A multiple directional wheel including a wheel frame comprising identical component parts. Each of the wheel frame components comprise: a hub having a main axis about which the multiple directional wheel is adapted to rotate; a hub rim radially surrounding the hub; a first plurality (four shown) of peripheral roller supporting arms (“first arms”) radially extending from the hub rim and aligned in a first plane; and a second plurality of peripheral roller supporting arms (“second arms”), each member arm of the second plurality of peripheral roller supporting arms having a radially inner base and being circumferentially offset with respect to diagonally adjacent members of the first plurality of peripheral roller supporting arms. Each of the wheel frame components further comprise a plurality of beams corresponding to the number of member arms of the second plurality of peripheral roller supporting arms, each respective beam extending from the hub rim to a corresponding inner base of a member arm of the second plurality of peripheral roller supporting arms, and a plurality of spigots extending from each corresponding one of the plurality of beams or the inner bases. The second plurality of peripheral roller supporting arms lie in a second plane normal to the main axis, spaced from, and parallel to, the first plane; and each of the spigots from one of the wheel frame components is received in a recess formed in a facing surface of a complementary one of the wheel frame components to join the wheel frame components to form the wheel frame.

A wheel bearing having a cup, a cone and a washer. The cone is of a complementary shape to the cup and the washer abuts a surface of the cone. Each of the cup, the cone and the washer are made from a self-lubricating polymer.

A magnetic wheel includes: a balance block; a magnetic body which is provided in the balance block and attaches the balance block to an attachment object with a magnetic force; and a magnetic shielding block which is provided in the balance block and guides a magnetic field generated in the magnetic body toward the attachment object.

An annular support structure for a track vehicle is disclosed herein. The annular support structure includes a first piece and a second piece. The first piece includes a first hub portion, a first web extending radially outward from the first hub portion, and a first outer body extending radially outward from the first web. The second piece includes a second hub portion, a second web extending radially outward from the second hub portion, and a second outer body extending radially outward from the second web. The first piece and the second piece joined together at an inner joint located proximate to the first hub portion and the second hub portion and the first piece and the second piece adjacent to each other at an outer joint located proximate to the first outer body and the second outer body.

An omni-directional wheel for a pool vacuum head includes a first frame and a second substantially identical frame, each frame having a hub rotating around a common axis, lower supports extending radially from the hub, risers extending from the hub along the common axis, and upper supports individually coupled to the risers, the upper supports extending radially from the common axis. Rollers coupled to the first frame and the second frame, are radially spaced from the common axis on each frame. The rollers rotate normal to the common axis to impart omni-directional movement. When the first frame and the second frame are interlocked, the risers on the first frame engage the hub on the second frame, and the lower supports on the first frame engaging the upper supports on the second frame, maintaining the rollers in a staggered arrangement around the wheel.

A wheel of a roller includes a roller axis, the wheel being driven by an electric motor, wherein the electric motor is a hub motor which drives a hub body, which extends with circumferential spacing and surrounds the wheel axle, relative to the fixed wheel axle, wherein furthermore the wheel has a running surface. The running surface is formed on a running surface carrier and the running surface carrier is supported flush on the hub body at the back of the running surface. Further, a manually movable load truck includes one or more rollers, of which at least one roller has a driven wheel. Further, an operating device, in particular for a manually movable load truck, is formed having a substantially annular cross-section having a central through opening.
