Limited Slip Differential
SMCS - 3263 The limited slip differential combines standard differential components with a special multi-disc clutch arrangement. The limited slip differential is designed to provide equal power to both wheels until the ground conditions cause a difference in traction between the left wheel and the right wheel. The limited slipdifferential transfers power from the wheel with the least traction to the wheel with the most traction. The limited slip differential is a direct replacement for the standard differential. The limited slip differential is available in both the front axle group and the rear axle group.

When the wheels have equal traction, the limited slip differential sends an equal amount of power to both of the wheels. This is similar to the function of the standard differential. One wheel begins to turn fasterthan the other wheel if there is a loss of traction. When this occurs, the internal forces that are present between shaft (8) and actuator housings (4) will react on 45 degree angle (9). The internal forces push actuator housings (4) against clutch packs (3). The torque of the clutch pack limits the loss of traction to the wheel that is turning faster. The limited loss of traction is due to theinternal friction of the differential. This effect is produced by two clutch packs (3) which are arranged symmetrically in the differential housing. In a standard differential, one wheel can be held in position when the engine is running and a gear is engaged. The other wheel will turn faster. In the limited slip differential, the above procedure would be more difficult because of clutch packs (3). Theabove procedure will become more difficult as power increases. The limited slip differential is identical on the left side and the right side of two pinion shafts (8). The limited slip differential contains the following components: two thrust washers (2), two clutch packs (3), two actuator housings (4), two bevel gears (5) and four pinion gears (7) . The inside splines of side gears (5) areconnected to the sun gears for the final drives. The outside splines of side gears (5) are meshed with the inner friction discs in clutch packs (3). The side gears send the power through the sun gears and to the final drives.

Housing (1) is fastened to the bevel gear. Housing (1) has inner grooves which hold the outer discs. The outer discs are in clutch pack (3). The clutch pack also has inner discs between the outer discs. The inner discs are splined to the side gears. Actuator housings (4) also fit in the same grooves. The actuator housings are held with the discs from moving radially. Side gears (5)...
