Problems solved by technology

During the operation of the tank car on the line, due to the large torsional rigidity of the car body, the running quality of the tank car, especially in the empty state, on the curve is worse than that of the gondola car, box car, and flat car.

Embodiment Construction

[0022] see figure 1 — Figure 12 , the present invention includes a side bearing seat 1, a side bearing body 2 and a side bearing bottom plate 3. The key technology is: the side support seat 1 has a groove 1.3 that runs through to the bottom surface, the center of the side support base plate 3 is a boss 3.1 that matches the groove 1.3, the side support body 2 is located on the boss 3.1, the boss 3.1 and the side support The supporting body 2 is located in the groove 1.3 of the side bearing seat 1 . The side support seat 1 and the side support base plate 3 are connected by limit bolts 4, and there is a vertical gap of 2-5mm between the side support seat 1 and the side support base plate 3. The bottom of the limit bolt 4 is disc-shaped and has a groove, and the top has a pin hole, and the part where the screw rod is connected to the bottom of the bolt is the shoulder 4.1, so that the screw rod is stepped. The bottom of the side bearing base plate 3 is connected with an adjust...

Abstract

The utility model relates to an elastic upper and side bearing of a railway freight vehicle, which relates to a railway freight transportation device. It includes a side bearing seat, a side bearing body and a side bearing bottom plate. The key technology is: the side bearing seat has a groove running through to the bottom surface, the center of the side bearing bottom plate is a boss matching the groove, the side bearing body is located on the boss platform, and the boss and side bearing body are located on the side of the side bearing seat. inside the groove. Since the elastic rubber element is used in the upper side bearing, and the vertical displacement of the upper side bearing support surface is 2-5mm, the torsional deformation of the railway freight vehicle is increased, the torsional rigidity of the car body is reduced, and the vehicle is improved. running quality.

Description

(1) Technical field [0001] The utility model relates to an elastic upper and side bearing of a railway freight vehicle, which relates to a railway cargo transportation device, in particular to an elastic upper and side bearing used by a railway freight tank car. (2) Background technology [0002] At present, the railway freight tank cars in our country are all equipped with rigid upper side bearing devices, and the tank car bodies are mostly closed cylindrical structures. This structural feature determines that the torsional stiffness of the car bodies is greater than that of railway freight gondola cars, boxcars, and flat cars. . During the operation of the tank car on the line, due to the large torsional stiffness of the car body, the running quality of the tank car, especially in the empty state, on the curve is worse than that of the gondola car, box car, and flat car. (3) Contents of the invention [0003] The technical problem to be solved by the present invention i...
