Abstract
A wheel capable of changing traction surface and track by varying the usual axis of rotation. The amount of this contacting surface can be varied and the path can be varied from usual linear to curvilinear contact. Full X, Y, and Z operation is characterized by largely symmetrically curved sinoisoidal-like motion.
Claims49
A traction enhancing wheel and support assembly comprising:
- a wheel,
- a wheel support,
- a coupling means between said wheel and said wheel support for allowing movement of said wheel relative to said support in the transverse horizontal and vertical planes,
- a first actuator connected between said wheel and said wheel support for controlling movement of said wheel is said transverse horizontal plane,
- a second actuator connected between said wheel and said wheel support for controlling movement of said wheel in said transverse vertical plane,
- and control means adapted to move each of said actuators to allow said wheel to move along a predetermined path of travel.
