Abstract
An electronic limited slip coupling constructed in accordance to one example of the present disclosure includes a sleeve, a support shaft, a hydraulic control unit, a clutch assembly and a case. The sleeve has a first set of splines projecting inwardly and meshed for engagement with an axle. The support shaft has a second set of splines configured to mesh with a first housing of a differential assembly. The hydraulic control unit has an accumulator housing and a motor. The motor is configured to pump fluid into an accumulator chamber of the accumulator housing. The clutch assembly receives fluid from the hydraulic control unit. The clutch assembly has a clutch pack positioned between a clutch piston and a portion of a clutch basket. The clutch assembly is operable to selectively interlock the sleeve and the support shaft. The case supports the electronic limited slip coupling as an assembled unit.
