The invention relates to the attachment of brake discs to the wheels of rail vehicles having at least one brake disc belt which is fastened to the side of the wheel by means of fastening elements fixed to the second part (wheel or brake disc belt) and to the second part (brake disc belt or wheel). by means of parallel cams, each fastening element comprising two radially axially parallel surfaces between which the cam is clamped, and wherein the two axial cover parallel surfaces form part of a box-like opening in the frame, in which frame the cam is located with radial clearance, according to U.S. Pat. No. 2585/71) · Such a wheel, which is the subject of the main patent mo 56 798 (patent application 2585/71), is lighter and simpler to manufacture than other wheels; the belt expands due to heating during braking.

To prevent uneven weight between the pre-assembled wheel and the brake disc belt, the sickle-like substance has hitherto been removed from the wheel or rim of the wheel. The disadvantage here is not only the greatness of this way of preventing the imbalance, but also the fact that when the new imbalance subsequently occurred, the sickle-like removal points of the substance remained and could only be smoothed by means of a new, sickle-like removal point.

The object of the present invention is to provide a wheel such as the one mentioned above, in connection with which the imbalance found can be more easily compensated.

This object is solved according to the invention in the case of such a wheel in that the cams or frames are fastened to the wheel by means of screw bolts between the wheel ring or rim and the brake disc belt and that the compensating weights fitted in the annular gap between the wheel ring or rim and the brake disc are

Since the weights are placed at a relatively large distance from the wheel hub, they are located quite advantageously in terms of the desired effect, i.e. the smoothing of the imbalance. It is not necessary to use additional means to attach the compensating weights to the tire gap, as screw bolts are usually used to secure the brake disc belt anyway. It is a further advantage of the invention that the different compensating weights available make it possible to compensate for a given imbalance very quickly and accurately. If the imbalance shifts after a certain period of use, the new imbalance can be easily compensated by removing the previous compensating weight and replacing it at another point with a new, possibly heavier or lighter compensating weight.

A particularly simple and convenient embodiment of the compensating weight consists of a printing piece and a mounting plate with a bore.

The invention will now be described in more detail with the aid of an exemplary embodiment and with reference to the drawings, in which FIG. 1 shows a plan view of a part of a rail wheel in the area of a wheel tire, FIG. 2 shows a cross-sectional view of the subject of Fig. 1 along arrow A-A; and fig. 3 shows a cross-sectional view of Figure 1 the arrow X direction.

The part shown in the drawing of the rail ring 14 has an annular cavity 13 inside it · An axial screw bolt 13 »passes through the wheel ring 14 in the region of the cavity 13 which holds the segmental fastening part 16. The fastening part 16 is used for fastening the brake disc belt 18. not shown in the drawing, each of which is clamped between two radial, axial clamping surfaces of the frame-shaped mounting portion 16. The cams of the brake disc belt 18 are so long that they extend through the mounting parts 16 and are against the wheel disc.

In the region of the cavity 13, the non-concave portion of the wheel ring 14 and the brake disc belt 18 form an annular gap. A leveling weight consisting of a pressure piece 31 and a mounting plate 32 with a bore is placed in this ring gap. The leveling weight 31,32 is fixed at its mounting plate 32 together with the mounting parts 16 by means of a screw bolt 13.

Since the leveling weight 31,32 is placed in the annular gap formed by the brake disc belt 18 and the wheel ring 14 and because it is fixed with a screw bolt 13, the leveling weight 31,32 can be quickly and conveniently placed on the wheel and replaced. As a result, balancing has been made substantially easier by the invention.

The invention is not only feasible with the one-piece rail wheel described above, but also with the multi-piece wheel consisting of a rim and a wheel rim mounted on it. In such an embodiment, the non-concave portion of the wheel ring 14 corresponds to the circumference of the wheel and the portion of the wheel ring 14 in the region of the cavity 13 corresponds to the outer region of the rim.
