A one-way roller clutch, in particular for an adjuster of a disc brake, includes an inner body having an outer lateral surface, an outer ring, which covers the outer lateral surface of the inner body by way of an inner lateral surface in such a way that a clamping gap is formed, and a roller cage. The roller cage is arranged in the clamping gap. Spring-loaded clamping rollers are held in a rollable manner and are supported on respective ramp surfaces. The roller cage is retained on the inner body for conjoint rotation.

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.

A clutch assembly includes inner and outer races supported for rotation about an axis and a one-way clutch element radially disposed between the inner and outer races. A first bearing is radially disposed between the inner and outer races and is seated on the inner race. A second bearing is radially disposed between the inner and outer races and is seated on the inner race. The first and second bearings are on opposite sides of the clutch element.

A return stop includes a rotational inner ring, a stationary, fixed outer ring, and a cage mounted radially between the inner ring and outer ring. The cage has at least two pairs of rollers each having a first and a second roller. A clamping rail is formed on an outer peripheral surface of the inner ring for each roller. A radial recess is formed on the inner ring in the peripheral direction directly adjacent to the respective clamping rail. Also, both of the clamping rails of the roller pairs are formed in the peripheral direction in opposite directions away from each other. In a free-running operation of the return stop, only one roller of each pair of rollers comes into position on the inner ring and the outer ring. The other roller of each pair of rollers does not come into position at least one the inner ring.

A cage freewheel for installation into the clamping gap of a shaft/hub connection, in particular in an e-bike drive, includes an annular cage with, following one another in the circumferential direction, bearing rollers for mounting the hub and the shaft together, and clamping bodies arranged pivotably in the cage. The clamping bodies block a relative movement between the shaft and the hub in a frictionally locking manner in one rotational direction, and allow rotation in the other rotational direction, and are spring-loaded in the coupling direction by an annular spring which extends around the row of the clamping bodies in a slot in the radially outer surface of the clamping bodies. The bearing rollers are arranged in each case in pairs in associated pockets of the cage on both sides of the annular spring. Here, the bearing rollers are received in a positively locking manner in the associated pockets.

A one-way clutch includes multiple sprags located between an outer ring member and an inner ring member, a cage that holds the sprags such that the sprags are circumferentially spaced from each other, and a spring disposed along the cage and in contact with the sprags. The cage includes a tubular body and an annular flange. The body has multiple pockets that hold the sprags. The flange extends from an axial end of the body toward the outer ring member. A clearance is formed between the outer ring member and the flange along their entire circumference.

Valve systems include a valve and a valve actuator assembly for operating the valve. The valve actuator assembly includes a drive device and a hand wheel assembly that can independently be used to cause movement of the valve. An anti-back drive component is coupled to the output of the drive device, the hand wheel assembly, or both. The anti-back drive component includes a locking device and an unlocking device, each with respective protrusions that cooperate to define cavities that house pairs of springs and rollers. The shape and orientation of the cavities allows for rotation of the rollers in the cavities and the anti-back drive component by rotating the unlocking device, while preventing rotation of the rollers and the anti-back drive component via rotation of the locking device to selectively prevent rotation of the output of the drive device, hand wheel assembly, or both.

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.

A clutch assembly includes inner and outer races supported for rotation about an axis and a one-way clutch element radially disposed between the inner and outer races. A first bearing is radially disposed between the inner and outer races and is seated on the inner race. A second bearing is radially disposed between the inner and outer races and is seated on the inner race. The first and second bearings are on opposite sides of the clutch element.

A clutch unit includes a lever-side clutch part to control transmission of rotational torque input through a lever operation, and a brake-side clutch part to transmit the rotational torque from the lever-side clutch part to an output side, and interrupt rotational torque from the output side. The brake-side clutch part includes an outer ring constrained in rotation, an output shaft configured to output the rotation, a cage arranged between the outer ring and the output shaft to receive the rotational torque from the lever-side clutch part, and a cylindrical roller to control the interruption of the rotational torque from the output shaft and the transmission of the rotational torque input from the cage through engagement and disengagement between the outer ring and the output shaft.
