A number of variations may include a product including a single clutch pack having a plurality of clutch plates, and a first friction material on a first plate of the plurality of clutch plates, and a second friction material on a second plate of the plurality of plates, the first friction material being different than the second friction material, and constructed and arranged to provide a tailored combination of torque capacity and response time that would be produced by a clutch pack having solely the first friction material on plates thereof or the second friction material on plates thereof.

A lubrication and hydraulic actuation system for a transfer case () includes a pump (), a pump sump () formed in the transfer case (), and having an opening () in communication with an interior of the transfer case (), and a fluid retention element (). The fluid retention element () is disposed in the opening () of the pump sump () and has at least one baffle structure () to allow fluids to enter the pump sump () through the fluid retention element () and restrain fluids from exiting the pump sump () through the fluid retention element ().

A transfer case for a normally rear wheel drive vehicle having selectively engageable front wheel drive is provided. The transfer case includes a rear housing with a main drive shaft aperture and an aluminum cast front housing threadably connected with the rear housing. The front housing has a main drive shaft aperture axially aligned with the rear housing main drive shaft aperture. The front housing has an integrally formed cylindrical yoke forming an isolation mount for receiving a polymeric isolator allowing for connection of the transfer case with a chassis structure of the vehicle. The cylindrical yoke has a cylindrical preform therein.

A transfer case and hydraulic clutch assembly for a motor vehicle driveline include a hydraulic fluid circuit in communication with a cavity disposed opposite a piston from a clutch pack for delivering pressurized fluid to the cavity for biasing the piston towards the clutch pack thereby activating the clutch. The transfer case and hydraulic clutch assembly also include a lubricant fluid circuit that is in communication with the chain that links the input sprocket to the output sprocket during use, as the chain rotates around the input sprocket and output sprocket, the lubricant fluid drips from or is sprayed from the chain. At least part of this released fluid is captured by a screen disposed above the hydraulic fluid reservoir. The screen removes any metal particles or debris and then passes the screen fluid into the hydraulic fluid reservoir thereby replenishing the hydraulic fluid reservoir without resorting to a time consuming and costly maintenance procedure.

Shift control assembly for a power transmission device includes an electric drive motor and gear train having an output which is coupled to and bi-directionally rotates a shift rail. The shift rail includes a pair of spaced-apart cam followers. Freely rotatably receiving the shift rail and disposed thereon between the cam followers is a shift fork assembly. The shift fork assembly includes a body having a pair of spaced-apart helical cam surfaces engaged by the cam followers and a fork engaging a shift clutch collar. As the shift rail rotates bi-directionally, the shift fork assembly and clutch collar bi-directionally translate. A circular plate is disposed for rotation with the shift rail and includes an array of apertures. A plurality of sensors are disposed in adjacent, sensing relationship to the circular plate. As the circular plate and shift rail rotate, the sensors generate unique combinations of signals corresponding to a plurality of specific angular positions of the shift rail and translational positions of the shift fork.
