Abstract

A wedge clutch includes a hub supported for rotation about an axis and having an outer surface about a peripheral of the hub. The outer surface has a plurality of ramped surfaces. A carrier is also supported for rotation about the axis and has an inner surface. An inner surface of the disk is configured to slide along the ramped surfaces of the hub. The disk is moveable between an expanded position in which an outer surface of the disk engages the inner surface of the carrier to lock the clutch and a contracted position in which the clutch is unlocked. An armature is disposed in the disk and is configured to react to an electromagnetic force to alter the disk between the expanded position to the contracted position.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 15 / 456,705, filed March 13, 2017, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to a sprag clutch for selectively coupling two or more powertrain components to each other. Background technique [0004] In a motor vehicle, a four-wheel drive system or an all-wheel drive system may be selectively activated by a clutch. The clutch may be part of a power transfer unit (PTU) used to connect the power source to the secondary drive shaft when power needs to be transferred to the secondary drive shaft. Such clutches are known as dog clutches. Dog clutches are prone to tooth strike or jamming. It is also known that such a clutch can be a wet clutch in a differential. A continuous supply of pressurized fluid is necessary to maintain the clutch in the closed mode, thereby increasing the power us...
