    • An automotive disc brake assembly comprises a disc rotor made of graphite cast iron with a structure of pearlite, and a brake pad made of organic material. The disc rotor has a first thermal conductivity falling in a range from 0.090 to 0.140 cal/cm.sec..degree.C. The brake pad has second thermal conductivity falling in a range from 0.65 to 3.00 Kcal/mh.degree.C. The second thermal conductivity falls in a range from 0.65 to 0.98 Kcal/mh.degree.C. provided that the second thermal conductivity satisfies the following relationship with the first thermal conductivity:.lambda..sub.R .gtoreq.-0.152.times..lambda..sub.P +0.24where, .lambda..sub.R is first thermal conductivity, and .lambda..sub.P is the second thermal conductivity. The disc brake assembly is successful in improving heat check resistance ability which is substantially influenced by thermal conductivity of the disc rotor and the brake pad.
    • 一种汽车盘式制动器组件,包括由具有珠光体结构的石墨铸铁制成的圆盘转子和由有机材料制成的制动片。 圆盘转子的第一热传导率为0.090〜0.140cal / cm·sec。 制动片的第二热传导率在0.65-3.00Kcal / mh℃的范围内。第二热传导率在0.65至0.98Kcal / mh℃的范围内。只要第二导热系数满足 与第一热导率之间的关系:λR> = = 0.152×λP + 0.24其中,λR是第一热导率,λP是第二导热系数。 盘式制动器组件成功地提高了基本上受到盘式转子和制动衬块的导热性的影响的耐热检查能力。
