The present invention relates to a technology in which a transition between a medium-torque transmission state and a high-torque transmission state by a limited slip differential is continuously performed during a driving process of a vehicle. The present invention introduces a limited slip differential configured to comprise: an input shaft constantly connected to a differential case of a slip differential; an output shaft selectively connected to the input shaft via a clutch pack and constantly connected to a wheel; a medium-torque transmission means for pressing a clutch plate coupled to the input shaft to press-fit the clutch pack; and a high-torque transmission means selectively engaged with the clutch plate by moving a hub coupled to the output shaft in a state where the input shaft and the output shaft are synchronized as the clutch pack is fastened, and a controlling method therefor.

A power divider unit including an input shaft, a drive gear disposed around the input shaft, an inter-axle differential assembly coupled to the input shaft, an output side gear coupled to the input shaft, and a locking system for the power divider unit. The locking system is configured to passively lock the inter-axle differential assembly. The locking system includes a ramped first clutch member in selective engagement with the drive gear, a mating second clutch member configured to engage the first clutch member, a clutch pinion, and a slip clutch assembly. The second clutch member and the first clutch member rotate at different speeds, the clutch pinion rotates and causes the slip clutch assembly and second clutch member to rotate at a speed of the input shaft, causing the first clutch member to mate with the first clutch member.
