Abstract: The present disclosure relates to a limited-slip driveline apparatus including a first driveline component that is rotatable relative to a second driveline component. The driveline apparatus also includes a clutch configured to resist relative rotation between the first driveline component and the second driveline component at least when the clutch is actuated. The driveline apparatus further includes an actuation arrangement for actuating the clutch. The actuation arrangement includes a hydraulic pump that pumps hydraulic fluid through a hydraulic circuit when relative rotation exists between the first and second driveline components. The hydraulic pressure generated by the hydraulic pump within the hydraulic circuit is used to actuate the clutch. The actuation arrangement also includes a flow regulating valve for regulating a hydraulic fluid flow rate through the hydraulic circuit. The flow regulating valve is configured to prevent the hydraulic fluid flow rate from exceeding a set maximum flow rate regardless of a magnitude of the hydraulic pressure in the hydraulic circuit.

Abstract: 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.

Abstract: A limited slip differential assembly includes a planetary gear assembly, a differential case, a differential gear assembly and a hydraulic clutch assembly. The differential case is coupled for rotation with a portion of the planetary gear assembly. The differential gear assembly is arranged within the differential case and includes a first side gear and a second side gear for coupling with first and second drive wheels of a vehicle, respectively. The hydraulic clutch assembly includes a clutch pack and a clutch actuator. Pressurized hydraulic fluid from a transmission pump is selectively provided to the clutch pack to actuate the clutch pack between an open configuration, in which the side gears rotate independently, and a fully closed configuration, in which the side gears rotate together such that the first and second drive wheels rotate at a same speed.
