SU145901A1 - Eight-axle railway gondola - Google Patents

Description

The eight-axle railway gondola cars with two four-axle bogies, a body and unloading hatches are known. Each four-axle bogie consists of two biaxial jointed beam. The described gondola is distinguished from the known ones in that the connecting beam of the carriages has bevels at the ends in the places under the wagon beam. The proposed design change ensures the passage of the car through the humps and on the curves of small radius. In addition, in order to increase the strength of the body, the upper wrap of the car is made of a semi-closed profile, locked in a box section, and to save the hatch covers from damage, the supporting surface of the transverse beams of the car frame is located above the surface of the hatches. The closing mechanism of the manhole covers is a system of two pivotally connected levers, of which one is pivotally fixed on the manhole cover and the other rigidly on the shaft located along the ridge beam. This mechanism makes it easier to close manhole covers.

FIG. 1 shows an eight-axle gondola car in two projections; in fig. 2 - four-axle trolley in two projections.

The eight-axle railway gondola has a frame D side walls 2, front double doors 3, two four-axle bogies 4 and unloading hatches 5. The gondola is equipped with a reinforced automatic coupling 6, an automatic brake 7 and a hundred-night brake 8 with a quick release. The four-axle bogie includes two biaxial bogies. I am connected by beam 10, which has a reduced bog 11

No. 145901- 2 ends of the beam 10 has bevels 12, providing the oscillation of the trolley under the stern beam of the gondola. Racks 13 of the body are made of closed profiles of the cross-sectional height of the section, which ensures rational use of the metal. To more fully utilize the size of the rolling stock, one part of the uprights is located inside the car and the other part is outside.

The location of the unloading hatches in the floor facilitates the conditions for unloading bulk cargo, and the folding front doors create better conditions for loading and unloading self-propelled, long-length cargo and containers.

The use of the proposed eight-axle cars can reduce the cost of transportation.

Subject invention

Claims (4)

1. An eight-axle railway gondola with two four-axle bogies, each of which consists of two two-axle bogies, connected by a connecting beam, a body of cold-bent profiles and unloading hatches, characterized in that, in order to ensure the passage of the car through the humps and on small-radius curves, the connecting beam of the carts is made with bevels at the ends in the places under the ridge beam. 2. The carriage under item I, characterized in that, in order to increase the strength of the body, its upper cover is made of a semi-closed profile, periodically locked up with a box section. 3. The car on PP. 1 and 2, characterized in that, in order to preserve the hatch covers from damage, the transverse beams of the car frame have a supporting surface located above the surface of the latter. 4. The car on PP. 1-3, characterized in that, in order to facilitate the closing of the hatch covers, the closing mechanism of the latter is made in the form of a system of two pivotally connected levers, one of which is hingedly mounted on the hatch cover and the other rigidly on the shaft located along the ridge beam.
