A differential is-made without gears in the satellites and planetaries, in the planetary shafts elliptical tracks are obtained on the fronts and on the circumferences of the shafts, the shape of the tracks is semi-spherical or semi-cylindrical and requires the profile of half spheres or half rollers to roll tangentially within the tracks for a part of their circumference, the balls or rollers being constrained partly in the tracks, partly in the translators and, sometimes, partly in the cylinder and otherwise in the cross that divides the two shafts. The whole is contained by the cylinder in which the longitudinal seats are dedicated to the translators and the spheres that drag the balls or rollers. This cylinder can also be composed of two parts joined at the center to block the cross. In some cases, inside the shafts a bilateral locking and unlocking solenoid (SBL) is installed.

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 device is provided with: an input member; a gear set with output gears to transmit torque from the input member to the output gears while allowing differential motion therebetween; a first clutch for limiting the differential motion; a first pressure pressing on the first clutch; a first cam mechanism for pressing the first pressure plate toward the first clutch; a second clutch, when connected, drivingly connecting the output gears with the input member; a second pressure plate for engaging the second clutch; and a rotatable driver disk including a pressing member so coupled with the cam mechanism as to, from a first position to a second position, rotate the first cam mechanism together and to, from the second position to a third position, allow the first cam mechanism to create rotational difference relative to the pressing member, thereby engaging the second clutch.

A differential gearing device includes a base gearing device and an actuator. The base gearing device including a first gear connected to a first output of the differential gearing device, a second gear connected to a second output of the differential gearing device, differential gearing connected to each of the first gear and the second gear, and a clutch connected between the first gear and the second gear. The actuator actuates the clutch to change a torque bias ratio between the first gear and the second gear.

A differential transmission for transmitting a torque to an axle of a motor vehicle, has at least one driveshaft and at least one output shaft, which are connectable in torque-transmitting manner via a clutch within a housing of the differential transmission, wherein the clutch is actuatable via an actuating device, wherein the actuating device is mounted on the housing, wherein the at least one output shaft is mounted in a rotatable manner via a bearing, wherein the bearing is mounted on the actuating device; wherein a stop is arranged on the at least one output shaft such that an actuating force that is provided for actuating the clutch and acts at least in an axial direction is supported on the stop at least via the actuating device and the bearing.

A mechanical locking differential includes a driving ring in a differential housing between right and left active components. The driving ring is in line with the input bevel gear. The differential housing has a thin wall in a single, integral shell around the driving ring. Several hollow cylindrical shaft pins are used to attached the driving ring to the differential housing, with the shaft pins being driven radially relative to the transverse axis of the differential outputs in an interference fit with the housing and the driving ring. The shaft pins are held from axially backing out by two small rivets. The shaft pins preferably have a threaded inner diameter which assists in removal. The shaft pin attachment allows the bevel gear to extend closer to the transverse axis without obstruction.

A gearless differential for distributing power from a motor to two follower shafts with ends connected to opposite wheels and to opposed outer disks held in position with a journal mounted casing having corresponding identical regular polygonal raceways with asymmetric sections surrounding a central drive disk there between with equidistant radial slots each holding one cylinder or roller bearing to radially reciprocate as they race along the raceways in a slippage mode where one wheel loses traction; and in a drive mode where the central drive disk power input drives both outer disks connected to the two follower shafts transferring torque evenly to both wheels so there is no movement of the cylinders or roller bearings in the raceways.

A differential apparatus includes a differential device, and a differential restricting portion configured to restrict a differential operation of the differential device. The differential device includes a differential case which is rotatably disposed, a differential gear which is rotatable while being supported by the differential case and revolves by rotation of the differential case, and a pair of output gears which are meshed with the differential gear and are rotatable relative to each other. The output gears include a gear member provided with a gear portion, and an output member including an output portion configured to output a driving force inputted to the output gears. A cam portion is provided between the gear member and the output member. The differential restricting portion is provided between the differential case and the output member.
