Example Embodiment

[0017] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0018] Such as figure 1 with figure 2 As shown, the railway eight-axle bathtub gondola of the present invention includes a bathtub-type car body 1, four side-bearing bogies 2 symmetrically arranged under the front and rear ends of the bathtub-type car body 1, and two sets of equal-load side bearing systems 10. The side-bearing bogie 2 is composed of a core beam 4, a side frame 5, a wheel set 6, an axle box spring suspension device 7, and a lower side bearing 8 on the side frame 5. The two ends of the core beam 4 of the side-bearing bogie 2 and the side frame 5 are connected in a horizontal plane by vertically installed elastic pins 9, such as image 3 Shown. A longitudinal bolster 3 is provided between the core beams 4 of the two side bearing type bogies 2 at one end of the bathtub-type car body 1, and the center of the longitudinal bolster 3 is pro...

Abstract

The invention discloses a railway eight-axis bathtub open wagon which comprises a bathtub-type wagon body, four side-bearing load-bearing bogies and two uniform load side-bearing systems, wherein the four side-bearing load-bearing bogies are symmetrically arranged below the front end and rear end of the bathtub-type wagon body; each side-bearing load-bearing bogie is composed of a center disk beam, a side frame, wheel pairs, an axle box spring hanging device and a lower side bearing positioned on the side frame; a longitudinal swing bolster is arranged between the center disk beams of two side-bearing load-bearing bogies on one end of the bathtub-type wagon body; the center of the longitudinal swing bolster is provided with a big center disk hole matched with a big center disk on the bathtub-type wagon body; two ends of the longitudinal swing bolster are provided with small center disk holes connected with the center disk beams of the two side-bearing load-bearing bogies; and each uniform load side-bearing system is provided with a uniform load side-bearing cylinder abutted with the lower side bearing. The railway eight-axis bathtub open wagon disclosed by the invention has the advantages of big vehicle volume, strong load bearing capability and high transportation efficiency, and can satisfy the requirement of the current railway truck for development of big axle weight.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a railway eight-axle bathtub gondola car. Background technique [0002] With the development of railway freight cars to heavy loads, the axle load and load of the vehicles continue to increase. At present, the width of the vehicle is restricted by the vehicle limit, and the length of the vehicle is restricted by the length of the dumper platform. Therefore, for vehicles with rated specific gravity (such as coal), the key to increasing the vehicle load and the weight per linear meter of the vehicle is to increase the vehicle load. volume. Increasing the vehicle volume becomes an important means to improve the vehicle transportation efficiency after the vehicle axle load increases (the axle load reaches 30t). [0003] Existing railway wagons are generally four-axle, and most of them are flat-bottomed gondola cars. In order to increase the volume of the vehicle, some gondola cars dedicate...
