Description

Brake Disc

本創作係與煞車裝置有關，特別是有關於一種煞車碟盤。This work is related to brake devices, in particular to a brake disc.

煞車碟盤固定於車輪，配合卡鉗挾持住煞車碟盤之二側面，透過二者相互接觸產生的磨擦力來使得車輪停止轉動，以達到煞車之目的。可以理解的，卡鉗與煞車碟盤摩擦時會產生高溫，長久處於高溫狀態的煞車碟盤會有變形、結構變弱之缺失，將會導致煞車效率低落及使用壽命減短之問題，因此，煞車碟盤一般會貫設複數散熱孔，以增加煞車碟盤之表面積，以期能有較佳散熱效果。The brake disc is fixed to the wheel, and the caliper clamps the two sides of the brake disc. The friction generated by the contact between the two stops the wheel from rotating, thus achieving the purpose of braking. It is understandable that the friction between the caliper and the brake disc will generate high temperature. The brake disc that is in a high temperature state for a long time will be deformed and weakened, which will lead to low braking efficiency and shortened service life. Therefore, the brake disc is generally provided with multiple heat dissipation holes to increase the surface area of the brake disc in order to achieve a better heat dissipation effect.

然而，在此類習知裝配技術中之煞車碟盤皆只設有軸向延伸之散熱孔，此軸向孔結構並無法有效利用空氣對流，故習知煞車碟盤整體散熱功能依然偏差且煞車性能降低。因此，有必要提供一種新穎且具有進步性之煞車碟盤，以解決上述之問題。However, the brake discs in the conventional assembly technology are only provided with axially extending heat dissipation holes. The axial hole structure cannot effectively utilize air convection, so the overall heat dissipation function of the conventional brake disc is still deviated and the braking performance is reduced. Therefore, it is necessary to provide a novel and advanced brake disc to solve the above problems.

本創作之主要目的在於提供一種煞車碟盤，可以有有效導引空氣流向，進而有較佳的散熱效果。The main purpose of this invention is to provide a brake disc that can effectively guide air flow and thus have a better heat dissipation effect.

為達成上述目的，本創作提供一種煞車碟盤，包括：一主體、至少一第一散熱孔及至少一第二散熱孔。該主體定義有一軸向及一徑向；該至少一第一散熱孔斜向該軸向地貫穿該主體；該至少一第二散熱孔沿該徑向之方向延伸地貫設於該主體，該至少一第二散熱孔包含有一第一通口及一第二通口，該第一通口連通該至少一第一散熱孔，該第二通口供連通外界，圍構該第一通口之口緣輪廓異於圍構該第二通口之口緣輪廓。To achieve the above-mentioned purpose, the invention provides a brake disc, comprising: a main body, at least one first heat dissipation hole and at least one second heat dissipation hole. The main body is defined with an axial direction and a radial direction; the at least one first heat dissipation hole penetrates the main body obliquely to the axial direction; the at least one second heat dissipation hole is extended and penetrates the main body along the radial direction, and the at least one second heat dissipation hole includes a first opening and a second opening, the first opening is connected to the at least one first heat dissipation hole, and the second opening is connected to the outside, and the edge contour surrounding the first opening is different from the edge contour surrounding the second opening.

以下僅以實施例說明本創作可能之實施態樣，然並非用以限制本創作所欲保護之範疇，文中所提之名詞前冠以的「一」或「至少一」並非對數量進行限制，依據需求亦可為「複數」個，此數量上之變化亦為所欲保護之範圍，合先敘明。The following is merely an example to illustrate possible implementations of the present invention, but it is not intended to limit the scope of protection for the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be stated in advance.

請參考圖1至圖6，其顯示本創作之一實施例，本創作之煞車碟盤包括：一主體1、至少一第一散熱孔2及至少一第二散熱孔3。Please refer to FIG. 1 to FIG. 6 , which show an embodiment of the present invention. The brake disc of the present invention includes: a main body 1 , at least one first heat dissipation hole 2 and at least one second heat dissipation hole 3 .

