  • Patent number: 11346404
    Abstract: A coupling and control assembly for use in a motor vehicle such as a hybrid vehicle is provided. The assembly includes a first coupling face of an engine powertrain component or part supported by the powertrain component for rotation therewith about an axis. The first coupling face has a first set of locking formations. The assembly also includes a coupling member supported on a stationary member of the vehicle. The coupling member has a second coupling face in close-spaced opposition with the first coupling face. The assembly further includes an electromechanical actuator to move a locking element across a gap towards the first coupling face to a coupling position in response to the actuator receiving an electrical control signal. The locking element abuttingly engages one of the locking formations to prevent rotation of the powertrain component in a first direction about the axis in the coupling position.

  • Patent number: 10982725
    Abstract: A switchable ratcheting clutch achieves four different modes of operation based on a relative rotational position of a cam ring and an inner ring. In a central relative position, an outer ring can rotate freely in either direction with respect to the inner ring. In either extreme relative position, the outer ring is prevented from rotating in either direction relative to the inner ring. In intermediate positions one either side of the central position, the outer ring is permitted to rotate in one direction but not the other. A number of pawls are supported on the inner ring and pushed radially out of engagement with the outer ring by a spring on a spring cage. The spring cage moves with the cam ring between the one-way positions but the cam ring rotates relative to the spring cage when moving into the extreme positions.

  • Patent number: 10434863
    Abstract: A multimode clutch may be adapted for selectively connecting and disconnecting front and/or rear axles from respective internal combustion engine and electric motor powertrains connected to such front and rear driving axles in a through-the-road hybrid vehicle. For example, the engine may be part of a front axle driven powertrain connected to the front wheels, while the motor may be part of a separate rear axle driven powertrain connected to the rear wheels, or vice versa. By selective disconnection of an axle not being actively driven, a real time reduction in parasitic losses may be achieved, leading to higher overall operating efficiencies. The multimode clutch offers greater flexibility over the use of standard friction clutches; each multimode clutch may provide four distinct operational modes for accommodating a wide diversity of driving conditions. For example, bi-rotational freewheeling of the rear axle may occur whenever the motor is not in use.

  • Patent number: 10100883
    Abstract: A clutch for selectively preventing rotation of a rotating component may include a first and second pawls pivotable between engagement and disengagement with the rotating component to selectively prevent or allow rotation of the rotating component in one or both directions. An armature moveable between a first and second armature positions may have a common member pivotally connected thereto and engaging the first and second pawls, with a torque spring biasing the common member to rotate toward the first pawl and away from the second pawl. In an intermediate armature position, the common member may disengage the first pawl from the rotating component while engaging the second pawl to allow rotation in one direction while preventing rotation in the opposite direction. In embodiments, a clutch may include a cam actuator rotating to selectively control engagement of the pawls with the rotating component and locking in one or both directions.

  • Patent number: 9982727
    Abstract: A selectable one way clutch includes a reverse strut pocket plate having a first plurality of struts or pawls, a reverse notch and forward strut pocket plate having a second plurality of struts or pawls, a selector plate disposed between the plates controlled by a selector plate actuator and a forward notch plate. The reverse notch and forward strut pocket plate includes a plurality of ratchet teeth disposed about its periphery which cooperate with a pin or pushrod of a linear actuator. When the reverse notch plate and forward strut pocket plate is stationary but the one way clutch is still carrying torque, the linear actuator may be actuated to rotate the reverse notch plate and forward strut pocket plate to unlock or release the torque carrying struts which would otherwise remain in their locked torque transmitting positions until all or substantially all torque across the clutch was removed.

  • Patent number: 9969064
    Abstract: A ratchet tool with stacked switching device includes a handle, two stacked engaging assemblies, two springs, a toothed wheel, and a control unit. Each of the engaging assemblies includes stacked first and second engaging members. The engaging portions of the first and second engaging members are staggered. Since the toothed wheel selectively engages with the engaging portions of the first and second engaging members, the number of teeth of the toothed wheel to be engaged with the two engaging assemblies is the sum of the number of teeth of the engaging portions of the first and second engaging members, thus enhancing the fineness of the rotation of the toothed wheel, and improving the easiness and applicability of the ratchet tool, without impacting the structural strength.

    Abstract: A transmission apparatus of a hybrid vehicle is provided. The apparatus includes a planetary gear set including a first rotation element connected to an engine, a second rotation element connected to a first motor/generator, and a third rotation element connected to a second motor/generator. An output gear is connected to any one of the second and third rotation elements and a two-way clutch is mounted at the first rotation element. The clutch limits D stage rotation in a first side direction or limits R stage rotation in a second side direction selectively based on a position of a lever. Accordingly, the clutch performs a failsafe function by preventing a shifting stage from being applied to the R stage when the engine is driven.
