    • The present invention concerns a brake disc (1) for a disc brake having one or more sliding or not sliding discs on a hub or other central part. The brake disc (1) has an outer circumference (4) and an inner circumference (5) with a number of alternating teeth (2) and gaps (3) on the inner circumference (5). One or more measures are taken to reduce the risk of crack formation. One of said measures is to arrange areas (9, 10, 13, 14) of reduced material thickness at and/or adjacent each tooth (2). Said areas of reduced material thickness may be openings (9, 13, 14) having an axial or radial extent. Other measures include designing the teeth (2) and gaps (3) in an appropriate way and forming the brake disc with different properties at different parts.
    • 用于盘式制动器的制动盘(1)技术领域本发明涉及一种用于盘式制动器的制动盘(1) 制动盘(1)具有外圆周(4)和在内圆周(5)上具有多个交替齿(2)和间隙(3)的内圆周(5)。 采取一种或多种措施来降低裂纹形成的风险。 所述措施之一是在每个齿(2)处和/或邻近每个齿(2)布置材料厚度减小的区域(9,10,13,14)。 所述材料厚度减小的区域可以是具有轴向或径向范围的开口(9,13,14)。 其他措施包括以适当的方式设计齿(2)和间隙(3),并在不同部位形成具有不同特性的制动盘。
