Abstract
A ball cam actuated dog clutch assembly for a motor vehicle transmission includes a clutch sleeve having a plurality of gear teeth positioned at a first end and multiple ball bearings disposed at a second end. A clutch hub having multiple helical grooves is created in an outer facing wall. Each of the helical grooves receives a portion of one of the ball bearings. An actuator member acts to rotate the clutch hub. Rotation of the clutch hub causes axial translation of the clutch sleeve in a selected one of a first direction or an opposite second direction by translation of the ball bearings within the helical grooves.
