At least one of the coil housing and the armature has a contact pressure reducing portion for reducing contact pressures of the frictional engagement faces of the coil housing and the armature, generated based on cam thrust generated through an operation of the cam mechanism when the frictional engagement faces of the coil housing and the armature are frictionally-engaged. | 04-18-2013 |
20130277165 | Electromagnetically Actuated Clutch - A clutch mechanism includes a coil of wire for producing an electromagnetic field, a locking ring secured against rotation within a case or housing, a gear engageable with the locking ring, and a lever that pivots in response to the electromagnetic field produced by energizing the coil causing the locking ring to engage the gear and hold the gear against rotation. | 10-24-2013 |
20150144453 | TORQUE TRANSFER MECHANISM WITH SEALED BALL-RAMP CLUTCH OPERATOR UNIT - A torque transfer mechanism is provided for controlling the magnitude of a clutch engagement force exerted on a multi-plate clutch assembly that is operably disposed between a first rotary and a second rotary member. The torque transfer mechanism includes a power-operated clutch actuator for generating and applying a clutch engagement force on the clutch assembly. Clutch actuator assembly includes a clutch apply operator for controlling the magnitude of a clutch engagement force applied to the clutch assembly. The clutch operator includes a first and second cam plate that are spaced form in one another to define a cavity therebetween. A sealing element extends between the first and second cam plates to seal the cavity between the first and second cam plates for retaining fluids in the cavity. | 05-28-2015 |
20150308519 | ELECTROMAGNETIC PULSE DISCONNECT SYSTEM AND METHODS - 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. | 10-29-2015 |
