FIELD: railway transport. SUBSTANCE: suspension has rod 1 with shoulders 2 coupled at one side with bracket 3 of reduction gear 4 and at other side, through support plate 5 and flexible members 6, with cross beam 7 of bogie frame. To increase reliability and longevity by way of increasing resilience in direction of action of loads, composite ring 10 is installed on solid support plate 5. Outer conical surface of ring 10 mates with inner conical surface made in support plate 5, angle of cone being chosen within 30 and 45 degrees. Composite ring 10 has cylindrical projection at base of outer conical surface and cylindrical shoulder on support surface of ring 10. Cylindrical groove is made in support plate 5 at base of inner conical surface. EFFECT: increased reliability and longevity of suspension. 3 cl, 5 dwg
