摘要:
A wheel pad for moving an object across a surface having non-planar obstructions to allow movement of the object across the surface. The wheel pad has a contact pad and a load bearing assembly. The contact pad has an outer skin enclosing a fluid and a torus bearing. The torus bearing has a plurality of bearings, with each adjacent bearing rotatably joined by a connector that allows the bearings to independently rotate. The load bearing assembly has a load transfer mechanism and a load transfer device. The load transfer mechanism has a plurality of recirculating bearings moveably positioned inside a ball chamber. The load transfer device interacts with, but moves independently of, the load transfer mechanism to transfer the weight of the object to the contact pad, which weight is transferred to a lower surface thereof by the fluid and torus bearing to provide omnidirectional movement for the wheel pad.
