ABSTRACT:
An improved limited slip differential unit includes a torque transmitting coupling which provides for two separate stages of driving action from a drive train to two axle shafts connected to the differential unit. A first stage of operation provides for normal differential action of the unit with no tendency to limit such action or to lock the two axle shafts to each other in their driving relationship with the drive train. A second stage of operation provides for a limitation of differential action under extreme or abnormal driving conditions, and this stage of operation can include a complete locking of the two axle shafts to each other in their relationship to the drive train.
