Description
Technical field
The utility model is related to brake shoe technical field, and in particular to a kind of heat radiating type railway brake shoe.
Background technology
Braking is needed during train running, the braking component that direct friction wheel makes train stop is exactly brake shoe；Brake shoe
Typically cylinder iron or the tiles brake block that is made of other materials, hold wheel tread tightly in braking, wheel is stopped by friction
Rotate.
In this course, huge kinetic energy is changed into heat energy and is melt among air by brake apparatus.And this system
The quality of dynamic effect, but depends primarily on the dissipation capability of frictional heat energy.During using this mode of braking, brake shoe friction area
Small, most of thermic load is undertaken by wheel.Train speed is higher, and the thermic load of wheel is also bigger during braking.Such as cylinder iron lock
Watt, temperature can melt brake shoe；Even if using more advanced composite brake shoe, temperature can also be up to 400 ~ 450 DEG C.Work as wheel tread
When temperature is increased to a certain extent, tread wear, crackle or stripping will be made, service life has both been influenceed or influenceed traffic safety.
Present brake shoe selects resistant to elevated temperatures material to solve the above problems mostly, such as from composite brake shoe, but the solution
Certainly means can only tackle high temperature, but can not reduce the high temperature of brake shoe generation.
In publication No. CN102112356A patent document, a kind of shaping brake shoe is disclosed, is formed simultaneously by friction material
And with or without metal-backed.Along at least a portion of at least one side of brake shoe, provided with it is fibre-reinforced into
Type friction material layer, the invention can strengthen side, reduce the formation and extension of crackle, but it is scattered that effectively brake shoe can not be cooled
Heat.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of heat radiating type railway brake shoe, simple in construction, can be effective
The high temperature produced during ground reduction railway brake shoe work.
To realize object above, the utility model is achieved by the following technical programs：Heat radiating type railway brake shoe, including
Brake shoe body, brake shoe body includes being used to apply vehicle tread stressed rubbing surface, left surface and upper surface, rubbing surface difference
It is adjacent with left surface and upper surface, in addition to the first heat emission hole, the second heat emission hole and the 3rd heat emission hole, second heat emission hole from
Upper surface leads to lower surface, and the 3rd heat emission hole leads to right flank center from left surface center；First heat emission hole and
Three heat emission hole apertures are identical and lead to the 3rd heat emission hole from rubbing surface；Second heat emission hole is communicated with the 3rd heat emission hole.
Preferably, the brake shoe body is provided inwardly with groove at rubbing surface side center.
Preferably, brake shoe body back side center is provided with for fixed casting lug thereon.
Preferably, first heat emission hole, the second heat emission hole and the 3rd heat emission hole are circular hole.
Preferably, the aperture of second heat emission hole is more than the aperture of the first heat emission hole.
The utility model provides a kind of heat radiating type railway brake shoe, simple in construction, the first heat emission hole and the 3rd heat emission hole phase
Logical, the second heat emission hole and the 3rd heat emission hole are communicated, and this is conducive to heat to flow out, and can be effectively reduced the height produced during brake shoe work
Temperature, increases the service life of brake shoe；First heat emission hole, the second heat emission hole and the 3rd heat emission hole are that circular hole is because circular hole has very
Good stability, and it is symmetrical attractive in appearance；The aperture that the aperture of second heat emission hole is more than the first heat emission hole is more beneficial between the two
Stabilization.
