Description
Technical field
The utility model is related to train braking field, especially a kind of powder metallurgy brake pad.
Background technology
The braking of Railway High Speed Train is with two kinds：Electric braking and aerobraking.Bullet train generally use under general condition
The preferential mode of braking of electric braking, and emergency braking is in an emergency in train operation in order to prevent such as train fault
In the case of the brake tool taken.Its principle is that the powder metallurgy brake pad of brake clamp is fitted closely with brake disc, to reach
The purpose of train braking.The backboard each two of brake pad group is a pair, is attached separately to the both sides of brake disc.
At home certain areas for example Qinghai, Tibet, the Northeast generator car also made using a kind of powder metallurgy brake pad
It is dynamic.These areas cause the vehicle grains of sand, ice in braking process since long-term dust storm is larger or the environment such as Heavy snow, low temperature
The impurity such as snow are clipped between brake pad and brake disc, and braking effect is caused to reduce, while brake disc is easy to scratch, and reduces and uses the longevity
Life.And the brake force larger injuring speed for accelerating brake disc when such vehicle braking.
Steel back is as carrying basis, and brake pad direct sintering is on the side of steel back.The steel back other side is metal plate bending
Dovetail connects between dovetail and steel back for riveted type.Brake lining is integrally directly connected to by dovetail with brake plate support.The company of steel back and dovetail
It is connected in riveted type, riveting is susceptible under big brake force and disengages phenomenon, influences traffic safety.Under big brake force, monoblock type is burnt
The brake pad complex forming technology of knot, it is unstable to be easy to cause total quality, chip off-falling occurs, collapses phenomena such as broken.And it once damages
Need integral replacing brake lining.Brake pad cannot contact brake disc simultaneously when integral sintered brake lining can have braking, cause rubbing surface
The inadequate phenomenon of product.
Utility model content
To overcome existing defect, the utility model proposes a kind of powder metallurgy brake pads.
A kind of powder metallurgy brake pad, including steel back, brake pad, the brake pad are mounted on steel back, wherein brake pad
Shape be hexagon.
Wherein, the quantity of brake pad is multiple, and gap is arranged between adjacent brake pad.
Wherein, brake pad includes friction piece and positioning pin, and the rub body and positioning pin are integrated, positioning pin end setting card
Slot.
Wherein, round first deep gouge is arranged in the reversed face of steel back dovetail, and disc spring is arranged in the first deep gouge；Steel back dovetail face is set
The second deep gouge is set, second deep gouge and the first deep gouge of tossing about are concentric, wherein clamp spring is arranged in the second deep gouge.
Wherein, positioning pin passes through disc spring and steel back from a deep gouge direction and is fixed by clamp spring.
Wherein, protrusion is arranged in the non-dovetail face of steel back, there is gap between brake pad and protrusion.
By powder metallurgy brake pad provided by the utility model, moulding process is simple, and is not easy to produce under big brake force
It is raw collapse it is broken, fall side；Replacement of products is simple, and steel back is reusable, reduces cost；Gap is big between brake pad, is easy to exclude husky
Grain, ice and snow etc. are conducive to extend the service life of brake disc；Brake pad, which can be done, to vert, and is conducive to increase brake pad and brake disc
Between contact area.
Description of the drawings
Fig. 1 is powder metallurgy brake pad front view.
Fig. 2 is powder metallurgy brake pad sectional view.
Specific implementation mode
It is detailed to a kind of powder metallurgy brake pad progress provided by the utility model in the following with reference to the drawings and specific embodiments
Thin description.
Fig. 1 and Fig. 2 shows a kind of powder metallurgy brake pad, including steel back 1, brake pad 2, the brake pad 2 are mounted on
Steel back 1, wherein the shape of brake pad 2 is hexagon.
The quantity of brake pad 2 is multiple, and gap is arranged between adjacent brake pad 2.
Brake pad 2 includes friction piece 20 and positioning pin 21, and the rub body 20 and positioning pin 21 are integrated, 21 end of positioning pin
Card slot 211 is set.
Round first deep gouge 14 is arranged in the reversed face of 1 dovetail of steel back, and disc spring 12 is arranged in the first deep gouge 14；1 dovetail of steel back
The second deep gouge 15 is arranged in face, and second deep gouge 15 and the first deep gouge 14 of tossing about are concentric, wherein clamp spring is arranged in the second deep gouge 15
13。
Positioning pin 21 passes through disc spring 12 and steel back 1 from 14 direction of a deep gouge and is fixed by clamp spring 13.
Protrusion is arranged in 1 non-dovetail face of steel back, has gap between brake pad 2 and protrusion.
Steel back is as carrying basis, using dovetail configuration directly with steel back as one.Reduce sheet metal structural dovetail and steel
The riveting of the back of the body.The non-dovetail face of steel back has a protrusion, and brake pad has certain interval, and protrusion can limit after installation is complete with protrusion
Brake pad rotates.There is gap between brake pad, hexagon brake pad can be done among disc spring holes slightly to vert.
Finally it should be noted that above example only to the technical solution of the utility model is described rather than to this technology
Method is limited, and the utility model can above extend to other modifications, variation, application and embodiment in application, and because
This thinks all such modification, variation, application, embodiments all within the scope of the spirit or teaching of the utility model.
