Embodiment Construction

[0026] see Figure 2a with Figure 2b , Embodiment 1 of the present invention provides a column wear plate, which is used to be installed on the side frame of the bogie, specifically, installed on the bolster block of the side frame. The column wear plate 5 includes a groove bottom 51, and two groove sides 52 oppositely arranged on the groove bottom 51, the groove bottom 51 and the two groove sides 52 form a concave shape, and the concave shape is used to cover the bottom surface of the bolster block and sideways.

[0027] The shape of the bottom of the groove depends on the shape of the bottom surface of the bolster block. In the prior art, the bottom surface of the bolster block is generally rectangular, and the bottom of the groove is also rectangular. The two groove sides are relatively arranged on the two rectangular sides of the groove bottom, and the wear plate of the whole column is concave. The two groove sides can be arranged on the bottom of the groove symmetrica...

Abstract

The invention provides a column wearing plate, a steering frame and a railway truck. The column wearing plate comprises a trough bottom and two ledges oppositely arranged on the trough bottom, the trough bottom and the two ledges form a concave used for wrapping both the bottom surface and the side surface of a swing bolster shield, the ledges can be stopped on the side surface of the swing bolster shield to play the function of preventing the side surface of the swing bolster shield from being worn down, and in addition, the ledges can play a certain limiting role on the trough bottom after being arranged, so that the trough bottom has low probability of warpage or fracture, and the service life of the column wearing plate is prolonged.

Description

technical field [0001] The invention relates to technology, in particular to a column wear plate, a bogie and a railway freight car. Background technique [0002] Railway freight cars of wheel-rail vehicles are generally composed of car body, bogie, brake device, coupler buffer device and other parts. Among them, the function of the bogie is to support the car body, guide the vehicle to run along the track, and bear various loads from the car body and the line. Figure 1a A schematic diagram of the local structure of the bogie, Figure 1b for Figure 1a The most common bogie on a railway freight car is a cast steel three-piece two-axle bogie, which includes a bolster (not shown) and two side frames 1, and the raised part on the side frame 1 The bolster block 2 has a bottom surface 21 and a side surface 22 , and a flat rectangular column wear plate 3 is installed on the bottom surface 21 of the bolster block 2 . The side frame 1 and the bolster block 2 are integrally cast. ...
