Abstract: A transfer case for a vehicle having a selective four wheel drive mode of operation is provided. The transfer case includes a front shell boltably connected with a rear shell, a front axle output shaft and sprocket, and a main input shaft torsionally connected with a transmission and rear axle of the vehicle. A main sprocket is provided, rotatably mounted on the main input shaft. The sprocket has an axial extension. A chain torsionally connects the main sprocket with the front axle output sprocket. A clutch housing having a splined opening is torsionally connected with the main sprocket extension. A hub is spline connected on the main input shaft. A clutch pack is selectively torsionally connected with the clutch housing and with the hub. A pressure plate is provided to actuate the clutch pack. An electrically powered ball ramp mechanism is provided for axially displacing the pressure plate to torsionally join the main input shaft to the front axle input shaft causing the main sprocket extension to contact the hub.

Abstract: 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.

Abstract: A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.

Abstract: A power transmitting component that includes a clutch, a valve and a ball ramp mechanism. The clutch has a hub, a housing, a clutch pack and an apply plate. The clutch pack has sets of friction plates that are mounted to the hub and the housing. The valve includes a valve element, which is received in a bore in the hub, an inlet and an outlet. The ball ramp mechanism has first and second ball ramp rings and is operable for selectively translating the apply plate to compress the friction plates against the housing as well as for translating the valve element to open the valve. The second ball ramp ring is coupled to the hub for rotation therewith. The first ball ramp ring is rotatable relative to the second ball ramp ring.

Abstract: A transfer case includes a primary output shaft, a secondary output shaft, a clutch, and a hub. The clutch includes a plurality of interleaved plates for selectively rotationally coupling the primary output shaft to the secondary output shaft. The hub rotationally couples the primary output shaft and the clutch. The hub includes an outer annular member and an inner annular member. The inner annular member is rotatable within the outer annular member for the hub to selectively release oil into the clutch.

Abstract: A transfer case comprises a primary output shaft, a secondary output shaft, a clutch, and a plurality of valves. The primary output shaft includes a hub rotationally coupled thereto. The clutch selectively couples the primary output shaft to the secondary output shaft to transfer torque therebetween. The clutch includes a housing, interleaved plates, and an apply plate. The housing is rotationally coupled to the secondary output shaft. The interleaved plates alternate between a first subset of the interleaved plates rotationally coupled to the hub and a second subset of the interleaved plates rotationally coupled to the housing. The apply plate compresses the interleaved plates for transferring torque between the hub and the housing. The valves selectively release oil supplied through the primary output shaft into the housing. Each valve includes a bore formed in the hub and a valve rod movable by the apply plate to open the valve.

Abstract: A friction clutch with a clutch plate having a hub member, a rim portion and a plurality of rib members. The hub member has a plurality of female hub teeth. The rim portion is disposed concentrically about the hub member and has a rim member and a friction material that is coupled to the rim member. Each of the rib members extend radially between the hub member and the rim member to couple the hub member and the rim member to one another. Each one of the rib members is intersected by at least three of the other rib members. Each of the other rib members intersecting the one of the rib members at a distinct location such that the distinct locations are spaced apart from one another along the one of the rib members.

Abstract: A power transmitting component having a first shaft and a pump. The first shaft has a longitudinal bore, a pump mount and a feed conduit. The pump mount has a circumferentially extending surface, a drive portion and a channel that extends circumferentially about the first shaft. The channel is disposed along a longitudinal axis of the first shaft between the drive portion and the circumferentially extending surface. The feed conduit intersects and fluidly couples the longitudinal bore and the channel. The pump has a pump housing, a first rotor and a pump outlet. The pump housing is mounted about the circumferentially extending surface and is disposed circumferentially about the channel. The first rotor is coupled to the drive portion for rotation therewith. The pump outlet is coupled in fluid communication with the channel.
