发明名称 ARTICULATED WHEEL ASSEMBLIES AND VEHICLES THEREWITH
摘要 The disclosed articulated wheel assemblies and associated vehicles, for example wheelchairs, include articulated wheel assemblies with at least one offset connecting arm rotatably attached at one end to a payload platform, for example a seat, and attached at the other end to a linear actuator, where the linear actuator is further connected to a wheel. Embodiments include a rotary actuator for varying the linear actuator swing angle, a rotary actuator for eccentrically rotating a hubless wheel, a linear actuator motor for varying the length of the linear actuator, and a propulsion motor. Embodiments provide omnidirectional motion, stepping action when presented with obstacles, irregular surface negotiation, tight space maneuvering and other features to provide disabled people increased mobility. Alternate embodiments include a payload platform with a support strut, which is rotatably attached to an offset connecting arm and pivotally mounted to a seat.
