Salisbury: Ramped cross-pin & clutch packs · Torsen: Helical planet pinions in pocket boresSpiral bevel ring gears, axle side/sun gears, and bearing pillow blocksLeft: Multi-plate friction discs with 45°/60° ramps · Right: Gear-separation pocket friction (3.5:1 TBR)Comparison of two mechanical limited slip differential architectures on an instrumented dynamometer bench. On an open differential, if one wheel encounters ice, torque to both wheels collapses to zero. Left: Salisbury 1.5-way clutch LSD uses a cross-pin that rides up 45° drive ramps, axially separating two pressure rings to compress multi-plate clutch packs against baseline Belleville preload. Right: Torsen Type 2 differential uses crossed-axis helical planet pinions nested in cylindrical housing pockets; drive torque forces the pinions radially against the pocket walls and axially into bronze thrust washers, generating instant mechanical torque biasing (3.5:1 TBR) with zero clutch wear.
