Self-ventilated brake disc

摘要

Self-ventilated brake disk, particularly for vehicles, comprising a unique body formed by a frictional circular crown and a hub transmitting the couple to the whole disk, wherein the circular crown includes multiple grooves arranged radially in respect to the center of the disk, including at least a portion with a predetermined width arranged between each of the grooves, said portions been arranged on the same plane that the rest of the circular crown. In this way, the wear of the brake pad is reduced, having a simple construction and providing good heat dissipation during the contact of the brake pad and the friction surface of the disk.

1. Self-ventilated brake disk, particularly for vehicles, comprising a body including a frictional circular crown and a hub, wherein the circular crown includes multiple grooves having a depth arranged radially in respect to the centre of the disk, the crown having a thickness greater than the depth of the grooves, and two opposed faces, the brake disk comprising a bridge portion having a thickness smaller than the groove depth and a predetermined width, said bridge portion being arranged in each of the grooves and having a outer surface in the same plane as one of the two opposed faces of the rest of the circular crown, wherein each bridge portion on one of the two opposed faces is disposed to be aligned with an empty space on the other of the two opposed faces; and
wherein each of the bridge portions arranged in each of the grooves defines at least one continuous circular path.
