摘要： A control system for and a method of controlling a wheel hub clutch for a wheel hub. The control system includes: a stator; a translator having a permanent magnet; and wiring electrically connecting the stator to an electric power source. The stator is selectively powered through controlled electric power carried by the wiring so as to control translation of the translator through interaction between the stator and the permanent magnet of the translator, and the translation of the translator is controlled between an engaged state and a disengaged state. In the engaged state, a plurality of locking members are engaged with a plurality of notches of a selectively rotatable notch plate whereby the plurality of locking members are in a plurality of pockets of a rotatable pocket plate corresponding to the plurality of notches.

摘要： A wheel hub clutch includes: a notch plate; a pocket plate having pockets and plunger passages in communication with the pockets; locking members carried in the pocket plate pockets; and plungers carried in the pocket plate plunger passages and configured to drive the locking members into engagement with the notches in the notch plate. The clutch also may include a translator with a permanent magnet that cooperates with an electromagnet of a stator to translate the translator. The translator may be coupled to the locking members to translate them into and out of engagement with the notch plate. Also disclosed is a wheel end system including the wheel hub clutch, a drivetrain including the wheel end system and wheel hub clutch, and a vehicle including the drivetrain.

摘要： A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

摘要： A clutch device for a vehicle fan includes a drive-side clutch element and an output-side clutch element. The clutch device includes a locking mechanism configured between the drive-side clutch element and the output-side clutch element so that a rotary connection established between the drive-side clutch element and the output-side clutch element is released when a drive-side rotational speed reduces in comparison with an output-side rotational speed.

摘要： A multimode clutch assembly is positioned in a powertrain of a rotorcraft. The clutch assembly includes a freewheeling unit having a driving mode in which torque applied to the input race is transferred to the output race and an overrunning mode in which torque applied to the output race is not transferred to the input race. A bypass assembly has an engaged position that couples the input and output races of the freewheeling unit. An actuator assembly shifts the bypass assembly between engaged and disengaged positions. An engagement status sensor is configured to determine the engagement status of the bypass assembly. In the disengaged position, the overrunning mode of the freewheeling unit is enabled such that the clutch assembly is configured for unidirectional torque transfer. In the engaged position, the overrunning mode of the freewheeling unit is disabled such that the clutch assembly is configured for bidirectional torque transfer.

摘要： A bi-directional clutch assembly includes an outer race defining first and second strut pockets, an inner race defining ratchet teeth, a passive one-way clutch including at least two passive struts each supported in a corresponding first strut pocket for pivotal movement relative to the ratchet teeth, passive strut springs for normally biasing the passive struts into engagement with the ratchet teeth on the inner race, and a selectable one-way clutch having at least one active strut supported in the second strut pocket for pivotal movement between a non-deployed position disengaged from the ratchet teeth and a deployed position engaged with the ratchet teeth, and an armature ring fixed for rotation with the outer race and axially moveable between a non-actuated position and an actuated position, in which a strut engagement feature moves the active strut from its non-deployed position to its deployed position.

摘要： A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear driven by a charging motor, a freewheel coupled to the idler gear, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring arranged between the clutch blocks and is non-rotatably coupled to the first clutch block. During a rotation relative to the second clutch block, the synchronizer ring couples in a form-fitting manner to the second clutch block in a first direction of rotation about the axis of rotation.

摘要： Presented are wedge-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes an outer race that attaches to a torque converter's pump cover. The outer race's inner diameter (ID) surface has circumferentially spaced grooves. An inner race is concentrically aligned within the outer race and attaches to an engine's output shaft. The inner race's outer diameter (OD) surface has circumferentially spaced pockets. A wedge plate interposed between the inner and outer races has multiple circumferentially spaced ramps. Each ramp slidably mounts within one groove and one pocket. The wedge plate moves between an engaged position, whereat the ramps wedge between the ID and OD surfaces to thereby transfer torque between the inner and outer races, and a disengaged position, whereat the ramps unwedge to thereby free the inner race to rotate with respect to the outer race.
