Classification: CPC F  B | IPC F

Claim 7:
8. A shift actuator comprising:
a drum cam having a disconnect track and a range track, wherein the drum cam rotates about a rotational axis, wherein the drum cam is positioned around a drum shaft, wherein the drum cam and the drum shaft are rotationally fixed with respect to one another, and wherein the drum cam is axially slidable relative to the drum shaft;
a fork assembly that is positioned parallel with the rotational axis;
a fork rod that is positioned parallel with the rotational axis, wherein the fork assembly slidably couples the disconnect track with the fork rod and slidably couples the range track with the fork rod, wherein
the disconnect track and the range track define a plurality of actuating positions of the fork assembly that are oriented generally perpendicular to the rotational axis;
rotation of the drum cam with the fork assembly in one actuating position of the plurality of actuating positions defines a flat portion characterized by at least a portion of the fork assembly being maintained in a single axial position with respect to the drum cam; and
the rotation of the drum cam in the flat portion builds momentum for operating the fork assembly through sloped portions of the disconnect track and the range track, the sloped portions being oblique to the rotational axis.
