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.

A downsized torque vectoring device that is easily to be mounted on an automobile. The torque vectoring device comprises: a differential mechanism that allows a first driveshaft and second driveshaft to rotate at different speeds; an actuator that applies a control torque to the differential mechanism to rotate the first driveshaft and the second driveshaft at different speeds; and a reversing mechanism that allows the first driveshaft and the second driveshaft to rotate in opposite directions. A gear ratio of a first gear train and a gear ratio of the second gear train are different from each other.

A final drive for a motor vehicle, including a first input shaft, a second input shaft, a first output shaft, and a second output shaft, wherein the first input shaft is permanently coupled to the first output shaft by a first bevel-gear transmission and the second input shaft is permanently coupled to the second output shaft by a second bevel-gear transmission. The first input shaft and the second input shaft are arranged coaxial to each other and the first output shaft and the second output shaft extend from the respective bevel-gear in opposite directions.

Disclosed herein are various robotic surgical devices and systems that include first and second elongate bodies, first and second driveshafts disposed through the second elongate body, and an in-line shoulder joint with a robotic arm coupled thereto. In certain implementations, the in-line shoulder joint has a differential yoke and a dual shaft disposed within the yoke lumen.

A disconnect including: an input hub; an output race including a radially inner surface with ramps; wedge plate segments radially disposed between the input hub and the output race, each segment including a ramp in contact with an outer race ramp; an actuator cage; and an actuator plate. For a connect mode, the input hub, the wedge segments, and the output race transmit torque from an electric motor of an electrically-powered vehicle to a wheel of the vehicle. In a disconnect mode, relative rotation between the input hub and the output race is enabled. To transition from the connect mode to the disconnect mode: the actuator plate is displaced by an actuator; the actuator plate axially displaces the actuator cage; and the actuator cage circumferentially displaces the wedge plate segments to decrease or break frictional contact between the wedge plate segments and the input hub.

Disclosed is a locking differential assembly which includes a differential case, a first output shaft and a second output shaft. Further included is a first side gear non-rotatably coupled to the first output shaft and a second side gear non-rotatably coupled to the second output shaft. A differential pin is also included, the differential pin having differential gears. The differential gears are rotatably supported by the differential case and drivingly engaged with the first and second side gears to allow differential rotation thereof. Also included is a locking mechanism, the locking mechanism being actuated when a first torque force is applied to a drive cam and a driven cam. Finally included is an electromagnetic coil. The electromagnetic coil actuates a brake plate, the brake plate comes into frictional with a brake disc. Furthermore the electromagnetic coil is discontinuous around the circumference of the brake disc.

A pinion shaft assembly facilitates assembly of an automotive differential. An angular contact double row ball bearing is assembled to an outer surface of a hollow pinion shaft. An axial pre-load is established and maintained by orbitally forming an outwardly turned portion of the hollow pinion shaft. In some embodiments, the two inner rings are assembled to the pinion shaft. In other embodiments, a raceway may be formed directly on an outer surface of the pinion shaft to eliminate one of the inner rings. The pinion shaft includes a spline, such as an axial spline or a face spline, for fixation to a driveshaft.

A differential assembly provided with a power distribution unit includes a first housing, an output shaft, a shaft, and a torque limiter. The first housing defines a biasing member bore and a brake bore. The output shaft extends at least partially through the first housing. The shaft is disposed about the output shaft and extends between a first shaft end that is connected to a differential unit and a second shaft end. The torque limiter is disposed within the first housing and is arranged to selectively inhibit rotation of at least one of the output shaft and the shaft.
