The cush drive represents a variable-damping mechanical coupling mechanism situated between a rotating hub and sprocket in internal combustion engine drivetrains. Its core principle relies on elastomeric elements with splined engagement to decouple rotational inertia during acceleration and deceleration, thereby attenuating torsional vibration shocks transmitted from the gearbox chain. This device functions within automotive tribology and kinematics by utilizing hysteretic material deformation to smooth power delivery fluctuations inherent in lumpy combustion cycles while reducing structural impact loads on transmission components.
