A differentia may include a metal plate interlocking with a pinion, and at least one permanent magnet fixable to a case of the differential to generate an eddy current in the metal plate upon a relative rotation of the metal plate.

To maintain smooth rotation of a pinion gear, a differential device includes: a differential case including a case main body and a bearing boss protruding from the case main body and rotatably supported about a first rotation axis; a side gear; and a pinion gear. An introduction groove for introducing lubricating oil into the case main body is formed on the bearing boss. An inner surface groove communicating with the introduction groove and extending toward the pinion gear is formed on the case main body. The inner surface groove includes a first groove portion and a second groove portion positioned radially outward from the first groove portion in the radial direction. The shape of at least a part of the first groove portion is a shape over which the lubricating oil is hard to climb during vehicle forward movement as compared with the shape of the second groove portion.

In a differential device, a differential casing is formed of lightweight alloy, and gears are formed of steel. A plurality of screw hole bosses each including a screw hole to which each of a plurality of bolts is fastened to fasten a ring gear, and a first rib integrally coupling the screw hole bosses together are protrudingly provided at the side face of a flange. A plurality of second ribs integrally coupling the screw hole bosses and a first bearing boss together is provided on the external side face of a differential casing. A first thickened portion including a first gear support portion that supports the back surface of a pinion gear is formed on the circumferential wall of a differential casing body. A second thickened portion that includes a second gear support portion which supports the back surface of a side gear is formed on the first bearing boss.

A turbine engine includes a core engine including a first spool and a second spool rotatable about a main engine longitudinal axis, a boost spool powered by a secondary drive system, and an accessory gearbox coupled to the core engine and the boost spool. A differential gear system is coupled between the core engine, the boost spool and the accessory gearbox for distributing power between the boost spool, the core engine and the accessory gearbox.

The description is directed broadly to a locking differential, comprising; a pair of rotating bevel gears engaged with one another via at least one pinion gear rotatably supported within a carrier; a locking member disposed within the carrier and engagable with each of the bevel gears, the locking member being movable between a locked configuration and an unlocked configuration, such that in the unlocked configuration the locking member allows free rotation of the bevel gears in engagement with the at least one pinion gear to equalise torque between a first bevel gear and a second bevel gear of the pair, and in the locked configuration the locking member locks the first bevel gear to the carrier and locks the second bevel gear to the carrier, simultaneously, to prevent relative movement therebetween.

A differential with a washer for a gear in a differential housing includes an outer edge at a maximum radial distance from an axis, and an inner edge defining an opening, the inner edge defined in part by an innermost portion at a minimum radial distance from the axis and the inner edge having an outward portion spaced radially outwardly from the innermost portion. The washer also includes an axially and radially inclined sidewall extending at least part of the way between the outer edge and the innermost portion.

In a differential device including a pair of side gears, a plurality of pinion gears and a pinion shaft, the pinion shaft includes a plurality of shaft parts rotatably fitted to and supporting the plurality of pinion gears respectively, and an annular support part linking the plurality of shaft parts to each other, an annular recess portion is formed in an inner peripheral face of the support part, the pinion shaft has an oil guide part that guides lubricating oil within the recess portion to a part where the shaft part and the pinion gear are fitted together, and an inner end portion of at least one of the side gears protrudes into an inner space of the support part and is positioned within a width of the recess portion in an axial direction of the rotating shaft.

A vehicle axle assembly includes an axle housing and a carrier assembly. The carrier assembly includes a carrier housing and a differential assembly that includes a ring gear arranged in meshing engagement with a pinion gear. The gears are urged away from one another by separation forces during torque transfer. The carrier housing includes a curved wall circumscribed by a mounting flange as well as a plurality of integrally formed and parallel spaced apart gussets interconnecting the curved wall and the mounting flange. The gussets extend in a direction parallel to the gear separation forces to resist bending of the carrier housing. Other features increasing the structural rigidity of the one-piece carrier housing are discussed.

A differential gear assembly for a vehicle includes: an annular ring gear having internal and external surfaces, and rotates around a rotational axis extending in an axial direction; first and second side gears respectively distribute a first and second output torque to first and second drive shafts; first and second differential pinion gears respectively engage the first and second side gears; a pinion pin extends diametrically across the ring gear, where the first and second differential pinion gears are rotatably arranged on the pinion pin. The ring gear comprises first and second slots for receiving the pinion pin, where the slots are arranged in connection to the internal surface and extend partly through the ring gear in the axial direction.

A method for mitigating torque steer in a vehicle having a steering axle with a limited slip differential and a pair of output members. The limited slip differential includes a pair of differential outputs and a clutch. The method includes: operating the limited slip differential with the clutch in the first condition; determining that the vehicle is in a state in which a torque steer condition is occurring or is likely to occur; and operating the clutch to reduce a torque differential between the differential outputs to mitigate the torque steer condition. A vehicle with a steering axle and a controller that is configured to operate a clutch in the steering axle to attenuate torque steer is also provided.
