Abstract

A gear box has a clutch comprising a hub and a coupling, each having drive portions that are movable between engaged and disengaged positions. In the engaged position, the hub and coupling drive portions are engaged in a manner to allow torque to be transmitted between the hub and the coupling. In the disengaged position, the hub and coupling drive portions are spaced apart in a manner to prevent torque from being transmitted between the hub and the coupling. The clutch has an actuator that moves the hub and coupling drive portions between the engaged and disengaged positions. In moving the hub and coupling drive portions to the engaged position, the actuator is driven by spring pressure. In moving the hub and coupling drive portions to the disengaged position, the actuator is driven by hydraulic pressure supplied against the actuator sufficient to overcome the spring pressure.
