Abstract
A wheel disconnect system is provided including a rear drive module and a constant velocity joint housing. The rear drive module includes a housing, at least one actuator, and at least one dog clutch. The dog clutch includes a first portion configured to move when the actuator is moved and a second portion configured for engagement with the first portion. The constant velocity joint housing is formed integrally with the second portion of the dog clutch. A wheel may be disconnected from the rear drive module unless engagement of the first and second portions of the dog clutch allows torque to be transferred to the wheel. In one embodiment, a hydraulically activated piston may be used to activate the first portion of the dog clutch. In another embodiment, a ball ramp may be used to activate the first portion of the dog clutch. A vehicle driveline including a wheel disconnect system is also provided.
