Classification: CPC F | IPC F

Claim 0:
1. A limited-slip differential system comprising:
a housing configured to partially receive a drive shaft, a first axle, and a second axle;
a differential carrier disposed within the housing, the differential carrier being rotatable relative to the housing, the differential carrier including:
a first carrier portion, and
a second carrier portion selectively connected to the first carrier portion;

a differential at least partially carried by the differential carrier, the differential being operatively connectable to the drive shaft, to the first axle, and to the second axle, the differential being configured to distribute torque from the drive shaft to the first and second axles in accordance with a speed difference between the first and second axles that is sensed by the limited-slip differential system;
a clutch pack including a first plurality of clutch plates rotationally fixedly connected to at least one of the first and second carrier portions, and a second plurality of clutch plates rotationally fixedly connected to a hub member fixedly connectable to one of the first and second axles, the clutch plates of the first and second pluralities of clutch plates being sequentially placed relative to one another;
a pressure system configured to selectively exert an axial force on the clutch pack for selectively causing frictional engagement of the clutch plates of the first and second plurality of clutch plates with one another,
at least one of the first and second carrier portions at least partially defining at least one lubrication channel extending at least partially radially, the at least one lubrication channel fluidly connecting an exterior of the differential carrier to an interior thereof for lubricating at least two clutch plates of the clutch pack, the at least one lubrication channel being arcuate such that a radially inner end of the at least one lubrication channel is circumferentially offset from a radially outer end of the at least one lubrication channel, and the at least one lubrication channel being axially aligned with the at least two clutch plates for guiding lubricant from the exterior of the differential carrier to radial edges of the at least two clutch plates.
