ABSTRACT:
A peripatetic vehicle, the suspension of which includes a bogie carrying two main wheels, one to either side of the vehicle, and caster wheels. The stability of the suspension is completed by further casters, supported from the body of the vehicle. The use of the bogie improves the ride of the vehicle over rough ground, and the use of only two main wheels, the rest being casters, gives high maneuverability. The main wheels may be driven, e.g. by separate motors, and the vehicle steered by driving these wheels differentially. Stable steering is improved by locating the transverse axis of the main wheels closely beneath the center of mass of the loaded vehicle.