該主體1定義有一軸向11及一徑向12，該主體1呈環狀。該至少一第一散熱孔2斜向該軸向11地貫穿該主體1，透過傾斜的結構能與遭周空氣產生較多接觸面積，進而有助於導引空氣流動。該至少一第二散熱孔3沿該徑向12之方向延伸地貫設於該主體1，該至少一第二散熱孔3包含有一第一通口31及一第二通口32，該第一通口31連通該至少一第一散熱孔2，該第二通口32供連通外界，圍構該第一通口31之口緣輪廓異於圍構該第二通口32之口緣輪廓，明確地說，該第一通口31係傾斜延伸，該第一通口31之開口面積係大於該第二通口32之開口面積，傾斜大面積的該至少一第一散熱孔2能產生指向性的導流效果及讓氣流快速流出之功效。The main body 1 defines an axial direction 11 and a radial direction 12, and the main body 1 is annular. The at least one first heat dissipation hole 2 penetrates the main body 1 obliquely to the axial direction 11, and can generate more contact area with the surrounding air through the inclined structure, thereby helping to guide air flow. The at least one second heat dissipation hole 3 is extended along the radial direction 12 and penetrates the main body 1. The at least one second heat dissipation hole 3 includes a first opening 31 and a second opening 32. The first opening 31 is connected to the at least one first heat dissipation hole 2, and the second opening 32 is connected to the outside. The edge contour surrounding the first opening 31 is different from the edge contour surrounding the second opening 32. Specifically, the first opening 31 extends obliquely, and the opening area of the first opening 31 is larger than the opening area of the second opening 32. The at least one first heat dissipation hole 2 with a large inclined area can produce a directional guide effect and allow the airflow to flow out quickly.

當氣流沿該軸向11流經該至少一第一散熱孔2時，於該至少一第二散熱孔3會產生負壓吸力，令該第二通口32會主動吸入周遭空氣並通過該第一通口31而由該至少一第一散熱孔2一同流出，使得該主體1於該軸向11及該徑向12上二種方向都能同時有氣流流通而能有效散熱。When the air flows through the at least one first heat dissipation hole 2 along the axial direction 11, negative pressure suction is generated in the at least one second heat dissipation hole 3, so that the second opening 32 actively inhales the surrounding air and flows out from the at least one first heat dissipation hole 2 through the first opening 31, so that the main body 1 can have airflow in both the axial direction 11 and the radial direction 12 at the same time to effectively dissipate heat.

較具體地說，該至少一第一散熱孔2於該主體1之相對二側分別形成有一第一導流口21及一第二導流口22，該第一導流口21之輪廓與該第二導流口22之輪廓分別呈橢圓形以期能有較大的進出口截面積，並且該第一導流口21之口徑係大於該第二導流口22之口徑，以便於承接氣體流入。更具體地說，面向該第一導流口21觀之，各該第一散熱孔2之右側之一第一傾斜角51係大於各該第一散熱孔2之左側之一第二傾斜角52，當該主體1轉動時，不同傾斜角度的左側及右側能有效控制氣流流出該主體1後的流向。More specifically, the at least one first heat dissipation hole 2 is formed with a first guide port 21 and a second guide port 22 on two opposite sides of the main body 1, and the contours of the first guide port 21 and the second guide port 22 are respectively elliptical in order to have a larger inlet and outlet cross-sectional area, and the diameter of the first guide port 21 is larger than the diameter of the second guide port 22, so as to receive the inflow of gas. More specifically, when facing the first guide port 21, a first tilt angle 51 on the right side of each first heat dissipation hole 2 is larger than a second tilt angle 52 on the left side of each first heat dissipation hole 2. When the main body 1 rotates, the left and right sides with different tilt angles can effectively control the flow direction of the airflow after it flows out of the main body 1.

該煞車碟盤另包含有複數第一散熱組41與複數第二散熱組42，該至少一第一散熱孔2之數量為複數個，複數該第一散熱孔2分布於該主體1而能較全面性地進行散熱，該主體1包含有於該軸向11上相互背對之一第一側面14與一第二側面15，各該第一散熱組41包含有複數該第一導流口21係開設於該第一側面14的複數該第一散熱孔2，各該第二散熱組42包含有複數該第一導流口21係開設於該第二側面15的複數該第一散熱孔2。透過複數該第一散熱組41與複數該第二散熱組42的配置方式，能確保該主體1於該軸向11上的二側的散熱能力相等，而不會有單側溫度過高之情況發生。The brake disc further includes a plurality of first heat dissipation groups 41 and a plurality of second heat dissipation groups 42. The number of the at least one first heat dissipation hole 2 is plural. The plurality of first heat dissipation holes 2 are distributed on the main body 1 so as to dissipate heat more comprehensively. The main body 1 includes a first side surface 14 and a second side surface 15 opposite to each other in the axial direction 11. Each of the first heat dissipation groups 41 includes a plurality of first air guide ports 21, which are the plurality of first heat dissipation holes 2 opened on the first side surface 14. Each of the second heat dissipation groups 42 includes a plurality of first air guide ports 21, which are the plurality of first heat dissipation holes 2 opened on the second side surface 15. By disposing the plurality of first heat dissipation groups 41 and the plurality of second heat dissipation groups 42 , it is ensured that the heat dissipation capacity of the two sides of the main body 1 in the axial direction 11 is equal, and the temperature of one side will not be too high.

