A brake disc with improved ventilation cooling means, comprising a brake ring, the interior of which is provided with radially running channels formed by vanes. Cooling air to be conveyed by the vanes enters the channels on the hub side at the inner circumference of the brake ring and exits at the outer circumference of the brake ring. In addition to rib-shaped vanes, the length of which correspond to the entire width of the brake ring, thermal flow vanes are provided. To increase the air turbulence, the width of the base of the thermal flow vanes is more than 60% of the distance from the start of one vane to the start of the next vane, measured along the braking radius, and the width of the base of the thermal flow vanes is between 80 and 100% of the distance between vanes, measured at the inner circumference of the brake ring. Moreover, the thermal flow vanes have recesses and, to increase the air throughput, a ratio of air intake cross section to air exit cross section of less than 1:2 up to at most 1:1 is maintained.

Brake disc with improved ventilation cooling

A hub unit is adapted to be connected to a vehicle wheel or axle for rotation therewith. A circular brake ring unit surrounds the hub unit and is divided into at least two parts located at opposite sides of the axis of the circular brake ring unit. Connecting elements dismountably mount the brake ring unit on the hub unit by releasably connecting together the two or more parts of the brake ring unit, whereby to permit separation of the parts of the brake ring unit to facilitate dismounting of the brake ring unit from the hub unit.
