Description

剎車碟盤Brake disc

本發明係有關一種剎車碟盤，尤指一種自行車剎車用之剎車碟盤。The present invention relates to a brake disc, and more particularly to a brake disc for a bicycle brake.

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 conventional bicycles are usually made of steel, which is mainly used because steel has 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 cannot be reduced in weight, and the problem of poor heat dissipation, it is necessary to improve. In detail, if a lighter material is used instead of steel to make a brake disc, such as aluminum, although it is much lighter than steel and has better heat dissipation, the structural strength of aluminum itself is lower than that of steel. The brake discs produced are prone to breakage and poor wear resistance.

因此，如何解決習知剎車碟盤之問題者，即為本發明之重點所在。Therefore, how to solve the problem of the conventional brake disc is the focus of the present invention.

本發明目的之一，在於解決上述的問題而提供一種剎車碟盤，以達到剎車碟盤之盤體輕量化之功效。One of the objectives of the present invention is to solve the above problems and provide a brake disc to achieve the effect of reducing the weight of the disc body of the brake disc.

The material of the two outer disc layers 3 and 4 is lighter than that of the inner disc layer 2. In this embodiment, the inner disk layer 2 is made of steel, and the two outer disk layers 3 and 4 are made of aluminum.

本實施例中，內盤層2具有至少一第一孔，而二外盤層3、4各具有至少一第二孔。如第2圖所示，所述內盤層2之至少一第一孔，對應盤體1具有之通孔11而有孔21、且對應盤體1具有之通孔12而有孔22；所述外盤層3之至少一第二孔，對應盤體1具有之通孔11而有孔31、且對應盤體1具有之通孔12而有孔32；所述外盤層4之至少一第二孔，對應盤體1具有之通孔11而有孔41、且對應盤體1具有之通孔12而有孔42。其中，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。在不同之實施例時，孔21可大於孔31、41，且孔22可大於孔32、42。In this embodiment, the inner disk layer 2 has at least one first hole, and the two outer disk layers 3 and 4 each have at least one second hole. As shown in FIG. 2, at least one first hole of the inner disk layer 2 corresponds to the through hole 11 of the disk body 1 and has a hole 21, and corresponds to the through hole 12 of the disk body 1 and has a hole 22; At least one second hole of the outer disk layer 3 corresponds to the through hole 11 of the disk body 1 and has a hole 31, and corresponds to the through hole 12 of the disk body 1 and has a hole 32; The two holes have holes 41 corresponding to the through holes 11 provided in the disk body 1, and holes 42 corresponding to the through holes 12 provided in the disk body 1. The sizes and shapes of the holes 21, 31, and 41 are the same, and the sizes and shapes of the holes 22, 32, and 42 are also the same. In different embodiments, the hole 21 may be larger than the holes 31, 41, and the hole 22 may be larger than the holes 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 disk layer 2 is larger than that of the second outer disk layers 3 and 4, and the two outer disk layers 3 and 4 face each other and cover both sides 23 of the inner disk layer 2 in the thickness direction. A portion 24 that is not covered by the second outer disk layers 3 and 4 forms a clamping portion 24 that extends outward along the circumferential direction of the second outer disk layers 3 and 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 and 4 correspond to each other to form the at least one through hole. The at least one through hole of the inner disk layer 2 has no two outer disk layers 3 and 4. The portion covering the side surface 23 is exposed. In this embodiment, when the two outer disk layers 3 and 4 face each other and cover both sides 23 in the thickness direction of the inner disk layer 2, the holes 21, 31, and 41 correspond to each other to form the through hole 11, and the holes 22, 32 and 42 correspond to each other to form the through hole 12, and the sizes and shapes of the holes 21, 31, and 41 are the same, and the sizes and shapes of the holes 22, 32, and 42 are also the same. Therefore, in the through holes 11, 12, there is no The side surfaces 23 of the inner disc layer 2 are exposed. If the hole 21 is larger than the holes 31 and 41 and the hole 22 is larger than the holes 32 and 42, the side surface 23 of the inner disc layer 2 will not be exposed.

於上述之較佳實施例中，二外盤層3、4之導熱係數高於內盤層2，而內盤層2之耐磨性高於二外盤層3、4。此外，本實施例之內盤層2和二外盤層3、4所形成之盤體1具有安裝孔13，以此安裝孔13供盤體1可固定在自行車之花轂上。當然，也可以如第4圖所示之盤體1，只在外層盤3有安裝孔33，而可連接支架5而固定在自行車之花轂(圖中未示)，在此狀態下，內盤層2和外盤層4沒有和安裝孔33對應的孔洞。In the above-mentioned preferred embodiment, the thermal conductivity of the second outer disk layers 3, 4 is higher than that of the inner disk layer 2, and the abrasion resistance of the inner disk layer 2 is higher than that of the second outer disk layers 3, 4. In addition, the disc body 1 formed by the inner disc layer 2 and the two outer disc layers 3 and 4 in this embodiment has a mounting hole 13 through which the disc body 1 can be fixed on the hub of a bicycle. Of course, it is also possible to use the disc body 1 as shown in FIG. 4. Only the outer layer disc 3 has a mounting hole 33, and the bracket 5 can be connected to be fixed to the bicycle hub (not shown). In this state, the inner disc Layer 2 and outer disk layer 4 have no holes corresponding to the mounting holes 33.

由上述之說明，不難發現本發明之優點在於：From the above description, it is not difficult to find the advantages of the present invention:

1、本發明之剎車碟盤，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 and 4, and the material of the two outer disc layers 3 and 4 is lighter than that of the inner disc layer 2, so the inner disc layer 2 With appropriate structural strength, a composite structure can be formed from the two outer disc layers 3, 4 and the inner disc layer 2, and the lightening effect 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 disk layer 2 can be steel and the second outer disk layers 3 and 4 are aluminum, the second outer disk layers 3 and 4 are aluminum. The outer disk layers 3 and 4 are provided on the side of the inner disk layer 2 which is a steel material. The thermal conductivity of the plate 1 can improve the overall heat conduction 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發明，並非用以限制本發明，故舉凡數值之變更或等效元件之置換仍應隸屬本發明之範疇。The disclosure of the embodiments described above is used to illustrate the present invention, and is not intended to limit the present invention. Therefore, any change in numerical values or replacement of equivalent components should still belong to 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發明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, those skilled in the art can understand that the present invention can indeed achieve the aforementioned purpose, and indeed has met the provisions of the Patent Law, and filed a patent application.
