Valeoscope - Transmission Syst. Clutch KIT4P Conversion Kit

6. KIT4P design: Long Travel Damper (L.T.D.)

The L.T.D. technology consists of a specific friction plate with a high damper capacity and a damper with very low stiffness for improved filtration and transmission performance. This low angular stiffness coupled with the specifically matched flywheel inertia ensures the appropriate damping level as well as an extended life of the clutch kit.

Current Valeo O.E. Long Travel Damper techno- logy can be found in three product categories; SX, WX and High Angular Displacement Techno- logy (NX1…NX4). The design depends on the maximum torque of the vehicle engine and on the diameter of the clutch. A majority of the KIT4P range features a WX damper. On certain applications such as Ford Transit, an SX damper is used. The H.A.D. technology is used only in O.E. currently. This will enable Valeo to develop further KIT4P versions for vehicles with higher torques on the I.A.M.
