Abstract
An apparatus for operating a clutch in a split-axle mechanism of a vehicle for instantaneously engaging four-wheel drive. In a preferred embodiment the apparatus includes a cable operatively connected to a control switch within the passenger compartment of the vehicle and an actuator, adjacent to the split axle mechanism. Activation of the switch causes instantaneous movement of the cable which, in turn, instantaneously causes the actuator to engage or disengage the clutch. When the clutch is engaged, the split axles rotate together. When the clutch is disengaged, the split axles rotate independently. In another embodiment a locking device is used to lock the actuator in position. The actuator can be locked to engage or disengage the clutch for enabling or disabling four-wheel drive.
