FIELD: transportation.
SUBSTANCE: invention relates to railway transport, particularly, to spring suspensions of freight car bogies. Suspension comprises cylindrical springs and resilient stroke limiters installed inside the springs. Limiters contain upper and lower end bases and elastic cylindrical rod. Height of the rod is selected from the condition of exceeding the height of the spring in a compressed state by 3–5 %. Full static deflection of the suspension before the limiter is activated does not exceed 0.97 of the full deflection of the springs. Outer diameter of the limiter is selected from the condition of providing a radial gap between the limiter and spring of 3–6 mm.
EFFECT: increased resource of spring suspension springs.
