Abstract

A braking device for a vehicle unusually capable of determining a high heat exchange efficiency may have a disc brake disc with a braking band. The braking band may have two opposite plates. The plates are connected to each other by pins which delimit a ventilation duct with the plates. The disc brake also has a driving bell adapted to connect to a stub axle of a vehicle. In ventilation duct there is at least one radial connection extension which connects the two opposite plates and connects the braking band to the driving bell so that the braking band and the driving bell are in one piece. The at least one radial connecting extension faces with a portion thereof and on both of its circumferentially directed sides on two axial through windows, which are through openings directed in an axial direction and which both communicate with said ventilation duct.
