Biaxial load carriage PLATE WITH RAMS

摘要

The invention relates to rail and touches the design tandem axle freight wagon. The proposed utility model reduces the stress state of the side frame carts and increase design reliability. To achieve said technical result in the construction of the bogie frame is inserted with a frame beam stops, interacting with the lower belt side frame so as to limit the amount of possible deflection of the beam axis from the frame perpendicularly to the longitudinal axis of the side frame. This in turn limits the possible magnitude of the relative displacement of the side frames in the direction along the railway. The position stops (gaps between the stops and the bottom chord side frame) is selected so that the amount of relative displacement of the side frames excludes the possibility of jamming the journal box of the wheel pairs in the pedestal opening side of the frame, which, in turn, eliminates the possibility of additional stresses in the inner corner pedestal opening, leading to destruction of the side frames, and thus increases the reliability of the cart.
