摘要： A clutch assembly is disclosed herein that generally has at least three operating conditions: an open condition, a transition condition, and a locked condition. The operating conditions are achieved based on displacement of a dog clutch ring relative to a pocket ring and a cam ring. In the open condition, rockers of a ratcheting assembly are completely disengaged from ramps on a cam ring. In the transition condition, the rockers engage with the ramps on the cam ring to allow a ratcheting motion in one rotational direction and a locked state in the other rotational direction. In the locked condition, splines on the dog clutch ring engage with splines on the cam ring to provide a rotationally fixed connection in both rotational directions.

摘要： A switchable one-way clutch is provided for selectively switching between operating as a one-way clutch and a bi-directional locking clutch. The clutch includes a housing, and an outer race and an inner race, which is fixed rotationally to the housing. The clutch also includes a roller cage assembly having a plurality of rollers contactable with the inner race and the outer race. A roller cage is configured to position and contain the plurality of rollers therein. The clutch also includes an annular drag plate contacting the inner race. The drag plate is rotationally fixed to the roller cage and is moveable in an axial direction relative to the roller cage. An electromagnet assembly is configured to magnetize in response to electric energy. Via selective magnetization to attract the drag plate axially, the clutch can switch between operating modes.

摘要： A dog clutch with ratcheting one-way clutch includes an axis, a dog clutch ring, a first ring, a second ring, and a plurality of rockers. The dog clutch ring has a plurality of first teeth. The first ring includes a plurality of second teeth, complementary to the first teeth, a first spline for receiving a first shaft, and a plurality of first pockets. The second ring includes a plurality of third teeth, complementary to the first teeth, a second spline for receiving a second shaft, and a plurality of second pockets. The plurality of rockers is disposed in a one of the plurality of first pockets or the plurality of second pockets for selectively engaging with the other one of the plurality of first pockets or the plurality of second pockets to prevent rotation of the first ring relative to the second ring in only one rotational direction.

摘要： An assembly for a one-way clutch (OWC) includes a carrier, an outer race non-rotatably fixed to the carrier, an inner race, and a roller cage assembly. The roller cage assembly is disposed radially between the inner race and outer race to enable relative rotation therebetween. The roller cage assembly has a plurality of rolling elements and an annular cage and is configured to maintain the rolling elements in position. The cage including a flange extending radially inwardly. A support shim has an axial surface that contacts the flange, wherein the support shim is configured to absorb axial forces transmitted through the flange.

摘要： A switchable one-way clutch includes an outer race, an inner race, a plurality of rollers, and a drag plate. The outer race has a ramped inner surface. The rollers are contactable with the outer race and the inner race. The cage is for positioning the plurality of rollers. The drag plate is rotationally engaged with the cage and frictionally engageable with the inner race. In an example embodiment, the cage has a notch and the drag plate has a tab installed in the notch to engage the drag plate to the cage. In an example embodiment, the drag plate or the inner race includes a friction material ring bonded thereto for increasing a friction coefficient between the drag plate and the inner race. In an example embodiment, the clutch has an arc spring. The outer race includes a pocket, the cage includes a tab, and the arc spring contacts the pocket and the tab to displace the cage in a first rotational direction. In an example embodiment, the inner race includes an inner splined surface.

摘要： An electric drive for a vehicle implements a disconnect feature to reduce parasitic losses when the electric drive is not necessary for propulsion. The disconnect feature utilizes a slipper clutch which is disengaged by holding a slipper ring in a predefined circumferential position relative to an outer ring using a set of pins that move radially. A lever spring biases the pins to the outward radial position. A solenoid moves a plunger axially which pushes the pins radially inward.

摘要： A clutch assembly comprises an actuation assembly, an outer ring, and an inner ring disposed radially inward of the outer ring and rotatable about an axis in first and second rotational directions. A first and second strut are rotatably disposed within first and second pockets of the outer ring and configured to be rotated by the actuation assembly. A first pawl and a second pawl are rotatably disposed within a third pocket and a fourth pocket, respectively. For a transition mode, the actuation assembly is configured to rotate the first strut within the first pocket such that rotation of the first strut in the first rotational direction urges the first pawl radially inward into partial engagement with teeth disposed on an outer surface of the inner ring, the second pawl remains free of contact with the inner ring and the inner ring rotates in the first rotational direction.
