FIELD: transport.
SUBSTANCE: invention relates to transport engineering. Proposed brake disc comprises friction ring screwed to the hub. Screws penetrate through clamp ring that makes a counter support for screws and abuts on connection flange arranged at friction ring inner circle. Clamp ring and hub can be engaged with geometrical closure. Opposite sides of the hub and clamp ring are provided with appropriate ledges and recesses. Clamp ring stays in friction abutment on friction ring.
EFFECT: higher reliability.
