Embodiment Construction

[0020] see Figure 4 ~ Figure 8 , the present invention comprises brake beam 5, lever 4 and down link 6, and fulcrum seat is installed on the bolster of bogie, and the fulcrum seat is connected with brake fulcrum, and the other end of brake fulcrum is connected with lever 4. The key technology is that the fulcrum seat includes a mounting plate 10 and a connecting plate 12 connected with the mounting plate 10, and a long hole 13 is opened on the connecting plate 12, and the braking fulcrum includes an ear plate 14 and a splint 11 connected with the ear plate 14. The plate 10 is installed on the bolster of the bogie, the ear plate 14 is connected with the connecting plate 12 through the elongated hole 13 , and the splint 11 is connected with the lever 4 .

[0021] The mounting plate 10 is mounted on the bolster of the bogie through rivets 16 or bolts.

[0022] A round hole 15 is opened on the lug plate 14, and the round hole 15 is connected with the elongated hole 13 through th...

Abstract

The invention relates to railway goods transporters, in particular to a bogie for a rail wagon. A lower pull rod type bogie braking fulcrum device comprises a braking beam, a lever and a lower pull rod. A fulcrum seat is installed on a swing bolster of the bogie. The lower pull rod type bogie braking fulcrum device is characterized in that the fulcrum seat comprises a mounting plate and a connecting plate connected with the mounting plate; a strip hole is formed in the connecting plate; a braking fulcrum comprises an ear plate and a clamping plate connected with the ear plate, wherein the mounting plate is installed on the swing bolster of the bogie, the ear plate is connected with the connecting plate through the strip hole, and the clamping plate is connected with the lever. The lower pull rod type bogie braking fulcrum device has the advantages that the strip hole is formed in the connecting plate of the fulcrum seat, the ear plate of the braking fulcrum penetrates through the strip hole through a pull rivet pin, as a result, the fulcrum seat and the braking fulcrum are flexibly connected, the braking fulcrum has the self-adaption property, the device can adapt to differences in empty and load deflection of the rail wagon, influence on a barding device by the differences in empty and load deflection of the rail wagon is reasonably eliminated, the misalignment phenomenon between braking devices of the bogie for the rail wagon can be remarkably reduced, and the problem that brake release of the rail wagon is poor is effectively solved.

Description

technical field [0001] The utility model relates to a pull rod type bogie braking fulcrum device, which relates to a railway cargo transportation device, in particular to a bogie used for railway freight cars. Background technique [0002] For traditional truck cast steel bogies, the brake fulcrum device of the foundation brake device is as follows: figure 1 or figure 2 As shown, it includes a brake beam 5, a lever 4, and a lower rod 6 or a middle rod 7. The fulcrum seat 1 is welded on the bolster of the bogie. Fulcrum, the other end of the braking fulcrum is connected with lever 4. Due to the large difference in the vertical loads of railway freight cars and empty vehicles, large vertical deflection displacements are generated, and because the fulcrum seat 1 and the five-eye iron 2 constitute a braking fulcrum device in the form of a rigid structure, it will cause the bolster connected to the bolster. The fulcrum seat and the fulcrum are not strong, and even other brake...
