Embodiment
Below in conjunction with accompanying drawing of the present invention, be clearly and completely described technological scheme of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Be described further below in conjunction with accompanying drawing 1 ~ 10 pair of the specific embodiment of the present invention.
As shown in the structural representation of the high-performance new-energy automobile disc brake pad of a kind of optimal way of the present invention in Fig. 1,2, wherein in Fig. 1 schematic diagram, for the present invention arranges the structural representation after cooling unit and cooling bladder.Change for the ease of the details of observing in Fig. 2, the cooling unit in Fig. 2 and cooling bladder are omitted, does not draw in figure.In Fig. 3-7, emphasis is for illustrating chamfering structure, when carrying out cross section view, eliminates cooling unit and cooling bladder.One side of one-sided brake block 10 is braking surface 11, and cooling unit fits in the outer surface of described braking surface 11; Cooling unit is formed by multiple cooling unit 7 UNICOM of connecting; Described cooling unit 7 comprises metallic walls liquid storage chamber 71 and rubber wall liquid storage chamber 72.In prior art, because temperature rises instantaneously after brake block braking, cause brake block hydraulic performance decline, cause potential safety hazard.The present invention fits cooling unit on braking surface 11 for this reason, the temperature of high-performance new-energy automobile disc brake pad is reduced by the cooling liquid in cooling unit, make it avoid because high-performance new-energy automobile disc brake pad temperature raises instantaneously, the problem that the performance caused reduces occurs.But cooling liquid has respective volume and expands, for avoiding its expansion that heats up instantaneously after being heated, cooling unit 7 portion is caused to be split up, filling cooling liquid in cooling unit can reserve a fixed gap accordingly, ensureing that cooling liquid is when heating up rapidly, can not damage cooling unit.For solving the problems of the technologies described above, cooling unit is formed by multiple cooling unit 7 UNICOM of connecting by the present invention; Described cooling unit 7 comprises metallic walls liquid storage chamber 71 and rubber wall liquid storage chamber 72, and the structure material in metallic walls liquid storage chamber 71 is metal, is preferably brass.The structure material in rubber wall liquid storage chamber 72 is rubber.When in normal vehicle operation process, cooling liquid can be void-free filling in cooling unit, circulates, and under ensure that the inner chamber same volume of cooling unit, the amount of liquid of cooling liquid is more sufficient.If generation Emergency braking, high-performance new-energy automobile disc brake pad temperature raises rapidly, and cooling liquid thereupon temperature rises, and volume face is large, supports large rubber wall liquid storage chamber 72, and the cooling unit avoiding cooling liquid instantaneous expansion to cause damages.And in self inflation process of rubber wall liquid storage chamber 72, make coolant rate increase, rate of heat removal is also accelerated thereupon.When cooling unit cannot continue the radiating requirements meeting high-performance new-energy automobile disc brake pad, because cooling bladder 703 fits on cooling unit; Cooling bladder offers radiation hole, and described radiation hole arranges radiating net.Filling cooling liquid in cooling bladder 703, cooling liquid is chosen as purified water, and the evaporation of cooling heated liquid, distributes heat absorption by radiation hole, thus reduce the temperature of cooling unit further, assist cooling unit to derive the temperature of high-performance new-energy automobile disc brake pad.The grid cell [bin diameter of radiating net is 0.3mm.
Wherein, braking surface 11 comprises in four sides, the edge chamfer surface 12 of corresponding dual-side.The dual-side of this braking surface 11 comprises respectively, inner side edge 31 and outer side 32 and upper enclosed edge 41 and lower enclosed edge 42.As shown in Figure 1, inner side edge 31 with outer side 32 are offered the situation of chamfer surface 12.Wherein, inner side edge 31 is after brake block 10 assemble with brake disc 50, the corresponding sides in the middle part of brake block 10 and brake disc 50; Outer side 32 is after brake block 10 assembles with brake disc 50, the corresponding sides at brake block 10 and brake disc 50 edge.As shown in Figure 2, upper enclosed edge 41 with lower enclosed edge 42 are offered the situation of chamfer surface 12.Wherein, upper enclosed edge 41 is the side fillet of inner side edge 31 and outer side 32; Lower enclosed edge 42 is the opposite side fillet of inner side edge 31 and outer side 32.Above-mentioned chamfer surface 12 can according to the stress analysis of reality, select multiple chamfering mode, as shown in Figure 1, when offering chamfer surface 12 on inner side edge 31 with outer side 32, as shown in Figure 3, the chamfer angle of chamfer surface 12 can be preferably: 60 °, 45 ° or 30 °, and as a preferred embodiment of the present invention, the chamfering length of its chamfer surface 12 is: 1mm, 3mm or 4mm.Or as shown in Figure 4, its chamfer surface 12 is convex outward.As shown in Figure 2, when offering chamfer surface 12 in upper enclosed edge 41 with lower enclosed edge 42, as shown in Figure 5, the chamfer angle of chamfer surface 12 can be preferably: 60 °, 45 ° or 30 °, as a preferred embodiment of the present invention, the chamfering length of its chamfer surface 12 is: 1mm, 3mm or 4mm.Or as shown in Figure 6, its chamfer surface 12 is convex outward.Fix liner base plate 20 at the bottom welding of brake block 10, its brake block 10 thickness can be preferably: 15 ~ 17mm.The material of above-mentioned brake block 10 and liner base plate 20 can select high-quality steel and alloy material to make.
It can thus be appreciated that, as shown in Figure 10, the brake block in the present invention, after being assemblied in the brake disc 50 worn and torn, good cooperation can being formed with the brake disc 50 worn and torn, thus ensure that effective area of contact, this improves the reliability and safety of brake process.
For making vehicle in braking process, the noise produced is lower and increase local join strength, and in one embodiment of the invention, as shown in Figure 7, the joint bottom liner base plate 20 and brake block 10, also offers damping slot 61.At the flexible damped ring 60 of the mounted inside of damping slot 61.Its flexible damped ring 60 is corresponding to the shape of damping slot 61.Its flexible damped ring 60 can make by optimization polyurethane material, thus improve local join strength, and inhibit the generation of local vibrations (vibrations of the joint namely bottom liner base plate 20 and brake block 10) and noise, improve the join strength bottom liner base plate 20 and brake block 10 and serviceability, lower the situation producing and shake and snap.
Thus high-performance new-energy automobile disc brake pad of the present invention is by the edge chamfering structure at braking surface, the localized stress of brake block is made to obtain effective dispersion, therefore, reduce the stress raisers of brake block braking surface, make brake block stressed more average, thus, improve stability and the reliability of brake block.Improve the overall security of Motor Vehicle, and reduce use and the maintenance cost of Motor Vehicle
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
