Novel tracked relief vehicle gets in
gear
An amphibious multiterrain tracked vehicle under development by ARIS of Italy will use David Brown gear technology.
An amphibious multiterrain tracked vehicle under development by ARIS of Italy to fulfil disaster relief and defence support roles is employing David Brown gear technology within its tracked drive system and to transfer power to hydraulic pumps in the marine propulsion system The A.R.I.S Ark vehicle employs a fully automated gearbox and power take-off linked to the vehicle's 300hp diesel engine; a transmission and control system designed and built by David Brown Engineering, part of Textron Fluid and Power

The historic Ponce de Leon Inlet Lighthouse in Florida has taken a turn for the better thanks to the combined efforts of Miller Bearings and the ultracompact design of David Brown gear technology.
Speed reducers enable switch from hydraulics
Gear technology meets environmental challenge with switch from hydraulics to electromechanical operation.
Based on the chassis of a logistic vehicle derived the widely used M113 armoured personnel carrier, Ark is fully amphibious, providing immense flexibility for roles in flood relief areas where it is capable of tackling the toughest terrain and up to sea state 4.
It is equipped with a tilting bow to stabilise the vehicle in the water and has an aluminium hull with waterproofed engine compartment and a sealed electric system.
Two stern ducts each incorporate a hydrostatically driven propeller operated through the David Brown specially designed and developed power take-off (PTO), which is capable of transferring the full engine power by the engagement of a multiplate clutch fitted within the PTO.
The Ark is capable of handling a 5t payload on land and a 4t payload in water, and its compact size means it can be driven on public roads.
On land the vehicle uses an innovative rubber track system.
David Brown and ARIS are also looking at incorporating the new transmission system into ARIS amphibious vehicles for miliatry and civil protection uses.
