摘要： A rotation transmission device is configured such that when an electromagnet of an electromagnetic clutch is energized, an armature is attracted toward a rotor, so that a control retainer defining a two-way clutch is moved in an axial direction, whereby the control retainer and a rotary retainer are rotated relative to each other in a direction in which circumferential widths of pockets decrease, thereby disengaging pairs of rollers from an inner periphery of an outer ring and an outer periphery of an inner ring. The rotation transmission device includes a shock absorbing member on a surface of the armature facing the rotor, the shock absorbing member being configured to absorb impact force when the armature is attracted to the rotor by being elastically deformed.

摘要： A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

The connection unit may include a solenoid coil, an armature co-axial with the first and the second shafts, a plurality of balls positioned around the armature. The armature may include a first cylindrical segment and a second cylindrical segment. The armature may be selectively movable between a first axial position and a second axial position. When the armature is in a first axial position, the balls are positioned to transmit torque forces between the first shaft and the second shaft. When the armature is in a second axial position, the first shaft and the second shaft are free to rotate independently.

摘要： An electromagnetic clutch includes a base portion, a driving member, a driven unit including an output shaft, and an electromagnetic solenoid. The driving member, the driven unit, and the electromagnetic solenoid are assembled on the base portion. The driven unit includes an intermediate member that engages with the output shaft to transmit a torque while being relatively moved towards a rotational axis, the intermediate member being magnetically attracted to the base portion. The driven unit also includes a rotation member that is biased towards the driving member and that is pivotally supported to transmit a rotation of the driving member to the output shaft, a guide mechanism that causes the rotation member to be separated from the driving member while the intermediate member is restrained from moving by being magnetically attracted, and a holding mechanism holding a position of the rotation member that is separated from the driving member.

摘要： A rotation transmission device has a housing having an end wall with a shaft hole. An input shaft is inserted through the shaft hole, and an inner ring is mounted around the end of the input shaft inside the housing. A two-way clutch is provided between the inner ring and an outer ring disposed around the inner ring, and an electromagnetic clutch is provided adjacently, controlling engagement and disengagement of the two-way clutch. A first bearing mounted between radially facing surfaces of the housing and the outer ring is an open bearing, provided with a labyrinth on its end near the side of the open end of the housing. A second, single-sealed bearing is provided between facing surfaces of the inner ring and the outer ring, supporting these rings rotatably relative to each other. Lubricating grease with the same quality is used for the second bearing and the two-way clutch.

摘要： An electromagnetically operated unit for controlling a radial connection. The unit has a first device which is optionally coupleable with a second device. The second device includes a magnet and/or electromagnet. The unit also has radially movable switching elements that are supported about the circumference of one of the devices, which additionally has contoured and/or frictional surfaces, which mate with respective contoured and/or frictional surfaces of the other one of the devices, thus effectuate engagement of the first and second devices. When the unit is designed with a closed current system the switching elements are biased to disengage when current is applied to the magnet and with an open current system the switching elements are biased to engage, against the force of a spring, when current is applied to the magnet.
