Multiplate Clutch

The multiplate clutch comprises an inner drive hub, a clutch basket and a set of drive/reaction plates and friction plates.

The friction plates are located on splines on the input shaft and rotate when the input shaft rotates. The drive/reaction plates are located on splines in the clutch basket which is positively attached to the front drive gear.

The front drive sprocket and clutch basket are located on bearings to allow speed difference relative to the input shaft when no locking torque is applied.

When the vehicle is moving, the following components rotate:

• Front driveshaft
• Front driveshaft output flange
• Output drive gear
• Front drive gear
• Clutch basket.

Torque is not applied to the front driveshaft until the Transfer Case Control Module (TCCM) engages the multiplate clutch. The multiplate clutch is engaged by applying hydraulic pressure to the multiplate clutch piston to clamp the multiplate clutch. This allows the torque to be applied to the front driveshaft. The front drive gear is attached to the front output shaft by the drive chain.
