The invention discloses a brake disc, an inertia test bench, a brake system and a vehicle, and relates to the technical field of vehicle braking, and the brake disc is composed of the following components in percentage by mass: more than or equal to 3.7% of C, more than or equal to 1.6% of Si, 0.4-0.8% of Mn, less than or equal to 0.1% of P, less than or equal to 0.1% of S, less than or equal to 0.2% of Cr, less than or equal to 0% of Ni, 2% of Mo, less than or equal to 0.6% of Mo, 0.4-0.5% of Cu and the balance of Fe. The addition amount of the Cu element is reasonably adjusted within the component range of the brake disc, and the mass percent of the Cu element is 0.4%-0.5%, so that the MPU phenomenon between the brake disc and a friction plate is reduced, the possibility that obvious scratches appear on the surface of the brake disc is reduced, the visual effect of the brake disc is improved, and the service life of the brake disc is prolonged. And the possibility of brake noise or brake jitter of the brake disc can be reduced, so that the brake performance and reliability of the brake system are improved, and better use experience is provided for users.

    本发明公开了一种制动盘、惯量试验台、制动系统及车辆,涉及车辆制动技术领域,其中制动盘由以下质量百分比计的成分组成:C≥3.7%,Si≥1.6%,Mn:0.4%~0.8%,P≤0.1%,S≤0.1%,Cr≤0.2%,Ni≤0,2%,Mo≤0.6%,Cu:0.4%~0.5%,余量为Fe。本发明通过在制动盘成分范围内合理地调整了Cu元素的加入量,使Cu元素的质量百分比计为0.4%~0.5%,从而减少了制动盘与摩擦片之间的MPU现象,不仅降低了制动盘的表面出现明显划痕的可能性,提升了制动盘的视觉效果,还可以降低制动盘制动噪声或制动抖动发生的可能性,进而提高了刹车系统的刹车性能和可靠性,为用户提供更好的使用体验。
