Compact electromagnetic pulse disconnect system
Methods and systems are provided for an electromagnetic pulse disconnect assembly. In one example, an electromagnetic disconnect assembly includes an electromagnetic coil assembly including an electromagnetic coil, an armature cam including an annular ring and a plurality of bidirectional cam ramps extending in an axial direction from the annular ring, where the annular ring is adapted to have face-sharing contact with the electromagnetic coil assembly when the electromagnetic coil is energized and be spaced apart from the electromagnetic coil assembly when the electromagnetic coil is de-energized, and a cam follower a plurality of radially extending guides arranged around a circumference of the cam follower and spaced apart from one another via a plurality of elongate apertures, each of the plurality of elongate apertures adapted to receive one of the plurality of bidirectional ramps of the armature cam. The assembly may further include a latching system.
COUPLING AND CONTROL ASSEMBLY INCLUDING A NON-CONTACT, LINEAR INDUCTIVE POSITION SENSOR
A coupling and control assembly including a non-contact, linear inductive position sensor is provided. The assembly includes a coupling housing and a stator structure disposed within the coupling housing and including a stator housing. A translator structure is coupled to a coupling member of the assembly to rotate therewith about a rotational axis. The sensor is mounted on one of the housings. The translator structure includes a coupler element made of an electrically conductive material. The sensor is configured to create a magnetic field to induce eddy currents in the electrically conductive material. Movement of the coupler element changes a magnetic field caused by the eddy currents. The sensor provides a position feedback signal for vehicle transmission control. The signal is correlated with the linear position of the translator structure along the rotational axis.
Dynamic controllable dog clutch
A dynamic controllable dog clutch (DCDC) includes a pocket plate, a notch plate, and a linear actuator having a stator and a translator. The translator is axially movable between (i) an engaged position in which a locking member axially extends through the a pocket of the pocket plate and engages a notch of the notch plate to thereby mechanically couple the pocket plate and the notch plate together to prevent relative rotation of the pocket plate and the notch plate with respect to each other about a common rotational axis and (ii) a disengaged position in which the locking member is disengaged from the notch of the notch plate to thereby mechanically decouple the pocket plate and the notch plate together to enable relative rotation of the pocket plate and the notch plate with respect to each other about the common rotational axis.
LOCKING STRUCTURE OF DIFFERENTIAL
The present disclosure discloses a locking structure of a differential. The locking structure comprises a bi-stable electromagnetic clutch sleeved on an output axle shaft on one side of the differential. The bi-stable electromagnetic clutch comprises a movable locking disc and a fixed locking disc; the fixed locking disc is fixedly connected to a differential housing or integrated with differential housing, and the movable locking disc and the fixed locking disc have face teeth that can engage with each other. The movable locking disc is sleeved on the output axle shaft, the bi-stable electromagnetic clutch drives the movable locking disc to move axially after being energized, the output axle shaft and the differential housing are locked when the movable face teeth engaged with the fixed face teeth so that the output axle shaft on either side of the differential and the differential housing have a same rotational speed and output torque. The locking structure has the advantages of bi-stable or bi-state, controllability, and a long service life.
