Abstract
Shaft braking disc with a unitary, ventilated friction ring (3), provided with ventilation ribs (4) some of which have radially inwardly extending support spokes (2) terminating in a hub (1) and having a cross section area which gradually diminishes in the radially inward direction. Attached to both sides of these spokes in the circumferential direction are reinforcement ribs (7) whose cross sectional areas gradually increase in the radially inward direction, in such manner that the sum of the cross sections of a support spoke (2) and its reinforcement ribs on both sides is at least substantially constant over the entire radial length of the spoke.
