How does the preload spring work in a clutch differential?
Although the preload spring puts some pressure on the plates, more pressure is applied when the engine power/torque is applied to the side gears through the spider gears. When torque is applied to beveled gears, this creates an axial force which tries to force the gears apart.
How does a clutch differential work in a car?
When turning or when one wheel has low traction, the wheel with the most traction has higher turning resistance than the wheel which is slipping. The engine torque applied through the spider gears to the side gear with higher traction (resistance) causes more separating force between the spider gear and side gear.
