<p>A brake disk for high strain applicable particularly in rail vehicles, which brake disk rotates around its axis (Z) and consists of a hub (1) provided with a bearing plate (2). Said bearing plate (2) is provided with shaped cuts regularly repeated around the break disk circumference, preferably at least three, whereby, each of the cuts consists both of a joining region in the range of a first circumferential angle (U1) and of a flexible elastic region in the range of a second circumferential angle (U2) whereby, the remaining part in the region of a third circumferential angle (U3) form a strength providing region of the bearing plate (2). Each shaped cut has a section between two points (B,C) of the flexible elastic part, which section is exactly defined and formed by a polynomial of the third grade.</p> |
