Emergency drive system for the aiming optics of an armoured vehicle

摘要

The invention proposes an emergency drive system for the aiming optics of an armoured vehicle, by means of which system highly accurate elevation-dependent slaving of the aiming optics is made possible in the event of failure of an otherwise normal electrical drive system. In comparison with conventional emergency drive systems, using which the desired high accuracy for elevation-dependent slaving of the target optics cannot be achieved despite considerable adjustment complexity, the emergency drive system according to the invention offers the advantage that it manages without any complex adjustment and, furthermore, can be accommodated in tank turrets in a more space-saving manner than previously known emergency drive systems. The emergency drive system (10) according to the invention is designed as a type of belt drive and essentially comprises a drive shaft (24), which is hinged on a trunnion (22) of a panel (20), and a slave shaft (18), which is hinged on the aiming optics (16), both shafts (24, 18) being connected by means of at least one steel belt (28) in order to transmit the elevation-dependent rotary movement of the drive shaft (24) to the aiming optics (16). <IMAGE>
