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
A kind of drop-down rod-type bogie truck braking point device, relates to railway freight traffic device, the bogie truck that especially railway truck is used.
Background technology
Tradition lorry cast steel bogie, the braking point device of its foundation brake rigging as shown in Figure 1 or 2, comprise brake beam 5, lever 4 and lower link 6 or middle pull bar 7, on the bolster of bogie truck, weld fulcrum block 1, five eyebar 2 that connect rigid construction by round pin 3 on fulcrum block 1 are as braking fulcrum, and the braking fulcrum other end is connected with lever 4.Because railway truck empty and load vertical load differs larger, produce larger vertical deflection displacement, again because fulcrum block 1 and five eyebar 2 form the braking point device of rigid construction form, so can cause the fulcrum block and the other strength of fulcrum that are connected on bolster, even between other braking parts, also there is other strength, thereby cause car brakeing improper release, stop off inspection, affects normal vehicle Transportation Organization.
For head it off, as shown in Figure 3, in one, rod-pulling type bogie truck braking point device adopts chain link 8 flexible connection devices such as grade to substitute rigid support, has eliminated the other strength phenomenon of braking parts.But drop-down rod-type bogie truck, due to fulcrum power effect by compression under braking mode, cannot adopt the flexible connection devices such as chain link.
Summary of the invention
The problem to be solved in the present invention is exactly to provide a kind of flexible braking point device that is suitable for drop-down rod-type bogie truck for above deficiency, to solve railway wagon brake improper release problem.Its technical scheme is as follows:
It comprises brake beam, lever and lower link, on the bolster of bogie truck, fulcrum block is installed, and connects braking fulcrum on fulcrum block, and the braking fulcrum other end is connected with lever.Its gordian technique is the connecting panel that fulcrum block comprises adapter plate and is connected with adapter plate, on connecting panel, have strip hole, the clamping plate that braking fulcrum comprises otic placode and is connected with otic placode, adapter plate is arranged on the bolster of bogie truck, otic placode is connected with connecting panel by strip hole, and clamping plate are connected with lever.
Compared with prior art, the present invention has following beneficial effect:
1, on the connecting panel of fulcrum block, have strip hole, the otic placode of braking fulcrum passes strip hole by staking pin, realizing fulcrum block connects with the flexibility of braking fulcrum, make to brake fulcrum and there is adaptive characteristic, can adapt to the difference of railway truck empty and load amount of deflection, rationally discharge railway truck sky, the poor impact on brake equipment of loaded vehicle amount of deflection, can significantly reduce the other strength phenomenon between railway goods train bogie brake equipment, effectively solve car brakeing improper release problem.
2, fulcrum is connected by otic placode and connecting panel with fulcrum block, adopts planar compressed structure design, and it connects reliable, and stable performance improves safety factor of travel.
3, fulcrum block adopts this non-welding manner of pulling rivet (or bolt) to be fastened on bolster, has reduced welding impact, and assembly and disassembly is convenient.
4, between fulcrum and fulcrum block, adopt the fasteners such as staking pin to connect, realized flexible action function between the two.
5, structure design novelty of the present invention, ingenious, release of brake reliable effect.

The specific embodiment
Referring to Fig. 4～Fig. 8, the present invention includes brake beam 5, lever 4 and lower link 6, on the bolster of bogie truck, fulcrum block is installed, on fulcrum block, connect braking fulcrum, the braking fulcrum other end is connected with lever 4.Its gordian technique is the connecting panel 12 that fulcrum block comprises adapter plate 10 and is connected with adapter plate 10, on connecting panel 12, have strip hole 13, the clamping plate 11 that braking fulcrum comprises otic placode 14 and is connected with otic placode 14, adapter plate 10 is arranged on the bolster of bogie truck, otic placode 14 is connected with connecting panel 12 by strip hole 13, and clamping plate 11 are connected with lever 4.
Described adapter plate 10 is arranged on the bolster of bogie truck by pulling rivet 16 or bolt.
On described otic placode 14, have circular hole 15, circular hole 15 is connected by staking pin 9 with strip hole 13, thereby fulcrum block is connected with braking fulcrum.
Between connecting panel 12 and otic placode 14, wear-resisting backing plate is installed, to reduce the abrasion of abrasion position, is convenient to safeguard.
Between staking pin 9 and strip hole 13, wear-resisting roll sleeve is set, to reduce the abrasion of abrasion position, is convenient to safeguard.
