Abstract: A three wheel electric vehicle platform with two wheels in front and one wheel at the rear, a full safety roll cage, a propulsion and steering system operating through the two front wheels, and operator's and passenger's seats mounted in-line along the vehicle centerline. The propulsion system is an electric motor powered by an energy storage device driving a speed reduction and differential with dual outputs suitable for two wheel front drive. The operator's seat is narrower in parts than a conventional automotive seat such that the rear seat passenger's knees can comfortably straddle the operator seat to allow the distance between the two occupants to be less than a typical automobile. The driver's and passenger's heels comfortably fit into recessed wells within the energy storage device, thus allowing the driver's and passenger's center of gravity to be lower, while still maintaining a comfortable sitting position.

Abstract: A center mounted power train configuration for a high water speed tracked amphibious vehicle which mounts the engine above the waterjet inlet plenum to shorten the power train length, so as to allow the vehicle length and weight to be optimized for land and water mobility. The short power train length provides for use of alternate longer components which may be required to obtain adequate power and thrust. Center mounting the power train reduces air ingestion into the waterjets and maximizes the sharing of support structure to lighten the vehicle. Center mounting of the power train also optimizes efficiency by using one propulsion gearbox to transfer power and improves access to components for repair or replacement. The power train arrangement features a rearward center of gravity for enhanced land and water mobility and provides space for locating personnel, for mission equipment and for access to floor level suspension components.
