Title:
OMNIDIRECTIONAL BALL WHEEL
Document Type and Number:
WIPO Patent Application WO/2019/019538
Kind Code:
A1
Abstract:
Disclosed is an omnidirectional ball wheel, comprising a ball wheel framework (110), and at least three first wheels (120) and second wheels (130), wherein the ball wheel framework (110) has a curved outer surface, is pivotable, and has a first pivot axis (101); each of the first wheels (120) has a curved outer surface, is pivotably connected to the ball wheel framework (110), and has a second pivot axis (102); the outer surfaces of the at least three wheels (120) are in the same spherical surface with the outer surface of the ball wheel framework (110), and the second pivot axes (102) are perpendicular to and intersect with the first pivot axis (101); and the top of the outer surface of each of the first wheels (120) is provided with a through hole to accommodate the second wheel (130), the second wheel (130) is pivotably connected to the ball wheel framework (110) and has a third pivot axis (103), the outer surface of the first wheel (120) and a part of the outer surface of the second wheel (130) are in the same spherical surface, and the third pivot axis (103) is perpendicular to both the first pivot axis (101) and the second pivot axis (102). The omnidirectional ball wheel has a small gap, smoother motion and less impact, and does not reduce the effective driven load.
