An electronically triggered locking differential includes a differential case, at least one pinion gear and a pair of side gears. A clutch pack is disposed between one of the side gears and the differential case and retards relative rotation between the differential case and the side gear. A cam member is disposed adjacent the clutch pack so that the clutch pack engages when the cam member ramps up. An engagement shaft has one end engaged with the cam member and an opposite end extending through the differential case and engaged with a sprocket. A magnetic coil and flux conductor magnetically couple the sprocket to the differential case when the coil is energized. This coupling retards rotation of the engagement shaft and the cam member relative to the gear case, initiating engagement of the clutch pack to lock the differential.

A cam member for a vehicle differential includes a cam surface made of a high-durability alloy and a clutch surface made of a high-density magnetic alloy. The cam surface and the clutch surface can either be formed into a single component or as separate components that are mechanically coupled together. In one aspect, both the high-durability alloy and the high-density magnetic alloy are powdered metal alloys. As a result, the cam member has different surfaces with optimized characteristics that would ordinarily be difficult to incorporate into a single component.

A hydraulic coupling for use in a vehicle drive train having a fluid path which extends between the housing of the hydraulic coupling and a coupling mechanism. The fluid path includes a first aperture formed in the housing with a first diameter and a longitudinal axis, as well as a second aperture formed in the coupling mechanism. A rigid conduit extends between the first and second apertures with a first portion having a diameter that is less than the first diameter of the first aperture so as to define an adjustment gap that allows the rigid conduit to move out of alignment with the longitudinal axis in response to misalignment between the first and second apertures. In addition, the rigid conduit provides resistance to torque imposed upon the coupling mechanism.

A electric locker differential assembly includes a first and second side gear. A pinion gear set is disposed between the first side gear and the second side gears. An engagement shaft includes flyweights disposed on the engagement shaft which are moveable between retracted and extended positions to lock and unlock the differential assembly. A lockout shaft includes a pawl disposed thereon. An electrical adjustment mechanism includes an actuator operably connected with an adjustment nut or rod. An electrical adjustment biasing spring includes a first leg retained by the adjustment nut and a second leg connected with the pawl wherein movement of the adjustment nut by the actuator varies a biasing force applied to the pawl.

A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing having a manifold housing portion and an accumulator housing portion. The accumulator housing portion and manifold housing portion cooperate to form an accumulator chamber that houses the biasing assembly and the piston. A motor is disposed on a first side of the manifold housing portion, and a pump is disposed on a second side of the manifold portion, opposite the first side. The pump is configured to pump fluid into the accumulator chamber of the accumulator housing portion. A reservoir is defined by at least one of the manifold housing portion and the accumulator housing portion, and a bag filter disposed in the reservoir is configured to filter fluid flowing through the reservoir.

A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a motor and a pump. The hydraulic control unit housing has a manifold housing portion and an accumulator housing portion. The manifold housing portion defines a fluid pathway arrangement for communicating fluid along at least a first fluid pathway. The accumulator housing portion houses an accumulator assembly having a biasing assembly and a piston. The accumulator housing portion and manifold housing portion cooperate to form an accumulator chamber that houses the biasing assembly. The motor is disposed on the first side of the manifold housing portion. The pump is disposed on a second side of the manifold portion, opposite the first side. The pump is configured to pump fluid into the accumulator chamber of the accumulator housing portion.

A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a sump and a motor. The hydraulic control unit housing has an accumulator housing portion that houses a biasing assembly and a piston. The sump is defined in the hydraulic control unit housing and at least partially occupies a common space with the accumulator housing portion. The motor is configured to pump fluid into an accumulator chamber of the accumulator housing portion. The fluid pumped into the accumulator housing portion at least partially collapses the biasing assembly and introduces a pre-charge into the hydraulic control unit. The biasing assembly is configured to expand and urge the piston in a first direction resulting in fluid being communicated from the hydraulic control unit and into the limited slip differential.

A compact planetary differential gear set includes first (A) and second (B) sun gears, a first set (A) and a second set (B) of planet gears (), and a carrier () with a ring gear (). Enmeshing gear pairs () are formed from one planet gear from each set. The first and second planet gear sets enmesh the first and second sun gears, respectively. The ring gear does not extend into an annular region containing the planet gears thereby allowing four or more gear pairs to compactly fit into the annular region. The carrier is a weldment and substantially encloses the sun gears and the planet gears permanently. The differential requires no fasteners or post-weld machining and may have a higher capacity, lower cost, smaller size, lower part number count, and/or lower amounts of material compared with conventional differentials. The differential is suited for motor vehicle applications.
