Driveline disconnect device

摘要

In at least some implementations, a disconnect assembly for a driveline component, such as a power transfer unit, may include an input shaft, a disconnect shaft selectively rotated by the input shaft and an output shaft coupled to the disconnect shaft. A first gear is coupled to the disconnect shaft and a second gear is coupled to the output shaft and to the first gear so that the output shaft rotates when the disconnect shaft rotates. A connection feature is movable between an engaged position in which the input shaft and disconnect shaft are coupled and a disengaged position in which the input shaft rotates relative to the disconnect shaft. The connection feature includes a first part carried by the gear for rotation therewith and a second part movable relative to the first part and carried by the input shaft for rotation with the input shaft.

1. A disconnect assembly for a driveline component, comprising:
an input shaft rotated about an axis; a disconnect shaft selectively rotated by the input shaft; a first gear coupled to the disconnect shaft for rotation with the disconnect shaft; an output shaft; a second gear coupled to the output shaft and to the first gear so that the output shaft rotates when the disconnect shaft rotates; and a connection feature that is movable between an engaged position in which the input shaft and disconnect shaft are coupled for co-rotation and a disengaged position in which the input shaft rotates relative to the disconnect shaft, the connection feature including a first part carried by the first gear for rotation with the first gear and a second part movable relative to the first part and carried by the input shaft for rotation with the input shaft, wherein the connection feature is driven to the disengaged position and releasably held in the disengaged position and the connection feature is biased to the engaged position so that the connection feature remains in the engaged position absent a stronger force applied to the connection feature.
