<p>A crankshaft decoupler (10) has a mounting hub (12), a pulley (14) rotatably mounted on the mounting hub (12), an annular carrier (26) mounted within said pulley (14), a biasing device (38) mounted therebetween, and a one way clutch (40) mounted between the annular carrier (26) and the pulley (14). The biasing device (38) cushions the belt drive from crankshaft impulses and lowers the angular resonant frequency of the belt system. The one way clutch (40) prevents sudden reversal of the belt tension in the drive due to start/stop of the engine or sudden deceleration of the engine and prevents momentary reverse slip belt squeal as a result of the tensioners' inadequate output for the reverse mode. The one way clutch (40) limits the maximum amount of torque which may be transmitted preventing belt slippage during momentary overload.</p> |
