Abstract
A disconnect mechanism to disconnect an electric machine from an ancillary component includes a ramp shaft connected to a disconnect shaft of the electric machine, and connected to the ancillary component, such that when connected to the ancillary component the disconnect shaft transmits rotational energy between the electric motor and the ancillary component. The ramp shaft includes a disconnect feature. A plunger is selectably engageable with the disconnect feature to disconnect the ramp shaft from the disconnect shaft. The disconnect feature includes a drop-in window for initial engagement with the plunger, and a ramp surface extending in a circumferential direction from the drop in window at an acute angle relative to the drop in window. Engagement of the plunger with the ramp surface urges movement of the ramp shaft in an axial direction away from the disconnect shaft to disconnect the ramp shaft from the disconnect shaft.
