刹车片厂家概述刹车片倒角

2020-04-22 10:45:57

刹车片厂家很多,但了解刹车片背板最上方会有一个倒角作用的不多。我们知道,许多刹车片背板最上方会有一个倒角。该倒角的作用是什么?今天我们就透过专利来分析。

专利号为EP2679852的专利“Brake backing plate with step-chamfer(一种带台阶倒角的刹车片背板)”公开了一种新型的倒角。虽然此专利中说的是新型倒角,但通过文中的说明,我们可以看到共同的作用。



A typical disc brake assembly includes a rotor whichis secured to the wheel of the vehicle for rotation therewith. The rotor has apair of opposed friction plates which are selectively engaged by portions of acaliper assembly. The caliper assembly is slidably supported by pins secured toan anchor plate. This anchor plate is in turn secured to a non-rotatablecomponent of the vehicle, such as the vehicle frame. A pair of brake pads aredisposed in the caliper assembly on opposite sides of the rotor.


典型的盘式制动器组件包括一转子,该转子固定在车辆的车轮上以便与之旋转。转子有一对对置摩擦片,它们由卡钳组件的部分有选择地啮合。卡钳组件可通过固定在锚板上的销钉滑动地支承。该锚板依次固定到车辆的非旋转部件,例如车架。一对刹车片设置在转子两侧的卡钳中。


The brake caliper is typically a cast solid piece ofiron, steel  aluminum. The casting process leaves rounded interior edges. Inorder to provide corner clearance with these rounded interior edges, the brakepads, themselves planar  angular, are frequently chamfered on one edge wherethe mounted pad faces the interior corner of the caliper.


制动钳通常是铸铁、钢或铝铸造件。铸造过程留下了圆润的内部边缘。为了给制动钳的内部圆角留出间隙,在刹车片面向制动钳内部圆角的边缘通常会留有倒角。

        The classic chamfer on the backing plate portion ofthe brake pad is an angled surface on the leading edge of the plate thatsubstantially mirrors ( at least provides complementary geometry with) therounded angled surface in the interior corners of the caliper. The chamfer andthe corner of the caliper, lacking points of potential unwanted contact, thushave clearance  each other.


刹车片背板上的倒角通常是具有一定角度的平面,其与制动钳内部圆角大体上相映射(或至少是一互补的形状)。背板倒角与制动钳的圆角由于没有潜在的不必要的接触点,因此彼有间隙。

However, such chamfered edges, while elegant , are noteasy to produce, particularly on brake backing plates  a rounded  otherirregular shaped leading edge.


然而,这种美观的倒角不易制造,特别是当背板上方是圆形或其它不规则形状的边缘时。


此专利将倒角由通常的斜角设计改为台阶性,以便于容易制造。

OK,总结下,刹车片背板设置倒角原因非常简单,是因为卡钳内侧拐角处有圆角,刹车片上如不设置倒角,装车时背板边缘就可能会与卡钳拐角处的圆角发生干涉,影响正常制动或产生振动、噪音等。


       作为刹车片厂家科普推广很重要,你get the point了吗?
