Abstract
The utility model discloses a kind of unitary tape dovetail steel back, including steel back body, the upper center of the steel back body is equipped with dovetail body, angle is equipped between the upper end of the steel back body and dovetail body, and the steel back body and dovetail body are integral structures.The beneficial effects of the utility model：Steel back, using shaping is integrally machined, regardless of left and right piece, becomes an entirety, in replacement process, reduces the amount of labour of once mounting, improve labor efficiency with dovetail；At the same time because the utility model is whole piece, the uniformity of brake lining friction piece flatness is improved in process.
Description
Technical field
Train braking device technical field is the utility model is related to, it particularly relates to a kind of unitary tape dovetail steel back.
Background technology
With the rapid development of China's science and technology, in recent years, China Transportation Industry have advance by leaps and bounds it is considerable
Development；China Railway High-speed has occupied first place in the world at present through unremitting effort in a few years；The year two thousand twenty is expected, in high-speed railway
Journey covers cities more than 500,000 populations close to 20,000 kilometers, and China four indulges four horizontal railway personal rapid transit systems and will build comprehensively at that time
Into China will enter the high ferro epoch.
With the raising of train speed, how the train of high-speed cruising safely to be stopped be one be related to life and
The major issue of property safety；Train braking has the various ways such as resistive braking, magnetic rail braking, eddy-current brake.But no matter use
Which kind of mode of braking, friction catch are indispensable.Friction catch mode is that kinetic energy is converted into thermal energy by rubbing, then
It is melt into air.The friction catch generally use of bullet train is disc type brake mode, using between brake disc and brake pad
Mutual rubbing action achieve the purpose that consume train momentum.Therefore, the performance of both parts is related to train as one
Importance safe for operation.
There are the series such as CRH1, CRH2, CRH3, CRH5 and CRH380 known to the high-speed EMU that China railway is started,
All using disc type brake mode；Generally used in pairs when brake lining uses, be divided into left and right two panels.
A pair of of brake lining will repeat installation twice in split type brake lining form installation process, and efficiency is low.On the other hand, lock
In process there are certain machining deviation, two panels brake lining is combined into a pair of in use, can not ensure the flat of two panels brake lining piece
Row degree.
Utility model content
, can the utility model proposes a kind of unitary tape dovetail steel back for the above-mentioned technical problem in correlation technique
Overcome the above-mentioned deficiency of the prior art.
To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of unitary tape dovetail steel back, including steel back body, the upper center of the steel back body are equipped with dovetail body,
Angle is equipped between the upper end of the steel back body and dovetail body, and the steel back body and dovetail body are integral type knots
Structure.
Further, the angle number of degrees of the steel back body and dovetail body are 53 °.
The beneficial effects of the utility model：Steel back and dovetail are using being integrally machined shaping, regardless of left and right piece, become one it is whole
Body, in replacement process, reduces the amount of labour of once mounting, improves labor efficiency；At the same time because the utility model is whole piece,
The uniformity of brake lining friction piece flatness is improved in process.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, drawings in the following description are only the utility model
Some embodiments, for those of ordinary skill in the art, without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of top view of unitary tape dovetail steel back according to the utility model embodiment；
Fig. 2 is a kind of left view of unitary tape dovetail steel back according to the utility model embodiment；
In figure：
1st, steel back body；2nd, dovetail body；3rd, angle.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art's all other embodiments obtained, all belong to
In the scope of the utility model protection.
As shown in Figs. 1-2, a kind of unitary tape dovetail steel back according to the utility model embodiment, including steel back sheet
Body 1, the upper center of the steel back body 1 is equipped with dovetail body 2, between the upper end of the steel back body 1 and dovetail body 2
Equipped with angle 3, and the steel back body 1 and dovetail body 2 are integral structures.
In one embodiment, 3 number of degrees of angle of the steel back body 1 and dovetail body 2 are 53 °.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, the utility model uses numerically-controlled machine tool integrated processing technology, to process the dovetail of brake lining and steel
The back of the body so that between the dovetail and steel back of brake lining by initial point connection become face connection, and then in braking procedure brake lining by
Power is distributed across whole dovetail and the joint face of steel back, uniform force, while regardless of left and right piece, can ensure in process
The uniformity of brake lining friction piece flatness, phenomena such as avoiding eccentric wear, occur, and improve replacement efficiency.
The angle number of degrees of steel back described in the utility model and dovetail are 53 °, are to preferably coordinate miscellaneous part to pacify
Full work, and then improve security performance.
In conclusion steel back described in the utility model is used with dovetail is integrally machined shaping, regardless of left and right piece, become one
A entirety, in replacement process, reduces the amount of labour of once mounting, improves labor efficiency；At the same time because the utility model is one whole
Piece, improves the uniformity of brake lining friction piece flatness in process.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
