摘要： A controllable one-way clutch having a clutch module and a power-operated actuator module. The clutch module includes a first clutch component rotatably driven by an input member, a second clutch component rotatably driving an output member, struts disposed on the first clutch component for movement between a deployed position engaging ratchet teeth on the second clutch component and a non-deployed position disengaged from the ratchet teeth, and strut springs for biasing the struts toward their deployed position. The power-operated actuator module includes a coil unit, an armature moveable between an engaged position whereat the armature holds the struts in their non-deployed positions when the coil unit is powered-off and a released position where the armature releases the struts when the coil unit is powered-on, and a ballramp mechanism configured to move the armature along a helical path between its engaged and released positions.

摘要： An electromagnetic dog clutch is disclosed to solve the technical problem in conventional electromagnetic dog clutches that the friction is easy to occur between a bearing seat and an end cap of a movable gear sleeve. The electromagnetic dog clutch comprises a movable gear sleeve (5) and a fixed gear sleeve (12) that mesh with each other for transmission. A first end cap (6) is provided on an outer side of the movable gear sleeve (5), a bearing (1) is provided on an outer circumference of the movable gear sleeve (5), the bearing (1) is embedded in a bearing seat (7), a rear end of the bearing seat (7) is provided with a positioning surface, and a front end of the first end cap (6) is a vertical plane that matches the positioning surface of the bearing seat (7). The front end of the first end cap (6) is provided with a positioning pin (15), the rear end of the bearing seat (7) is provided with a positioning hole to cooperate with the positioning pin (15), and the positioning pin (15) is inserted into the positioning hole to limit the bearing seat (7) and the first end cap (6) so that they can move in an axial direction relative to each other but cannot rotate relative to each other, thereby preventing the occurrence of friction between them.

摘要： The present disclosure relates to the technical field of clutches, and particularly relates to an electromagnetic jaw clutch. The electromagnetic jaw clutch includes a movable gear sleeve and a fixed gear sleeve that are in engagement transmission, a fixed armature is nested to an outer side of the fixed gear sleeve, the fixed armature and the fixed gear sleeve have a gap therebetween, and have a fixed position, a solenoid is provided inside the fixed armature, a movable armature is rotatably nested to an outer side of the movable gear sleeve, the movable armature is movable along with the movable gear sleeve in an axial direction, and when the solenoid is electrified, the solenoid attracts the movable armature to the fixed armature, to cause the movable gear sleeve and the fixed gear sleeve to be engaged. The present disclosure provides an electromagnetic clutching system that has a compact structure, has no auxiliary executing structure and can be conveniently operated, which can be applied to electrically driving systems of new-energy vehicles. The system controls the transmission and disconnection of power torque.

摘要： A clutch assembly for the drive train of a motor vehicle includes a ratchet pawl carrier, which can be coupled to a first coupling element in a rotationally fixed manner, and a ratchet pawl counter element, which can be coupled to a second coupling element in a rotationally fixed manner. In a coupled state, ratchet pawls fastened to the ratchet pawl carrier engage in respective associated coupling recesses provided on the ratchet pawl counter-element. In a decoupled state, the ratchet pawls are positioned outside the coupling recesses. Each of the locking pawls is thereby loaded into a first locking pawl position by means of a respective associated spring, and can be loaded into a second locking pawl position by means of an associated actuating tappet.

摘要： In at least some implementations, a system for a vehicle differential having multiple gears includes a coil of wire, a drive member movable in response to a magnetic field generated by application of electricity to the coil between a first position and a second position, and a lock member coupled to the drive member for movement with the drive member throughout a range of movement of the drive member. The lock member is adapted to engage a gear of the differential when the drive member is in the second position and the lock member is adapted to be disengaged from the gear when the drive member is in the first position. In this way, the differential may be selectively locked.

摘要： Methods and systems are provided for operating an electromagnetic pulse disconnect assembly for selectively engaging two rotating components of a vehicle drivetrain. A disconnect assembly is needed that is not powered by vacuum diverted from an engine of the vehicle, as modern engines are being developed to reduce vacuum production and remove vacuum lines for powering peripheral devices such as disconnects. An electromagnetic pulse disconnect assembly is provided that operates via pulses of electrical current and includes an electromagnetic coil for translating a clutch ring assembly and a latching ring assembly to selectively couple two rotating components.

摘要： An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. In a first embodiment, the pawl clutch holds a member against rotation in one direction when engaged and permits rotation in the other direction. In a second embodiment, the pawl clutch prevents relative rotation between two rotatable members in one direction when engaged and permits relative rotation in the other direction. In either embodiment, the coil is stationary.
