Abstract

An assembled vehicle brake disk has a basically rotationally symmetrical friction ring which is fastened by way of several linking points in a rigid or floating manner to a basically rotationally symmetrical hub part. At least two distances between respectively adjacent linking points, which distances follow one another in the circumferential direction, differ from one another, in which case, viewed in their entirety, the linking points are arranged in a non-uniformly distributed manner along the circumference. Preferably, an uneven number of linking points are provided which may be arranged to be very asymmetrically distributed along the circumference. The number of linking points may be in the order of between 5 and 15, a smaller number being provided per circumferential segment with respect to lower-frequency noise radiations, and a higher number being provided with respect to higher-frequency noise radiations.
