動力伝達ユニットのための、負荷がかけられたシャフトを結合解除するためのデバイス

摘要

A device for uncoupling a drive shaft of a piece of equipment from an input shaft. The device includes a claw including first teeth and first splines to (i) move longitudinally along a first of the shafts by co-operating with second splines borne by the second of the shafts and (ii) engage or disengage the first teeth in relation to the second teeth positioned on the second shaft. The device also includes a longitudinal movement mechanism including a stationary part acting on a longitudinally mobile piece to move the claw between a coupling position and an uncoupling position. The longitudinal movement mechanism drives the claw by co-operation between a rotationally fixed piece and a piece that is linked to the claw and rotated therewith, a longitudinal clearance being maintained during operation between the piece that is rotationally fixed and the rotated piece.
