A driveline power transmitting component with a differential assembly having a differential input, first and second differential outputs, which are driven by the differential input, a first friction clutch, a first biasing spring and a second friction clutch. The first friction clutch has a friction plate that is non-rotatably but axially slidably coupled to the differential input. The first biasing spring urges the first friction clutch into an engaged condition in which the friction plate of the first friction clutch is frictionally engaged to the first differential output. The second friction clutch has a plurality of first clutch plates, which are axially slidably but non-rotatably coupled to the differential input, and a plurality of second clutch plates that interleaved with the first clutch plates and axially slidably but non-rotatably coupled to the first differential output.

A differential device includes: an input member; a case member arranged coaxially with the input member; a one-way clutch arranged between the input member and the case member and transmitting torque therebetween only when the input member attempts to rotate in a normal rotation direction; a pinion gear supported by the case member to rotate about the axis perpendicular to the center axis of the case member; and a pair of side gears supported coaxially with the input member to rotate relative to the input member and the case member and meshing with the pinion gear.

A vehicle has an engine, a limited slip differential (LSD) mounted on an axle driven by the engine, and left and right wheels operably connected to the LSD. At least one parameter indicative of a riding condition of the vehicle is determined. A slippery driving condition is detected based on the at least one parameter. The LSD is selectively locked in response to the detection. The slippery driving condition is detected when a torque requested by a user is above a load line of the engine, upon successive wheel slips occurrences, and/or when a wheel slip is detected while a preload is applied to the LSD.

Disclosed herein are systems, gearing assemblies, and methods for controlling a differential rotation rate between shafts of a vehicle using a variable speed motor. An embodiment includes a gearing assembly including a differential configured to engage a first axle shaft, a second axle shaft, and a drive shaft of a vehicle. The gearing assembly further includes a plurality of adjustment gears configured to engage the differential, configured to be driven by a variable speed motor of the vehicle, and configured to controllably alter a rotation of the first axle shaft relative to the second axle shaft based on rotation produced by the variable speed motor. The plurality of adjustment gears includes a subassembly of planetary gears including a planetary gear carrier, a first set of planetary gears coupled to the planetary gear carrier, and a second set of planetary gears coupled to the planetary gear carrier.

A method of controlling an axle assembly. At least one wheel hub may be operatively connected to a differential assembly having a ring gear when the ring gear does not receive torque from a torque source. Torque from the wheel hub may rotate the ring gear and the ring gear may provide splash lubrication.

Differentials having plate packs for exerting a braking torque onto the output shafts of the gear unit are known. The brake device is intended to be designed such that effective braking can be achieved using it and that it is easy to service. To this end, the invention makes provision for the brake device to be a drum brake having a passive element, exhibiting a cylindrical frictional surface, and brake shoes, the frictional surfaces of which brake shoes can be placed against the cylindrical frictional surface of the passive element. The passive element can be a brake drum or a radial brake disk, the cylindrical edge of which serves as a frictional surface. The passive element is fastened to the differential cage and/or one of the shafts. The brake shoes are held in a pivotable manner on a carrier plate fastened to the outside of the differential housing.
