碟式制动器安装接口为花键式

There are 2 common disc brake mounting interfaces, splined and center lock. Disc brakes with splined interfaces are more common. They are usually easier to install. The center lock system requires a tool to remove the locking ring on the disc hub. Six-bolt rotors are easier to install and require only 6 bolts. The center lock system is commonly used with performance road bikes.
柱式碟刹需要柱式转接器，而平装式碟刹则不需要。柱式转接器更为常见，常用于碳纤维山地车，而平装式接口正逐渐成为公路车和砾石公路车的标准配置。不过，所有碟刹转接器都可调节以适应不同的碟片尺寸。公路车通常使用 160 毫米碟片，而山地车则使用 180 毫米或 200 毫米碟片。

螺旋花键式碟刹安装接口

螺旋花键式盘式制动器安装接口采用花键连接轮毂和制动盘。这种花键连接允许制动盘和轮毂之间有较大的径向和旋转位移。如果花键连接松动，制动盘相对于轮毂的移动会导致异响。
The splines on the brake disc and hub are connected via an air gap. The air gap helps reduce heat conduction from the brake disc to the hub. The present invention addresses problems of noise, heat, and retraction of brake discs at the release of the brake. It also addresses issues with skewing and dragging. If you’re unsure whether this type of mounting interface is right for you, consult your mechanic.
Disc brake mounting interfaces that are helix-splined may be used in conjunction with other components of a wheel. They are particularly useful in disc brake mounting interfaces for hub-to-hub assemblies. The spacer elements, which are preferably located circumferentially, provide substantially the same function no matter how the brake disc rotates. Preferably, 3 spacer elements are located around the brake disc. Each of these spacer elements has equal clearance between the splines of the brake disc and the hub.
间隔元件 6 包括螺旋弹簧部分 6.1 和沿切向延伸的钩状结构 6.4。这些钩状结构在两个方向上均与制动盘 1 抵靠。螺旋弹簧部分 5.1 和 6.1 具有足够的刚度以吸收径向冲击。间隔元件沿啮合区域的圆周布置。
A helical splined disc mount includes a stabilizing element formed as a helical spring. The helical spring extends to the disc’s splines and teeth. The ends of the extension extend in opposite directions, while brackets at each end engage with the disc’s splines and teeth. This stabilizing element is positioned axially over the disc’s width.
Helical splined disc brake mounting interfaces are popular in bicycles and road bicycles. They’re a reliable, durable way to mount your brakes. Splines are widely used in aerospace, and have a higher fatigue life and reliability. The interfaces between the splined disc brake and BB spindle are made from aluminum and acetate.
由于花键轮毂以螺旋方式安装碟片，弹簧钢丝与碟片 2 将紧密接触。弹簧钢丝与碟片接触时，会产生均匀分布在整个碟片上的摩擦力。这使得碟片能够进行大范围的轴向运动。与同类产品相比，采用螺旋花键的碟式制动器安装接口具有更高的强度和刚度。
螺旋花键式碟刹安装接口可以有多种花键表面。花键表面是碟刹安装接口中最常见的类型。它们通常由不锈钢或铝制成，可用于各种应用。但是，花键式碟刹安装座无法支撑带有超大尺寸刹车卡钳的碟刹盘。
