Provided is a power generation system capable of efficiently converting wind power into electric power. The power generation system comprises: a pneumatic tire; a wheel on which the pneumatic tire is mounted; and at least one generator wind turbine attached, in a cavity defined by the pneumatic tire and the wheel, to the pneumatic tire and/or the wheel.

Emblem for vehicles, comprising a decoration layer; at least one lighting element that illuminates the decoration layer; an electrical power generator that feeds electric power to the at least one lighting element, wherein the electrical power generator includes a rotor comprising a support disc for at least one magnet; and a stator comprising at least one printed circuit board provided with windings. It permits to provide an emblem in which a power generator is optimized to be compatible in the axial direction with the available space, which is very small behind the front cover.

A wheel assembly is configured to display graphic designs and digital information. The wheel assembly has a wheel, joined to a spinner hub with a spinner base. A weight is joined to a spinner base lower portion. A spacer is joined to the spinner base above the weight. A bracket is joined to the spinner base and arranged against the spacer. A mobile device is housed within the bracket. A cover plate is joined to the spinner base, and further comprises a central opening with graphic designs that surrounds the bracket. As the wheel rotates, the weight causes the spinner base rotate opposite the wheel thus maintaining the mobile device in a stable position so that the mobile device displays the digital information.

The invention relates to a vehicle wheel comprising a wheel rim (12) that has a hub portion (38), a rim base (36) for receiving a tire, a plurality of support portions (40) interposed between the hub portion (38) and the rim base (36), at least one interspace (42) between the support portions (40), and at least one cover element (44) associated with the interspace (42), characterized in that the cover element (44) can be transferred from a first position to a second position by pneumatic actuation.

A wheel rim assembly for a wheel of a motor vehicle may include a wheel rim and a cover portion arranged on an outside of the wheel rim. The cover portion may be guided on the wheel rim so as to be movable relative to the wheel rim between an open position allowing an air flow between the outside and an inside of the wheel rim, and a closed position preventing the air flow. Conversion from the open position to the closed position takes place automatically based on an operating state of the wheel. The cover portion may be configured as a disc-like component covering the outside. The cover portion may be arranged movably parallel to an axis of the wheel rim between the open position and the closed position, in the open position opening a ring gap between an edge of the cover portion and the wheel rim.

A variable aerodynamic wheel includes: a spoke wheel having a plurality of spokes connecting a hub and a rim together are spaced apart from each other, and a plurality of through spaces defined between the plurality of spokes to allow air to pass therethrough; a variable flap rotatably disposed in the plurality of through spaces of the spoke wheel, and configured in a shape to cover an associated through space so as to open or close the associated through space according to a rotation angle thereof; and a drive unit disposed in the spoke wheel, and connected to the variable flap such that the rotation angle of the variable flap is adjusted as rotational power is transmitted.

The improved mobile robot utilizes a cooperative wheeled support arrangement having a unique axle design that preferably cooperates with a base support module. A tri-axle is preferably used to support at least one omni-wheel on each axle section. Multiple omni-wheels on each section can be used for higher load applications. The tri-axle is of a fixed design and each wheel pivots on the individual axle section. Preferably, the axle sections are welded to each other.
