, 6, 7 şi 8, 9, 10 şi 11, 12, 13) este de formă curbă. Într-o a patra variantă constructivă, grosimea inelelor interioare despicate (2, 3, 4 sau 5, 6, 7 sau 8, 9, 10 sau 11, 12, 13) este varibilă în lungul circumferinţei.The invention relates to an annular friction spring which is used for damping, for example, on railway vehicles. The annular arch according to the invention comprises two or more groups of split inner rings (2, 3, 4, 5, 6, 7, 8, 9, 10 and 11, 12, 13) with a constant V-shaped section with conjugated contact surfaces at a predetermined angle (alpha) and whose slots (a, b, c and d, e, f) are offset with an angle (gamma) between 0 and 180 °, preset at installation. In another embodiment, the contact surface of the split inner rings (5, 6, 7 and 11, 12, 13) is in a multiple "V" shape having a predetermined angle (beta). In a third constructional variant, the contact surface between the split rings (2, 3, 4 and 5, 6, 7 and 8, 9, 10 and 11, 12, 13) is curved. In a fourth embodiment, the thickness of the split inner rings (2, 3, 4 or 5, 6, 7 or 8, 9, 10 or 11, 12, 13) is varied across the circumference.
