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 differential gear with an input side that can be rotated about an axis of rotation, which has a rotary drive contour for the rotary drive engagement with a drive wheel and at least one pinion gear that can be rotated about a pinion axle, and an output side that can be rotated about the axis of rotation, which has a first axle wheel and a second axle wheel which are in rotary drive engagement with the at least one pinion gear, wherein the input side has a rotary drive section on which the rotary drive contour is provided, and a support section on which the at least one pinion gear is arranged. The rotary drive section and the support section can optionally be brought into a rotary drive connection with one another by means of a shiftable pawl freewheel.

A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

An overrunning clutch (ORC) differential is provided that includes a locking mechanism that is configured to lock rotation of a clutch cam housing to a roller cage to retain a centering of each roller in an associated cam roller feature to prevent torque from being communicated between the clutch cam housing and first and second hubs when the locking mechanism is activated.

An on-demand four-wheel drive system includes a differential for the rear axle, a differential for the front axle, and a center differential connecting to the front and rear axle differentials. All three of the differentials contain a bi-directional overrunning roller clutch to enable locking of their respective outputs. The clutches provide a superior on-demand four-wheel drive system that distributes power to each drive wheel to propel the vehicle.

A differential capable of automatically restricting a differential ratio and increasing torque comprises a container. A differential housing is provided in the container. The differential housing is internally provided with a planetary gear, a planetary shaft, a left half axle gear, and a right half axle gear. The planetary gear is provided on the planetary shaft, and the planetary gear engages with the left half axle gear and the right half axle gear, respectively. The differential housing comprises a left housing and a right housing engaging with each other. A ring gear is provided at the outer circumference of an end of the left housing engaging with the right housing, and a bevel ring gear is provided at the outer circumference of an end of the right housing engaging with the left housing.

A differential gear for a motor vehicle, comprising an outer housing, the outer housing being drive-connected to an input element, an inner housing, the inner housing being mounted rotatably at least partially within the outer housing, at least two compensating elements and at least two output elements, the compensating elements and the output elements being enclosed at least partially by the inner housing, and the inner housing being drive-connected to the output elements via the compensating elements, and also at least one switching unit, the switching unit being arranged on the inner housing in such a way that, starting from a freewheeling position, it can selectively be drive-connected to the outer housing or to the outer housing and one of the two output elements.

A damping system includes a flywheel motor device, a generator device, a flywheel power storage device and a power coupler device. When mechanical power generated by the flywheel motor device increases or remains constant, the power coupler device couples the mechanical power generated by the flywheel motor device to the generator device and the flywheel power storage device. When mechanical power generated by the flywheel motor device decreases, the power coupler device couples the mechanical power generated by the flywheel motor device and mechanical power outputted by the flywheel power storage device to the generator device.
