ABSTRACT:
A torsional vibration absorbing device for a transmission, such as manual shift automotive transmission, wherein a friction clutch is provided on the output shaft within the transmission. One set of springs apply a constant resilient force to the friction clutch. Interengaging cam plates are caused to separate axially by increases in torque transmitted and another set of springs impose an additional resilient force on the friction clutch to reduce slippage upon such separation. The cams on the cam plates have helically shaped surfaces for full face-to-face contact and the slopes of the surfaces are different for forward or reverse drive therethrough to provide different slippage characteristics for acceleration and deceleration.
