Differential Clutch Pack Lock Plates for Shorter Bearing Span

The clutch pack is segmented into multiple thin clutch discs stacked in an axially compact arrangement. Each disc contributes to torque capacity while the segmented structure allows efficient space utilization, achieving high torque capacity with reduced axial length and bearing span compared to conventional designs.

The invention transitions from a radial expansion approach to an axial stacking approach by arranging clutch discs in a compact axial configuration. This dimensional reorganization allows multiple discs to be packed efficiently within a reduced axial envelope, decreasing bearing span while maintaining the required number of discs for torque capacity and smooth locking.

The clutch discs are designed with optimized local characteristics including friction material properties, disc thickness variations, and surface treatments. This local quality optimization ensures that each disc contributes maximally to torque transmission, allowing the required torque capacity to be achieved with fewer discs or in a more compact axial arrangement, thereby reducing bearing span.

The invention employs parameter changes such as varying disc thickness, adjusting friction coefficients through material selection, and modifying engagement pressures. These parameter optimizations enable the clutch pack to achieve the required torque capacity and smooth locking characteristics with a reduced number of discs or in a compact configuration, thus decreasing bearing span while maintaining performance.
