DUAL ENGAGING SILENT CHAIN DRIVE A silent chain (10) for automotive vehicle or industrial drive applications wherein the chain is formed of blocks (11) of links (12) alternating with pairs of guide links (13) joined by pivot pins (14,14') wherein both teeth (23,23') of each link are in driving engagement with the teeth (32,33,34 etc.) of the driving sprocket (31) with alternating inside flank (25) and outside flank (24') engagement. The pins joining the guide links (13) and blocks (11) of links lie on the approximate pitch diameter (45) of the sprocket. Each link has the inside flank (25 or 25') defined by a compound curve (27 or 27') with one radius (?) centered in an aperture center (x or y) for the link. |
