<p>The invention disclosed herein relates to an armored vehicle having a rotatable cupola or turret for rotating a weapons system to the target. A system for driving the turret through an arc of rotation includes a ring gear fixed to the vehicle body and a pinion gear fixed for relative rotation to the turret for engaging the ring gear. The pinion gear is driven by a hydraulic motor to rotate the pinion and ultimately drive the turret. Integrated with the hydraulic motor and the ring gear is a manual disconnect apparatus which provides for manual operation in lieu of the motorized operation of the pinion gear. This manual apparatus includes a series of gears and an actuating assembly for moving at least one of the gears between an operative mode when a manual drive train is connected with the pinion gear and an inoperative mode when the manual drive train is disconnected from the pinion gear.</p> |
