Abstract
A brake ring for brake disks, especially disk brakes for rail vehicles, consisting of two annular bodies (2, 3) arranged adjacently at a distance from each other, having stud bolts (7) bridging the distance and rigidly connected with the annular bodies (2, 3). These stud bolts are so arranged, for the purpose of the most even distribution possible, that their axes (8) extend through the intersecting points of three systems of straight lines (9, 10 and 11) extending in one radial plane. The straight lines of the first system (9) are parallel and are at an equal distance from each other, the second system of straight lines (10) is formed by a rotation by 60.degree. and the third system of straight lines is formed by a rotation by 120.degree. of the first system of straight lines (9). Preferably, the ratio of the distance (A) of the stud bolt axes (8) and the diameter (D) of the stud bolts (7) is approximately 1.7. The brake ring has only minor aeration losses but high heat transmission by cooling air. When the brake ring heats up, the stresses within the annular bodies (2, 3) and the stud bolts (7) are evenly distributed, and the risk of fracture is reduced.
