Abstract
In at least some implementations, a disconnect assembly for a power transfer unit includes a cam and a cam follower. The cam is driven for rotation and has a cam surface that is inclined relative to an axis of rotation and a void spaced from the cam surface. The cam follower has a cam engagement surface and is arranged to be engaged by the cam surface so that the cam follower is displaced axially during at least a portion of the rotation of the cam. One or both of the cam and the cam follower includes an interface surface provided at an angle to the axis of rotation to control axial movement of the cam follower during at least a portion of the rotation of the cam when the cam surface is not engaged with the cam engagement surface.
