    • A processing arrangement for a brake element for a vehicle employs a rotational support, such as a precision collet arrangement, for supporting the brake element rotatably about a fixed axis of rotation. The brake element and the spindle are rotated by a drive arrangement that causes the brake element to rotate about the axis of rotation while a rotary encoder that is coupled to the drive arrangement produces a rotation data signal containing rotational information responsive to the rotation of the brake element. Residual unbalances are measured by the production of an unbalance data signal that is responsive to forces that are themselves responsive to a residual unbalance of the brake element. In addition, a surface dimension detector produces a surface dimension data electrical signal that is responsive to a dimensional characteristic of a surface of the brake element. A surface defect detector that typically is in the form of an eddy current probe, produces a surface defect data electrical signal responsive to the presence of a predetermined surface defect of the brake element. The various data signals are correlated in a signal processor to produce rotationally a correlated signal responsive to the rotation data signal, the unbalance data electrical signal, the surface dimension data signal, and the surface defect data electrical signal. Data corresponding to the residual unbalance, the dimensions, and the surface condition of the brake element is presented on a computer monitor and can be stored for quality control purposes and for use in other automated systems, such unbalance correction equipment.
    • 用于车辆的制动元件的处理装置采用诸如精密夹头装置的旋转支撑件,以围绕固定的旋转轴线可旋转地支撑制动元件。 制动元件和主轴通过驱动装置旋转,该驱动装置使制动元件围绕旋转轴线旋转,而耦合到驱动装置的旋转编码器产生包含响应于制动器的旋转的旋转信息的旋转数据信号 元件。 残余不平衡通过产生响应于本身对制动元件的残余不平衡的响应的不平衡数据信号来测量。 此外,表面尺寸检测器产生响应于制动元件的表面的尺寸特性的表面尺寸数据电信号。 通常为涡流探针形式的表面缺陷检测器响应于制动元件的预定表面缺陷的存在而产生表面缺陷数据电信号。 各种数据信号在信号处理器中相关,以响应于旋转数据信号,不平衡数据电信号,表面尺寸数据信号和表面缺陷数据电信号旋转产生相关信号。 对应于制动元件的残余不平衡,尺寸和表面状况的数据呈现在计算机监视器上,并且可以存储以用于质量控制目的,并用于其他自动化系统,例如不平衡校正设备。
