Title:
WELDING SHAFT FOR OMNIDIRECTIONAL WHEEL, WHEEL ASSEMBLY THEREOF, AND OMNIDIRECTIONAL WHEEL
Document Type and Number:
WIPO Patent Application WO/2021/093149
Kind Code:
A1
Abstract:
A welding shaft for an omnidirectional wheel, a wheel assembly thereof, and an omnidirectional wheel. The welding shaft comprises a large wheel welding shaft (7) and a small wheel welding shaft (8). The large wheel welding shaft (7) comprises a large wheel welding shaft body (701), a large wheel welding shaft retaining ring (703), and a large wheel welding shaft fixing head (702) which sequentially constitute an integral member. The small wheel welding shaft (8) comprises a small wheel welding shaft body (801), a small wheel welding shaft retaining ring (803), and a small wheel welding shaft fixing head (802) which sequentially constitute an integral member. The wheel assembly for the omnidirectional wheel comprises a wheel axle fixing plate (6), the welding shaft, a large wheel (4), and a small wheel (5). The omnidirectional wheel comprises an outer guard plate (1), an outer fixing plate (2), a wheel axle drive connecting member (3), the plurality of wheel assemblies, an inner fixing plate (9), an inner guard plate (10), and a plurality of shock absorption assemblies (11). The arrangement is more reasonable, the large wheel (4) and the small wheel (5) can be evenly distributed on the same circumference, the stress is even, the transition is smoother, the steering is more accurate, slipping is not likely to happen, the abrasion is small, the service life is long, and the production cost and the maintenance cost can be reduced.
