Abstract
A compact, low profile omnidirectional drive and steering unit that, in one embodiment, utilizes a single, centrally located wheel, mounted on a drive shaft, upon which is also mounted a tapered pinion gear. The pinion gear on the drive shaft meshes with a ring shaped beveled worm gear contained within the outer housing of the gear unit that surrounds the centrally located wheel. At one side of the outer housing is a worm drive that meshes with the ring shaped and beveled worm gear. Rotation of the worm drive causes rotation of the ring shaped worm gear, which causes the drive shaft mounted pinion gear to turn, which turns the drive wheel to provide driving power for whatever vehicle or system of which the unit is a part. A steering and timing gear is mounted on the lower surface of the unit to provide steering capability.
