Abstract
A friction disc () for a torque and/or rotational control apparatus includes elongated and shortened fins () upstanding between and equally circumferentially spaced intermediate first and second component discs (). The fins () are free of circumferential interconnections to allow air to radially pass freely between the fins (). The fins () extend in non-radial directions between the first and second component discs (). A mounting ring () is integrally formed with the elongated fins () intermediate and axially spaced from each component disc () and radially inward of the inner edges () of the component discs (). The elongated fins () each includes a first elongated portion () and a second shortened portion () extending at an obtuse angle therefrom and on the mounting ring () radially inside of the inner edges (). Windows () are formed in the mounting ring () radially inside of the component discs () and of the elongated fins ().
