FIELD: transport.SUBSTANCE: invention refers to the transport machine-building industry, and namely to ventilated disk brake devices. A rotor of a brake disk has the shape of a cylindrical plate with the annular geometry and with a circular symmetry axis for its outside circumference and its inside circumference and has the central hole symmetrical with regard to the axis. The rotor has two parallel ring-shaped disks that are connected to each other by means of repeated rows of ribs. The rotor design of the brake disk is symmetrical with regard to different rotation directions of the brake disk, i.e. symmetrical in a plane passing through the rotation axis of the brake disk and one radius of the cylindrical brake disk. At least 50% of the ribs have an elliptical shape, besides, there is at least one rib having a rounded triangular shape, besides, one of the rounded angles is directed towards the outer circumference of the brake disk, and the side opposite to this angle of the rounded triangle is concave.EFFECT: improving heat transfer efficiency and homogeneous distribution of temperature along the brake disk rotor surface, as well as a possibility of using the brake disk rotor both for the left and the right side of the automobile or another transport vehicle.9 cl, 5 dwg, 2 tbl |
