QinetiQ has received two contracts from the US Office of Naval Research to develop its proprietary hub drive unit electric propulsion system and long travel suspension for use in armoured reconnaissance vehicles.

The effort leverages the electric hub drive development carried out by QinetiQ for DARPA's Ground X Vehicle Technologies programme.

The QinetiQ electric hub drive unit technology combines a compact electric motor with a multi-stage gear box and integral brake. Its ability to operate at either high output speed or high output torque enables combined improvements in operational and tactical mobility.

Fitting inside a typical standard 20-inch wheel of a combat vehicle, the QinetiQ hub drive is designed to give full military vehicle performance for traction and braking, matching or exceeding conventional drive capability.

The design approach eliminates the restrictions on space taken up by a conventional transmission, as well as hull penetrating drivetrain components. This allows the optimum placement of other key vehicle systems not constrained by the physical space demand and restrictions of mechanical drive where propulsion power

is now handled by electrical cables.

QinetiQ’s long travel suspension concept enables wheel travel of around twice that of a conventional suspension without the need for complex, multi-link systems or configurations used by extreme off-roaders. The concept will enable the vehicle to change mode from a high-ride height IED-resistant standoff stance to rock ‘crawler’ behaviour, and greatly enhances survivability in amphibious operations through improved in-water performance and entry/exit from water.
