Title:
A COMPACT GROUND VEHICLE WITH ELECTRIC PROPULSION
Document Type and Number:
WIPO Patent Application WO/2023/041942
Kind Code:
A3
Abstract:
A biwheel has large left and right main wheels (1, 2) supported by suspension assemblies (7) acting between rims of each main wheel and a payload carrying cockpit (3) suspended above the ground between the wheels. The arrangement facilitates access to the cockpit payload space through the wheels. Each wheel is cambered to deter pitching motion of the cockpit within the wheel. A rear jockey wheel (61) is provided to further deter pitching. Propulsion to the wheels is via electric motors built into drive wheels (16) which are mounted onto a suspension assembly (7). The torque applied to the electric motors can be controlled by a digital control system responsive to sensors such as a cockpit attitude sensor, to further deter pitching motion of the cockpit. Propulsion may additionally be delivered by a manual propulsion system supplemented by the electric motors.
