    • PROBLEM TO BE SOLVED: To enhance heat radiation properties of a floating disc brake assembly, and to reduce the dragging thereof.SOLUTION: A disc brake assembly 8 incorporated in an automobile having a wheel 13 includes: a floating caliper 14; a brake rotor 10 having a disc 11; and a hat 12 in which the hat 12 is fixed to the wheel 13 by bolts. A hydraulic cylinder 16 presses an inner brake pad 20 against the disk 11, thereby moving the floating caliper 14 so that an outer brake pad 22 comes into contact with the disc 11. The rotor 10 is manufactured by using a material having such a thickness, a coefficient of thermal expansion, and thermal conductivity by perfect braking at 100 km/h and 0.9 vehicle gross weight, a thickness of the disc expands by at least 0.10 mm, the disk 11 is cooled off within 60 seconds after quitting the braking, and a thickness of the disc contracts by at least 0.05 mm from the expanded thickness at a temperature of 30°C or lower.
    • 要解决的问题:为了提高浮盘式制动器组件的散热性能并减少其拖动。解决方案:一种装在具有轮13的汽车中的盘式制动器组件8包括:浮动卡钳14; 具有盘11的制动转子10; 帽子12通过螺栓固定在车轮13上。 液压缸16将内部制动衬块20压靠在盘11上,从而移动浮动制动钳14,使得外部制动衬块22与盘11接触。转子10通过使用具有这种厚度的材料制造, 通过在100km / h和0.9车辆总重量的完美制动下的热膨胀系数和导热系数,盘的厚度扩展至少0.10mm,在退出制动之后的盘秒内,盘11被冷却,并且 在30℃或更低的温度下,盘的厚度从膨胀的厚度缩小至少0.05mm。
