RIGID CLUTCH DISCS
FEATURES
Specially tuned cushion deflection
Suited to vehicles with a Dual Mass Flywheel (DMF) as dampening occurs in the flywheel
ADVANTAGES
Simple design
Smooth buildup of torque when used with a DMF
Note: When not used in conjunction with a DMF engagement is sudden and NVH could be an issue as the clutch system has no dampening.
SINGLE-STAGE TORSIONAL DAMPER CLUTCH DISCS
FEATURES
Single-stage torsional damper with custom spring tension
Suited to vehicles with either a single or dual mass flywheel
ADVANTAGE
Reduction of vibration and noise in the powertrain
MULTI-RATE TORSIONAL DAMPER CLUTCH DISC
FEATURES
Multi-stage torsional damper with separated first and second stage dampers
Tuned for low torque low angularity dampening as well has high toque high angularity dampening
Suited for vehicles with a solid mass flywheel or vehicles that have been converted from a dual mass flywheel to a solid mass flywheel
ADVANTAGES
Reduction of vibration and noise in the powertrain
Smooth build up of torque when accelerating
Low vibrations at idle
CLUTCH DISCS AND DUAL MASS FLYWHEELS
|
A DMF is designed to reduce the torsional vibrations in the powertrain therefore generally a clutch disc used in a DMF has no torsional dampeners. If a vehicle is converted from a DMF to a solid mass flywheel the clutch disc is now required to dampen noise and vibrations. This is done by using a multi-rate clutch disc which reduces most of the noise and vibration however in some vehicles higher vibration and noise can be experienced compared to the standard DMF.
