| 20090179480 | Vehicle Wheel for a Double-Track Vehicle or Cover Therefor - The invention relates to a vehicle wheel for a double-track vehicle or an external cover therefor, having passage openings, particularly for a cooling air flow for a wheel brake provided on the interior side of the wheel, in the lateral projection, the passage openings having a width in the radial direction which changes when viewed in the circumferential direction such that, viewed against the rotating direction of the wheel when the vehicle is driving forward, the above-mentioned width decreases, and in that the—viewed in the radial direction—centers of the virtual segments of the passage opening which follow one another against the rotating direction move quasi (virtually) in the direction of the wheel center. As a result, the force as well as the lever arm of the drag is reduced, so that a moment of resistance is obtained which is significantly decreased. The passage openings are preferably bounded by spokes extending essentially in the radial direction. | 07-16-2009 |
| 20100187897 | VENTILATED WHEEL ASSEMBLY - The wheel assembly comprises a wheel having an axis X-X′ and a system for braking the wheel. A fan is arranged in the space of the wheel in order to draw in the flow of hot air ( | 07-29-2010 |
| 20120080932 | RIM - A rim is provided for a motor vehicle wheel that includes, but is not limited to a rim ring for receiving a tire, a rim hub for fastening to a shaft and a plurality of rim struts each connected to the rim ring and to the rim hub. Between each two adjacent rim struts a cooling opening is formed, and the rim hub and/or the rim ring and/or the rim strut includes, but is not limited to at least one fastening for the releasable connection to a flow guide plate for guiding headwind. Because of this, a rim of simple design configuration is created, which with a low aerodynamic resistance makes possible good cooling of a brake unit. | 04-05-2012 |
| 20140159468 | In-wheel motor with brake - The invention relates to wheel for a vehicle comprising, inside the wheel:

| 20090195053 | RIM OR WHEEL ADD-ON PART FOR A MOTOR VEHICLE WHEEL HAVING CLOSABLE OPENINGS - A part (e.g., a rim) of a wheel of a motor vehicle is provided that has closable ventilation openings which may have flow through them in the open state in the axial direction to the wheel axle, an actuator being provided which is implemented to open and close the ventilation openings. | 08-06-2009 |
| 20150108823 | PROPULSION WHEEL MOTOR FOR AN ELECTRIC VEHICLE - A wheel assembly for an electric vehicle includes a wheel rim that is concentrically disposed about a central axis. A propulsion-braking module is disposed within an interior region of the wheel rim. The propulsion-braking module rotatably supports the wheel rim for rotation about the central axis. The propulsion-braking module includes a liquid cooled electric motor having a rotor rotatable about the central axis, and a stator disposed radially inside the rotor relative to the central axis. A motor-wheel interface hub is fixedly attached to the wheel rim, and is directly attached to the rotor for rotation with the rotor. The motor-wheel interface hub directly transmits torque from the electric motor to the wheel rim at a 1:1 ratio. The propulsion-braking module includes a drum brake system having an electric motor that rotates a cam device, which actuates the brake shoes. | 04-23-2015 |
| 20150298502 | POWER TRANSMISSION DEVICE - A power transmission device includes: a spindle case that includes a central hole through which an axle shaft penetrates in a central portion and forms a brake chamber in a region around the axle shaft at a base end portion; a wheel hub that is rotatably supported by an outer circumference of the spindle case and includes a final chamber, between the final chamber and the brake chamber, oil can flow, by communicating with the brake chamber through the central hole of the spindle case; a wet type brake mechanism that is contained in the brake chamber and operates so as to apply braking on rotation of the axle shaft with respect to the spindle case; and a deceleration mechanism that is contained in the final chamber and decelerates the rotation of the axle shaft to transmit the rotation to the wheel hub. | 10-22-2015 |
