Methods and systems are provided for an actuation system for a driveline shifting member in a transmission system of a vehicle. In one example, a system may include an actuator coupled to a lever arm via one or more parallel axis gears, and a shaft connecting the lever arm to a driveline shifting member, the lever arm driven via a rolling element housed within a slot in the lever arm aligned with a center of a parallel axis gear of the one or more parallel axis gears.

Methods and systems for an actuation system

Linear actuator mechanisms () for vehicle disconnect/connect systems having a stationary guide rod (); a shift fork () the stationary guide rod extends therethough; a drive nut (); a drive screw () extending through the drive nut; a first spring plate (), a second spring plate (), and a compression spring () positioned between a radially extending portion of the first spring plate and a radially extending portion of the second spring plate. A second radially extending portion of the first spring plate and a second radially extending portion of the second spring plate are in contact with the drive nut on axially opposite sides of the drive nut. The first and second spring plates are moveable axially along the stationary guide rod by the drive nut to compress the compression spring.

Linear actuator mechanism and use in a vehicle axle disconnect/connect system

A parking lock mechanism having a motor, an actuation shaft, an engagement cam, a release cam, a cam biasing member, a pawl member and a lock gear. The engagement cam has a first side, a second side and a perforation there through. An outer edge of the engagement cam has a contact portion and an engagement portion. The release cam has a first side, a second side and a perforation there through. An outer edge of the release cam has a release member and an engagement portion. The cam biasing member has a first end, a coil portion and a second end. The pawl member has a pivot perforation, an engagement end, a locking protuberance and a sensor protuberance. The pawl member is disposed adjacent the engagement cam and the release cam. The lock gear has a plurality of inner splines and outer teeth.

Parking lock mechanism for a transmission

Described herein is a compliant plunger for a latching solenoid. The compliant plunger prevents disengagement of the solenoid when the solenoid is subjected to incidental axial movement. The compliant plunger takes advantage of a compressible compliance device to absorb the incidental axial movement.
