Abstract
A selectable one-way clutch includes a clutch module and at least one electromagnetic actuator module. Each electromagnetic actuator module includes at least one electromagnetic actuator assembly having a coil assembly, a locking strut, and a connection member mechanically interconnected to the locking strut for moving it between released and deployed positions in response to energization of the coil assembly.
Claims20
A selectable one-way clutch, comprising:
- a clutch module including a first clutch member and a second clutch member having a plurality of cam surfaces, wherein at least one of said first and second clutch members is adapted to rotate relative to the other of said first and second clutch members;
- and
- an electromagnetic actuator including an energizeable coil assembly secured to said first clutch member, a first member mounted on said first clutch member for pivotal movement relative to said coil assembly between a non-actuated position and an actuated position, a second member mechanically coupled to said first member such that movement of said first member between its non-actuated and actuated position causes concomitant pivotal movement of said second member between a released position displaced from engagement with said cam surfaces on said second clutch member and a locked position in engagement with one of said cam surfaces on said second clutch member, and a biasing member for normally biasing said second member to its released position.
A selectable one-way clutch comprising:
- a first clutch member;
- a second clutch member rotatable relative to said first clutch member and having a plurality of ratchet teeth;
- an electromagnetic actuator having an energizeable coil assembly secured to said first clutch member;
- a magnetic armature having a first end segment retained in an armature pivot channel formed in said first clutch member to facilitate pivotal movement of said armature relative to said coil assembly between a non-actuated position when said coil assembly is non-energized and an actuated position when said coil assembly is energized, and a second end segment;
- a non-magnetic strut having a base segment disposed in a strut pivot channel formed in said first clutch member and engaging said second end segment of said armature, and an engagement end segment, wherein movement of said armature between its non-actuated and actuated positions cause concomitant pivotal movement of said strut from a released position whereat said engagement end segment is disengaged from said ratchet teeth on said second clutch member and a locked position whereat said engagement end segment is in latched engagement with said ratchet teeth;
- and
- a biasing member normally biasing said strut to its released position.
