剎車碟盤Brake disc

本創作係有關一種剎車碟盤，尤指一種自行車剎車用之剎車碟盤。This creation is related to a brake disc, especially a brake disc for bicycle brakes.

習知自行車的剎車碟盤，常見是以鋼材為材質製成，主要係因鋼材具有良好的硬度和耐磨性，故而被廣泛使用。然而，隨著自行車輕量化的需求已成為趨勢，而鋼材使用在剎車碟盤的製作上有重量無法減輕，以及散熱不佳的問題，故有改良之必要。詳言之，若以較輕的材質取代鋼材而製作剎車碟盤，例如鋁材而言，其重量雖較鋼材輕了許多，且具有較佳之散熱效果，惟鋁材本身的結構強度較鋼材低，所製作剎車碟盤易有破損和耐磨性不佳的問題。The brake discs of the bicycles are often made of steel, which is widely used because of its good hardness and wear resistance. However, as the demand for lightweight bicycles has become a trend, and the use of steel in the manufacture of brake discs is not able to reduce the weight and the problem of poor heat dissipation, there is a need for improvement. In detail, if a brake disc is made by replacing the steel with a lighter material, such as aluminum, the weight is much lighter than steel and has a better heat dissipation effect, but the structural strength of the aluminum itself is lower than that of the steel. The brake disc produced is prone to damage and poor wear resistance.

因此，如何解決習知剎車碟盤之問題者，即為本創作之重點所在。Therefore, how to solve the problem of the conventional brake disc is the focus of this creation.

In various embodiments, the apertures 21 can be larger than the apertures 31, 41 and the apertures 22 can be larger than the apertures 32, 42.

如第1至3圖所示，內盤層2的外徑大於二外盤層3、4，二外盤層3、4相對而覆蓋在內盤層2之厚度方向的兩側面23，且內盤層2未被二外盤層3、4覆蓋的部分形成一夾持部24，此夾持部24係沿二外盤層3、4之圓周方向往外延伸。內盤層2之至少一第一孔和二外盤層3、4之至少一第二孔對應相通而形成該至少一通孔，內盤層2於至少一通孔中沒有未被二外盤層3、4覆蓋而裸露出側面23的部分。於本實施例中，係二外盤層3、4相對而覆蓋在內盤層2之厚度方向的兩側面23時，有孔21、31、41對應相通而形成通孔11，且有孔22、32、42對應相通而形成通孔12，孔21、31、41的大小和形狀相同，且孔22、32、42的大小和形狀亦相同，故於通孔11、12中，並不會有內盤層2之側面23裸露。若為孔21大於孔31、41，且孔22大於孔32、42之實施例時，亦不會有內盤層2之側面23裸露。As shown in FIGS. 1 to 3, the outer diameter of the inner disc layer 2 is larger than the outer outer disc layers 3, 4, and the outer outer disc layers 3, 4 are opposed to cover the two side faces 23 of the thickness direction of the inner disc layer 2, and the inner disc layer 2 The portion not covered by the two outer disc layers 3, 4 forms a grip portion 24 which extends outward in the circumferential direction of the outer disc layers 3, 4. The at least one first hole of the inner disk layer 2 and the at least one second hole of the two outer disk layers 3, 4 are connected to each other to form the at least one through hole, and the inner disk layer 2 is not uncovered by the outer disk layer 3, 4 in at least one through hole. Covering the portion of the side 23 that is exposed. In the present embodiment, when the two outer disk layers 3, 4 are oppositely covered on both side faces 23 of the thickness direction of the inner disk layer 2, the holes 21, 31, 41 are correspondingly communicated to form the through holes 11, and have holes 22, 32, 42 are formed to communicate with each other to form a through hole 12, the holes 21, 31, 41 are the same size and shape, and the holes 22, 32, 42 are also the same size and shape, so in the through holes 11, 12, there will be no The side 23 of the inner disc layer 2 is bare. If the hole 21 is larger than the holes 31, 41 and the hole 22 is larger than the holes 32, 42, the side 23 of the inner disk layer 2 will not be exposed.

1、本創作之剎車碟盤，其盤體1是藉由內盤層2和二外盤層3、4構成，且二外盤層3、4較內盤層2之材質為輕，因此在內盤層2具有適當的結構強度下，可由二外盤層3、4和內盤層2形成複合結構，而可達到剎車碟盤之盤體1輕量化之功效。1. The brake disc of the present invention, the disc body 1 is composed of an inner disc layer 2 and two outer disc layers 3, 4, and the outer disc layers 3, 4 are lighter than the inner disc layer 2, so the inner disc layer is 2 With proper structural strength, the composite structure can be formed by the two outer disc layers 3, 4 and the inner disc layer 2, and the weight of the disc body 1 of the brake disc can be achieved.

2、由於內盤層2可為鋼材而二外盤層3、4為鋁材，而為鋁材之二外盤層3、4設在為鋼材之內盤層2的側面，藉由鋁材具有良好的導熱係數，而可提高整體的熱傳導效率，故能讓盤體1達到良好的散熱效果。2. Since the inner disc layer 2 can be steel and the outer disc layers 3 and 4 are aluminum, the outer disc layers 3 and 4 of the aluminum material are disposed on the side of the inner disc layer 2 of the steel material, and the aluminum material has good properties. The thermal conductivity of the whole can improve the overall heat transfer efficiency, so that the disk body 1 can achieve a good heat dissipation effect.

以上所述實施例之揭示係用以說明本創作，並非用以限制本創作，故舉凡數值之變更或等效元件之置換仍應隸屬本創作之範疇。The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.

由以上詳細說明，可使熟知本項技藝者明瞭本創作的確可達成前述目的，實已符合專利法之規定，爰提出專利申請。From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
