Brake disc for a vehicle disc brake, comprising a radially inner hub portion ( 1 a), intended to be non-rotatably joined to a wheel hub, and a surrounding, radially outer disc portion with opposing friction surfaces. The outer disc portion is formed by two disc elements ( 4 ) joined to the hub portion, and which are separated by spacers ( 7 a -7 f), which define passages for cooling air and of which at least some ( 7 a , 7 b) are in the form of fan vanes to generate an airflow from the passage inlets ( 10 ) at the outer periphery of the disc to the passage outlets ( 11 ) at the outer periphery of the disc. |
