Electric clutch for work vehicle power shift transmission

A transmission for a work vehicle, the transmission comprising:

• an output shaft;
• a gear providing a gear ratio;
• an electric clutch coupling the gear to the output shaft when engaged, the electric clutch comprising:
• a clutch pack having clutch members transmitting torque when engaged;
• an input mechanism including:
• a pinion gear configured to receive rotational input from an electric machine;
• and
• a cam gear meshing with the pinion gear to rotate about a reference axis, the cam gear having a cam follower;
• and
• an actuator assembly including:
• an actuator spring;
• a cam disc disposed about the reference axis and engaging the cam gear at a cam ramp such that changing a clock position of the cam gear about the reference axis imparts translation of the cam disc along the reference axis to move the actuator spring, wherein the cam disc defines the cam ramp which is engaged by the cam follower to effect translation of the cam disc along the reference axis;
• and
• an actuator piston moved by the actuator spring in response to the translation of the cam disc to engage the clutch members of the clutch pack.
