Specific embodiment
Below in conjunction with attached drawing of the invention, technical solution of the present invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this hair
The range of bright protection.
1~10 pair of a specific embodiment of the invention is described further with reference to the accompanying drawing.
Such as a kind of structural schematic diagram of the high-performance new-energy automobile disc brake pad of preferred embodiment of the invention in Fig. 1,2
It is shown, wherein in Fig. 1 schematic diagram, for the structural schematic diagram after present invention setting cooling device and cooling bladder.For the ease of observation
Details in Fig. 2 changes, in Fig. 2 cooling device and cooling bladder omitted, do not drawn in figure.Weight in Fig. 3-7
When carrying out cross section view, cooling device and cooling bladder is omitted to illustrate chamfering structure in point.The one side of unilateral brake block 10 is
Braking surface 11, cooling device fit in the outer surface of the braking surface 11；Cooling device by multiple cooling units 7 connect connection and
At；The cooling unit 7 includes metallic walls liquid storage chamber and rubber wall liquid storage chamber.In the prior art, due to temperature after brake block braking
Moment rising is spent, leads to piece performance decline of braking, causes security risk.The present invention is bonded cooling dress on braking surface 11 thus
It sets, the temperature of high-performance new-energy automobile disc brake pad is reduced by the coolant liquid in cooling device, avoids it due to height
The problem of performance new-energy automobile disc brake pad temperature moment increases, caused reduced performance occurs.But coolant liquid exists
Respective volume expansion is had after heated, to avoid the heating expansion of its moment, is caused 7 portion of cooling device to be split up, is filled accordingly
A fixed gap can be reserved loaded on the coolant liquid in cooling device, to guarantee that coolant liquid when rapidly heating up, will not damage cooling dress
It sets.In order to solve the above technical problems, the present invention is formed cooling device by multiple cooling units 7 series connection connection；It is described cooling single
Member 7 includes metallic walls liquid storage chamber and rubber wall liquid storage chamber, and the structure material of metallic walls liquid storage chamber is metal, preferably brass.Rubber
The structure material of glue wall liquid storage chamber is rubber.During normal vehicle operation, coolant liquid can be void-free filling in cooling dress
In setting, circulated, under the inner cavity same volume that ensure that cooling device, the amount of liquid of coolant liquid is more sufficient.If occurring
Emergency brake, high-performance new-energy automobile disc brake pad temperature rapidly increase, and temperature rises coolant liquid therewith, and volume face is big,
Big rubber wall liquid storage chamber is supportted, cooling device caused by coolant liquid instantaneous expansion is avoided to damage.And it is swollen in rubber wall liquid storage chamber itself
During swollen, so that coolant rate increases, rate of heat dispation is also accelerated therewith.When cooling device can not continue to meet high-performance it is new
When the radiating requirements of energy automobile disc brake pad, since cooling bladder 703 fits on cooling unit；Cooling bladder opens up heat dissipation
Radiator-grid is arranged in hole, the heat release hole.Filling cooling liquid in cooling bladder 703, cooling liquid are chosen as pure water, and cool down liquid
By thermal evaporation, heat absorption is distributed by heat release hole, to further decrease the temperature of cooling device, cooling device is assisted to export high property
The temperature of energy new-energy automobile disc brake pad.The grid cell diameter of radiator-grid is 0.3mm.
Wherein, braking surface 11 includes the edge fillet surface 12 of corresponding two sides in four sides.The braking surface 11
Two sides respectively include, inner side edge 31 and outer side edges 32 and upper enclosed edge 41 and lower enclosed edge 42.As shown in Figure 1, in inside
The situation of fillet surface 12 is opened up on side 31 and outer side edges 32.Wherein, it after inner side edge 31 is brake block 10 and the assembly of brake disc 50, stops
The corresponding sides at 50 middle part of vehicle piece 10 and brake disc；Outer side edges 32 are brake block 10 and brake after brake block 10 and the assembly of brake disc 50
The corresponding sides at 50 edge of hull.As shown in Fig. 2, opening up the situation of fillet surface 12 in upper enclosed edge 41 and lower enclosed edge 42.Its
In, upper enclosed edge 41 connect side with the side of outer side edges 32 for inner side edge 31；Lower enclosed edge 42 is inner side edge 31 and outer side edges 32
The other side connect side.Above-mentioned fillet surface 12 can select a variety of chamfering modes, as shown in Figure 1, working as according to actual stress analysis
When opening up fillet surface 12 on inner side edge 31 and outer side edges 32, as shown in figure 3, the chamfer angle of fillet surface 12 is preferable are as follows:
60 °, 45 ° or 30 °, as a preferred solution of the present invention, the chamfering length of fillet surface 12 are as follows: 1mm, 3mm or 4mm.Or
As shown in figure 4, its fillet surface 12 is convex outward.As shown in Fig. 2, when opening up chamfering in upper enclosed edge 41 and lower enclosed edge 42
When face 12, as shown in figure 5, the chamfer angle of fillet surface 12 is preferable are as follows: 60 °, 45 ° or 30 °, preferably as one kind of the invention
Scheme, the chamfering length of fillet surface 12 are as follows: 1mm, 3mm or 4mm.Or as shown in fig. 6, its fillet surface 12 is convex outward.?
Liner bottom plate 20 is welded and fixed in the bottom of brake block 10, and 10 thickness of brake block is preferable are as follows: 15~17mm.Above-mentioned brake block 10
And high-quality steel can be selected for the material of liner bottom plate 20 and alloy material is given and made.
It follows that as shown in Figure 10, the brake block in the present invention can be with after being assemblied in worn-out brake disc 50
Worn-out brake disc 50 forms preferable cooperation, to ensure that effective contact area, this improves brake process
Reliability and safety.
To make vehicle in braking process, generated noise is lower and increases local bonding strength, of the invention one
In kind embodiment, as shown in fig. 7, the junction of liner bottom plate 20 and 10 bottom of brake block, also opens up damping slot 61.It is damping
The mounted inside flexibility damped ring 60 of slot 61.Its flexible damped ring 60 is corresponding to the shape of damping slot 61.Its flexible damped ring 60
Preferable polyurethane material, which is given, to be made, to improve local bonding strength, and inhibits local vibrations (i.e. liner bottom plate
20 with the vibration of the junction of 10 bottom of brake block) and noise generation, improve liner bottom plate 20 and 10 bottom of brake block
Bonding strength and durability lower and generate the case where vibration is snapped.
To which high-performance new-energy automobile disc brake pad of the invention is by the edge chamfering structure in braking surface,
The local stress of brake block is set to have obtained effective dispersion, it therefore reduces the stress raisers of brake block braking surface, make to stop
Vehicle piece stress is more average, thus, improve the stability and reliability of brake block.The overall security of motor vehicle is improved,
And reduce the use and maintenance cost of motor vehicle
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
