<p>The present invention relates to a device (10) for uncoupling a vehicle's wheel shaft drive, which device is intended to be placed close to a drive shaft (11) in order to uncouple/couple a driven unit to which the drive shaft (11) is coupled. The device (10) comprises: - at least one bearing (12) fitted round the end (13) of the drive shaft (11); - a carrier (14) which is coupled to the unit or to the drive shaft, has an inner cavity large enough to surround the drive shaft's end (13) and the bearing (12) and is fastened in the bearing (12) so as to be freely rotatable relative to the drive shaft (11); - a coupling ring (15) coupled rotationally to the drive shaft (11) and movable axially relative to the drive shaft (11); - a coupling fork (17) which at least partly surrounds the coupling ring (15) and is movable axially relative to the drive shaft (11); and - an activating device (20) which acts upon the coupling fork (17) to move the latter in axial directions along the drive shaft (11); whereby coupling the drive shaft (11) to the unit involves the coupling fork (17) and the coupling ring (15) being moved axially towards the carrier (14) by the activating device (20) so that the drive shaft (11) becomes rotationally coupled with the carrier (14) and the unit via the coupling ring (15).</p> |
