Abstract
The present invention relates to the bogie of Railway Freight Transportation device, especially railway freight-car.It includes brake beam, lever and lower link, installs fulcrum block on the bolster of bogie.Its key technology is that fulcrum block includes installing plate and the connecting plate being connected with installing plate, having strip hole on connecting plate, braking fulcrum includes otic placode and the clamping plate being connected with otic placode, and installing plate is arranged on the bolster of bogie, otic placode is connected with connecting plate by strip hole, and clamping plate are connected with lever.The invention have the advantages that: on the connecting plate of fulcrum block, have strip hole, the otic placode of braking fulcrum passes strip hole by staking pin, realize the flexible connected of fulcrum block and braking fulcrum, make to brake fulcrum and there is adaptive characteristic, adapt to the difference of railway freight-car empty and load amount of deflection, rationally release railway freight-car sky, the impact on brake unit of the loaded vehicle amount of deflection difference, can substantially reduce the other strength phenomenon between railway goods train bogie brake unit, effectively solves car braking improper release problem.
Description
Technical field
A kind of drop-down rod-type bogie braking point device, relates to Railway Freight Transportation device, especially ferrum
The bogie that afloat is automobile-used.
Background technology
Tradition lorry cast steel bogie, braking point device such as Fig. 1 or Fig. 2 institute of its brake rigging
Show, including brake beam 5, lever 4 and lower link 6 or middle pull bar 7, the bolster of bogie welds
Fulcrum block 1, fulcrum block 1 is coupled five eyebar 2 of rigid structure as braking fulcrum, system by round pin 3
The activity supporting point other end is connected with lever 4.Owing to railway freight-car empty and load vertical load difference is relatively big, produce
Bigger vertical deflection displacement, again because fulcrum block 1 and five eyebar 2 constitute the braking of rigid structure form
Point device, so the fulcrum block and the other strength of fulcrum being connected on bolster, even other brakings zero can be caused
Other strength also occurring between parts, thus causes car braking improper release, stop off inspection, impact is normal
Vehicle transport tissue.
For solving this problem, as it is shown on figure 3, rod-pulling type bogie braking point device uses chain in one
Ring 8 flexible connection device such as grade substitutes rigid support, eliminates the other strength phenomenon of brake parts.Under but
Rod-pulling type bogie is due to fulcrum power effect by compression under on-position, it is impossible to use the flexible connection such as chain link
Connection device.
Summary of the invention
The problem to be solved in the present invention is aiming at above deficiency and provides one to be suitable for drop-down rod-type and turn to
The flexible braking point device of frame, to solve railway wagon brake improper release problem.Its technical scheme is such as
Under:
It includes brake beam, lever and lower link, installs fulcrum block, fulcrum on the bolster of bogie
Connecting braking fulcrum on seat, the braking fulcrum other end is connected with lever.Its key technology is that fulcrum block includes
Installing plate and the connecting plate being connected with installing plate, connecting plate has strip hole, and braking fulcrum includes ear
Plate and the clamping plate being connected with otic placode, installing plate is arranged on the bolster of bogie, and otic placode passes through strip hole
Being connected with connecting plate, clamping plate are connected with lever.
Compared with prior art, there is advantages that
1, having strip hole on the connecting plate of fulcrum block, the otic placode of braking fulcrum passes strip by staking pin
Hole, it is achieved fulcrum block and the flexible connected braking fulcrum so that braking fulcrum has adaptive characteristic, energy
Adapting to the difference of railway freight-car empty and load amount of deflection, rationally release railway freight-car sky, loaded vehicle amount of deflection difference are to braking
The impact of device, can substantially reduce the other strength phenomenon between railway goods train bogie brake unit, effectively solve
Car braking improper release problem.
2, fulcrum is connected by otic placode and connecting plate with fulcrum block, uses the design of planar compressed structure, and it is even
Connect reliable, stable performance, improves safety factor of travel.
3, fulcrum block uses pulling rivet (or bolt) this non-solder mode to be fastened on bolster, decreases
Welding impact, assembly and disassembly is convenient.
4, the securing members such as staking pin are used to couple between fulcrum with fulcrum block, it is achieved that flexible effect between the two
Function.
5, present configuration is novel in design, ingenious, release of brake reliable effect.

Detailed description of the invention
Seeing Fig. 4～Fig. 8, the present invention includes brake beam 5, lever 4 and lower link 6, at bogie
Bolster on fulcrum block is installed, fulcrum block connects braking fulcrum, braking the fulcrum other end and lever 4 are even
Connect.Its key technology is that fulcrum block includes installing plate 10 and the connecting plate 12 being connected with installing plate 10,
Having strip hole 13 on connecting plate 12, braking fulcrum includes otic placode 14 and the clamping plate being connected with otic placode 14
11, installing plate 10 is arranged on the bolster of bogie, and otic placode 14 is by strip hole 13 and connecting plate 12
Connecting, clamping plate 11 are connected with lever 4.
Described installing plate 10 is arranged on the bolster of bogie by pulling rivet 16 or bolt.
Having circular hole 15 on described otic placode 14, circular hole 15 is connected by staking pin 9 with strip hole 13, from
And fulcrum block is connected with braking fulcrum.
Wear-resisting backing plate is installed between connecting plate 12 and otic placode 14, to reduce the abrasion of abrasion position, it is simple to
Safeguard.
Wear-resisting roll sleeve is set between staking pin 9 and strip hole 13, to reduce the abrasion of abrasion position, it is simple to dimension
Protect.
