摘要： An electronically locking differential assembly constructed in accordance to the present disclosure includes a differential casing, a first and second side gear, a lock actuation assembly and a lock detect mechanism. The lock actuation mechanism selectively moves between a locked state where the side gears are fixed for concurrent rotation and an unlocked state where the side gears rotate relative to each other. The lock detect mechanism detects whether the lock actuation mechanism is in the locked, unlocked state, and an intermediate position between the locked and unlocked state; then provides feedback to the driver on the state of the lock actuation mechanism.

摘要： A final drive differentially for distributing torque input into a shaft via a differential device to a pair of axles is provided with a ring gear coupled via gearing to the shaft to transmit the torque to the differential device. A housing unitarily includes a main portion supporting the shaft and enclosing the differential device, and a wall portion including a first opening through which one of the axles passes and supporting a first end of the differential device. A cover included a second opening through which the other of the axles passes, and is combined with the housing to support a second end of the differential device, wherein the wall portion, the ring gear, and the shaft are arranged, from the wall portion toward the cover, in an order of the wall portion, the ring gear, and the shaft.

摘要： An axle assembly with a housing, an annular gear, a bearing, a differential, and a pair of output shafts. The housing has an annular hub. The annular gear is received in the housing. The bearing, which is a four-point angular contact bearing, supports the gear for rotation about an axis relative to the housing and has an inner bearing race, which is mounted on the annular hub, and an outer bearing race that is fixedly coupled to the annular gear. The differential is received in the housing and includes an input member, which is coupled to the annular gear for rotation therewith, and a pair of output members that are rotatable relative to the input member about the output axis. Each of the output shafts is coupled to an associated one of the output members for rotation therewith. One of the output shafts extends through the annular hub.

摘要： A differential assembly including a differential housing, a gear assembly, a shaft, and a ring gear. The differential housing generally includes a peripheral wall, first and second end walls connected to the peripheral wall and spaced apart along a rotational axis so that the peripheral wall and the first and second end walls, in combination, define an internal cavity, a transitional region defined in the differential housing where the second end wall meets the peripheral wall, and a first window formed through the peripheral wall, the transitional region, and/or the second end wall and into the internal cavity, the first window including a central portion and first and second ear portions adjoining the central portion and extending outwardly therefrom. The first window defines a shape when projected perpendicularly onto a first plane including both the rotational axis and a pinion axis, said pinion axis extending perpendicular to the rotational axis.

摘要： A differential apparatus includes a differential unit and a multi-plate clutch. The differential unit includes a differential case, a differential gear and a pair of output gears. The differential case includes a case main body and a cover body to close an opening of the case main body. The opening of the case main body is formed on a side of one of the pair of output gears. The multi-plate clutch is provided only on a side of the opening of the case main body. Outer clutch plates of the multi-plate clutch are engaged with the differential case. Inner clutch plates of the multi-plate clutch are engaged with the one of the pair of the output gears.

摘要： A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.
