Shift collar assembly for a power transfer unit
First Claim
1. A disconnect assembly for a power transfer unit, comprising:
- an input shaft rotated about an axis and having an end portion with a flange;
a disconnect shaft axially aligned with the input shaft;
a collar movable relative to the input shaft and disconnect shaft from an engaged position wherein the collar couples together the input shaft and the disconnect shaft so that rotation of the input shaft causes rotation of the disconnect shaft and a disengaged position wherein the collar does not couple the input shaft and disconnect shaft and the disconnect shaft does not rotate with the input shaft; and
a shock absorbing device carried by the input shaft to engage the collar when the collar is in its engaged position, wherein the flange supports the shock absorbing device and permits the shock absorbing device to be compressed between the collar and the flange.

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.

17. A disconnect assembly for a power transfer unit, comprising:
-
an input shaft rotated about an axis and having a channel formed in the input shaft; a disconnect shaft axially aligned with the input shaft; a collar movable relative to the input shaft and disconnect shaft from an engaged position wherein the collar couples together the input shaft and the disconnect shaft so that rotation of the input shaft causes rotation of the disconnect shaft and a disengaged position wherein the collar does not couple the input shaft and disconnect shaft and the disconnect shaft does not rotate with the input shaft; and a shock absorbing device received within the channel and arranged so that when the collar is in its engaged position the shock absorbing device is compressed between the collar and a portion of the input shaft. - View Dependent Claims (18)

19. A disconnect assembly for a power transfer unit, comprising:
-
an input shaft rotated about an axis; a disconnect shaft axially aligned with the input shaft; a collar movable relative to the input shaft and disconnect shaft from an engaged position wherein the collar couples together the input shaft and the disconnect shaft so that rotation of the input shaft causes rotation of the disconnect shaft and a disengaged position wherein the collar does not couple the input shaft and disconnect shaft and the disconnect shaft does not rotate with the input shaft; and an annular shock absorbing device received around the input shaft and having an inner diameter smaller than an outer diameter of a portion of the input shaft so that the shock absorbing device is carried by the input shaft and the shock absorbing device is arranged so that when the collar is in its engaged position the shock absorbing device is compressed between the collar and a portion of the input shaft. - View Dependent Claims (20, 21)
