A slide flange is used with a rotary body having a clutch rotatable about an axis and a pair of proximity sensors apart from each other in a circumferential direction. The slide flange is comprised of: an inner ring portion fitting on the rotary body and movable in a direction along the axis from a first position where the clutch gets connected to a second position where the clutch gets disconnected; an outer ring portion unitarily elongated from the inner ring portion and so disposed as to at least at the second position face the pair of proximity sensors; a plurality of notches formed on the outer ring portion at even intervals in the circumferential direction; and a coupling portion elongated from the outer ring portion toward the rotary body, the coupling portion being so coupled with the clutch as to rotate the outer ring portion along with the clutch.

A drive module having a housing, an input pinion, a ring gear driven by the input pinion, a ring gear bearing supporting the ring gear for rotation relative to the housing, a pair of output shafts and a clutch that selectively transmits rotary power between the ring gear and the output shafts. The clutch includes a clutch input, which is rotatably coupled to the ring gear, a clutch plate separator that is rotatably coupled to the clutch input, a pair of clutch outputs, which are each coupled to a respective one of the output shafts, a pair of clutch packs, which transmit rotary power between the clutch input and a respective one of the clutch outputs, and a pair of apply pistons. The apply pistons are housed in the clutch plate separator.

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.
