A truck with an elastic frame of a freight car comprises a frame made of side frames rigidly interconnected in the track plane, a bolster, which rests by means of springs on axle boxes installed on the wheel pairs, while between the side frames of a trolley a cross link is mounted in the form of plates, whose opposite edges are rigidly attached to the side frames, and the section of plates is made in the form of a rectangle, whose larger side is directed along the longitudinal axis of symmetry of the trolley and the smaller one – along the perpendicular to the plane of the truck frame. |
