03 DRIVELINE/AXLEDifferentialSuper-LSD Outline• The super-LSD is a torque-sensing type that provides improved driving stabilitydue to the following characteristics:— Low torque bias ratio provides improved controllability (torque bias ratio: 2.0)— Creation of initial torque provides improved starting from a standstill andacceleration/deceleration response, and driving straight-ahead (initial torque: 49N·∙m [5.0 kgf·∙m, 36 ft·∙lbf])— Simplifi ed construction provides weight reduction• The gear case component of the super-LSD cannot be disassembled.Super-LSD Construction• Inside the super-LSD, taper rings that are fi xed to the differential gear case havebeen placed between the differential gear case and the side gears. Additionally, acone is provided around the outer surface of the side gear.• Springs and retainers are positioned between the right and left side gears toprovide initial torque to the taper rings.Mazda Technical TrainingMX-5 Miata New Model TrainingSG-117