於本實施例中，該主體1另定義有一周向13，複數該第一散熱組41與複數該第二散熱組42沿該周向13呈交替配置，以均勻該第一側面14與該第二側面15的散熱效果。並且，複數該第一散熱組41之數量等同於複數該第二散熱組42之數量，各該第一散熱組41之第一散熱孔2的數量等同於各該第二散熱組42之第一散熱孔2的數量，而能有更均勻且全面地散熱效果。In this embodiment, the main body 1 further defines a circumferential direction 13, and the plurality of first heat dissipation groups 41 and the plurality of second heat dissipation groups 42 are alternately arranged along the circumferential direction 13 to uniformly dissipate heat on the first side surface 14 and the second side surface 15. In addition, the number of the plurality of first heat dissipation groups 41 is equal to the number of the plurality of second heat dissipation groups 42, and the number of the first heat dissipation holes 2 of each first heat dissipation group 41 is equal to the number of the first heat dissipation holes 2 of each second heat dissipation group 42, so that a more uniform and comprehensive heat dissipation effect can be achieved.

可以理解的是，配合複數該第一散熱孔2之數量，該至少一第二散熱孔3之數量較佳亦為複數個，複數該第二散熱孔3係沿該周向13呈等間隔角度配置，以期能均勻地從該主體1之周遭吸取空氣；其中，各該第二散熱孔3連通一該第一散熱孔2。It can be understood that, in conjunction with the number of the plurality of first heat dissipation holes 2, the number of the at least one second heat dissipation hole 3 is preferably also plural, and the plurality of second heat dissipation holes 3 are arranged at equal intervals along the circumferential direction 13 so as to evenly absorb air from the surroundings of the main body 1; wherein each second heat dissipation hole 3 is connected to one of the first heat dissipation holes 2.

較佳地，複數該第二散熱孔3於該徑向12上的長度不盡相同，以兼顧該主體1於該徑向12上不同深度位置的散熱效果。Preferably, the lengths of the plurality of second heat dissipation holes 3 in the radial direction 12 are different, so as to take into account the heat dissipation effects of the main body 1 at different depths in the radial direction 12 .

較具體地說，以排列方式觀之，複數該第一散熱孔2可進一步區分成複數單元6，各該單元6包含有相同數量且沿一圓弧線7呈間隔排列的複數該第一散熱孔2。更具體地說，該主體1另包含有一中心點16及一虛擬圓輪廓17，該虛擬圓輪廓17之圓心即為該中心點16，複數該單元6之圓弧線7之圓心係呈等間隔角度地坐落於該虛擬圓輪廓17上，該圓弧線7至該中心點16的距離係沿順時針方向縮短，此排列設計方式能確保該主體1於該徑向12及該周向13上不同位置皆能有效進行散熱。More specifically, in terms of arrangement, the plurality of first heat dissipation holes 2 can be further divided into a plurality of units 6, each of which includes the same number of the plurality of first heat dissipation holes 2 arranged at intervals along a circular arc line 7. More specifically, the main body 1 further includes a center point 16 and a virtual circular outline 17, the center of the virtual circular outline 17 is the center point 16, the centers of the circular arc lines 7 of the plurality of units 6 are located on the virtual circular outline 17 at equal intervals, and the distance from the circular arc line 7 to the center point 16 is shortened in the clockwise direction. This arrangement design can ensure that the main body 1 can effectively dissipate heat at different positions in the radial direction 12 and the circumferential direction 13.

透過此設計方式進行複數該第一散熱孔2的配置，相當便利於生產端快速得到所欲變動後的複數該第一散熱孔2的配置位置，舉例來說，生產端僅需要改變複數該單元6之圓弧線7之圓心坐落於該虛擬圓輪廓17之數量與間隔角度，即可以迅速於電腦模擬中生成。By configuring the plurality of first heat dissipation holes 2 in this design method, it is very convenient for the production end to quickly obtain the desired configuration positions of the plurality of first heat dissipation holes 2. For example, the production end only needs to change the number and spacing angle of the centers of the arc lines 7 of the plurality of units 6 located on the virtual circular contour 17, and it can be quickly generated in the computer simulation.
