Abstract:
An axle disconnect assembly for a vehicle comprising:an input shaft;a output shaft coaxially arranged proximate said input shaft;a collar engaging one of said input and said output shafts, said collar slidable to engage another of said input and said output shafts and establish a positive driving connection between said input and output shafts;a movable piston engaging said collar;a valve in communication with a oil pump of said vehicle, said valve being controlled to selectively supply pressurized oil from said oil pump to opposite sides of said piston to selectively displace said piston and thereby selectively control a position of said collar and said connection between said shafts; anda controller to selectively control said valve body between a connect mode and a disconnect mode; and said piston is disposed within and translatable within a chamber between opposite sides thereof, wherein when in said connect mode, said controller operates said valve body to establish communication of said pressurized fluid source to a first one of said opposite sides of chamber and establishes fluid communication of a second one of said opposite sides of said chamber to an exhaust port thereby moving said piston together with said collar to engage both said input and output shafts and when in a disconnect mode said controller operates said valve body to establish communication of said pressurized fluid source to said second one of said opposite sides of said chamber and establishes fluid communication of said first one of said opposite sides of said chamber to said exhaust port thereby moving said piston together with said collar to disengage one of said input and output shafts.
