圖1至圖5描繪碟式刹車轉子10之例示性實施例。在使用中,碟式刹車轉子10通常附接至小型車輛之輪轂。藉助於實例,在圖1中,碟式刹車轉子10展示為附接至設置於腳踏車上之前輪W之轂HB。碟式刹車轉子10因此在此例示性實施例中為腳踏車碟式刹車轉子。當將施加刹車力時,安裝於腳踏車之前叉F上的碟式刹車鉗C之襯墊接觸碟式刹車轉子10。如圖2及圖4中所展示,碟式刹車轉子10包括第一部分12及第二部分14。第一部分12係由第一材料製成。在此例示性實施例中,第一材料為鐵或鋼。更具體言之,在此例示性實施例中,第一材料為不鏽鋼。但在必要及/或需要時,在抵抗熱或機械變形方面有效的任何其他材料可用作第一材料。第二部分14係由不同於第一材料之第二材料製成。在此例示性實施例中,第二材料為鋁或鋁合金。更具體言之,第二材料為對摩擦熱具有相對較高穩定性之鋁合金。但在耗散摩擦熱方面有效的任何其他材料可用作第二材料。第二部分14在非平行於旋轉軸線A之連接方向上連接至第一部分12。因此,如圖2及圖4中所展示,碟式刹車轉子10包括連接部分16,連接部分16在連接方向上設置於第一部分12與第二部分14之間以便將第一部分12連接至第二部分14。如圖2及圖3中所展示,旋轉軸線A對應於碟式刹車轉子10之中心軸線,在碟式刹車轉子10安裝至腳踏車輪W之安裝狀態中,旋轉軸線A亦為轂HB之中心軸線。 1-5 depict an exemplary embodiment of a disc brake rotor 10 . In use, the disc brake rotor 10 is typically attached to the hub of a small vehicle. By way of example, in Figure 1, a disc brake rotor 10 is shown attached to a hub HB of a front wheel W provided on a bicycle. The disc brake rotor 10 is thus a bicycle disc brake rotor in this exemplary embodiment. When the braking force is to be applied, the pad of the disc brake caliper C mounted on the front fork F of the bicycle contacts the disc brake rotor 10 . As shown in FIGS. 2 and 4 , the disc brake rotor 10 includes a first portion 12 and a second portion 14 . The first portion 12 is made of a first material. In this exemplary embodiment, the first material is iron or steel. More specifically, in this exemplary embodiment, the first material is stainless steel. However, any other material effective in resisting thermal or mechanical deformation may be used as the first material if necessary and/or desired. The second portion 14 is made of a second material different from the first material. In this exemplary embodiment, the second material is aluminum or an aluminum alloy. More specifically, the second material is an aluminum alloy with relatively high stability to frictional heat. But any other material effective in dissipating frictional heat can be used as the second material. The second portion 14 is connected to the first portion 12 in a connecting direction that is not parallel to the axis of rotation A. Thus, as shown in FIGS. 2 and 4 , the disc brake rotor 10 includes a connecting portion 16 that is disposed between the first portion 12 and the second portion 14 in the connecting direction so as to connect the first portion 12 to the second portion 16 . Section 14. As shown in FIGS. 2 and 3 , the rotation axis A corresponds to the central axis of the disc brake rotor 10 , and in the mounted state of the disc brake rotor 10 to the bicycle wheel W, the rotation axis A is also the central axis of the hub HB .

根據此例示性實施例,連接方向為徑向平面P內垂直於旋轉軸線A之任何方向(參見圖3)。換言之,連接方向垂直於旋轉軸線A。但連接方向亦可為非平行於旋轉軸線A之其他方向。 According to this exemplary embodiment, the connection direction is any direction in the radial plane P that is perpendicular to the axis of rotation A (see FIG. 3 ). In other words, the connection direction is perpendicular to the axis of rotation A. However, the connection direction can also be other directions that are not parallel to the rotation axis A.
