A hub arrangement for twin wheels comprises a stationary carrier; an intermediate hub which is rotatable about an axis of rotation and which can be driven by a drive shaft; a differential gear having an input which is connected to the intermediate hub; a first wheel hub which is connected to a first output of the differential gear; and a second wheel hub which is connected to a second output of the differential gear. The hub arrangement furthermore comprises a first braking apparatus which is effective between the stationary carrier and the intermediate hub and a second braking apparatus which is effective between the stationary carrier and the second wheel hub or between the intermediate hub and the second wheel hub. In this respect, the first braking apparatus and the second braking apparatus can be actuated separately from one another.

A wheel for a skateboard may include a bearing assembly, an annular rim coupled to and extending annularly around the bearing assembly, and a tapered tire portion coupled to and extending annularly around the annular rim. A dual wheel assembly may include a first wheel disposed on a longitudinal end portion of an axle, a spacer disposed on the longitudinal end portion of the axle adjacent to the first wheel and abutting against the first wheel, and a second wheel disposed on the longitudinal end portion of the axle adjacent to the spacer and abutting against the spacer. A method of making a dual wheel assembly may include disposing a first wheel on an axle, disposing a spacer on the axle adjacent to the first wheel, and disposing a second wheel on the axle adjacent to the spacer.

A wheel for a pneumatic tire has a rim with one monolithic bead seat and a removable beat seat. The removable bead seat has two halves that embrace the rim and engage a groove to retain the tire. The removable bead seat may have a second lip either monolithically formed or as a part of a separate retainer that bolts to the bead seat. The wheel may be made from aluminum alloy.

The presently claimed invention relates to a road wheel comprising a mounting disc, a dish-shaped transitional wall having an outer edge, a rim with an annular cylindrical wall attached along a first rim edge to the outer edge of the transitional wall, and a stiffening flange attached to the rim along a second rim edge opposite the first rim edge wherein the flange provides radial support to the second rim edge of the cylindrical wall to resist deflection.

A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.
